Manufacturing Manual
Information provided in this written material should not be considered as all-encompassing, or
suitable for all situations, conditions or environments. Each company is responsible for
implementing their own safety/injury/illness prevention program and should consult with their
legal, medical or other advisors as to the suitability of using this information. Application of this
information does not guarantee you will be successful in your safety efforts, or that the information
will meet Federal OSHA standards or requirements. At the time this information was provided, it
was believed to be from reliable sources and current with applicable local, state or federal safety
standards, however, the producers of the program assume no liability arising from the use of, or
reliance on the information provided. Always seek the advice of your legal, medical or other
advisors as necessary before using this information in your Company's safety efforts.
We have provided this Manual on disk, so you may remove information that may not be applicable
to your operations. Admittedly, there is more information in this Manual than may be required.
You may also want to add information we may not have included. It is recommended that you
place your name and address as” HEADER OR FOOTER”, to more personalize the Manual.
Where we have (COMPANY NAME), simply go to the Word format EDIT file in the top menu,
then the REPLACE file. Click the box that says REPLACE. On the “find what” box, type in
(COMPANY NAME). In the “replace with” box, type your company name. Then click on
“replace all”. This will remove (COMPANY NAME) and will replace it with your company’s
name. On the CD-ROM disk, there is a separate section for OSHA RECORDKEEPING, which is
valuable information relating to OSHA RECORDKEEPING REQUIREMENTS. Even if you
have no injuries to report, you must POST the OSHA Log 200 where employees may see it, for
the entire month of February each month.
For the MANUFACTURING industry, you should have the following minimum written plans:
• CONFINED SPACE ENTRY, PERMIT-ENTRY (if you have confined spaces)
• RESPIRATORY PROTECTION PROGRAM (if you use respirators)
You must be able to show, through documentation, that your company enforces safety. This is one
reason why we included SAFETY COUNSELINGS in this manual. Unless you can show that you do
enforce safety, you do not have an EFFECTIVE safety program. Basically, there are several elements
of an effective safety program that must be PROVEN THROUGH DOCUMENTATION, should your
company be engaged in a legal dispute:
Written safety policies and procedures.
Employees must be trained in these policies and procedures. (training documentation).
Safety policies and procedures must be enforced. How do you prove your policies/procedures are
enforced? Documentation of disciplinary action taken on those individuals who violate company
safety policies/procedures. This can come in the form of “safety counseling”. You simply cannot
say that no employee has ever violated a safety rule, policy or procedure. That won’t fly.
This manual addresses many of mandated requirements, however, you must edit the manual/plan to make the
written plans “site specific”, which means specifically for your organization; your equipment, your facilities and
your employees. A “canned manual” is worthless unless it is edited and changed to fit your operations. Some of
the information may be outdated or incorrect for your company and operations, so it’s your responsibility to add,
delete and improve on these guidelines. ANY pre-written manual, such as this one, is good only as GUIDE.
Don’t just put your name on it and call it your written plan. It is not your written plan or plans until you have
made it fit your company/operations. Take your time and learn the requirements and make sure you have
proper documentation to support your program. If you don’t have documentation, you don’t have a plan.
Note: You should remove the preceding information (pages 1 and 2) before printing out your “manual”. Be sure
you have repaginated your manual as so desired, since you will have deleted and added information, therefore the
pages may not be in a correct format. The original manual begins on page 3 here, so if you delete these first two
pages and repaginate, your manual begins on page one. We have not included a table of contents, as page
numbers will change because of the deletions/additions.

"One of the principles of sound business management is the control of all factors which have a
bearing on "incidents of loss". Whenever there is a personal injury or damage to property,
from whatever cause, it is a direct reflection on our ability to perform our work in a correct and
conscientious manner.
To help insure your continued good health and that of visitors to our offices/facilities, we are
adopting and sponsoring a program of action dedicated to the reduction or elimination of
causes for loss. In accepting this responsibility, management requests unqualified cooperation
from every employee.
Our basic safety policy for all employees is simply stated:
We recognize our responsibility in safety matters and shall endeavor to do our part in
maintaining a safe and healthy place to work. The employer has the legal and moral obligation
to provide a safe and healthful work environment, consequently each and every employee, as a
condition of employment, has the obligation to work in a safe and healthful and productive
manner. Safety is a team effort, requiring the diligence of all levels of management,
supervision and employees.
The following named person is hereby appointed as Safety Coordinator:
The following named person is hereby designated as Acting Safety Coordinator, in the absence
of the appointed Safety Coordinator:
The duties of the Safety Coordinator are to consult with management and other employees, on
all aspects of safety and health, and to properly maintain records, training documentation, and
hazard identification/correction as deemed necessary by management. Specific duties are to be
outlined by management in an appropriate job description or other method prescribed by
management. The Safety Coordinator's job is to COORDINATE safety efforts; however, the
RESPONSIBILITY for the safety program remains upon management and supervision.
Responsibility for individual safety is the responsibility of each employee.
Each employee should be the person most concerned for his/her own safety.
In addition, each employee has a responsibility to assure safety and health on the job, for the
general public and other employees. By accepting employment, each employee is accepting
safety responsibility as a condition of continued employment:
Knowing his/her job and applying safe work practices.
Recognizing the hazards of the job and taking precautions to assure the safety of the
employee and others.
Informing your department head or the Safety Coordinator of hazards and recommending
how to eliminate them or improve performance.
Actively participating and cooperating in the overall safety program.
Maintaining cleanliness and good personal health habits.
Each employee has the responsibility to communicate with management, openly and
without fear of reprisal, any aspect of safety and health, specifically to make
recommendations for safety and health improvement in the facilities, equipment and
procedures. Each employee has the responsibility to report to management any safety or
health hazard, so it may be corrected to prevent injury or illness.
Each employee has the responsibility to work and act safely at all times, on all jobs, every
1. PERSONAL HYGIENE. Be fit for the job by developing healthy habits, eating proper
meals, getting sufficient rest, and guaranteeing cleanliness.
2. KNOW YOUR JOB AND RESPONSIBILITIES. You learn the proper way by asking,
not by trial and error. Communicate suggestions to management, on better and safer
methods of improving job safety and health. Be conscious of the safety of others, as well
as your own. If you see a hazard, correct it if possible, even if it's not in your department.
For those hazards you cannot immediately correct, notify your supervisor, so the hazard
can be corrected.
3. CLOTHING. Wear proper, acceptable clothing for the job. If you're not sure of what
clothing is acceptable, ask your supervisor. Rings and jewelry should not be worn on,
around, or near moving machinery. Long hair must be kept tied back or confined under a
cap or hat to prevent long hair from entanglements with machinery or equipment.
4. PROTECTIVE CLOTHING OR EQUIPMENT. Although routine tasks performed by
employees may not require personal protective equipment, there may be times on the job,
in the facilities, or off site, where personal protective clothing/equipment is necessary.
When management prescribes and provides personal protection items, each employee has
an obligation to use the personal protective equipment.
5. HOUSEKEEPING. A place for everything and everything in its place. Keep equipment,
tools, materials, and work areas clean and orderly. Particular attention must be paid to
electrical cables/wires and other tripping hazards. If debris, leaks, or any other potential
hazards are identified, it's up to each individual who notices such hazards to correct them.
If this is not possible, notify supervision or management, so the hazard may be corrected.
All hazardous materials must be properly stored, according to company requirements.
6. MACHINE GUARDING. Any machine that has exposed hazardous parts must be
properly guarded. Should any machine or equipment have guards removed, or require
guarding, that equipment will not be used until it has been properly guarded. Employees
are not to use equipment or machinery that is not adequately guarded. Should equipment
or machinery be locked or tagged out, with words such as: "Danger-Do Not Start
Machine". The machine being repaired, serviced or otherwise out of service, must not be
started or tampered with while the lock or tag is in place. Only the person installing the
lock or tag is authorized to remove the lock or tag.
7. MOVEMENT. Walk, never run. Use handrails on stairs. Be cautious when approaching
swinging doors, corners, or congested areas. Particular attention should be devoted to the
prevention of slips and falls, particularly when carrying materials, equipment or tools.
Most slips and falls are the result of not watching where a person is walking or inattention
to footing.
8. SAFE LIFTING. Each employee has been, or will be trained in the safe lifting method.
Each employee must exercise these techniques and methods when lifting anything. If at
anytime, an employee believes an object is too heavy or awkward to be lifted by one
person, then he is expected to get help or move the object by mechanical lifting means.
Each employee should maintain adequate fitness to keep the back healthy, thereby
reducing the exposure to back injuries.
9. HORSEPLAY/PRACTICAL JOKES. Practical jokes, horseplay, and similar activities are
strictly prohibited. Each employee has the responsibility to behavior in a professional
manner at all times.
10. FIRE PREPAREDNESS. Know what to do, what action to take, and where to go in the
event of an emergency. In the event of a fire, life safety is of paramount importance. If
you have been trained and can safely extinguish a fire, use portable fire extinguishers, but
only if there is no danger to your life. In the event of a fire, always call the fire department,
even if the fire can be extinguished. It's best to have the fire department notified, in case
the fire gets out of control. The company must provide written emergency procedures,
must verify inspection of all fire extinguishers on a monthly basis, with annual inspections
required by a fire service company, and must document all inspections and services.
11. EMERGENCY PREPAREDNESS In the event of an earthquake, tornado, or similar
emergency, the best advice is to DUCK, COVER, and HOLD. Duck under a desk or
sturdy workbench, cover to protect your head, eyes and other body parts from falling
equipment or broken glass. Never run out of the building, since power lines are located in
the proximity of our facilities. Flying glass from windows could be another hazard.
Follow emergency procedures and use common sense to protect yourself and property.
Report all work-related accidents, injuries or illnesses to management WHEN THEY
OCCUR. First aid facilities are available and when required, competent medical assistance
will be provided. Worker compensation insurance will cover all medical costs for injuries that
are work related. Report all accidents, injuries and illnesses when they occur, even if you don't
think medical treatment is required.
The Occupational Safety and Health Administration (OSHA) has concluded that effective
management of worker safety and health protection is a decisive factor in reducing the extent and
the severity of work-related injuries and illnesses. Effective management addresses all work-related
hazards, including those potential hazards, which could result from a change in worksite conditions
or practices. It addresses hazards whether or not they are regulated by government standards.
The language in these guidelines is general, so it may be broadly applied in general industry,
regardless of the size, nature, or complexity of operations. The guidelines consist of program
elements, a distillation of applied safety, and health management practices used by employers who
are successful in protecting the safety and health of their employees. Many safety and health
professionals and consultants advocate these program elements. They are strongly endorsed by
individuals, corporations, professional associations, and labor representatives who responded to the
OSHA request for comments and information regarding these guidelines.
Management has an obligation and responsibility to all employees to enforce safety rules. The
vast majority of work related injuries are caused by the unsafe acts, such as carelessness,
negligence, violation of safety rules, taking short cuts or not following proper procedures.
When an investigation reveals the cause of an incident was a result of the unsafe acts of an
employee(s), that employee(s) will be given a written counseling as to the behavior that
contributed to the cause of the incident and the action that must be taken by the employee to
eliminate this behavior. A time frame in which to correct the unsafe behavior will be given the
employee. This counseling should be viewed as TRAINING. Understanding the cause of the
incident is essential and then what the employee should do to correct the unsafe behavior
should follow. Without this information, the employee would not know why the incident
occurred and would have no reason to change his/her behavior.
A safety counseling is not disciplinary action, however, continued demonstration of unsafe
behavior could result in disciplinary action, up to and including termination.
In the context of SAFETY, a written counseling for violation of safety rules, unsafe acts or
unsafe behavior is of unparalleled value. To ease the temperament of the person receiving a
written counseling for safety violations, the best thing to do is call the written counseling a
No one wants to get a disciplinary written counseling in their file; however, if you re-title it:
SAFETY COUNSELING, it becomes a bit more palatable to the employee, as well as being
viewed as an individual recurrent training by any auditing agency. Safety counseling is
designed to explain to the employee what behavior(s) or unsafe act(s) may have contributed to
the accident or injury, in which the employee may had been involved.
Safety counseling is designed to promote safety awareness and improve prevention of injuries and
illnesses. It's designed primarily to explain to the employee, how his/her unsafe behavior or unsafe act
contributed to an accident, injury or illness. Continued demonstration of unsafe acts or unsafe behavior
may lead to disciplinary action.

Management will provide safety training, as necessary. Employees are responsible for
obtaining proper training as may be necessary to adequately educate themselves in the safe
work practices required to prevent all accidents, injuries and illnesses. Generally, safety
training includes, but is not limited to the following:
Employee Safety Orientation.
Safe Lifting/Back Injury Prevention.
Earthquake Safety.
Fire Extinguisher Operations and Safety.
Chemical Safety.
A. Hazard Communications/Right to Know.
B. Ladder Safety.
C. Eye Protection.
D. Personal Protective Equipment.
E. Office Safety.
F. Specific Equipment/Machinery Operations.
G. Video Display Terminals/Computers.
H. Control of Hazardous Energy Sources/Lockout-Tagout.
I. Bonding and Grounding of Flammable Liquids.
J. Forklift Operations
K. Confined Spaces
Each Company must determine the training is necessary, based upon their equipment, hazard
exposure, and potential hazards. When the employee will be exposed to specific hazards,
additional training, such as servicing tires/wheels, respiratory protection, chemicals or other
hazards, will be provided
Employees will not be permitted to operate machinery, equipment or expose themselves to
hazards without proper training. If an employee is not sure of a hazard, or has any questions
regarding the safety and health of any job assigned, that employee must not perform the job
until such time as adequate training is provided.
equipment or machinery. If you are assigned to jobs or tasks with which you are
unfamiliar, or haven't been properly trained, do not accept the job or task until you're
satisfied that you have been properly trained and understand the potential hazards of the job
or task.

Guidelines for Employer Compliance
The Hazard Communication Standard (HCS) is based on a simple concept-that employees have
both a need and a right to know the hazards and identities of the chemicals they are exposed to
when working. They also need to know what protective measures are available to prevent adverse
effects from occurring. The HCS is designed to provide employees with the information they need.
Knowledge acquired under the HCS will help employers provide safer workplaces for their
employees. When employees have information about the chemicals being used, they can take steps
to reduce exposures, substitute less hazardous materials, and establish proper work practices. These
efforts will help prevent the occurrence of work-related illnesses and injuries caused by chemicals.
The HCS addresses the issues of evaluating and communicating hazards to workers. Evaluation of
chemical hazards involves a number of technical concepts and is a process that requires the
professional judgment of experienced experts. HCS is designed so that employers who simply use
chemicals, rather than produce or import them, are not required to evaluate the hazards of those
chemicals. Hazard determination is the responsibility of the producers and importers of the
materials. Producers and importers of chemicals are then required to provide the hazard
information to employers that purchase their products.
Employers that don't produce or import chemicals need only focus on those parts of the rule that
deal with establishing a workplace program and communicating information to their workers. This
appendix is a general guide for such employers to help them determine what's required under the
rule. It does not supplant or substitute for the regulatory provisions, but rather provides a simplified
outline of the steps an average employer would follow to meet those requirements.
1. Becoming familiar with the rules.
OSHA has provided a simple summary of the HCS in a pamphlet entitled "Chemical Hazard
Communication," OSHA Publication Number 3084. Some employers prefer to begin to become
familiar with the rule's requirements by reading this pamphlet. A copy may be obtained from your
local OSHA Area Office, or by contacting the OSHA Publications Office at (202) 523-9667.
The standard is long, and some parts of it are technical, but the basic concepts are simple. In fact,
the requirements reflect what many employers have been doing for years. You may find that you
are already largely in compliance with many of the provisions, and will simply have to modify your
existing programs somewhat. If you are operating in an OSHA-approved State Plan State, you must
comply with the State's requirements, which may be different than those of the Federal rule. Many
of the State Plan States had hazard communication or "right-to-know" laws prior to promulgation
of the Federal rule. Employers in State Plan States should contact their State OSHA offices for
more information regarding applicable requirements.
The HCS requires information to be prepared and transmitted regarding all hazardous chemicals.
The HCS covers both physical hazards (such as flammability) and health hazards (such as
irritation, lung damage, and cancer). Most chemicals used in the workplace have some hazard
potential and thus will be covered by the rule.
One difference between this rule and many others adopted by OSHA is that this one is
performance-oriented. That means that you have the flexibility to adapt the rule to the needs of
your workplace, rather than having to follow specific, rigid requirements. It also means that you
have to exercise more judgment to implement an appropriate and effective program.
The standard's design is simple. Chemical manufacturers and importers must evaluate the hazards
of the chemicals they produce or import. Using that information, they must then prepare labels for
containers, and more detailed technical bulletins called material safety data sheets (MSDS).
Chemical manufacturers, importers, and distributors of hazardous chemicals are all required to
provide the appropriate labels and material safety data sheets to the employers to which they ship
the chemicals. The information is to be provided automatically. Every container of hazardous
chemicals you receive must be labeled, tagged, or marked with the required information. Your
suppliers must also send you a properly completed material safety data sheet (MSDS) at the time of
the first shipment of the chemical, and with the next shipment after the MSDS is updated with new
and significant information about the hazards.
You can rely on the information received from your suppliers. You have no independent duty to
analyze the chemical or evaluate the hazards of it.
Employers that "use" hazardous chemicals must have a program to ensure the information is
provided to exposed employees. "Use" means to package, handle, react, or transfer. This is an
intentionally broad scope, and includes any situation where a chemical is present in such a way that
employees may be exposed under normal conditions of use or in a foreseeable emergency.
The requirements of the rule that deal specifically with the hazard communication program are
found in the standard in paragraphs (e), written hazard communication program; (f), labels and
other forms of warning; (g), material safety data sheets; and (h), employee information and
training. The requirements of these paragraphs should be the focus of your attention. Concentrate
on becoming familiar with them, using paragraphs (b), scope and application, and (c), definitions,
as references when needed to help explain the provisions.
There are two types of work operations where the coverage of the rule is limited. These are
laboratories and operations where chemicals are only handled in sealed containers (e.g., a
warehouse). The limited provisions for these workplaces can be found in paragraph (b), scope and
application. Basically, employers having these types of work operations need only keep labels on
containers as they are received; maintain material safety data sheets that are received, and give
employees access to them; and provide information and training for employees. Employers do not
have to have written hazard communication programs and lists of chemicals for these types of
The limited coverage of laboratories and sealed container operations addresses the obligation of an
employer to the workers in the operations involved, and does not affect the employer's duties as a
distributor of chemicals. For example, a distributor may have warehouse operations where
employees would be protected under the limited sealed container provisions. In this situation,
requirements for obtaining and maintaining MSDSs are limited to providing access to those
received with containers while the substance is in the workplace, and requesting MSDSs when
employees request access for those not received with the containers. As a distributor of hazardous
chemicals, that employer will still have responsibilities for providing MSDSs to downstream
customers at the time of the first shipment and when the MSDS is updated. Therefore, although
they may not be required for the employees in their work operation, the distributor may,
nevertheless, have to have MSDSs to satisfy other requirements of the rule.
2. Identifying responsible staff.
Hazard communication is going to be a continuing program in your facility. Compliance with the
HCS is not a "one shot deal." In order to have a successful program, it will be necessary to assign
responsibility for both the initial and ongoing activities that have to be undertaken to comply with
the rule. In some cases, these activities may already be part of current job assignments. For
example, site supervisors are frequently responsible for on-the-job training sessions. Early
identification of the responsible employees, and involvement of them in the development of your
plan of action, will result in a more effective program design. Evaluation of the effectiveness of
your program will also be enhanced by involvement of affected employees.
For any safety and health program, success depends on commitment at every level of the
organization. This is particularly true for hazard communication, where success requires a change
in behavior. This will only occur if employers understand the program, and are committed to its
success, and if employees are motivated by the people presenting the information to them.
3. Identifying hazardous chemicals in the workplace.
The standard requires a list of hazardous chemicals in the workplace as part of the written hazard
communication program. The list will eventually serve as an inventory of everything for which an
MSDS must be maintained. At this point, however, preparing the list will help you complete the
rest of the program since it will give you some idea of the scope of the program required for
compliance in your facility.
The best way to prepare a comprehensive list is to survey the workplace. Purchasing records may
also help, and certainly employers should establish procedures to ensure that in the future
purchasing procedures result in MSDSs being received before a material is used in the workplace.
The broadest possible perspective should be taken when doing the survey. Sometimes people think
of "chemicals" as being only liquids in containers. The HCS covers chemicals in all physical
forms--liquids, solids, gases, vapors, fumes, and mists--whether they are "contained" or not. The
hazardous nature of the chemical and the potential for exposure are the factors, which determine
whether a chemical is covered. If it's not hazardous, it's not covered. If there is no potential for
exposure (e.g., the chemical is inextricably bound and cannot be released), the rule does not cover
the chemical.
Look around. Identify chemicals in containers, including pipes, but also think about chemicals
generated in the work operations. For example, welding fumes, dusts, and exhaust fumes are all
sources of chemical exposures. Read labels provided by suppliers for hazard information. Make a
list of all chemicals in the workplace that are potentially hazardous. For your own information and
planning, you may also want to note on the list the location(s) of the products within the workplace,
and an indication of the hazards as found on the label. This will help you as you prepare the rest of
your program.
Paragraph (b), scope and application, includes exemptions for various chemicals or workplace
situations. After compiling the complete list of chemicals, you should review paragraph (b) to
determine if any of the items can be eliminated from the list because they are exempted materials.
For example, food, drugs, and cosmetics brought into the workplace for employee consumption are
exempt. So rubbing alcohol in the first aid kit would not be covered.
Once you have compiled as complete a list as possible of the potentially hazardous chemicals in the
workplace, the next step is to determine if you have received material safety data sheets for all of
them. Check your files against the inventory you have just compiled. If any are missing, contact
your supplier and request one. It is a good idea to document these requests, either by copy of a
letter or a note regarding telephone conversations. If you have MSDSs for chemicals that are not on
your list, figure out why. Maybe you don't use the chemical anymore. Or maybe you missed it in
your survey. Some suppliers do provide MSDSs for products that are not hazardous. These do not
have to be maintained by you.
Do not allow employees to use any chemicals for which you have not received an MSDS. The
MSDS provides information you need to ensure proper protective measures are implemented prior
to exposure.
4. Preparing and implementing a hazard communication program.
All workplaces where employees are exposed to hazardous chemicals must have a written plan,
which describes how the standard will be implemented in that facility. Preparation of a plan is not
just a paper exercise--all of the elements must be implemented in the workplace in order to be in
compliance with the rule. See paragraph (e) of the standard for the specific requirements regarding
written hazard communication programs. The only work operations which do not have to comply
with the written plan requirements are laboratories and work operations where employees only
handle chemicals in sealed containers. See paragraph (b), scope and application, for the specific
requirements for these two types of workplaces. The plan is intended to be a blueprint for
implementation of your program--an assurance that all aspects of the requirements have been
The written program has to reflect what you are doing in your workplace. If you use a generic
program, it must be adapted to the facility it covers. For example, the written plan must list the
chemicals present at the site, indicate who is to be responsible for the various aspects of the
program in your facility, and indicate where written materials will be made available to employees.
If OSHA inspects your workplace for compliance with the HCS, the OSHA compliance officer will
ask to see your written plan at the outset of the inspection. The written program must describe how
the requirements for labels and other forms of warning, material safety data sheets, and employee
information and training, are going to be met in your facility.
The following discussion provides the type of information compliance officers will be looking for
to decide whether these elements of the hazard communication program have been properly
A. Labels and other forms of warning.
In-plant containers of hazardous chemicals must be labeled, tagged, or marked with the identity of
the material and appropriate hazard warnings. Chemical manufacturers, importers, and distributors
are required to ensure that every container of hazardous chemicals they ship is appropriately
labeled with such information and with the name and address of the producer or other responsible
party. Employers purchasing chemicals can rely on the labels provided by their suppliers. If the
employer subsequently transfers the material from a labeled container to another container, the
employer will have to label that container unless it is subject to the portable container exemption.
See paragraph (f) for specific labeling requirements.
The primary information to be obtained from an OSHA-required label is an identity for the
material, and appropriate hazard warnings. The identity is any term that appears on the label, the
MSDS, and the list of chemicals, and thus links these three sources of information. The identity
used by the supplier may be a common or trade name ("Black Magic Formula"), or a chemical
name (1,1,1,-trichloroethane). The hazard warning is a brief statement of the hazardous effects of
the chemical ("flammable," "causes lung damage"). Labels frequently contain other information,
such as precautionary measures ("do not use near open flame"), but this information is provided
voluntarily and is not required by the rule. Labels must be legible, and prominently displayed.
There are no specific requirements for size or color, or any specified text.
With these requirements in mind, the compliance officer will be looking for the following types of
information to ensure that labeling will be properly implemented in your facility:
1. Designation of person(s) responsible for ensuring labeling of in-plant containers;
2. Designation of person(s) responsible for ensuring labeling of any shipped containers;
3. Description of labeling system(s) used;
4. Description of written alternatives to labeling of in-plant containers (if used); and,
5. Procedures to review and update label information when necessary.
Employers that are purchasing and using hazardous chemicals, rather than producing or distributing
them, will primarily be concerned with ensuring that every purchased container is labeled. If
materials are transferred into other containers, the employer must ensure that these are labeled as
well, unless they fall under the portable container exemption [paragraph (f)(7)]. In terms of labeling
systems, you can simply choose to use the labels provided by your suppliers on the containers.
These will generally be verbal text labels and do not usually include numerical rating systems or
symbols that require special training. The most important thing to remember is that this is a
continuing duty--all in-plant containers of hazardous chemicals must always be labeled. Therefore,
it is important to designate someone to be responsible for ensuring that the labels are maintained as
required on the containers in your facility and that newly purchased materials are checked for labels
prior to use.
B. Material safety data sheets.
Chemical manufacturers and importers are required to obtain or develop a material safety data
sheet for each hazardous chemical they produce or import. Distributors are responsible for ensuring
that their customers are provided a copy of these MSDSs. Employers must have an MSDS for each
hazardous chemical, which they use. Employers may rely on the information received from their
suppliers. The specific requirements for material safety data sheets are in paragraph (g) of the
There is no specified format for the MSDS under the rule, although there are specific information
requirements. OSHA has developed a non-mandatory format, OSHA Form 174, which may be used
by chemical manufacturers and importers to comply with the rule. The MSDS must be in English.
You are entitled to receive from your supplier a data sheet that includes all of the information
required under the rule. If you do not receive one automatically, you should request one. If you
receive one that is obviously inadequate, with, for example, blank spaces that are not completed,
you should request an appropriately completed one. If your request for a data sheet or for a
corrected data sheet does not produce the information needed, you should contact your local OSHA
Area Office for assistance in obtaining the MSDS.
The role of MSDSs under the rule is to provide detailed information on each hazardous chemical,
including its potential hazardous effects, its physical and chemical characteristics, and
recommendations for appropriate protective measures. This information should be useful to you as
the employer responsible for designing protective programs, as well as to the workers. If you are
not familiar with material safety data sheets and with chemical terminology, you may need to learn
to use them yourself. A glossary of MSDS terms may be helpful in this regard. Generally speaking,
most employers using hazardous chemicals will primarily be concerned with MSDS information
regarding hazardous effects and recommended protective measures. Focus on the sections of the
MSDS that are applicable to your situation.
MSDSs must be readily accessible to employees when they are in their work areas during their
work shifts. This may be accomplished in many different ways. You must decide what is
appropriate for your particular workplace. Some employers keep the MSDSs in a binder in a
central location (e.g., in the pick-up truck on a construction site). Others, particularly in workplaces
with large numbers of chemicals, computerize the information and provide access through
terminals. As long as employees can get the information when they need it, any approach may be
used. The employees must have access to the MSDSs themselves--simply having a system where
the information can be read to them over the phone is only permitted under the mobile worksite
provision, paragraph (g)(9), when employees must travel between workplaces during the shift. In
this situation, they have access to the MSDSs prior to leaving the primary worksite and when they
return, so the telephone system is simply an emergency arrangement.
In order to ensure that you have a current MSDS for each chemical in the plant as required and that
employee access is provided, the compliance officers will be looking for the following types of
information in your written program:
1. Designation of person(s) responsible for obtaining and maintaining the MSDSs;
2. How sheets are maintained in the workplace (e.g., in notebooks in the work area(s) or in a
computer with terminal access), and how employees can obtain access to them when they are in
their work area during the work shift;
3. Procedures to follow when the MSDS is not received at the time of the first shipment;
4. For producers, procedures to update the MSDS when new and significant health information is
found; and,
5. Description of alternatives to actual data sheets in the workplace, if used.
For employers using hazardous chemicals, the most important aspect of the written program in
terms of MSDSs is to ensure that someone is responsible for obtaining and maintaining the MSDSs
for every hazardous chemical in the workplace. The list of hazardous chemicals required to be
maintained as part of the written program will serve as an inventory. As new chemicals are
purchased, the list should be updated. Many companies have found it convenient to include on their
purchase orders the name and address of the person designated in their company to receive MSDSs.
C. Employee information and training.
Each employee who may be "exposed" to hazardous chemicals when working must be provided
information and trained prior to initial assignment to work with a hazardous chemical, and
whenever the hazard changes. "Exposure" or "exposed" under the rule means that "an employee is
subjected to a hazardous chemical in the course of employment through any route of entry
(inhalation, ingestion, skin contact or absorption, etc.) and includes potential (e.g., accidental or
possible) exposure." See paragraph (h) of the standard for specific requirements. Information and
training may be done either by individual chemical, or by categories of hazards (such as
flammability or carcinogenicity). If there are only a few chemicals in the workplace, then you may
want to discuss each one individually. Where there are large numbers of chemicals or the chemicals
change frequently, you will probably want to train generally based on the hazard categories (e.g.,
flammable liquids, corrosive materials, carcinogens). Employees must have access to the
substance-specific information on the labels and MSDSs.
Information and training is a critical part of the hazard communication program. Information
regarding hazards and protective measures are provided to workers through written labels and
material safety data sheets. Through effective information and training, workers will learn to read
and understand such information, determine how it can be obtained and used in their own
workplaces, understand the risks of exposure to the chemicals, and ways to protect themselves.
A properly conducted training program will ensure comprehension and understanding. It is not
sufficient to either just read material to the workers, or simply hand them material to read. You
want to create a climate where workers feel free to ask questions. This will help you to ensure that
the information is understood. You must always remember that the underlying purpose of the HCS
is to reduce the incidence of chemical source illnesses and injuries. This will be accomplished by
modifying behavior through the provision of hazard information and information about protective
measures. If your program works, you and your workers will better understand the chemical
hazards within the workplace. The procedures you establish regarding, for example, purchasing,
storage, and handling of these chemicals will improve, and thereby, reduce the risks to employees
exposed to the chemical hazards involved. Furthermore, your workers' comprehension will be
increased and proper work practices will be followed in your workplace.
If you are going to do the training yourself, you will have to understand the material and be
prepared to motivate the workers to learn. This is not always an easy task, but the benefits are
worth the effort. More information regarding appropriate training can be found in OSHA
Publication No. 2254 which contains voluntary training guidelines prepared by OSHA's Office of
Training and Education. A copy of this document is available from OSHA's Publications Office at
(202) 219-4667.
In reviewing your written program with regard to information and training, the following items
need to be considered:
Designation of person(s) responsible for conducting training;
Format of the program to be used (audiovisuals, classroom instruction, etc.);
Elements of the training program and,
Procedure to train new employees at the time of their initial assignment to work with a
hazardous chemical, and to train employees when a new hazard is introduced into the
The written program should provide enough details about the employer's plans in this area to assess
whether or not a good faith effort is being made to train employees. OSHA does not expect that
every worker will be able to recite all of the information about each chemical in the workplace. In
general, the most important aspects of training under the HCS are to ensure that employees are
aware that they are exposed to hazardous chemicals, that they know how to read and use labels and
material safety data sheets, and that, as a consequence of learning this information, they are
following the appropriate protective measures established by the employer. OSHA compliance
officers will be talking to employees to determine if they have received training, if they know they
are exposed to hazardous chemicals, and if they know where to obtain substance-specific
information on labels and MSDSs.
The rule does not require employers to maintain records of employee training, but many employers
TRAINING. This may help you monitor your own program to ensure that all employees are
appropriately trained. If you already have a training program, you may simply have to supplement
it with whatever additional information is required under the HCS.
An employer can provide employees information and training through whatever means found
appropriate and protective. Although there would always have to be some training on-site (such as
informing employees of the location and availability of the written program and MSDSs),
employee training may be satisfied in part by general training about the requirements of the HCS
and about chemical hazards on the job which is provided by, for example, trade associations,
unions, colleges, and professional schools. In addition, previous training, education and experience
of a worker may relieve the employer of some of the burdens of informing and training that worker.
Regardless of the method relied upon, the employer is always ultimately responsible for ensuring
that employees are adequately trained. If the compliance officer finds that the training is deficient,
the employer will be cited for the deficiency regardless of who actually provided the training on
behalf of the employer.
D. Other requirements.
In addition to these specific items, compliance officers will also be asking the following questions
in assessing the adequacy of the program:
1. Does a list of the hazardous chemicals exist in each work area or at a central location?
2. Are methods the employer will use to inform employees of the hazards of non-routine tasks
3. Are employees informed of the hazards associated with chemicals contained in unlabeled pipes
in their work areas?
4. On multi-employer worksites, has the employer provided other employers with information
about labeling systems and precautionary measures where the other employers have employees
exposed to the initial employer's chemicals?
5. Is the written program made available to employees and their designated representatives? If
your program adequately addresses the means of communicating information to employees in
your workplace, and provides answers to the basic questions outlined above, it will be found to
be in compliance with the rule.
6. Checklist for compliance.
The following checklist will help to ensure you are in compliance with the rule:
Obtain a copy of the rule.
Read and understood the requirements.
Assigned responsibility for tasks.
Prepared an inventory of chemicals.
Ensured containers are labeled.
Obtained MSDS for each chemical.
Prepared written program.
Made MSDSs available to workers.
Conducted training of workers.
Established procedures to maintain current program.
Established procedures to evaluate effectiveness.
(Complete and use the SAMPLE HAZARD COMMUNICATION Plan as your WRITTEN
HAZCOM PLAN, if so desired). The above information is for your study and use relating to
hazard communications.
Slips, trips, and falls constitute the majority of general industry accidents. They cause 15% of all
accidental deaths, and are second only to motor vehicles as a cause of fatalities. The OSHA
standards for walking and working surfaces apply to all permanent places of employment, except
where domestic, mining, or agricultural work only is performed.
Some of the most frequently overlooked general requirements involve housekeeping:
All places of employment, passageways, storerooms, and service rooms shall be kept clean
and orderly and in a sanitary condition.
The floor of every workroom shall be maintained in a clean and, so far as possible, a dry
condition. Where wet processes are used, drainage shall be maintained and gratings, mats,
or raised platforms shall be provided.
Every floor, working place and passageway shall be kept free from protruding nails,
splinters, holes, or loose boards.
Aisles and Passageways
Aisles and passageways shall be kept clear and in good repair with no obstruction across or
in aisles that could create a hazard.
Permanent aisles and passageways shall be appropriately marked.
Where mechanical handling equipment is used, aisles shall be sufficiently wide. Improper
aisle widths coupled with poor housekeeping and vehicle traffic can cause injury to
employees, damage to the equipment and material, and limit egress in emergencies.
Covers and Guardrails
Covers and/or guardrails shall be provided to protect personnel from the hazards of open
pits, tanks, vats, ditches, and the like.
Floor Loading Protection
Load rating limits shall be marked on plates and conspicuously posted. It shall be unlawful to
place, or cause, or permit to be placed, on any floor or roof of a building or other structure, a load
greater than that for which such floor or roof is approved.
Floor openings and holes, wall openings and holes, and the open sides of platforms may create
hazards. People may fall through the openings or over the sides to the level below. Objects, such as
tools or parts, may fall through the holes and strike people or damage machinery on lower levels.
Floor hole. An opening measuring less than 12 inches but more than 1 inch in its least dimension,
in any floor, platform, pavement or yard, through which materials but not persons may fall.
Floor opening. An opening measuring 12 inches or more in its least dimension, in any floor,
platform, pavement, or yard, through which persons may fall.
Platform. A working space for persons, elevated above the surrounding floor or ground.
Wall hole. An opening less than 30 inches but more than 1 inch high, of unrestricted width, in any
wall or partition.
Wall opening. An opening at least 30 inches high and 18 inches wide, in any wall or partition,
through which persons may fall.
Standard railings shall be provided on all exposed sides of a stairway opening, except at the
stairway entrance. For infrequently used stairways, where traffic across the opening prevents the
use of a fixed standard railing, the guard shall consist of a hinged floor opening cover of standard
strength and construction along with removable standard railings on all exposed sides, except at the
stairway entrance.
Standard railing. A standard railing consists of top rail, mid rail, and posts, and shall have a
vertical height of 42 inches nominal from the upper surface of top rail to floor, platform, runway, or
ramp level. Nominal height of mid rail is 21 inches.
Standard toeboard. A "standard toeboard" is 4 inches nominal in vertical height, with not more
than 1/4-inch clearance above floor level.
Floor openings may be covered rather than guarded with rails. When the floor opening cover is
removed, a temporary guardrail shall be in place, or an attendant shall be stationed at the opening
to warn personnel.
Every floor hole into which persons can accidentally walk shall be guarded by either:
A standard railing with toeboard, or
A floor hole cover of standard strength and construction.
While the cover is not in place, the floor hole shall be constantly attended by someone or shall be
protected by a removable standard railing.
Frequently overlooked requirements in walking-working surfaces is the requirement that every
open-sided floor or platform 4 feet or more above adjacent floor or ground level shall be guarded
by a standard railing on all open sides, except where there is an entrance to a ramp, stairway, or
fixed ladder. The railing shall be provided with a toeboard wherever, beneath the open sides:
Persons can pass,
There is moving machinery, or
There is equipment with which falling materials could create a hazard.
Every runway shall be guarded by a standard railing, or the equivalent, on all sides 4 feet or more
above floor or ground level. Wherever tools, machine parts, or materials are likely to be used on the
runway, a toeboard shall also be provided on each exposed side.
Regardless of height, open-sided floors, walkways, platforms, or runways above or adjacent to
dangerous equipment, pickling or galvanizing tanks, degreasing units, and similar hazards shall be
guarded with a standard railing and toeboard.
Every flight of stairs with four or more risers shall have standard stair railings or standard handrails
as specified below. Stair width is measured clear of all obstructions except handrails.
On stairways less than 44 inches wide having both sides enclosed, at least one handrail shall be
affixed, preferably on the right side descending.
On stairways less than 44 inches wide with one open side, at least one stair rail shall be affixed on
the open side.
On stairways less than 44 inches wide having both sides open, two stair rails shall be provided, one
for each side.
On stairways more than 44 inches wide, but less than 88 inches, one handrail shall be provided on
each enclosed side and one stair rail on each open side.
On stairways 88 inches or more in width, one handrail shall be provided on each enclosed side, one
stair rail on each open side, and one intermediate stair rail approximately in the middle of the stairs.
Standard stair railing. A "standard stair railing" (stair rail) shall be of construction similar to a
standard railing, but the vertical height shall be not more than 34 inches nor less than 30 inches
from the upper surface of the top rail to the surface of the tread in line with the face of the riser at
the forward edge of the tread.
Standard handrail. A "standard handrail" consists of a lengthwise member mounted directly on a
wall or partition by means of brackets attached to the lower side of the handrail in order to keep a
smooth, unobstructed surface along the top and both sides of the handrail. They shall hold the rail 3
inches from the wall and be no more than 8 feet apart.
The height of handrails shall be no more than 34 inches nor less than 30 inches from the upper
surface of the handrail to the surface of the tread in line with the face of the riser or to the surface
of the ramp.
Winding stairs shall have a handrail that is offset to prevent people from walking on any portion of
the treads where the width is less than 6 inches.
This section contains specifications for the safe design and construction of fixed general industrial
stairs, including interior and exterior stairs around machinery, tanks, and other equipment, and
stairs leading to or from floors, platforms or pits. This section does not apply to stairs used for fire
exit purposes, to construction operations, to private residences, or to articulated stairs, such as may
be installed on floating roof tanks, the angle of which changes with the rise and fall of the base
Where are fixed stairs required?
Fixed Industrial Stairs shall be provided for access to and from places of work where operations
necessitate regular travel between levels. OSHA requirements include:
Fixed industrial stairs shall be strong enough to carry five times the normal anticipated live
At the very minimum, any fixed stairway shall be able to carry safely a moving
concentrated load of 1000 pounds.
All fixed stairways shall have a minimum width of 22 inches.
Fixed stairs shall be installed at angles to the horizontal of between 30 and 50 degrees.
Vertical clearances above any stair tread to an overhead obstruction shall be at least 7 feet
measured from the leading edge of the tread.
When inspecting the condition of stairways in your place of work, here are some items to check:
Handrails and Stair rails:
A. Lack of
B. Placement
C. Smoothness of surface
D. Strength
E. Clearance between rail and wall or other object
A. Strength
B. Slip resistance
C. Dimensions
D. Evenness of surface
E. Visibility of leading edge
Improper/inadequate design, construction or location of staircases.
Wet, slippery, or damaged walking or grasping surfaces.
Improper illumination: There is no general OSHA standard for illumination levels.
Consult with The Illuminating Engineering Society publications for recommendations.
Poor housekeeping: Cleanliness is imperative to prevent tripping and falls.
Landings: The length of a staircase is important. Long flights of steps without landings
should be avoided. The OSHA standards do not specify any exact number or placement of
landings. The National Safety Council recommends landings every tenth or twelfth tread.
Intermediate landings and platforms on stairways shall be no less than the stair width and a
minimum of 30 inches in length measured in the direction of travel.
A ladder is an appliance consisting of two side rails joined at regular intervals by crosspieces on
which a person may step to ascend or descend. The chief hazard when using a ladder is falling. A
poorly designed, maintained, or improperly used ladder may collapse under the load placed upon it
and cause the employee to fall. The various types of portable ladders include:
Stepladder - A self-supporting portable ladder, non-adjustable in length, having flat steps
and hinged back.
Single Ladder - A non self-supporting portable ladder, nonadjustable in length, consisting
of but one section. Its size is designed by overall length of the side rail.
Extension Ladder - A non self-supporting portable ladder adjustable in length.
OSHA's requirements for portable ladders include:
Portable stepladders longer than 20 feet shall not be used.
Stepladders shall be equipped with a metal spreader or locking device of sufficient size and
strength to securely hold the front and back sections in open position.
Single ladders longer than 30 feet shall not be used.
Extension ladders longer than 60 feet shall not be used.
Ladders shall be maintained in good condition at all times.
Ladders shall be inspected frequently and unsafe ladders shall be withdrawn from service
for repair or destruction and tagged or marked as "Dangerous, Do Not Use."
Proper use of ladders is essential in preventing accidents. Even a good ladder can be a serious
safety hazard when used by workers in a dangerous way.
OSHA standards require the following safety precautions for ladder use:
Ladders shall be placed with a secure footing, or they shall be lashed, or held in position.
Ladders used to gain access to a roof or other area shall extend at least 3 feet above the
point of support.
The foot of a ladder shall, where possible, be used at such a pitch that the horizontal
distance from the top support to the foot of the ladder is one-quarter of the working length
of the ladder (the length along the ladder between the foot and the support).
The worker shall always face the ladder when climbing up or down.
Short ladders shall not be spliced together to make long ladders.
Ladders shall never be used in the horizontal position as scaffolds or work platforms.
The top of a regular stepladder shall not be used as a step.
Use both hands when climbing or descending ladders.
Metal ladders shall never be used near electrical equipment.
Fixed ladder. A fixed ladder is a ladder permanently attached to a structure, building or equipment.
Fixed ladders of more than 20 feet to a maximum unbroken length of 30 feet shall be
equipped with cages or a ladder safety device.
Cage. A "cage" is a guard that is fastened to the side rails of the fixed ladder or to the structure to
encircle the climbing space of the ladder for the safety of the person who must climb the ladder.
Cages shall extend a minimum of 42 inches above the top of a landing, unless other
acceptable protection is provided.
Cages shall extend down the ladder to a point not less than 7 feet nor more than 8 feet
above the base of the ladder.
Ladder safety device. A ladder safety device is any device, other than a cage or well, designed to
eliminate or reduce the possibility of accidental falls and may incorporate such features as life
belts, friction brakes, and sliding attachments. Another feature of fixed ladders is the landing
platform, which provides a means of interrupting a free fall, and serves as a resting place during
long climbs.
When fixed ladders are used to ascend to heights exceeding 20 feet (except on chimneys), landing
platforms shall be provided for each 30 feet of height or fraction thereof, when cages are used,
except that, where no cage, well, or ladder safety device is provided, landing platforms shall be
provided for each 20 feet of height or fraction thereof.
Ladder safety devices may be used on tower, water tank, and chimney ladders over 20 feet in
unbroken length in lieu of cage protection. No landing platform is required in these cases.
The preferred pitch of fixed ladders shall be considered to come in the range of 75 degrees and 90
degrees with the horizontal. Fixed ladders shall be considered to be substandard if they are installed
within the pitch range of 60 and 75 degrees with the horizontal. Substandard fixed ladders are
permitted only where it is found necessary to meet conditions of installation. This substandard
pitch range shall be considered as a critical range to be avoided, if possible. Ladders having a pitch
in excess of 90 degrees with the horizontal are prohibited.
As with all ladders, fixed ladders shall be maintained in a safe condition and inspected regularly.
An important requirement, which can prevent many serious accidents is contained in this section:
portable dockboards (bridge plates) shall be secured in position, either by being anchored or
equipped with devices which will prevent their slipping. Movement of the dockboard during
material handling operations has resulted in forklifts overturning or falling off the dock, often with
serious injury or death to the driver and damage to equipment and material.
Another major contribution to accident experience comes from material handling. Handholds shall
be provided on portable dockboards to permit safe handling when the dockboard must be
repositioned or relocated.
Electricity has become an essential of modern life, both at home and on the job. Some employees
work with electricity directly, as is the case with engineers, electricians, or people who do wiring,
such as overhead lines, cable harnesses, or circuit assemblies. Others, such as office workers and
salespeople, work with it indirectly. As a source of power, electricity is accepted without much
thought to the hazards encountered. Perhaps because it has become such a familiar part of our
surroundings, it often is not treated with the respect it deserves.
OSHA's electrical standards address the government's concern that electricity has long been
recognized as a serious workplace hazard, exposing employees to such dangers as electric shock,
electrocution, fires and explosions. The objective of the standards is to minimize such potential
hazards by specifying design characteristics of safety in use of electrical equipment and systems.
OSHA's electrical standards were carefully developed to cover only those parts of any electrical
system that an employee would normally use or contact. The exposed and/or operating elements of
an electrical installation - lighting equipment, motors, machines, appliances, switches, controls,
enclosures, etc. - must be so constructed and installed as to minimize electrical dangers to people in
any workplace.
The OSHA electrical standards were based on the National Fire Protection Association's standard
NFPA 70E, Electrical Safety Requirements for Employee Workplaces, and the NFPA 70
Committee derived Part I of their document from the 1978 edition of the National Electrical Code
(NEC). The standards extracted from the NEC were those considered to most directly apply to
employee safety and least likely to change with each new edition of the NEC. OSHA's electrical
standards are performance oriented; therefore they contain few direct references to the NEC.
However, the NEC contains specific information as to how the required performance can be
Electrical equipment shall be free from recognized hazards that are likely to cause death or serious
physical harm to employees. (1) Safety of equipment shall be determined using the following
Suitability for installation and use in conformity with the provisions of this subpart.
Suitability of equipment for an identified purpose may be evidenced by listing or labeling
for that identified purpose.
Mechanical strength and durability, including, for parts designed to enclose and protect
other equipment, the adequacy of the protection thus provided.
Electrical insulation.
Heating effects under conditions of use.
Arcing effects.
Classification by type, size, voltage, current capacity, and specific use.
Other factors which contribute to the practical safeguarding of employees using or likely to
come in contact with the equipment.
Note: This requirement is, in effect, an electrical "general duty clause" similar to Section 5(a)(1) of
the OSH Act: "each employer shall furnish . . . a place of employment which is free from
recognized hazards that are causing or are likely to cause death or serious harm to his employees."
Listed or labeled equipment shall be used or installed in accordance with any instructions included
in the listing or labeling.
Disconnecting means. A disconnecting means is a switch that is used to disconnect the conductors
of a circuit from the source of electric current. Disconnect switches are important because they
enable a circuit to be opened, stopping the flow of electricity, and thus can effectively protect
workers and equipment.
Each disconnecting means required by this subpart for motors and appliances shall be legibly
marked to indicate its purpose, unless located and arranged so the purpose is evident. Each service,
feeder, and branch circuit, at its disconnecting means or over current device, shall be legibly
marked to indicate its purpose, unless located and arranged so the purpose is evident. These
markings shall be of sufficient durability to withstand the environment involved.
Each disconnect switch or over current device required for a service, feeder, or branch circuit must
be clearly labeled to indicate the circuit's function, and the label or marking should be located at the
point where the circuit originates. For example, on a panel that controls several motors or on a
motor control center, each disconnect must be clearly marked to indicate the motor to which each
circuit is connected. In the figure below, the Number 2 circuit breaker in the panel box supplies
current only to disconnect Number 2, which in turn controls the current to motor Number 2. This
current to motor Number 2 can be shut off by the Number 2 circuit breaker or the Number 2
If the purpose of the circuit is obvious, no identification of the disconnect is required. Each
Disconnect and Circuit Requires Identification
All labels and markings must be durable enough to withstand weather, chemicals, heat, corrosion,
or any other environment to which they may be exposed.
Note that this particular section is concerned with the safety of a person qualified to work on the
equipment. The hazard must be treated in a different way if the person will remove guards and
enclosures and actually work on the live parts. Sufficient access and working space shall be
provided and maintained about all electric equipment to permit ready and safe operation and
maintenance of such equipment.
Working space required by this subpart may not be used for storage. When normally enclosed live
parts are exposed for inspection or servicing, the working space, if in a passageway or general open
space, shall be suitably guarded.
It should be noted that the purpose of this requirement is to protect any person who may be in the
vicinity of electrical equipment against accidental contact. These people are presumably not
electricians working on the equipment, and are not qualified or trained to be in close proximity to
live parts.
Except as required or permitted elsewhere in this subpart, live parts of electric equipment operating
at 50 volts or more shall be guarded against accidental contact by approved cabinets or other forms
of approved enclosures, or by any of the following means:
By location in a room, vault, or similar enclosure that is accessible only to qualified persons.
By suitable permanent, substantial partitions or screens so arranged that only qualified persons will
have access to the space within reach of the live parts. Any openings in such partitions or screens
shall be so sized and located that persons are not likely to come into accidental contact with the live
parts or to bring conducting objects into contact with them. It is good practice to use covers,
screens or partitions, which can only be removed by, use of tools, so that unqualified persons are
less likely to violate them.
By location on a suitable balcony, gallery, or platform.
By elevation of 8 feet or more above the floor or other working surface. Note that, although
equipment elevated at least 8 feet is considered to be guarded, this may not be adequate if material
being handled is likely to make contact with live parts.
Where electric equipment would be exposed to physical damage, enclosures or guards shall be so
arranged and of such strength as to prevent such damage. Entrances to rooms and other guarded
locations containing exposed live parts shall be marked with conspicuous warning signs forbidding
unqualified persons to enter.
You should be constantly aware of hazards in your workplace. New work or changes may create a
new hazard, or poor maintenance may allow reappearance of old ones.
A conductor used as a grounded conductor shall be identifiable and distinguishable from all other
conductors. A conductor used as an equipment-grounding conductor shall be identifiable and
distinguishable from all other conductors.
The grounded conductor is an energized circuit conductor that is connected to earth through the
system ground. It is commonly referred to as the neutral. The equipment-grounding conductor is
not an energized conductor under normal conditions. The equipment grounding conductor acts as a
safeguard against insulation failure or faults in the other circuit conductors. The equipmentgrounding conductor is energized only if there is a leak or fault in the normal current path, and it
directs this current back to the source. Directing the fault current back to the source enables
protective devices, such as circuit breakers or fuses, to operate thus preventing fires and reducing
the hazard of electrical shocks.
The grounded and equipment grounding conductors of an electrical circuit must be marked or color
coded in a way that allows employees to identify them and tell them apart from each other and
from the other conductors in the circuit.
No grounded conductor may be attached to any terminal or lead so as to reverse designated
A grounding terminal or grounding-type device on a receptacle, cord connector, or attachment plug
may not be used for purposes other than grounding.
The above two subparagraphs dealing with polarity of connections and use of grounding terminals
and devices address one potentially dangerous aspect of alternating current: many pieces of
equipment will operate properly even though the supply wires are not connected in the order
designated by design or the manufacturer. Improper connection of these conductors is most
prevalent on the smaller branch circuit typically associated with standard 120 volt receptacle
outlets, lighting fixtures and cord- and plug-connected equipment.
When plugs, receptacles, and connectors are used in an electrical branch circuit, correct polarity
between the ungrounded (hot) conductor, the grounded (neutral) conductor, and the grounding
conductor must be maintained.
Reversed polarity is a condition when the identified circuit conductor (the grounded conductor or
neutral) is incorrectly connected to the ungrounded or "hot" terminal of a plug, receptacle, or other
type of connector.
This section contains grounding requirements for systems, circuits, and equipment. Grounding
electrical circuits and electrical equipment is required to protect employees against electrical shock,
safeguard against fire, and protect against damage to electrical equipment. There are two
kinds of grounding: (1) electrical circuit or system grounding, and (2) electrical equipment
grounding. Electrical system grounding is accomplished when one conductor of the circuit is
intentionally connected to earth. This is done to protect the circuit should lightning strike or other
high voltage contact occur. Grounding a system also stabilizes the voltage in the system so
"expected voltage levels" are not exceeded under normal conditions.
The second kind of ground is equipment grounding. This is accomplished when all metal frames of
equipment and enclosures containing electrical equipment or conductors are grounded by means of
a permanent and continuous connection or bond. The equipment grounding conductor provides a
path for dangerous fault current to return to the system ground at the supply source of the circuit
should an insulation failure takes place. If installed properly, the equipment-grounding conductor is
the current path that enables protective devices, such as circuit breakers and fuses, to operate when
a fault occurs.
Flexible cords shall be used only in continuous lengths without splice or tap. Hard service flexible
cords, No. 12 or larger, may be repaired if spliced so that the splice retains the insulation, outer
sheath properties, and usage characteristics of the cord being spliced.
Flexible cords shall be connected to devices and fittings so that strain relief is provided which will
prevent pull from being directly transmitted to joints or terminal screws.
The hazards encountered and associated with entering and working in confined spaces are capable
of causing bodily injury, illness, and death to the worker. Accidents occur among workers because
of failure to recognize that a confined space is a potential hazard. It should therefore be considered
that the most unfavorable situation exists in every case and that the danger of explosion, poisoning,
and asphyxiation will be present at the onset of entry.
Before forced ventilation is initiated, information such as restricted areas within the confined space,
voids, the nature of the contaminants present, the size of the space, the type of work to be
performed, and the number of people involved should be considered. The ventilation air should not
create an additional hazard due to re-circulation of contaminants, improper arrangement of the inlet
duct, or by the substitution of anything other than fresh (normal) air (approximately 20.9% oxygen,
78.1% nitrogen, and 1% argon with small amounts of various other gases). The terms air and
oxygen are sometimes considered synonymous. However, this is a dangerous assumption, since the
use of oxygen in place of fresh (normal) air for ventilation will expand the limits of flammability
and increase the hazards of fire and explosion.
Hazardous conditions covered in this discussion include: Hazardous Atmospheres (flammable,
toxic, irritant, and asphyxiating), and General Safety Hazards (mechanical, communications, entry
and exit, and physical).
Confined spaces can be categorized generally as those with open tops and with a depth that will
restrict the natural movement of air, and enclosed spaces with very limited openings for entry. In
either of these cases, the space may contain mechanical equipment with moving parts. Any
combination of these parameters will change the nature of the hazards encountered. Degreasers,
pits, and certain types of storage tanks may be classified as open topped confined spaces that
usually contain no moving parts. However, gases that are heavier than air (butane, propane, and
other hydrocarbons) remain in depressions and will flow to low points where they are difficult
to remove. Open topped water tanks that appear harmless may develop toxic atmospheres such as
hydrogen sulfide from the vaporization of contaminated water. Therefore, these gases (heavier than
air) are a primary concern when entry into such a confined space is being planned. Other hazards
may develop due to the work performed in the confined space or because of corrosive residues that
accelerate the decomposition of scaffolding supports and electrical components.
Confined spaces such as sewers, casings, tanks, silos, vaults, and compartments of ships usually
have limited access. The problems arising in these areas are similar to those that occur in open
topped confined spaces. However, the limited access increases the risk of injury. Gases that are
heavier than air such as carbon dioxide and propane, may lie in a tank or vault for hours or even
days after the containers have been opened. Because some gases are odorless, the hazard may be
overlooked with fatal results. Gases that are lighter then air may also be trapped within an enclosed
type confined space, especially those with access from the bottom or side.
Hazards specific to a confined space are dictated by: (1) the material stored or used in the confined
space; as an example, damp activated carbon in a filtration tank will absorb oxygen, thus creating
an oxygen deficient atmosphere; (2) the activity carried out, such as the fermentation of molasses
that creates ethyl alcohol vapors and decreases the oxygen content of the atmosphere; or (3) the
external environment, as in the case of sewer systems that may be affected by high tides, heavier
than air gases, or flash floods.
The most hazardous kind of confined space is the type that combines limited access and
mechanical devices. All the hazards of open top and limited access confined spaces may be present
together with the additional hazard of moving parts. Digesters and boilers usually contain powerdriven equipment, which, unless properly isolated, may be inadvertently activated after entry. Such
equipment may also contain physical hazards that further complicate the work environment and the
entry and exit process.
Entering a confined space as part of the industrial activity may be done for various reasons. It is
done usually to perform a necessary function, such as inspection, repair, maintenance (cleaning or
painting), or similar operations, which would be an infrequent or irregular function of the total
industrial activity.
Entry may also be made during new construction. Potential hazards should be easier to recognize
during construction since the confined space has not been used. The types of hazards involved will
be limited by the specific work practices. When the area meets the criteria for a confined space, all
ventilation and other requirements should be enforced.
One of the most difficult entries to control is that of unauthorized entry, especially when there are
large numbers of workers and trades involved, such as welders, painters, electricians, and safety
A final and most important reason for entry would be emergency rescue. This, and all other
reasons for entry, must be well planned before initial entry is made and the hazards must be
thoroughly reviewed. The standby person and all rescue personnel should be aware of the structural
design of the space, emergency exit procedures, and life support systems required.
Hazardous atmospheres encountered in confined spaces can be divided into four distinct categories:
Flammable, Toxic, Irritant and/or Corrosive, and Asphyxiating.
Flammable Atmospheres
A flammable atmosphere generally arises from enriched oxygen atmospheres, vaporization of
flammable liquids, byproducts of work, chemical reactions, concentrations of combustible dusts,
and desorption of chemical from inner surfaces of the confined space.
An atmosphere becomes flammable when the ratio of oxygen to combustible material in the air is
neither too rich nor too lean for combustion to occur. Combustible gases or vapors will accumulate
when there is inadequate ventilation in areas such as a confined space. Flammable gases such as
acetylene, butane, propane, hydrogen, methane, natural or manufactured gases or vapors from
liquid hydrocarbons can be trapped in confined spaces, and since many gases are heavier than air,
they will seek lower levels as in pits, sewers, and various types of storage tanks and vessels. In a
closed top tank, it should also be noted that lighter than air gases may rise and develop a flammable
concentration if trapped above the opening.
The byproducts of work procedures can generate flammable or explosive conditions within a
confined space. Specific kinds of work such as spray painting can result in the release of explosive
gases or vapors. Welding in a confined space is a major cause of explosions in areas that contain
combustible gas.
Chemical reactions forming flammable atmospheres occur when surfaces are initially exposed to
the atmosphere, or when chemicals combine to form flammable gases. This condition arises when
dilute sulfuric acid reacts with iron to form hydrogen or when calcium carbide makes contact with
water to form acetylene. Other examples of spontaneous chemical reactions that may produce
explosions from small amounts of unstable compounds are acetylene-metal compounds, peroxides,
and nitrates. In a dry state, these compounds have the potential to explode upon percussion or
exposure to increased temperature. Another class of chemical reactions that form flammable
atmospheres arises from deposits of pyrophoric substances (carbon, ferrous oxide, ferrous sulfate,
iron, etc.) that can be found in tanks used by the chemical and petroleum industry. These tanks
containing flammable deposits will spontaneously ignite upon exposure to air.
Combustible dust concentrations are usually found during the process of loading, unloading, and
conveying grain products, nitrated fertilizers, finely ground chemical products, and any other
combustible material. High charges of static electricity, which rapidly accumulate during periods of
relatively low humidity (below 50%), can cause certain substances to accumulate electrostatic
charges of sufficient energy to produce sparks and ignite a flammable atmosphere. These sparks
may also cause explosions when the right air or oxygen to dust or gas mixture is present.
Toxic Atmospheres
The substances to be regarded as toxic in a confined space can cover the entire spectrum of gases,
vapors, and finely divided airborne dust in industry. The sources of toxic atmospheres encountered
may arise from the following:
1. The manufacturing process (for example, in producing polyvinyl chloride, hydrogen chloride is
used as will as vinyl chloride monomer, which is carcinogenic).
2. The product stored [removing decomposed organic material from a tank can liberate toxic
substances, such as hydrogen sulfide (H2S)].
3. The operation performed in the confined space (for example, welding or brazing with metals
capable of producing toxic fumes).
During loading, unloading, formulation, and production, mechanical and/or human error may also
produce toxic gases that are not part of the planned operation.
Carbon monoxide (CO) is a hazardous gas that may build up in a confined space. This odorless,
colorless gas that has approximately the same density as air is formed from incomplete combustion
of organic materials such as wood, coal, gas, oil, and gasoline; it can be formed from microbial
decomposition of organic matter in sewers, silos, and fermentation tanks. Carbon monoxide is an
insidious toxic gas because of its poor warning properties. Early stages of CO intoxication are
nausea and headache. Carbon monoxide may be fatal at 1000 ppm in air, and is considered
dangerous at 200 ppm, because it forms carboxyhemoglobin in the blood, which prevents the
distribution of oxygen in the body.
Carbon monoxide is a relatively abundant colorless, odorless gas, therefore, any untested
atmosphere must be suspect. It must also be noted that a safe reading on a combustible gas
indicator does not ensure that CO is not present. Carbon monoxide must be tested for specifically.
The formation of CO may result from chemical reactions or work activities, therefore fatalities due
to CO poisoning are not confined to any particular industry. There have been fatal accidents in
sewage treatment plants due to decomposition products and lack of ventilation in confined spaces.
Another area where CO results as a product of decomposition is in the formation of silo gas in
grain storage elevators. In another area, the paint industry, varnish is manufactured by introducing
the various ingredients into a kettle, and heating them in an inert atmosphere, usually town gas,
which is a mixture of carbon dioxide and nitrogen.
In welding operations, oxides of nitrogen and ozone are gases of major toxicological importance,
and incomplete oxidation may occur and carbon monoxide can form as a byproduct.
Another poor work practice, which has led to fatalities, is the recirculation of diesel exhaust
emissions. Increased CO levels can be prevented by strict control of the ventilation and the use of
catalytic converters.
Irritant and/or Corrosive Atmospheres
Irritant or corrosive atmospheres can be divided into primary and secondary groups. The primary
irritants exert no systemic toxic effects (effects on the entire body). Examples of primary irritants
are chlorine, ozone, hydrochloric acid, hydrofluoric acid, sulfuric acid, nitrogen dioxide, ammonia,
and sulfur dioxide. A secondary irritant is one that may produce systemic toxic effects in addition
to surface irritation. Examples of secondary irritants include benzene, carbon tetrachloride, ethyl
chloride, trichloroethane, trichloroethylene, and chloropropene.
Irritant gases vary widely among all areas of industrial activity. They can be found in plastics
plants, chemical plants, the petroleum industry, tanneries, refrigeration industries, paint
manufacturing, and mining operations.
Prolonged exposure at irritant or corrosive concentrations in a confined space may produce little or
no evidence of irritation. This may result in a general weakening of the defense reflexes from
changes in sensitivity. The danger in this situation is that the worker is usually not aware of any
increase in his/her exposure to toxic substances.
Asphyxiating Atmospheres
The normal atmosphere is composed approximately of 20.9% oxygen and 78.1% nitrogen, and 1%
argon with small amounts of various other gases. Reduction of oxygen in a confined space may be
the result of either consumption or displacement.
The consumption of oxygen takes place during combustion of flammable substances, as in welding,
heating, cutting, and brazing. A more subtle consumption of oxygen occurs during bacterial action,
as in the fermentation process. Oxygen may also be consumed during chemical reactions as in the
formation of rust on the exposed surface of the confined space (iron oxide). The number of people
working in a confined space and the amount of their physical activity will also influence the
consumption rate.
A second factor in oxygen deficiency is displacement by another gas. Examples of gases that are
used to displace air, and therefore reduce the oxygen level are helium, argon, and nitrogen. Carbon
dioxide may also be used to displace air and can occur naturally in sewers, storage bins, wells,
tunnels, wine vats, and grain elevators. Aside from the natural development of these gases, or their
use in the chemical process, certain gases are also used as inerting agents to displace flammable
substances and retard pyrophoric reactions. Gases such as nitrogen, argon, helium, and carbon
dioxide, are frequently referred to as non-toxic inert gases but have claimed many lives. The use of
nitrogen to inert a confined space has claimed more lives than carbon dioxide. The total
displacement of oxygen by nitrogen will cause immediate collapse and death. Carbon dioxide and
argon, with specific gravities greater than air, may lie in a tank or manhole for hours or days after
opening. Since these gases are colorless and odorless, they pose an immediate hazard to health
unless appropriate oxygen measurements and ventilation are adequately carried out.
Oxygen deprivation is one form of asphyxiation. While it is desirable to maintain the atmospheric
oxygen level at 21% by volume, the body can tolerate deviation from this ideal. When the oxygen
level falls to 17%, the first sign of hypoxia is a deterioration to night vision, which is not noticeable
until a normal oxygen concentration is restored. Physiologic effects are increased breathing volume
and accelerated heartbeat. Between 14-16% physiologic effects are increased breathing volume,
accelerated heartbeat, very poor muscular coordination, rapid fatigue, and intermittent respiration.
Between 6-10% the effects are nausea, vomiting, inability to perform, and unconsciousness. Less
than 6%, spasmatic breathing, convulsive movements, and death in minutes.
General safety hazards may be classified as Mechanical Hazards, Communication Problems, Entry
and Exit, Physical Hazards (thermal, noise, vibration, exposures, and structural).
Mechanical Hazards
If activation of electrical or mechanical equipment would cause injury, each piece of equipment
should be manually isolated to prevent inadvertent activation before workers enter or while they
work in a confined space. The interplay of hazards associated with a confined space, such as the
potential of flammable vapors or gases being present, and the build-up of static charge due to
mechanical cleaning, such as abrasive blasting, all influence the precautions, which must be taken.
To prevent vapor leaks, flashbacks, and other hazards, workers should completely isolate the space.
To completely isolate a confined space, the closing of valves is not sufficient. All pipes must be
physically disconnected or isolation blanks bolted in place. Other special precautions must be taken
in cases where flammable liquids or vapors may re-contaminate the confined space. The pipes
blanked or disconnected should be inspected and tested for leakage to check the effectiveness of the
procedure. Other areas of concern are steam valves, pressure lines, and chemical transfer pipes. A
less apparent hazard is the space referred to as a void, such as double walled vessels, which must be
given special consideration in blanking off and inerting.
Communication Problems
Communication between the worker inside and the standby person outside is of utmost importance.
If the worker should suddenly feel distressed and not be able to summon help, an injury could
become a fatality. Frequently, the body positions that are assumed in a confined space make it
difficult for the standby person to detect an unconscious worker. When visual monitoring of the
worker is not possible because of the design of the confined space or location of the entry hatch, a
voice or alarm-activated explosion proof type of communication system will be necessary.
Suitable illumination of an approved type is required to provide sufficient visibility for work in
accordance with the recommendations made in the Illuminating Engineering Society Lighting
Entry and Exit
Entry and exit time is of major significance as a physical limitation and is directly related to the
potential hazard of the confined space. The extent of precautions taken and the standby equipment
needed to maintain a safe work area will be determined by the means of access and rescue. The
following should be considered: type of confined space to be entered, access to the entrance,
number and size of openings, barriers within the space, the occupancy load, and the time
requirement for exiting in event of fire or vapor incursion, and the time required to rescue injured
Physical Hazard: Thermal Effects
Four factors influence the interchange of heat between people and their environment. They are: (1)
air temperature, (2) air velocity, (3) moisture contained in the air, and (4) radiant heat. Because of
the nature and design of most confined spaces, moisture content and radiant heat are difficult to
control. As the body temperature rises progressively, workers will continue to function until the
body temperature reaches approximately 102oF. When this body temperature is exceeded, the
workers are less efficient, and are prone to heat exhaustion, heat cramps, or heat stroke. In a cold
environment, certain physiologic mechanisms come into play, which tend to limit heat loss and
increase heat production. The most severe strain in cold conditions is chilling of the extremities so
that activity is restricted. Special precautions must be taken in cold environments to prevent
frostbite, trench foot, and general hypothermia.
Protective insulated clothing for both hot and cold environments will add additional bulk to the
worker and must be considered in allowing for movement in the confined space and exit time.
Therefore, air temperature of the environment becomes an important consideration when evaluating
working conditions in confined spaces.
Physical Hazard: Noise
Noise problems are usually intensified in confined spaces because the interior tends to cause sound
to reverberate and thus expose the worker to higher sound levels than those found in an open
environment. This intensified noise increases the risk of hearing damage to workers, which could
result in temporary or permanent loss of hearing. Noise in a confined space, which may not be
intense enough to cause hearing damage, may still disrupt verbal communication with the
emergency standby person on the exterior of the confined space. If the workers inside are not able
to hear commands or danger signals due to excessive noise, the probability of severe accidents can
Physical Hazard: Vibration
Whole body vibration may affect multiple body parts and organs depending upon the vibration
characteristics. Segmental vibration, unlike whole body vibration, appears to be more localized in
creating injury to the fingers and hands of workers using tools, such as pneumatic hammers, rotary
grinders or other hand tools which cause vibration.
Physical Hazard: Exposure
Surface residues in confined spaces can increase the already hazardous conditions of electrical
shock, reaction of incompatible materials, liberation of toxic substances, and bodily injury due to
slips and falls. Without protective clothing, additional hazards to health may arise due to surface
Physical Hazard: Structural Challenges
Some physical hazards cannot be eliminated because of the nature of the confined space or the
work to be performed. These hazards include such items as scaffolding, surface residues, and
structural hazards. The use of scaffolding in confined spaces has contributed to many accidents
caused by workers or materials falling, improper use of guard rails, and lack of maintenance to
insure worker safety. The choice of material used for scaffolding depends upon the type of work to
be performed, the calculated weight to be supported, the surface on which the scaffolding is placed,
and the substance previously stored in the confined spaces. Structural hazards within a confined
space such as baffles in horizontal tanks, trays in vertical towers, bends in tunnels, overhead
structural members, or scaffolding installed for maintenance constitute physical hazards, which are
exacerbated by the physical surroundings. In dealing with structural hazards, workers must review
and enforce safety precautions to assure safety.
Rescue procedures may require withdrawal of an injured or unconscious person. Careful planning
must be given to the relationship between the internal structure, the exit opening, and the worker. If
the worker is above the opening, the system must include a rescue arrangement operated from
outside the confined space, if possible, by which the employee can be lowered and removed
without injury.
Many workplaces contain spaces that are considered to be "confined" because their configurations
hinder the activities of any employees who must enter into, work in, and exit from them. In many
instances, employees who work in confined spaces also face increased risk of exposure to serious
physical injury from hazards such as entrapment, engulfment, and hazardous atmospheric
conditions. Confinement itself may pose entrapment hazards, and work in confined spaces may
keep employees closer to hazards, such as an asphyxiating atmosphere, than they would be
otherwise. For example, confinement, limited access, and restricted airflow can result in hazardous
conditions that would not arise in an open workplace.
The term "permit-required confined space" (i.e., permit space) refers to those spaces that meet the
definition of a "confined space" and pose health or safety hazards, thereby requiring a permit for
A confined space has limited or restricted means of entry or exit, is large enough for an employee
to enter and perform assigned work, and is not designed for continuous occupancy by the
employee. These spaces may include, but are not limited to, underground vaults, tanks, storage
bins, pits and dikes, vessels, and silos.
A permit-required confined space is one that meets the definition of a confined space and has one
or more of these characteristics: (1) contains or has the potential to contain a hazardous
atmosphere, (2) contains a material that has the potential for engulfing an entrant, (3) has an
internal configuration that might cause an entrant to be trapped or asphyxiated by inwardly
converging walls or by a floor that slopes downward and tapers to a smaller cross section, and/or
(4) contains any other recognized serious safety or health hazards.
In general, employers must evaluate the workplace to determine if spaces are permit-required
confined spaces. (See flow chart). If there are permit spaces in the workplace, the employer must
inform exposed employees of the existence, location, and danger posed by the spaces. This can be
accomplished by posting danger signs or by another equally effective means. The following
language would satisfy the requirements for such a sign:
If employees are not to enter and work in permit spaces, employers must take effective measures to
prevent their employees from entering the permit spaces.
If employees are to enter permit spaces, the employer must develop a written permit space
program, which shall be made available to employees or their representatives. Under certain
conditions, the employer may use alternate procedures for worker entry into a permit space. For
example, if employers can demonstrate with monitoring and inspection data that the only hazard is
an actual or potential hazardous atmosphere, which can be made safe for entry by the use of
continuous forced air ventilation alone, they may be exempted from some requirements, such as
permits and attendants. Even in such circumstances, however, the internal atmosphere of the space
must be tested first for oxygen content, second for flammable gases and vapors, and third for
potential toxic air contaminants before any employee enters.
Written Program
Employers who allows employee entry must develop and implement a written program for permitrequired confined spaces.
Among other things, the OSHA standard requires the employer's program to:
Identify and evaluate permit space hazards before allowing employee entry;
Test conditions in the permit space before entry and monitor the space during entry;
Perform in the following sequence, appropriate testing for atmospheric hazards: oxygen,
combustible gases or vapors, and toxic gases or vapors;
Implement necessary measures to prevent unauthorized entry;
Establish and implement the means, procedures and practices--such as specifying
acceptable entry conditions, isolating the permit space, providing barriers, verifying
acceptable entry conditions, purging, making inert, flushing, or ventilation of the permit
space—to eliminate or control hazards necessary for safe permit-space entry operations;
Identify employee job duties;
Provide, maintain, and require, at no cost to the employee, the use of personal protective
equipment and any other equipment necessary for safe entry (e.g., testing, monitoring,
ventilating, communications, and lighting equipment; barriers, shields, and ladders);
Ensure that at least one attendant is stationed outside the permit space for the duration of
entry operations;
Coordinate entry operations when employees of more than one employer are to be working
in the permit space;
Implement appropriate procedures for summoning rescue and emergency services;
Establish, in writing, and implement a system for the preparation, issuance, use, and
cancellation of entry permits;
Review established entry operations and annually revise the permit-space entry program;
When an attendant is required to monitor multiple spaces, implement the procedures to be
followed during an emergency in one or more of the permit spaces being monitored.
If hazardous conditions are detected during entry, employees must immediately leave the space,
and the employer must evaluate the space to determine the cause of the hazardous atmospheres.
When entry to permit spaces is prohibited, the employer must take effective measures to prevent
unauthorized entry. Non-permit confined spaces must be reevaluated when there are changes in
their use or configuration and, where appropriate, must be reclassified.
If testing and inspection data prove that a permit-required confined space no longer poses hazards,
that space may be reclassified as a non-permit confined space. If entry is required to eliminate
hazards and to obtain the data, the employer must follow procedures as set forth under sections (d)
through (k) of the standard. A certificate documenting the data must be made available to
employees entering the space. The certificate must include the date, location of the space, and the
signature of the person making the certification.
Contractors also must be informed of permit spaces and permit space entry requirements, any
identified hazards, the employer's experience with the space (i.e., the knowledge of hazardous
conditions), and precautions or procedures to be followed when in or near permit spaces.
When employees of more than one employer are conducting entry operations, the affected
employers must coordinate entry operations to ensure that affected employees are appropriately
protected from permit space hazards. Contractors also must be given and other pertinent
information regarding hazards and operations in permit spaces and are debriefed at the conclusion
of entry operations.
Permit System
A permit, signed by the entry supervisor and verifying that pre-entry preparations have been
completed and that the space is safe to enter, must be posted at entrances or otherwise made
available to entrants before they enter a permit space.
The duration of entry permits must not exceed the time required to complete an assignment. Also,
the entry supervisor must terminate entry and cancel permits when an assignment has been
completed or when new conditions exist. New conditions must be noted on the canceled permit
and used in revising the permit space program. The standard also requires the employer to keep
all canceled entry permits for at least 1 year.
Entry Permits
Entry permits must include the following information:
Test results;
Tester's initials or signature;
Name and signature of supervisor who authorizes entry;
Name of permit space to be entered, authorized entrant(s), eligible attendants, and
individual(s) authorized to be entry supervisor(s);
Purpose of entry and known space hazards;
Measures to be taken to isolate permit spaces and to eliminate or control space hazards,
i.e., locking out or tagging of equipment a procedures for purging, making inert, ventilating
and flushing permit spaces;
Name and telephone numbers of rescue and emergency services;
Date and authorized duration of entry;
Acceptable entry conditions;
Communication procedures and equipment to maintain contact during entry;
Additional permits(s), i.e. hot work, issued to authorize work in the permit space;
Special equipment and procedures, including ppe and alarm systems; and
Any other information needed to ensure employee safety.
Training and Education
Before initial work assignment begins, the employer must provide proper training for all workers
who are required to work in permit spaces. Upon completing this training, employers must ensure
that employees have acquired the understanding, knowledge, and skills necessary for the safe
performance of their duties. Additional training is required when (1) the job duties change, (2)
there is a change in the permit-space program or the permit space operation presents a new hazard,
and (3) when an employee's job performance shows deficiencies. Training also is required for
rescue team members, including cardiopulmonary resuscitation (CPR) and first-aid training (see
Emergencies). Employers must certify that training has been accomplished.
Upon completion of training, employees must receive a certificate of training that includes the
employee's name, signature or initials of trainer(s), and dates of training. The certification must be
made available for inspection by employees and their authorized representatives.
In addition, the employer also must ensure that employees are trained in their assigned duties.
Authorized Entrant's Duties
Know space hazards, including information on the mode of exposure (e.g., inhalation or
dermal absorption), signs or symptoms, and consequences of the exposure;
Use appropriate personal protective equipment properly (e.g., face and eye protection, and
other forms of barrier protection such as gloves, aprons, and coveralls);
As necessary, maintain communication (i.e., telephone, radio, visual observation) with
attendants to enable the attendant to monitor the entrant's status as well as to alert the
entrant to evacuate;
Exit from permit space as soon as possible when ordered by an authorized person, when
the entrant recognizes the warning signs or symptoms of exposure exist, when a prohibited
condition exists, or when an automatic alarm is activated; and
Alert the attendant when a prohibited condition exists or when warning signs or symptoms
of exposure exist.
Attendant's Duties
Remain outside permit space during entry operations unless relieved by another authorized
Perform no-entry rescues when specified by employer's rescue procedure;
Know existing and potential hazards, including information on the mode of exposure, signs
or symptoms, consequences of the exposure, and their physiological effects;
Maintain communication with and keep an accurate account of those workers entering the
permit-required space;
Order evacuation of the permit space when a prohibited condition exists, when a worker
shows signs of physiological effects of hazardous exposure, when an emergency outside
the confined space exists, and when the attendant cannot effectively and safely perform
required duties;
Summon rescue and other services during an emergency;
Ensure that unauthorized persons stay away from permit spaces or exit
they have entered the permit space;
Inform authorized entrants and entry supervisor of entry by unauthorized persons; and;
Perform no other duties that interfere with the attendant's primary duties.
immediately if
Entry Supervisor's Duties
Know space hazards including information on the mode of exposure, signs, or symptoms
and consequences of exposure;
Verify emergency plans and specified entry conditions such as permits, tests, procedures,
and equipment before allowing entry;
Terminate entry and cancel permits when entry operations are complete or if a new
condition exists;
Take appropriate measures to remove unauthorized entrants; and
Ensure that entry operations remain consistent with the entry permit
and that acceptable entry conditions are maintained.
Confined Space Emergencies
The standard requires the employer to ensure that rescue service personnel are provided with and
trained in the proper use of personal protective and rescue equipment, including respirators; trained
to perform assigned rescue duties; and have had authorized entrant's training. The standard also
requires that all rescuers be trained in first aid and CPR and, at a minimum, one rescue team
member be currently certified in first aid and in CPR. The employer also must ensure that practice
rescue exercises are performed yearly, and that rescue services are provided access to permit spaces
so that they can practice rescue operations. Rescuers also must be informed of the hazards of the
permit space.
When appropriate, authorized entrants who enter a permit space must wear a chest or full body
harness with a retrieval line attached to the center of their backs near shoulder level, or above their
heads. Wristlets may be used if the employer can demonstrate that the use of a chest or full body
harness is infeasible or creates a greater hazard. The employer must ensure that the other end of the
retrieval line is attached to a mechanical device or to a fixed point outside the permit space. A
mechanical device must be available to retrieve personnel from vertical type permit spaces more
than 5 feet deep.
In addition, if an injured entrant is exposed to a substance for which a Material Safety Data Sheet
(MSDS) or other similar written information is required to be kept at the worksite, that MSDS or
other written information must be made available to the medical facility treating the exposed
This standard helps safeguard employees from hazardous energy while they are performing service
or maintenance on machines and equipment. The standard identifies the practices and procedures
necessary to shut down and lock out or tag out machines and equipment, requires that employees
receive training in their role in the lockout/tagout program, and mandates that periodic inspections
be conducted to maintain or enhance the energy control program.
In the early 1970's, OSHA adopted various lockout-related provisions of the then existing national
consensus standards and Federal standards that were developed for specific types of equipment or
industries. When the existing standards require lockout, the new rule supplements these existing
standards(1) by requiring the development and utilization of written procedures, the training of
employees, and periodic inspections of the use of the procedures. OSHA has determined that
lockout is a more reliable means of de-energizing equipment than tagout and that it should always
be the preferred method used by employees. The Agency believes that, except for limited
situations, the use of lockout devices will provide a more secure and more effective means of
protecting employees from the unexpected release of hazardous energy or start-up of machines and
This rule requires that, in general, before service or maintenance is performed on machinery or
equipment, the machinery or equipment must be turned off and disconnected from the energy
source, and the energy-isolating device must be either locked or tagged out. OSHA estimates that
adherence to the requirements of this standard can eliminate nearly 2% of all workplace deaths in
establishments affected by this rule and can have a significant impact on worker safety and health
in the U.S.
Affected employee - An employee who performs the duties of his or her job in an area in which the
energy control procedure is implemented and servicing or maintenance operations are performed.
An affected employee does not perform servicing or maintenance on machines or equipment and,
consequently, is not responsible for implementing the energy control procedure. An affected
employee becomes an "authorized" employee whenever he or she performs servicing or
maintenance functions on machines or equipment that must be locked or tagged.
Authorized employee. An employee who performs servicing or maintenance on machines and
equipment. Lockout or tagout is used by these employees for their own protection.
Capable of being locked out An energy-isolating device is considered capable of being locked out
if it meets one of the following requirements:
It is designed with a hasp to which a lock can be attached;
It is designed with any other integral part through which a lock can be affixed;
It has a locking mechanism built into it; or
It can be locked without dismantling, rebuilding, or replacing the energy isolating device or
permanently altering its energy control capability.
Energized. Machines and equipment are energized when (1) they are connected to an energy
source or (2) they contain residual or stored energy.
Energy-isolating device. Any mechanical device that physically prevents the transmission or
release of energy. These include, but are not limited to, manually-operated electrical circuit
breakers, disconnect switches, line valves, and blocks.
Energy source. Any source of electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or
other energy.
Energy control procedure. A written document that contains those items of information an
authorized employee needs to know in order to safely control hazardous energy during servicing or
maintenance of machines or equipment.
Energy control program. A program intended to prevent the unexpected energizing or the release
of stored energy in machines or equipment on which servicing and maintenance is being performed
by employees. The program consists of energy control procedure(s), an employee training program,
and periodic inspections.
Lockout. The placement of a lockout device on an energy – isolating device, in accordance with an
established procedure, ensures that the energy - isolating device and the equipment being controlled
cannot be operated until the lockout device is removed.
Lockout device. Any device that uses positive means such as a lock, either key or combination
type, to hold an energy - isolating device in a safe position, thereby preventing the energizing of
machinery or equipment. When properly installed, a blank flange or bolted slip blind are
equivalent to lockout devices.
Tagout. The placement of a tagout device on an energy-isolating device, in accordance with an
established procedure, to indicate that the energy-isolating device and the equipment being
controlled may not be operated until the tagout device is removed.
Tagout device. Any prominent warning device, such as a tag and a means of attachment that can
be securely fastened to an energy - isolating device in accordance with an established procedure.
The tag indicates that the machine or equipment to which it is attached is not to be operated until
the tagout device is removed in accordance with the energy control procedure.
The lockout/tagout standard applies to general industry employment and covers the servicing and
maintenance of machines and equipment in which the unexpected start-up or the release of stored
energy could cause injury to employees. (If employees are performing service or maintenance tasks
that do not expose them to the unexpected release of hazardous energy, the standard does not
The standard establishes minimum performance requirements for the control of hazardous energy.
The standard does not apply in the following situations:
while servicing or maintaining cord and plug connected electrical equipment. (The hazards
must be controlled by unplugging the equipment from the energy source; the plug must be
under the exclusive control of the employee performing the service and/or maintenance.)
during hot tap operations that involve transmission and distribution systems for gas, steam,
water, or petroleum products when they are performed on pressurized pipelines; when
continuity of service is essential, and shutdown of the system is impractical; and
employees are provided with an alternative type of protection that is equally effective.
OSHA recognizes that machines and equipment present many hazardous situations during normal
production operations - i.e., whenever machines and equipment are used to perform their usual
production function. These production hazards are covered by rules in other General Industry
Standards, such as the requirements in Subpart O of Part 1910 for general machine guarding and
guarding power transmission apparatus (1910.212 and 1910.219). In certain circumstances,
however, some hazards encountered during normal production operations may be covered by the
lockout/tagout rule. The following paragraphs illustrate some of these instances.
Servicing and/or Maintenance Operations
If a servicing activity - such as lubricating, cleaning, or unjamming the production equipment takes place during production, the employee performing the servicing may be subjected to hazards
that are not encountered as part of the production operation itself. Workers engaged in these
operations are covered by lockout/tagout when any of the following conditions occurs:
The employee must either remove or bypass machine guards or other safety devices,
resulting in exposure to hazards at the point of operation;
The employee is required to place any part of his or her body in contact with the point of
operation of the operational machine or piece of equipment; or
The employee is required to place any part of his or her body into a danger zone associated
with a machine operating cycle.
In the above situations, the equipment must be de-energized and locks or tags must be applied to
the energy-isolation devices.
In addition, when normal servicing tasks - such as setting equipment up, and/or making significant
adjustments to machines - do not occur during normal production operations, employees
performing such tasks are required to lock out or tag out if they can be injured by unexpected
energization of the equipment.
OSHA also recognizes that some servicing operations must be performed with the power on.
Making many types of fine adjustments, such as centering the belt on conveyors, is one example.
Certain aspects of troubleshooting, such as identifying the source of the problem as well as
checking to ensure that it has been corrected, is another. OSHA requires the employer to provide
effective protection for employees performing such operations. Although, in these cases, a poweron condition is essential either to accomplish the particular type of servicing or to verify that it was
performed properly, lockout or tagout procedures are required when servicing or maintenance
occurs with the power off.
Minor Servicing Tasks
Employees performing minor tool changes and adjustments and/or other minor service activities
during normal production operations that are routine, repetitive, and integral to the use of the
production equipment are not covered by the lockout/tagout standard, provided the work is
performed using alternative measures that give effective protection.
The standard requires employers to establish procedures for isolating machines or equipment from
the input of energy and affixing appropriate locks or tags to energy-isolating devices to prevent any
unexpected energization, start-up, or release of stored energy that would injure workers. When tags
are used on energy-isolating devices capable of being locked out, the employer must provide
additional means to assure a level of protection equivalent to that of locks. The standard also
requires the training of employees, and periodic inspections of the procedures to maintain or
improve their effectiveness.
Energy Control Program
The lockout/tagout rule requires that the employer establish an energy control program that
includes (1) documented energy control procedures, (2) an employee training program, and (3)
periodic inspections of the procedures. The standard requires employers to establish a program to
ensure that machines and equipment are isolated and inoperative before any employee performs
service or maintenance where the unexpected energization, start up, or release of stored energy
could occur and cause injury.
The purpose of the energy control program is to ensure that, whenever the possibility of unexpected
machine or equipment start-up exists or when the unexpected release of stored energy could occur
and cause injury, the equipment is isolated from its energy source(s) and rendered inoperative prior
to servicing or maintenance.
Employers have the flexibility to develop a program and procedures that meet the needs of their
particular workplace and the particular types of machines and equipment being maintained or
Energy Control Procedure
This standard requires that energy control procedures be developed, documented, and used to
control potentially hazardous energy sources whenever workers perform activities covered by the
The written procedures must identify the information that authorized(2) employees must know in
order to control hazardous energy during service or maintenance. If this information is the same for
various machines or equipment or if other means of logical grouping exists, then a single energy
control procedure may be sufficient. If there are other conditions -such as multiple energy sources,
different connecting means, or a particular sequence that must be followed to shut down the
machine or equipment - then the employer must develop separate energy control procedures to
protect employees.
The energy control procedure must outline the scope, purpose, authorization, rules and techniques
that will be used to control hazardous energy sources as well as the means that will be used to
enforce compliance.
The written energy control procedure includes, but is not limited to, the following elements:
a statement on how the procedure will be used;
the procedural steps needed to shut down, isolate, block, and secure equipment;
the steps designating the safe placement, removal, and transfer of lockout/tagout devices
and who has the responsibility for them; and
the specific requirements for testing machines or equipment to determine and verify the
effectiveness of locks, tags, and other energy control measures.
The procedure must include the following steps: (1) preparing for shutdown, (2) shutting down the
machine(s) or equipment, (3) isolating the machine or equipment from the energy source(s), (4)
applying the lockout or tagout device(s) to the energy-isolating device(s), (5) safely releasing all
potentially hazardous stored or residual energy, and (6) verifying the isolation of the machine(s) or
equipment prior to the start of service or maintenance work.
In addition, before lockout or tagout devices are removed and energy is restored to the machines or
equipment, certain steps must be taken to re-energize equipment after service is completed,
including: (1) assuring that machines or equipment components are operationally intact; (2)
notifying affected employees that lockout or tagout devices are removed from each energyisolating device by the employee who applied the device.
Energy-Isolating Devices
The employer's primary tool for providing protection under the standard is the energy-isolating
device, which is the mechanism that prevents the transmission or release of energy and to which all
locks or tags are attached. This device guards against accidental machine or equipment start-up or
the unexpected re-energization of equipment during servicing or maintenance. There are two types
of energy-isolating devices: those capable of being locked and those that are not. The standard
differentiates between the existence of these two conditions and the employer and employee
responsibilities in each case.
When the energy-isolating device cannot be locked out, the employer must use tagout. Of course,
the employer may choose to modify or replace the device to make it capable of being locked. When
using tagout, the employer must comply with all tagout-related provisions of the standard and, in
addition to the normal training required for all employees, must train his or her employees in the
limitations of tags.
Limitations of tags includes, but is not limited to, the following elements
Tags are essentially warning devices affixed to energy-isolating devices and do not provide
the physical restraint of a lock.
When a tag is attached to an isolating means, it is not to be removed except by the person
who applied it, and it is never to be bypassed, ignored, or otherwise defeated.
Tags must be legible and understandable by all employees.
Tags and their means of attachment must be made of materials that will withstand the
environmental conditions encountered in the work-place.
Tags may evoke a false sense of security. They are only one part of an overall energy
control program.
Tags must be securely attached to the energy-isolating devices so that they cannot be
detached accidentally during use.
If the energy-isolating device is lockable, the employer shall use locks unless he or she can prove
that the use of tags would provide protection at least as effective as locks and would assure "full
employee protection."
Full employee protection includes complying with all tagout related provisions plus implementing
additional safety measures that can provide the level of safety equivalent to that obtained by using
lockout. This might include removing and isolating a circuit element, blocking a controlling switch,
opening an extra disconnecting device, or removing a valve handle to reduce the potential for any
inadvertent energization.
Although OSHA acknowledges the existence of energy-isolating devices that cannot be locked out,
the standard clearly states that whenever major replacement, repair, renovation or modification of
machines or equipment is performed and whenever new machines or equipment are installed, the
employer must ensure that the energy-isolating devices for such machines or equipment are
lockable. Such modifications and/or new purchases are most effectively and efficiently made as
part of the normal equipment replacement cycle. All newly purchased equipment must be lockable.
Requirements for Lockout and Tagout Devices
When attached to an energy-isolating device, both lockout and tagout devices are tools that the
employer can use in accordance with the requirements of the standard to help protect employees
from hazardous energy. The lockout device provides protection by holding the energy-isolating
device in the safe position, thus preventing the machine or equipment from becoming energized.
The tagout device does so by identifying the energy-isolating device as a source of potential
danger; it indicates that the energy-isolating device and the equipment being controlled may not be
operated until the tagout device is removed. Whichever devices are used, they must be singularly
identified and must be the only devices used for controlling hazardous energy,.
Requirements for Lockout and Tagout Devices
Durable. Lockout and tagout devices must withstand the environment to which they are
exposed for the maximum duration of the expected exposure. Tagout devices must be
constructed and printed so that they do not deteriorate or become illegible, especially when
used in corrosive (acid and alkali chemicals) or wet environments.
Standardized. Both lockout and tagout devices must be standardize according to either
color, shape, or size. Tagout devices must also have a standardized print and format.
Substantial. Lockout and tagout devices must be substantial enough to minimize early or
accidental removal. Locks must be substantial to prevent removal except by excessive
force of special tools such as bolt cutters or other metal cutting tools. Tag means of
attachment must be non-reusable, attachable by hand, self-locking and non-releasable, with
a minimum unlocking strength of no less than 50 pounds.
The device for attaching the tag also must have the general design and basic characteristics
equivalent to a one-piece nylon cable tie that will withstand all environments and
Identifiable. Locks and tags must clearly identify the employee who applies them. Tags
must also warn against hazardous conditions if the machine or equipment is energized and
must include a legend such as the following: DO NOT START, DO NOT OPEN, DO NOT
Employee Training
The employer must provide effective initial training and retraining as necessary and must certify
that such training has been given to all employees covered by the standard. The certification must
contain each employee's name and dates of training.
For the purposes of the standard, there are three types of employees - authorized, affected, and
other. The amount and kind of training that each employee receives is based upon (1) the
relationship of that employee's job to the machine or equipment being locked or tagged out, and (2)
the degree of knowledge relevant to hazardous energy that he or she must possess.
For example, the employer's training program for authorized employees (those who are charged
with the responsibility for implementing the energy control procedures and performing the service
and maintenance) must cover, at minimum, the following areas:
details about the type and magnitude of the hazardous energy sources present in the
workplace, and
the methods and means necessary to isolate and control those energy sources (i.e., the
elements of the energy control procedure(s).)
By contrast, affected employees (usually the machine operators or users) and all other employees
need only be able to (1) recognize when the control procedure is being implemented, and (2)
understand the purpose of the procedure and the importance of not attempting to start up or use the
equipment that has been locked or tagged out.
Because an "affected" employee is not one who is performing the service of maintenance, that
employee's responsibilities under the energy control program are simple: Whenever there is a
lockout or tagout device in place on an energy-isolating device, the affected employee leaves it
alone and does not attempt to operate the equipment.
Every training program must ensure that all employees understand the purpose, function and
restrictions of the energy control program and that authorized employees possess the knowledge
and skills necessary for the safe application, use, and removal of energy controls.
Training programs used for compliance with this standard, which is performance-oriented, should
deal with the equipment, type(s) of energy, and hazard(s) specific to the workplace being covered.
Retraining must be provided, as required, whenever there is a change in job assignments, a change
in machines, equipment or processes that present a new hazard, or a change in energy control
procedures. Additional retraining must be conducted whenever a periodic inspection reveals, or
whenever the employer has reason to believe, that there are deviations from or inadequacies in the
employee's knowledge or use of the energy control procedure.
Periodic Inspections
Periodic inspections must be performed at least annually to assure that the energy control
procedures (locks and tags) continue to be implemented properly and that the employees are
familiar with their responsibilities under those procedures. In addition, the employer must certify
that the periodic inspections have been performed. The certification must identify the machine or
equipment on which the energy control procedure was used, the date of the inspection, the
employees included in the inspection, and the name of the person performing the inspection. For
lockout procedures, the periodic inspection must include a review, between the inspector and each
authorized employee, of that employee's responsibilities under the energy control procedure being
inspected. When a tagout procedure is inspected, a review on the limitation of tags, in addition to
the above requirements, must also be included with each affected and authorized employee.
Application of Controls and Lockout/Tagout Devices
The established procedure of applying energy controls includes the specific elements and actions
that must be implemented in sequence.(3) These are briefly identified as follows:
1. Prepare for shut down.
2. Shut down the machine or equipment.
3. Apply the lockout or tagout device.
4. Render safe all stored or residual energy.
5. Verify the isolation and de-energization of the machine or equipment.
Removal of Locks and Tags
Before lockout or tagout devices are removed and energy is restored to the machine or equipment,
the authorized employee(s) must take the following actions or observe the following procedures:
1. Inspect the work area to ensure that non-essential items have been removed and that
machine or equipment components are intact and capable of operating properly;
2. Check the area around the machine or equipment to ensure that all employees have been safely
positioned or removed;
3. Notify affected employees immediately after removing locks or tags and before starting
equipment or machines; and
4. ONLY those employees who attached locks or tags are authorized to remove them. In the very
few instances when this is not possible, the device may be removed under the direction of the
employer, provided that he or she strictly adheres to the specific procedures outlined in the
Additional Safety Requirements
Special circumstances exist when
1. outside (contractor) personnel are at the worksite,
2. machines need to be tested or repositioned during servicing,
3. servicing or maintenance is performed by a group (rather than one specific person), and
4. shift changes or personnel changes occur.
Testing or Positioning of Machines
OSHA allows the temporary removal of locks or tags and the re-energization of the machine,
ONLY when necessary under special conditions. For example, when power is needed for the
testing or positioning of machines, equipment, or components. The re-energization must be
conducted in accordance with the sequence of steps listed below:
1. Clear the machines or equipment of tools and materials.
2. Remove employees from the machines or equipment area.
3. Remove the lockout or tagout devices as specified in the standard.
4. Energize and proceed with testing or positioning.
5. De-energize all systems, isolate the machine or equipment from the energy source, and
reapply lockout or tagout devices as specified:
• Outside personnel (contractors, etc.) The onsite employer and the outside employer
must inform each other of their respective lockout or tagout procedures. Each employer
must ensure that his or her personnel must understand and comply with all restrictions
and/or prohibitions of the other employer's energy control program.
• Group lockout or tagout. During all group lockout/tagout operations where the release
of hazardous energy is possible, each authorized employee performing service or
maintenance shall be protected by his/her personal lockout or tagout device or
comparable mechanism that affords equivalent protection.
Shift or personnel changes. Specific procedures must ensure the continuity of lockout
or tagout protection during shift or personnel changes.
A respirator is designed as an enclosure that covers the nose and mouth or the entire face or head.
The purpose of a respirator is to prevent the inhalation of harmful airborne substances. The
purpose of this training program is to share with you information about respirators and respiratory
hazards with which you may come in contact. Armed with the proper information, we know you
will make wise choices to protect your health and well-being. We’ll be explaining basic
terminology, sharing with you the different types of respirators and filters, discussing proper fit,
explaining the use and limitations, and explaining maintenance of respirators.
Before you can properly select a respirator, you need to know some basic terminology. We’ll
discuss the hazards later. Right now, concentrate on understanding the basic terms and meaning of
these words and phrases. We’re not giving you exact terminology of these words or phrases, just
some basic information, so you’ll have an understanding of what they mean, in a general sense:
Permissible Exposure Limit (PEL)
PEL’s are exposure limits for each different chemical.
Established by OSHA, PEL’s may be expressed as a time-weighted average (TWA) or as a ceiling
exposure limit.
Threshold Limit Values (TLV) TLV’s are used by industrial hygienists to express the airborne
concentration of a material to which nearly all workers can be exposed day after day, without
adverse effects. Each chemical or airborne concentration has different TLV’s.
Oxygen Deficiency Oxygen Deficiency simply means there isn’t enough oxygen in the air to
support life.
Self Contained Breathing Apparatus (SCBA) These respirators are used in oxygen deficient
atmospheres and where filtering cartridges or face piece respirators would not provide sufficient
protection. Oxygen cylinders provide the air needed for breathing.
Immediately Dangerous to Life and Health (IDLH) All oxygen deficient atmospheres must be
considered IDLH. There are exceptions to this rule, but there are many technicalities that must be
met, so in general, oxygen deficient atmospheres are considered IDLH. If an atmosphere is IDLH,
the employer must provide the following respirators: a full face piece, NIOSH certified SCBA
with a minimum service life of 30 minutes or a full face piece pressure demand airline respirator
with auxiliary self-contained air supply. If a respirator is to be used for escape from an IDLH
atmosphere only, the respirator must be NIOSH certified for escape from the atmosphere in which
it will be used. Generally, these escape respirators are available for 5 or 10 minute uses.
Particulate The word particulate means a particle of solid or liquid matter. Matter is comprised of
three states: solids, liquids, and gases. Solids Particulates are either finely divided dust particles,
such as from grinding operations or as still more finely divided metal fume particles, as generated
when smoldering hot metals vaporize. They combine with oxygen in the air and condense as oxide.
Hazard ratio is the hazard concentration and the exposure limit for the contaminant.
Assigned Protection Factors(APF) This is the minimum anticipated protection provided by a
properly functioning respirator or class of respirators to a given percentage of properly fitted and
trained users. Generally, respirators have APF’s of 10 or greater than 10. An APF of 10 is for half
masks and 50 for full face masks air-purifying respirators
End of Service Life Indicator (ESLI) The ESLI will be provided by the respirator manufacturer,
indicating the life of the respirator. After that ESLI has expired, the respirator can no longer be
used. Where there is no ESLI, your employer must develop change schedules for respirators. This
means that based upon the chemicals or contaminants in the air, a respirator’s filter or cartridge
must be changed every two hours, four hours, or the established schedule developed for that
particular respirator. If the respirator does not have an ESLI or there is no change schedule
established, then a supplied air respirator must be used.
It takes time and effort to fully understand the terminology and meaning of respirator related
equipment, atmosphere concentrations, and all the things you need to protect your health. Hang in
there with us; more information is necessary when you’re selecting respirators.
There are two major classifications of respirators and these are air purifying and atmosphere
supplying respirators.
Air purifying Respirators
Air purifying respirators remove contaminants such as particulate, vapor and gas or a combination
of both, but they do not supply oxygen. An air-purifying respirator cannot be used in an oxygen
deficient or IDLH atmosphere. The respirator should be equipped with a NIOSH certified ESLI or
on a change schedule based on objective data to ensure that the cartridges are changed before the
end of their service life.
Air purifying respirators are grouped into three general types: particulate removing, vapor and gas
removing, and combination. Elements that remove particulates are called filters, while vapor and
gas removing elements are called either chemical cartridges or canisters.
Filters and
canisters/cartridges are the functional portion of air-purifying respirators, and they can generally be
removed and replaced once their effective life has expired. The exception would be disposable
respirators, those, which cannot be cleaned and disinfected or refitted with an unused filter after
each use. Combination elements are those that protect for both particulates and vapors and gases.
Atmosphere-supplying Respirators
This type of respirator provides oxygen to the employee. An atmosphere-supplying respirator
equipped with a NIOSH certified HEPA filter or an air-purifying respirator equipped with NIOSH
certified filter for particulates provide protection against particulates.
There are many types of respiratory hazards that may result from an oxygen deficient atmosphere
or from breathing air contaminated with toxic particles, vapors, gases, fumes or mists. The proper
selection and use of a respirator depends upon an initial determination of the concentration of the
hazard(s) present in the workplace. Keep in mind that NIOSH certifications are minimum
standards. This certification may not protect from exposures in every case, so each organization
must assess the exposure and recommend the proper respirator for that particular hazard or hazards
Powered Filtering Respirators
Powered filtering respirators are simply respirators that have small motors that increase air flow
through the respirator. They may be either air-purifying or atmosphere-supplying respirators.
Certification of respirators are obtained for the complete respirator assembly, not just the filters.
Filters vary according to the atmosphere they are to filter. There are three series of filters: N, R,
and P. To help you remember the difference between the N, R and P filters, think about oil. Oil in
the air makes a big difference in the type of filter you select.
The N designation means the filter is NOT RESISTANT to oil.
The R designation means the filter is RESISTANT to oil, but not oil proof.
The P designation means the filter is oil PROOF.
Respirator filters are tested against the most penetrating size of aerosol, hygiene factors, damaging
air contaminates and breathing resistance. Efficiency ratings are granted depending on the amount
of filter leakage that can be accepted. The higher the efficiency rating, the lower the filter leakage.
Each series will have an efficiency rating.
N95, R95, P95. The 95 number means it is 95 percent efficient.
N99, R99, P99 means filters have a minimum efficiency of 99 percent.
N100, R100, P100 means these filters have a 99.7 percent efficiency rating.
The N Series Filter
The N series filter is limited to use in atmospheres containing non-oil-based particulates. It cannot
be used if oil particles are present, such as those generated when cutting oil covered steel.
Generally, these filters have a time-use restriction of eight hours.
The R and P Series Filters.
Both the R and P series are intended for filtering any non-oil or oil containing particles. If oil
particles, such as lubricants or cutting fluids are present, use an R or P series filter Eight-hour time
usage is also generally eight hours. The P series may be used in either a non-oil or oil-containing
atmosphere and do not have by time restrictions other than those normally associated with
particulate filters. If oil particles are present, and the filter is to be used for more than one work
shift, use only a P series filter. When selecting respirators, look for the NIOSH certification
number 84A. This means it has the new certification. There are no requirements for color coding
on respirators or cartridges, except the P100 filter. The P100 respirators will be color coded
. Respirators are of two general “fit” types. Tight fitting and full face piece. Tight fitting
respirators, such as quarter masks which cover the mouth and nose and where the lower sealing
surface rests between the chin and the mouth. The half mask, which fits over the nose and under
the chin and the full face piece, which covers from the hairline to below the chine. There are also
loose fitting hoods, helmets or full suits that cover the head completely.
Donning a Respirator
Anyone wearing a respirator must be trained and authorized by the company in several different
areas, such as how to put on and take off the respirator. We call that donning and doffing. You are
being asked to select the respirator that provides the most acceptable fit. A mirror must be
provided to assist you in evaluating the fit and positioning of the respirator. Each respirator
represents a different size and shape and if fitted and used properly, will provide adequate
protection. Hold each face piece up to the face and eliminate those that do not give you an
acceptable fit. Put the most comfortable mask on your face and wear it for at least five minutes. If
you’re not experienced wearing a respirator, put it on and take it off several times, to become
familiar with the process. Adjust the straps each time the respirator is donned. While wearing the
respirator, check the comfort of the mask, how it fits your face, nose and proper seal between the
mask and your face and cheeks. Make sure your chin fits the respirator. Check the strap tension;
make sure it’s not too loose or too tight. Some respirators have a tendency to slip, so check the fit
in the mirror and through testing of the fit. Move your mouth as if talking to make sure you don’t
break the seal or fit.
Seal Checks
Before conducting the negative and positive pressure checks, seat the mask on your face and move
your head from side to side, and up and down. Ensure a stable fit. Make sure there is room for eye
protection and good vision. If you wear glasses, the glasses cannot extend through the seal of the
mask. Conduct seal checks. If you have any facial hair or sideburns that would prevent a proper
seal, you cannot wear or select the respirator. While selecting or wearing a respirator and you have
any difficulty in breathing, you must be provided a medical evaluation before being allowed to use
respiratory protection. To conduct a positive pressure seal check, close off the exhalation valve and
exhale gently into the face piece. The face fit is considered satisfactory if a slight positive pressure
can be built up inside the face piece without any evidence of outward leakage of air at the seal.
This method of leak testing requires the wearer to first remove the exhalation valve cover before
closing off the valve, and then carefully replace it after the test.
The negative pressure test is conducted by closing off the inlet opening of the canister or cartridges
by covering with the palm of the hands or by replacing the filter seals. Inhale gently so the face
piece collapses slightly, and hold your breath for 10 seconds. The design of the inlet opening of
some cartridges cannot be effectively covered with the palm of the hand. If this occurs, the test can
be performed by covering the inlet opening of the cartridge with a thin latex or nitrile glove. If the
face piece remains in its slightly collapsed condition and no inward leakage of air is detected, the
tightness of the respirator is considered satisfactory. If the respirator manufacturer recommends a
different seal check, then their recommendations should be followed.
Doffing a Respirator
To remove the respirator, you should loosen the straps and while pulling on the straps. Allow the
mask to gently release from the face seal. Upon removing the mask, it should be cleaned,
disinfected, and stored according to the manufacturer’s recommendations.
REMEMBER that identification of the hazard is the first step in selecting respirators. This means
identifying the respiratory hazards and the level of employee exposure. If you’ve confirmed that
the atmosphere is not IDLH, and it is not oxygen deficient, and the hazard is a particulate, then you
need to select a particulate respirator. You’ll need to know the HAZARD RATIO for the
contaminant. Hazard ratio is the hazard concentration and the exposure limit for the contaminant.
Generally technically qualified individuals who have the proper contaminant testing equipment
determine the hazard ratio. If the hazard ratio is less than 10, you may use a half mask airpurifying respirator with a filter efficiency of 95 percent or higher. If the hazard ratio is less than
20, you may use a full face piece air-purifying respirator with a filter efficiency of 99 percent or
higher. Keep in mind the oil in the air. This makes a difference in the filter classification. If the
hazard ratio is determined to be 100 or greater, then you must use an atmosphere-supplying
respirator. Manufacturers of respirator equipment will generally provide your company with a
particulate and hazard ratio flow chart to help in the selection of the proper respirator.
Routine Use
Respirators for use in non-emergency situations are to be inspected before each use and during
Emergency Use
Respirators designated for use emergency situations should be inspected at least monthly and in
accordance with the manufacturer’s recommendations. Emergency respirators must be examined
to ensure they are working properly before and after each use. A basic examination of the
equipment conducted prior to each use will provide assurance to the wearer that the respirator,
which is about to be used in an emergency, will work properly. This includes that cylinders on the
SCBA are charged the air is available and flowing.
Escape Only Use
Respirators used for escape only, are to be inspected prior to being carried into the workplace.
Mouth bit or other emergency escape respirators are carried into the workplace for use by one
person in an emergency and must be inspected for proper condition prior to being carried into the
workplace. Therefore, escape-only respirators need only be inspected before being carried into the
Inspection procedures must include the respirator is working properly, and all connections are tight
and all the various components of the respirator are functioning properly and in good condition.
When there is an IDLH situation, a standby person must be in communications with people in the
IDLH atmosphere. This standby person must be properly fitted with respiratory equipment and be
adequately prepared to facilitate rescue attempts. Prior to entering an IDLH atmosphere for rescue,
the standby rescue person should notify management to take the responsibility for the rescue and to
make sure the rescue is carried out appropriately. The employer should be advised of the rescue to
ensure the rescue is necessary and that an emergency response team has been advised of the
emergency. No one should enter an IDLH atmosphere that has not been properly trained or is not
wearing appropriate respiratory protection.
Not all workers can wear respirators. Individuals with impaired lung function, due to asthma or
emphysema for example, may be physically unable to wear a respirator. Individuals who cannot
get a good face piece fit, including those individuals whose beards or sideburns interfere with the
face piece seal, will be unable to wear tight fitting respirators. An adequate fit is necessary for a
respirator to be effective.
In addition to these problems, respirators may restrict communications or vision. Fatigue and
reduced work efficiency are also potential problems when wearing respirators. Keep in mind there
are many considerations to be taken into account when selecting respirators. Heavy breathing due
to overexertion on a particular job will increase the air used, so this could reduce the amount of
supplied air available and you would not be able to stay in an atmosphere as long as you would
normally. Some people will have reduced capabilities by simply wearing a respirator. Heat,
humidity, extremely cold weather may affect the type of respirator selected. Proper seals on the
face, fit of the respirator on different sizes of faces….All these things must be taken into
A worker who must speak loudly to communicate may experience a seal leak. It’s important for all
respirator users to understand the signs and symptoms of improper seals or wearing of respirators.
Quite often, the user, for a variety of reasons does not detect seal leaks. It could be that the user
has been desensitized to the odor or quite possibly there is no odor, yet the user is exposed to these
If during the time you are using a respirator you begin to feel faint, dizzy, have headaches, become
nauseous, or have any abnormal health effects, get out of the atmosphere immediately. Have your
respirator tested for proper seal, fit and to make sure the filtering cartridge or filter is working
properly. No need to take chances.
To fully understand the health effects and symptoms of each chemical used, you should review and
understand the Material Safety Data Sheet or MSDS that is maintained in your workplace. Each
chemical is different, with different exposure reactions. Respirators are used to protect you from
health hazards, but you should be aware of the symptoms for any unplanned exposures. All the
potential hazards in the workplace and potential problems associated with respirator use must be
taken into consideration when selecting respiratory protective equipment.
When using atmosphere-supplying respirators, the suppliers of breathing air must now provide a
certificate of analysis to verify that the breathing air meets the requirements of type 1, grade D.
This certifies that the air supplied meets breathing air quality standards. It is advisable that this
certification verification be documented in your company’s files and if the vendor is changed, to
obtain certification from the new vendor.
Filtering face piece is new terminology for dust masks. A number of instances may arise where
there are no contaminants or threats to a person’s health; however, some people may feel more
comfortable wearing a filtering face piece. If respirator use is strictly voluntary, you must develop
certain parts of the respirator program to ensure the face pieces that are worn are kept clean and in a
sanitary condition. Furthermore, the user must be medically capable to wear the respirator and
trained in its limitations. This requires standard operating procedures, medical evaluations, training
and maintenance. Filtering face pieces are to be single use, which means only one person may
wear the filtering face piece. The voluntary use of filtering face pieces is strictly for comfort and
not protection. In some cases, the wearing of a filtering face piece in itself can be hazardous. Be
sure each person who voluntarily wears a face piece has been evaluated as being medically
qualified to wear it. If filtering face pieces are mandatory, then a comprehensive written program
and training are required, just as is the case with other types of respirators.
Self contained breathing apparatus, SCBA, and air supplied respirators are a bit more complicated
and require additional training. This information is contained in another training program.
Respirators must be maintained in a clean, sanitary condition. After each use, respirators must be
cleaned, disinfected and properly stored. The information on how to clean and maintain respirators
will be covered in other training programs.
Selection of respirators requires knowledge, thought, planning and understanding the hazards in the
workplace. Just because a respirator is new and looks great… that doesn’t mean it works for your
particular hazards. It requires special effort and training to make sure you use the proper respirator
for the potential exposure. If you follow the rules, company policies and procedures, you will be
much more capable of protecting your health. Respirator selection is an important part of your job
responsibilities, so don’t take the job lightly. Be informed and put your knowledge and good
judgment to work for you.
This short program explains the rules and procedures for proper fit testing of respiratory equipment
as defined by the National Institute of Occupational Safety and Health (NIOSH). These standards
have established filtering efficiency and performance criteria for all non-powered, air-purifying,
particulate-filter respirators. The purpose of fit testing is to make sure the respirator you use will
not leak, under normal use and working conditions. Almost any respirator you use will appear to
fit, but individuals wearing a respirator may not always be able to detect a leak; therefore, a
comprehensive fit testing program is necessary.
The standard allows respirator users to continue using and purchasing AIR-PURIFYING and
PARTICULATE-FILTER respirators certified under previous standards. Before an employee may
be required to use any respirator with a negative or positive pressure tight-fitting face piece, the
employee must be fit tested with the same make, model, style and size of respirator that will be
used. The employer shall ensure employees using a tight-fitting face piece respirator pass an
appropriate qualitative fit test or quantitative fit test.
Fit testing a respirator determines the quality of the respirator-to-face seal and is the only way to
screen out poorly fitting face pieces. A fit test should not be confused with a “fit check or user seal
check”. The fit check or user seal checks are used only to verify that a respirator is seated properly
before a fit test or before entering a work area with a previously fitted respirator. The two basic
types of fit tests are quantitative and qualitative.
Quantitative fit testing provides a numerical or scientific measurement of the respirator fit. It is the
most accurate type of fit testing. Quantitative fit testing is performed by challenging the seal of a
probed respirator, equipped with P100 HEPA filters, to a challenge aerosol that is easily detected
by the fit test instrument or by measuring the pressure inside the face pieces during a controlled
Negative Pressure fit test. The words “challenge aerosol” refers to approved materials, such as
smoke or other aerosols that can be detected by a human being.
A probed respirator is one that has a probe inside the respirator, for measuring pressure. The
“challenge aerosol” material is something that is not harmful, but it can be easily detected with
sensitive instruments. A fit testing instrument will monitor the aerosol concentration both inside
and outside the face piece during this test or the instrument will calculate the pressure differences
between the inside and outside, to determine if there is any leakage. Next, the instrument will either
report these concentrations or calculate the wearer’s fit factor. A “fit factor” is the ratio of the
concentration outside the face piece divided by the concentration inside the face piece or a measure
of the leakage rate.
While this “fit factor” represents the actual fit of the respirator in a TEST ENVIRONMENT, an
assigned protection factor or APF is a limit set by an applicable regulatory agency. When the
assigned protection factor and the fit factor are compared, the fit factor must exceed the APF by at
least ten times in order for the fit to be adequate. Let’s say that again. When the assigned
protection factor and the fit factor are compared, the fit factor must exceed the APF by at least ten
times in order for the fit to be adequate. This means you need to know and understand Assigned
Protection Factors or APF’s to make sure you have a proper for the potential hazard.
For example, a half mask respirator has an assigned protection factor of ten. Therefore, the wearer
must achieve a fit factor ten times greater than the APF or 100. This safety factor may be set
higher at the discretion of the respiratory program administrator.
A probed respirator is a respirator that has been modified by the manufacturer to provide a
sampling port through which internal air can be monitored. This “probed” respirator can only
Another practical alternative is a fit test adapter. This adapter allows the conversion of a working
respirator to be fitted with a probe. An advantage to this procedure is the wearer can be fit tested in
his or her own respirator.
Qualitative fit testing is not accurate and merely provides a pass/fail result without obtaining a
numerical or scientific measurement. In this type of test, the respirator’s face-to-face seal is
challenged with a substance detectable by the human senses, such as smell or taste. The test
subject is relied upon to provide an unbiased and honest response. Since the test subject is the
person who will be detecting the smell or taste of the testing material, pre-screening is necessary to
demonstrate an ability of the person being tested to detect the test agent. A qualitative fit test
would be extremely unsatisfactory if the person being tested could not detect or smell the testing
Every human being is different. Some people have very sensitive senses, such as some people can
detect a very minor odor, while another person would have to be saturated with an odor before they
could smell it. That’s why qualitative fit testing is not scientifically accurate, but it does have value
in helping respirator wearers evaluate the respirator they will be wearing will protect their health
from potential hazards. The qualitative test only verifies a protection factor of ten. If more
protection is required, then a quantitative fit test must be performed. During the qualitative fit test,
if the person’s senses detect the substance inside the face piece, the respirator being tested fails.
Commonly used aerosols and testing substances include irritant smoke and bitrex. These materials
are designed for the safety of the person being tested and for the strength of the test material for
proper detection. Although passing a qualitative fit test only verifies a protection factor of ten, this
type of fit test can be used to comply with the new fit testing requirements for all tight fitting face
piece respirators, up to a protection factor of ten.
Some disadvantages of qualitative fit test protocols is the subjectivity of the test as well as lack of
information on the magnitude of the respirator leakage. Other limitations are the ability of the
subject to detect the test agent and the type of response it elicits. The only recourse in overcoming
these limitations is to perform a quantitative fit test, with scientific or numerical measurements.
Fit testing of tight-fitting atmosphere-supplying respirators and tight-fitting powered air-purifying
respirators must be accomplished by fit testing in the Negative Pressure Mode regardless of your
choice of qualitative or quantitative testing.
The first requirement in fit testing is to allow the wearer to pick the most acceptable respirator from
a sufficient number of respirator models and sizes so the respirator is acceptable to and correctly
fits the user. These sufficient numbers of models do not have to be from different manufacturers.
Proper training must be provided relating to donning, doffing and adjustment of tension straps on
the respirator. If a person is not familiar with these procedures, additional training in donning and
doffing must be provided. The person should make sure the respirator fits comfortably, including
the position of the mask on the nose, room for eye protection, room for talking, position of the
mask on the face and cheeks, chin placement, adequate strap tension, proper fit across the nose
bridge, proper size to span the distance from the nose to the chin and tendency of the respirator to
slip. A mirror must be provided to evaluate fit and respirator position.
During the fit test, the test subject will perform various exercises to determine the effectiveness of
the fit and seal of the respirator. The tested person should perform as many different exercises that
would closely relate to respirator use in a normal working environment. Depending on the type of
test, these may or may not include:
Normal breathing………….. deep breathing……….turning the head side to side…… moving the
head up and down……talking….grimacing ….. bending over or jogging in place….. and normal
breathing again. These exercises are performed in the above order for one minute, except for the
grimace exercise, which is performed for only 15 seconds.
The objective to perform enough exercises to demonstrate that the seal of the respirator is
satisfactory for normal, routine respirator use. Proper fit testing is an important element of any
respirator program. No matter what else you do, if a respirator doesn’t fit properly, it’s useless.
The standards require fit testing on all tight-fitting face pieces, including air-supplying and
powered air-purifying respirators. Fits tests are required annually, and after a significant change in
the type or model of respirators. Also, fit testing is required if there is a physical change in a
person, such as weight gain or loss, …..facial scarring.... …cosmetic surgery …… substantial
dental work or other factors that could affect the wearing of the respirator.
There are other conditions of respirator use that can affect the fit. Nothing must interfere with the
seal of a tight-fitting respirator, including facial hair and glasses. If beards are trimmed so they do
not break the respirator, this is acceptable. HOWEVER, the fit test shall not be conducted if there
is any hair growth, beard, mustache or sideburns, which cross the respirator sealing surface. In the
example shown here, would this person be allowed to fit test or wear a respirator under this
condition? The answer is no. There is facial hair stubble that may interfere with an appropriate
seal between the face and respirator. There must be a proper seal before anyone may be fit tested
or wear a respirator.
Each time a worker puts on a respirator, a user seal check is required. These seal checks are not
substitutes for fit testing. Exactly how do you perform these seal checks?
is performed by closing off the exhalation valve and exhales gently
into the face piece. The face fit is considered satisfactory if a slight positive pressure can be built
up inside the face piece without any evidence of outward leakage of air at the seal.
is performed by covering the inlet opening of the canister or
cartridges and inhale gently so the face piece collapses slightly… and you hold your breath for 10
seconds. If the face piece remains in the slightly collapsed condition…. and no inward leakage of
air is detected; the tightness of the respirator’s seal to the face is considered satisfactory. The
purpose of fit testing and seal checks is to make sure there is a proper fit and seal, without any
leakage inside the respirator. Fit testing and seal checks are mandatory.
The respirator plan requires extensive employee training in all aspects of respirator use, selection,
fit testing, maintenance, and of course, the respirator program must be written. Documentation of
all training, testing, repairing and maintenance is required. One of the more important parts of the
respirator program will be if employees can answer some of the following questions:
1. Has your respirator been properly fit tested?
2. Do you know the proper procedures for selecting respirators?
3. Have you completed a medical questionnaire and has a health professional evaluated your
health to ensure you are able to wear a respirator?
4. Do you know how to properly conduct a seal check?
5. Have you been trained in the various aspects of respiratory protection?
6. Do you know the capabilities and limitations of respirators?
7. Do you know how to properly care for and maintain respiratory equipment?
8. Can you recognize the signs and symptoms that may limit or the effective use of respirators?
These questions will help evaluate the effectiveness of your company’s respiratory protection
program. Of course, appropriate surveillance shall be maintained of work area conditions and
degree of exposure or stress. When there is a change in work area conditions or exposure, the
employer shall reevaluate the continued effectiveness of the respirator.
After employees leave a respirator use area, they should wash their hands and faces and respirator
face pieces as necessary to prevent eye or skin irritation associated with respirator use. Naturally,
if the wearer experiences any difficulty, leakage, changes in breathing resistance, the respirator
must be cleaned and tested. If the respirator is defective it must be repaired or replaced. Proper
maintenance, cleaning, storing and inspecting respirators is an important part of the respiratory
protection program.
The use of respirators is simply one method of helping protect the health of people working in
environments where their health could be affected, if this protection were not used. If respiratory
protection is not used, or used improperly, in these environments and conditions, then the worker’s
health could be impaired. It’s up to the company to provide the training, equipment, and
supervision. The most important element of the program is the wearer’s responsibility in following
the rules and regulations established by the company. The respirator wearer’s attitude towards
safety and complying with the standards will make the difference between an effective program
and a less than effective program. Protection of your health is the goal of the respirator program.
Note: This may not be applicable to this industry, unless you have First Aid/CPR trained employees; however, it is
useful information for all employee training programs.
This is NOT a written Bloodborne Pathogens plan. It’s information to inform all employees about
the potential of developing a serious illness, if they come in contact with blood or body fluids of a
person who is ill with various diseases/viruses.
It is most applicable to anyone who is trained as a First Aid or CPR provider. If you have
employees that are exposed to blood or body fluids, you must have a written Bloodborne Pathogens
Throughout the industrialized world, great strides have been made in promoting knowledge about
Bloodborne Pathogens. Training programs, such as this one have been designed to educate people
about the hazard and the protective measures that should be used to avoid exposure to Bloodborne
Pathogens. This updated program will discuss and demonstrate proper methods of infection
control and exposure control that will help you to avoid the risk of contamination with potentially
infectious materials.
There are governmental regulations and standards relating to bloodborne pathogens. The purpose
of these standards is to eliminate or to minimize an employee’s risk of an occupational exposure to
Hepatitis B virus, HBV, to the Human Immunodeficiency Virus, also referred to as HIV, and to
other potentially infectious bloodborne pathogens. These standards do not automatically apply to
employees if they are trained in first aid; however, they do apply to employees who are required
by their employer to administer first aid. People who perform unanticipated Good Samaritan Acts
are not held to these same standards, but certainly it is an advantage to be aware of the
precautionary measures that should be taken to avoid an exposure.
Before we go further let’s define a few key words.
Occupational Exposure A reasonably anticipated skin, eye, mucous membrane, or skin puncture,
contact with blood or other potentially infections materials that may result from the performance.
of an employee’s duties.
Bloodborne A microscopic organism or substance carried by the blood or fluid systems of the
body is said to be bloodborne.
Pathogens A virus or bacteria causing damage, stress, or disease to the human body.
Although the information is directed at occupational hazards in the workplace, the information in
this program can be used by anyone, regardless of their job. Let’s now examine bloodborne
diseases and what are bloodborne pathogens. Actually, they are bacteria, viruses, and other
microorganisms carried in the blood stream. These microorganisms may cause disease and some
pathogens can be deadly. Some of these pathogens that are of greatest risk include Hepatitis B
virus (HBV), Hepatitis C virus (HCV), and human immunodeficiency Virus (HIV).
Hepatitis B or HBV attacks the liver and is the major infectious bloodborne occupational hazard to
health care workers. HBV is considered to be extremely infectious. The exposure to extremely
small amounts of HBV positive blood may transmit infection. Fortunately, there are vaccines
available to prevent the development of HBV infection.
Hepatitis C infects up to 150,000 people each year in the United States alone. Hepatitis C attacks
and inflames the liver.
Between 8,000 to 10,000 die each year from HCV related chronic liver
disease. People most at risk for HCV include people who have received blood transfusions before
1990, intravenous drug users who share needles, household members and sexual partners of
infected persons, and of course, persons in the medical field who are exposed to infected blood.
Many people who are infected may not experience any signs or symptoms at all. There are tests
now available to assist in making the diagnosis of HCV. Although no preventative medication or
treatment has been conclusive, an antiviral medication is now available that has been shown to be
helpful for some people with HCV.
The Human Immunodeficiency Virus or HIV attacks the body’s immune system, weakening it so
that it cannot fight and destroy other deadly diseases. HIV causes Acquired Immune Disorder
Syndrome or AIDS. AIDS is a fatal disease, and while treatment for it is improving, there is no
known cure.
Some of the other less common bloodborne diseases include Hepatitis D, Malaria, Syphilis, Viral
Hemorrhagic Fever, and Ebola. While we will not be discussing this diseases specifically, all of
the protective techniques that stop or eliminate the spread of disease by bloodborne pathogens will
also be effective against these diseases.
Let’s now take a quick look at how these potentially deadly viruses can pass from one person to
another. The HIV and HBV bloodborne pathogens may be transmitted from the infected individual
to other individuals by blood or Other Potentially Infections Materials (OPIM) such as: semen,
vaginal secretions, fluids around the brain and spinal cord, around the joints, abdomen, uterus,
heart, saliva from dental procedures, or saliva containing blood, breast milk, and any body fluid
visibly contaminated with blood. In situations where it is difficult or impossible to differentiate
between body fluids, it must be assumed to be infectious. Bloodborne pathogens can be
transmitted by any detached body tissue or organ from a human, living or dead. It’s extremely
important for you to understand how exposure and transmission can most likely occur in your
particular work or life setting.
HBV and HIV are most commonly transmitted through sexual contact, sharing of hypodermic
needles, from mothers to their children at or before birth, accidental puncture wounds, contact
between broken or damaged skin and infected body fluids, and contact between mucous
membranes and infected body fluids. You may be at risk if you have had more than one sexual
partner, you have had unprotected sex, you or your partner have ever been diagnosed with another
sexually transmitted disease such as herpes, gonorrhea, syphilis, chlamydia, or genital warts, or if
you or your partner have had unprotected sexual contact with an infected person.
Certainly, your employer must determine which jobs are at risk. The employer must advise those
employees to the exposure risks and the measures to take to reduce such exposure. Occupational
risks include professionals in the health care industry, first responders, such as fire, police,
Emergency Medical Technicians who give first aid and medical attention, or through other
exposures. An occupational risk includes coming into contact with blood or body fluids at work.
A common barrier to action in an emergency is fear of disease transmission between an ill or
injured person and a first aid provider. As an example, the perceived risk of disease transmission
during CPR has reduced the willingness of some laypersons to initiate mouth-to-mouth ventilation
to unknown victims of cardiac arrest. Because of disease transmission concerns, first aid providers
must learn the importance of Standard precautions or body substance isolation. They must know
what steps to take for personal protection from bloodborne pathogens. These steps include how to
use, remove, and discard such equipment. First aid providers are obviously at an increased
exposure risk, and they should have the responsibility of meeting more comprehensive standards.
There are no vaccines or cures for HCV or HIV. However, there is a vaccine for HBV.
Vaccination is your best protection against HBV. The vaccine is given in a series of three doses.
Most often these three doses are taken over a six-month time period. The vaccine works most
effectively when all three doses are taken. If you decide to get the HBV vaccination, you should
check with your doctor and or your employer. The vaccine is safe and effective and is currently
recommended for children as well as adults.
Standard Precautions is a method of infection control. in which all human blood and certain human
body fluids are treated as if they are known to be infectious for any bloodborne pathogen. Standard
Precautions are to be observed in all situations where there is a potential for contact with blood or
other potentially infectious material. Some body fluids may be difficult to differentiate between
other types of body fluid. In this case, all body fluids are to be considered potentially infectious.
A good rule of thumb to follow is: always place a barrier between you and any moist or wet
substance originating from another person. Utilizing Standard Precautions can help protect you,
not only from HBV, HCV, and HIV, but also from all other bloodborne pathogens.
In the workplace, it’s important to be familiar with personal protection Personal protective
equipment (PPE). PPE is considered appropriate if it does not permit blood or other potentially
infectious substances and contaminated materials to pass through or reach your work clothing,
street clothing, undergarments, skin, eyes, mouth, nor other mucous membranes under normal
conditions of use and for the duration of time the protective equipment is in use. To protect
Wash your hands immediately after removal of gloves or other personal protective
Always wear personal protective equipment in exposure situations.
Remove PPE before leaving the work area.
Keep your work area clean and sanitized. Decontaminate area routinely.
Handle and dispose of any sharp items that may be contaminated with extreme caution
by using
mechanical means such as tongs, brush and dustpan or forceps. Never use
bare or gloved hands.
GLOVES should be disposable, single use gloves made of latex or other fluid impervious
materials. Cuts or sores on your hands should be covered with a bandage as additional protection
before applying your gloves. GOGGLES or PROTECTIVE EYEWEAR must be worn whenever there is a
risk of splashing or vaporizing of contaminated fluids. Bloodborne pathogens can be transmitted
through the thin membranes of the eyes, so it is extremely important to protect them.
FACE SHIELDS can be worn in addition to goggles to protect the nose and mouth.
APRONS OR JUMPSUITS prevent contaminated infectious material from reaching clothing,
under garments, and skin surfaces. The material should be appropriate for the level of exposure.
CPR MASK or other mouth to barrier device is strongly recommended.
CAPS and BOOTIES cover the head and shoes completely. Be sure the booties are tied securely.
Any PPE or normal clothing items that become soiled with infectious material must be removed as
soon as possible. Contaminated materials must be handled with caution and placed in an
appropriately labeled bag or container until it is decontaminated or properly disposed.
Along with PPE is the advice that you should never drink, smoke, handle contact lenses, or apply
cosmetics or lip balm until you have left the area containing potentially infectious materials. Do
not leave the area until you have thoroughly washed your hands.
For decontamination and disposal methods, your employer will provide specifically labeled and
color coded containers, such as: Biohazard Bags, sharps items containers, and biohazard laundry
bags. Regulated waste containers are required to be color coded or labeled with the biohazard sign.
These color codes and labels are intended to warn the person who handles the container. Biohazard
symbols and labels must be fluorescent orange, or orange-red with letters or symbols in a
contrasting color. These symbols must be affixed to containers used to store or transport
potentially infectious materials.
One of the most common definitions of an occupational exposure is a specific contact with eye,
mouth, other mucous membrane, non-intact skin, or piercing mucous membranes, or the skin
barrier through such events as needle stick, human bites, cuts and abrasions, contact with blood or
other potentially infectious materials that results from the performance of an employee’s duties. IN
CASE OF AN EXPOSURE, remember these key words: STOP, WASH, and REPORT.
STOP whatever you are doing as soon as possible. WASH the exposed area immediately with
soap and running water. Cleanse thoroughly by scrubbing vigorously and creating a good lather.
Rinse mucous membranes, which is considered the eyes and mouth, with plenty of water. Try to
save any contaminated object for testing purposes. REPORT the incident to your employer as
promptly as possible. Seek medical help, treatment and counseling. If you have not already been
vaccinated against HBV, get vaccinated even after you have been exposed.
Each organization must have an exposure control plan. All new employees must be informed and
trained in these policies and procedures. Workplace exposure control plans are implemented to
eliminate or minimize the employee's exposure to bloodborne pathogens.
When cleaning a spill, you must remember to use Standard Precautions. Protect yourself and
others from exposures. When cleaning, wear appropriate protective gloves and use an appropriate
and approved solution. An inexpensive, approved solution is 10 percent bleach and water or 1/2
cup of bleach to one gallon of water, which is freshly made. You should use disposable towels,
and if necessary, a disposable brush and tray to clean the spill. Everything must be placed in a
biohazard bag and disposed of, according to the workplace exposure control plan. If during work,
you come into contact with IV needles, hypodermic needles, razors, scalpels, scissors, broken
glass, and/or other sharp objects, use extreme caution. Needles should be disposed of by carefully
placing them into an appropriate, labeled, puncture-proof containers designed for sharps. Never
clean up broken sharp materials with your hands. Use a dustpan and brush or tongs. These
materials must to go into sharps containers and not placed in biohazard bags. Contaminated
laundry must be placed into leak resistant labeled containers. If plastic biohazard bags are being
used, they should be doubled as an extra precaution. Remember to wear the proper personal
protection whenever handling soiled/contaminated laundry.
We certainly haven't covered all aspects of bloodborne pathogens, but speak with your employer
and contact your local public health unit for more information on bloodborne pathogens. You can
protect yourself and reduce your risk of exposure to a bloodborne pathogen by the use of personal
protective equipment and practicing Standard Precautions, both at home and at work.
This discussion details the basic steps to handle emergencies in the workplace. These emergencies
include accidental releases of toxic gases, chemical spills, fires, explosions, and bodily harm and
trauma caused by workplace violence. This discussion is intended to assist small businesses that do
not have safety and health professionals. It is not intended as an all inclusive safety program but
rather to provide guidelines for planning for emergencies.
The effectiveness of response during emergencies depends on the amount of planning and training
performed. Management must show its support for plant safety programs and the importance of
emergency planning. If management is not interested in employee protection and in minimizing
property loss, little can be done to promote a safe workplace. It is therefore management's
responsibility to see that a program is instituted and that it is frequently reviewed and updated. The
input and support of all employees must be obtained to ensure an effective program. The
emergency response plan should be developed locally and should be comprehensive enough to deal
with all types of emergencies specific to that site. When emergency action plans are required by a
particular OSHA standard, the plan must be in writing; except for firms with 10 or fewer
employees, the plan may be communicated orally to employees. The plan must include, as a
minimum, the following elements:
1. Emergency escape procedures and emergency escape route assignments,
2. Procedures to be followed by employees who remain to perform, or shutdown, critical plant
operations before the plant is evacuated,
3. Procedures to account for all employees after emergency evacuation has been completed,
4. Rescue and medical duties for those employees who are to perform them,
5. The preferred means for reporting fires and other emergencies, and names or regular job titles
of persons or departments to be contacted for further information or explanation of duties under
the plan.
The emergency action plan should address all potential emergencies that can be expected in the
workplace. Therefore, it will be necessary to perform a hazard audit to determine toxic materials in
the workplace, hazards, and potentially dangerous conditions. For information on chemicals, the
manufacturer or supplier can be contacted to obtain Material Safety Data Sheets. These forms
describe the hazards that a chemical may present, list precautions to take when handling, storing, or
using the substance, and outline emergency and first-aid procedures.
The employer must list in detail the procedures to be taken by those employees who must remain
behind to care for essential plant operations until their evacuation becomes absolutely necessary.
This may include monitoring plant power supplies, water supplies, and other essential services that
cannot be shut down for every emergency alarm, and use of fire extinguishers.
For emergency evacuation, the use of floor plans or workplace maps that clearly show the
emergency escape routes and safe or refuge areas should be included in the plan. All employees
must be told what actions they are to take in emergency situations that may occur in the workplace,
such as a designated meeting location after evacuation.
This plan must be reviewed with employees initially when the plan is developed, whenever the
employees' responsibilities under the plan change, and whenever the plan is changed. A copy
should be kept where employees can refer to it at convenient times. In fact, to go a step further, the
employer could provide the employees with a copy of the plan, particularly all new employees.
A chain of command should be established to minimize confusion so that employees will have no
doubt about who has authority for making decisions. Responsible individuals should be selected
to coordinate the work of the emergency response team. In larger organizations, there may be a
coordinator in charge of plant-wide operations, public relations, and ensuring that outside aid is
called in. Because of the importance of these functions, adequate backup must be arranged so that
trained personnel are always available. The duties of the Emergency Response Team Coordinator
should include the following:
1. Assessing the situation and determining whether an emergency exists that requires activating
the emergency procedures,
2. Directing all efforts in the area including evacuating personnel,
3. Ensuring that outside emergency services such as medical aid and local fire departments are
called in when necessary, and
4. Directing the shutdown of plant operations when necessary.
During a major emergency involving a fire or explosion it may be necessary to evacuate offices in
addition to manufacturing areas. Also, normal services, such as electricity, water, and telephones,
may be nonexistent. Under these conditions, it may be necessary to have an alternate area to
which employees can report or that can act as a focal point for incoming and outgoing calls. Since
time is an essential element for adequate response, the person designated as being in charge should
make this the alternate headquarters so that he/she can be easily reached.
Emergency communications equipment such as amateur radio systems, public address systems, or
portable radio units should be present for notifying employees of the emergency and for contacting
local authorities, such as law enforcement officials, private sector charitable groups, and the fire
A method of communication also is needed to alert employees to the evacuation or to take other
action as required in the plan. Alarms must be audible or seen by all people in the plant and have an
auxiliary power supply in the event electricity is affected. The alarm must be distinctive and
recognizable as a signal to evacuate the work area or perform actions designated under the
emergency action plan. The employer must explain to each employee the means for reporting
emergencies, such as manual pull box alarms, public address systems, or telephones. Emergency
phone numbers should be posted on or near telephones, on employees' notice boards, or in other
conspicuous locations. The warning plan should be in writing and management must be sure each
employee knows what it means and what action is to be taken.
It may be necessary to notify other key personnel such as the plant manager or physician during
off-duty hours. An updated written list of key personnel should be kept listed in order of priority.
Management will need to know when all personnel have been accounted for. This can be difficult
during shift changes or if contractors are on site. A responsible person in the control center must be
appointed to account for personnel and to inform police or Emergency Response Team members of
those persons believed missing.
Emergency Response Teams are the first line of defense in emergencies. Before assigning
personnel to these teams, the employer must assure that employees are physically capable of
performing the duties that may be assigned to them. Depending on the size of the plant there may
be one or several teams trained in the following areas:
1. Use of various types of fire extinguishers,
2. First aid, including cardiopulmonary resuscitation (CPR),
3. Shutdown procedures,
4. Evacuation procedures,
5. Chemical spill control procedures,
6. Use of self-contained breathing apparatus (SCBA),
7. Search and emergency rescue procedures,
8. Incipient and advanced stage firefighting, and
9. Trauma counseling.
The type and extent of the emergency will depend on the plant operations and the response will
vary according to the type of process, the material handled, the number of employees, and the
availability of outside resources. OSHA's Hazard Communication Standard (29 CFR part
1910.1200) is designed to ensure that the hazards of all chemicals produced or imported are
evaluated and that information concerning their hazards is transmitted to employers and employees.
This is done by means of comprehensive hazard communication programs including container
labeling and other forms of warnings, material safety data sheets, and employee training.
Emergency Response Teams should be trained in the types of possible emergencies and the
emergency actions to be performed. They are to be informed about special hazards - such as storage
and use of flammable materials, toxic chemicals, radioactive sources, and water-reactive
substances-to, which they may be exposed during fire and other emergencies. It is important to
determine when not to intervene. For example, team members must be able to determine if the fire
is too large for them to handle or whether search and emergency rescue procedures should be
performed. If there is the possibility of members of the Emergency Response Team receiving fatal
or incapacitating injuries, they should wait for professional firefighters or emergency response
Training is important to the effectiveness of an emergency plan. Before implementing an
emergency action plan, a sufficient number of persons must be trained to assist in the safe and
orderly evacuation of employees. Training for each type of disaster response is necessary so that
employees know what actions are required.
In addition to the specialized training for Emergency Response Team members, all employees
should be trained in the following:
Evacuation plans,
Alarm systems,
Reporting procedures for personnel,
Shutdown procedures, and
Types of potential emergencies.
These training programs must be provided as follows:
Initially when the plan is developed,
For all new employees,
When new equipment, materials, or processes are introduced,
When procedures have been updated or revised,
When exercises show that employee performance must be improved, and
At least annually.
The emergency control procedures should be written in concise terms and be made available to all
personnel. A drill should be held for all personnel, at random intervals at least annually, and an
evaluation of performance made immediately by management and employees. When possible,
drills should include groups supplying outside services such as fire and police departments. In
buildings with several places of employment, the emergency plans should be coordinated with
other companies and employees in the building. Finally, the emergency plan should be reviewed
periodically and updated to maintain adequate response personnel and program efficiency.
Effective personal protection is essential for any person who may be exposed to potentially
hazardous substances. In emergency situations employees may be exposed to a wide variety of
hazardous circumstances, including:
1. Chemical splashes or contact with toxic materials,
2. Falling objects and flying particles,
3. Unknown atmospheres that may contain toxic gases, vapors or mists, or inadequate oxygen to
sustain life,
4. Fires and electrical hazards, and
5. Violence in the workplace.
It is extremely important that employees be adequately protected in these situations. Some of the
safety equipment that may be used includes:
1. Safety glasses, goggles, or face shields for eye protection,
2. Hard hats and safety shoes for head and foot protection,
3. Proper respirators for breathing protection,
4. Whole body coverings chemical suits, gloves, hoods, and boots for body protection from
chemicals, and
5. Body protection for abnormal environmental conditions such as extreme temperatures.
The equipment selected must meet the criteria contained in the OSHA standards or described by a
nationally recognized standards producing organization. The choice of proper equipment is not a
simple matter and consultation should be made with health and safety professionals before making
any purchases. Manufacturers and distributors of health and safety products may be able to answer
questions if they have enough information about the potential hazards involved.
Professional consultation will most likely be needed in providing adequate respiratory protection.
Respiratory protection is necessary for toxic atmospheres of dust, mists, gases, or vapors and for
oxygen-deficient atmospheres. There are four basic categories of respirators:
1. Air-purifying devices (filters, gas masks, and chemical cartridges), which remove contaminants
from the air but cannot be used in oxygen-deficient atmospheres.
2. Air-supplied respirators (hose masks, air line respirators), which should not be used in
atmospheres that are immediately dangerous to life or health.
3. Positive-pressure self-contained breathing apparatus (SCBA), which are required for unknown
atmospheres, oxygen-deficient atmospheres, or atmospheres immediately dangerous to life or
4. Escape masks.
Before assigning or using respiratory equipment the following conditions must be met:
1. A medical evaluation should be made to determine if the employees are physically able to use
the respirator.
2. Written procedures must be prepared covering safe use and proper care of the equipment, and
employees must be trained in these procedures and in the use and maintenance of respirators.
3. A fit test must be made to determine a proper match between the face piece of the respirator
and the face of the wearer. This testing must be repeated periodically. Training must provide
the employee an opportunity to handle the respirator, have it fitted properly, test its face-to-face
seal, wear it in normal air for a familiarity period, and wear it in a test atmosphere.
4. A regular maintenance program must be instituted including cleaning, inspecting, and testing of
all respiratory equipment. Respirators used for emergency response must be inspected after
each use and at least monthly to assure that they are in satisfactory working condition. A
written record of inspection must be maintained.
5. Distribution areas for equipment used in emergencies must be readily accessible to employees.
Need and Requirements for SCBA
A positive-pressure self-contained breathing apparatus (SCBA) offers the best protection to
employees involved in controlling emergency situations. It must have a minimum service life
rating of at least 30 minutes. Conditions that require a positive-pressure SCBA include the
1. Leaking cylinders or containers, smoke from chemical fires, or chemical spills that indicate
high potential for exposure to toxic substances.
2. Atmospheres with unknown contaminants or unknown contaminant concentrations, confined
spaces that may contain toxic substances, or oxygen-deficient atmospheres.
Permit-required Confined Space Entry
Emergency situations may involve entering confined spaces to rescue employees who are
overcome by toxic compounds or who lack oxygen. These permit-required confined spaces include
tanks, vaults, pits, sewers, pipelines, and vessels. Entry into permit-required confined spaces can
expose the employee to a variety of hazards, including toxic gases, explosive atmospheres, oxygen
deficiency, electrical hazards, and hazards created by mixers and impellers that have not been
deactivated and locked out. Personnel must never enter a permit-required confined space unless the
atmosphere has been tested for adequate oxygen, combustibility, and toxic substances. Conditions
in a permit-required confined space must be considered immediately dangerous to life and health
unless shown otherwise. If a permit-required confined space must be entered in an emergency, the
following precautions must be adhered to:
1. All lines containing inert, toxic, flammable, or corrosive materials must be disconnected or
blocked off before entry.
2. All impellers, agitators, or other moving equipment inside the vessel must be locked out.
3. Employees must wear appropriate personal protective equipment before entering the vessel.
Mandatory use of harnesses must be stressed.
4. Rescue procedures must be specifically designed for each entry. A trained stand-by person must
be present. This person should be assigned a fully charged, positive-pressure, self-contained
breathing apparatus with a full face piece. The stand-by person must maintain unobstructed
lifelines and communications to all workers within the permit-required confined space and be
prepared to summon rescue personnel if necessary. The stand-by person should not enter the
confined space until adequate assistance is present. While awaiting rescue personnel, the standby person may make a rescue attempt utilizing lifelines from outside the permit-required
confined space.
OSHA Reference
A more complete description of procedures to follow while working in confined spaces may be
found in the OSHA standard for permit-required confined spaces, 29 CFR 1910.145 and the
National Institute for Occupational Safety and Health (NIOSH) Publication Number 80-106,
Criteria for a Recommended Standard...Working in Confined Spaces.
In a major emergency, time is critical factor in minimizing injuries. Most small businesses do not
have a formal medical program, but they are required to have the following medical and first-aid
1. In the absence of an infirmary, clinic, or hospital in close proximity to the workplace that can
be used for treatment of all injured employees, the employer must ensure that a person or
persons are adequately trained to render first aid. The first aid is to begin within 3 to 4 minutes
of the incident if the injury is of a serious nature.
2. Where the eyes or body of any employee may be exposed to injurious corrosive materials, eye
washes or suitable equipment for quick drenching or flushing must be provided in the work
area for immediate emergency use. Employees must be trained to use the equipment.
3. The employer must ensure the ready availability of medical personnel for advice and
consultation on matters of employees' health. This does not mean that health care must be
provided, but rather that, if health problems develop in the workplace, medical help will be
available to resolve them.
To fulfill the above requirements, the following actions should be considered:
1. Survey the medical facilities near the place of business and make arrangements to handle
routine and emergency cases. A written emergency medical procedure should then be prepared
for handling accidents with minimum confusion.
2. If the business is located far from medical facilities, at least one and preferably more employees
on each shift must be adequately trained to render first aid. The American Red Cross, some
insurance carriers, local safety councils, fire departments, and others may be contacted for this
3. First-aid supplies should be provided for emergency use. This equipment should be ordered
through consultation with a physician.
4. Emergency phone numbers should be posted in conspicuous places near or on telephones.
5. Sufficient ambulance service should be available to handle any emergency. This requires
advance contact with ambulance services to ensure they become familiar with plant location,
access routes, and hospital locations.
During an emergency, it is often necessary to secure the area to prevent unauthorized access and to
protect vital records and equipment. An off-limits area must be established by cordoning off the
area with ropes and signs. It may be necessary to notify local law enforcement personnel or to
employ private security personnel to secure the area and prevent the entry of unauthorized
Certain records also may need to be protected, such as essential accounting files, legal documents,
and lists of employees' relatives to be notified in case of emergency. These records may be stored
in duplicate outside the plant or in protected secure locations within the plant.
Every employee needs to know details of the emergency action plan, including evacuation plans,
alarm systems, reporting procedures for personnel, shutdown procedures, and types of potential
emergencies. Drills should be held at random intervals, at least annually, and include, if possible,
outside police and fire authorities.
Training must be conducted initially, when new employees are hired, and at least annually.
Additional training is needed when new equipment, materials, or processes are introduced, when
procedures have been updated or revised, or when exercises show that employee performance is
Personal Protection
Employees exposed to accidental chemical splashes, falling objects, flying particles, unknown
atmospheres with inadequate oxygen or toxic gases, fires, live electrical wiring, or similar
emergencies need personal protective equipment, including:
Safety glasses, goggles, or face shields for eye protection.
Hard hats and safety shoes.
Properly selected and fitted respirators.
Whole body coverings, gloves, hoods, and boots.
Body protection for abnormal environmental conditions such as extreme temperatures.
Employers not near an infirmary, clinic, or hospital should have someone on-site trained in first
aid, have medical personnel readily available for advice and consultation, and develop written
emergency medical procedures.
It is essential that first aid supplies are available to the trained medical personnel, emergency
phone numbers are placed in conspicuous places near or on telephones, and prearranged ambulance
services for any emergency are available.
Tools are such a common part of our lives that it is difficult to remember that they may pose
hazards. All tools are manufactured with safety in mind but, tragically, a serious accident often
occurs before steps are taken to search out and avoid or eliminate tool-related hazards.
In the process of removing or avoiding the hazards, workers must learn to recognize the hazards
associated with the different types of tools and the safety precautions necessary to prevent those
Hand tools are non-powered. They include anything from axes to wrenches. The greatest hazards
posed by hand tools result from misuse and improper maintenance.
Some examples:
Using a screwdriver as a chisel may cause the tip of the screwdriver to break and fly,
hitting the user or other employees.
If a wooden handle on a tool such as a hammer or an axe is loose, splintered, or cracked,
the head of the tool may fly off and strike the user or another worker.
A wrench must not be used if its jaws are sprung, because it might slip.
Impact tools such as chisels, wedges, or drift pins are unsafe if they have mushroomed
heads. The heads might shatter on impact, sending sharp fragments flying.
The employer is responsible for the safe condition of tools and equipment used by employees but
the employees have the responsibility for properly using and maintaining tools.
Employers should caution employees that saw blades, knives, or other tools be directed away from
aisle areas and other employees working in close proximity. Knives and scissors must be sharp.
Dull tools can be more hazardous than sharp ones.
Appropriate personal protective equipment, e.g., safety goggles, gloves, etc., should be worn due to
hazards that may be encountered while using portable power tools and hand tools.
Safety requires that floors be kept as clean and dry as possible to prevent accidental slips with or
around dangerous hand tools.
Around flammable substances, sparks produced by iron and steel hand tools can be a dangerous
ignition source. Where this hazard exists, spark-resistant tools made from brass, plastic, aluminum,
or wood will provide for safety.
Power tools can be hazardous when improperly used. There are several types of power tools, based
on the power source they use: electric, pneumatic, liquid fuel, hydraulic, and powder-actuated.
Employees should be trained in the use of all tools - not just power tools. They should understand
the potential hazards as well as the safety precautions to prevent those hazards from occurring.
The following general precautions should be observed by power tool users:
Never carry a tool by the cord or hose.
Never yank the cord or the hose to disconnect it from the receptacle.
Keep cords and hoses away from heat, oil, and sharp edges.
Disconnect tools when not in use, before servicing, and when changing accessories such as
blades, bits and cutters.
All observers should be kept at a safe distance away from the work area.
Secure work with clamps or a vise, freeing both hands to operate the tool.
Avoid accidental starting. The worker should not hold a finger on the switch button while
carrying a plugged-in tool.
Tools should be maintained with care. They should be kept sharp and clean for the best
performance. Follow instructions in the user's manual for lubricating and changing
Be sure to keep good footing and maintain good balance.
The proper apparel should be worn. Loose clothing, ties, or jewelry can become caught in
moving parts.
All portable electric tools that are damaged shall be removed from use and tagged "Do Not
Hazardous moving parts of a power tool need to be safeguarded. For example, belts, gears, shafts,
pulleys, sprockets, spindles, drums, fly wheels, chains, or other reciprocating, rotating, or moving
parts of equipment must be guarded if such parts are exposed to contact by employees.
Guards, as necessary, should be provided to protect the operator and others from the following:
* point of operation,
* in-running nip points,
* rotating parts, and
* flying chips and sparks.
Safety guards must never be removed when a tool is being used. For example, portable circular
saws must be equipped with guards. An upper guard must cover the entire blade of the saw. A
retractable lower guard must cover the teeth of the saw, except when it makes contact with the
work material. The lower guard must automatically return to the covering position when the tool is
withdrawn from the work.
The following hand-held powered tools must be equipped with a momentary contact "on-off"
control switch: drills, tappers, fastener drivers, horizontal, vertical and angle grinders with wheels
larger than 2 inches in diameter, disc and belt sanders, reciprocating saws, saber saws, and other
similar tools. These tools also may be equipped with a lock-on control provided that turnoff can be
accomplished by a single motion of the same finger or fingers that turn it on.
The following hand-held powered tools may be equipped with only a positive "on-off" control
switch: platen sanders, disc sanders with discs 2 inches or less in diameter; grinders with wheels 2
inches or less in diameter; routers, planers, laminate trimmers, nibblers, shears, scroll saws and
jigsaws with blade shanks 1/4-inch wide or less.
Other hand-held powered tools such as circular saws having a blade diameter greater than 2 inches,
chain saws, and percussion tools without positive accessory holding means must be equipped with
a constant pressure switch that will shut off the power when the pressure is released.
Employees using electric tools must be aware of several dangers; the most serious is the possibility
of electrocution.
Among the chief hazards of electric-powered tools are burns and slight shocks, which can lead to
injuries or even heart failure. Under certain conditions, even a small amount of current can result in
fibrillation of the heart and eventual death. A shock also can cause the user to fall off a ladder or
other elevated work surface.
To protect the user from shock, tools must either have a three-wire cord with ground and be
grounded, be double insulated, or be powered by a low-voltage isolation transformer. Three-wire
cords contain two current-carrying conductors and a grounding conductor. One end of the
grounding conductor connects to the tool's metal housing. The other end is grounded through a
prong on the plug. Anytime an adapter is used to accommodate a two-hole receptacle, the adapter
wire must be attached to a known ground. The third prong should never be removed from the plug.
Double insulation is more convenient. The user and the tools are protected in two ways: by normal
insulation on the wires inside, and by a housing that cannot conduct electricity to the operator in the
event of a malfunction.
These general practices should be followed when using electric tools:
Electric tools should be operated within their design limitations.
Gloves and safety footwear are recommended during use of electric tools.
When not in use, tools should be stored in a dry place.
Electric tools should not be used in damp or wet locations.
Work areas should be well lighted.
Powered abrasive grinding, cutting, polishing, and wire buffing wheels create special safety
problems because they may throw off flying fragments.
Before an abrasive wheel is mounted, it should be inspected closely and sound- or ring-tested to be
sure that it is free from cracks or defects. To test, wheels should be tapped gently with a light nonmetallic instrument. If they sound cracked or dead, they could fly apart in operation and so must
not be used. A sound and undamaged wheel will give a clear metallic tone or "ring."
To prevent the wheel from cracking, the user should be sure it fits freely on the spindle. The
spindle nut must be tightened enough to hold the wheel in place, without distorting the flange.
Follow the manufacturer's recommendations. Care must be taken to assure that the spindle wheel
will not exceed the abrasive wheel specifications.
Due to the possibility of a wheel disintegrating (exploding) during start-up, the employee should
never stand directly in front of the wheel as it accelerates to full operating speed.
Portable grinding tools need to be equipped with safety guards to protect workers not only from the
moving wheel surface, but also from flying fragments in case of breakage.
In addition, when using a powered grinder:
Always use eye protection.
Turn off the power when not in use.
Never clamp a hand-held grinder in a vise.
Pneumatic tools are powered by compressed air and include chippers, drills, hammers, and sanders.
There are several dangers encountered in the use of pneumatic tools. The main one is the danger of
getting hit by one of the tool's attachments or by some kind of fastener the worker is using with the
tool. Eye protection is required and face protection is recommended for employees working with
pneumatic tools. Noise is another hazard. Working with noisy tools such as jackhammers requires
proper, effective use of hearing protection.
When using pneumatic tools, employees must check to see that they are fastened securely to the
hose to prevent them from becoming disconnected. A short wire or positive locking device
attaching the air hose to the tool will serve as an added safeguard.
A safety clip or retainer must be installed to prevent attachments, such as chisels on a chipping
hammer, from being unintentionally shot from the barrel. Screens must be set up to protect nearby
workers from being struck by flying fragments around chippers, riveting guns, staplers, or air drills.
Compressed air guns should never be pointed toward anyone. Users should never "dead-end" it
against themselves or anyone else.
Powder-actuated tools operate like a loaded gun and should be treated with the same respect and
precautions. In fact, they are so dangerous that they must be operated only by specially trained
Safety precautions to remember include the following:
These tools should not be used in an explosive or flammable atmosphere.
Before using the tool, the worker should inspect it to determine that it is clean, that all
moving parts operate freely, and that the barrel is free from obstructions.
The tool should never be pointed at anybody.
The tool should not be loaded unless it is to be used immediately. A loaded tool should not
be left unattended, especially where it would be available to unauthorized persons.
Hands should be kept clear of the barrel end.
To prevent the tool from firing accidentally, two separate motions are required for firing:
one to bring the tool into position, and another to pull the trigger. The tools must not be
able to operate until they are pressed against the work surface with a force of at least 5
pounds greater than the total weight of the tool.
If a powder-actuated tool misfires, the employee should wait at least 30 seconds, then try firing it
again. If it still will not fire, the user should wait another 30 seconds so that the faulty cartridge is
less likely to explode, than carefully remove the load. The bad cartridge should be put in water.
Suitable eye and face protection are essential when using a powder-actuated tool.
The muzzle end of the tool must have a protective shield or guard centered perpendicularly on the
barrel to confine any flying fragments or particles that might otherwise create a hazard when the
tool is fired. The tool must be designed so that it will not fire unless it has this kind of safety
All powder-actuated tools must be designed for varying powder charges so that the user can select
a powder level necessary to do the work without excessive force.
If the tool develops a defect during use it should be tagged and taken out of service immediately
until it is properly repaired.
When using powder-actuated tools to apply fasteners, there are some precautions to consider.
Fasteners must not be fired into material that would let them pass through to the other side. The
fastener must not be driven into materials like brick or concrete any closer than 3 inches to an edge
or corner. In steel, the fastener must not come any closer than one-half inch from a corner or edge.
Fasteners must not be driven into very hard or brittle materials, which might chip or splatter, or
make the fastener ricochet.
An alignment guide must be used when shooting a fastener into an existing hole. A fastener must
not be driven into a spalled area caused by an unsatisfactory fastening.
The fluid used in hydraulic power tools must be an approved fire-resistant fluid and must retain its
operating characteristics at the most extreme temperatures to which it will be exposed.
The manufacturer's recommended safe operating pressure for hoses, valves, pipes, filters, and other
fittings must not be exceeded.
All jacks - lever and ratchet jacks, screw jacks, and hydraulic jacks – must have a device that stops
them from jacking up too high. Also, the manufacturer's load limit must be permanently marked in
a prominent place on the jack and should not be exceeded.
A jack should never be used to support a lifted load. Once the load has been lifted, it must
immediately be blocked up.
Use wooden blocking under the base if necessary to make the jack level and secure. If the lift
surface is metal, place a 1-inch-thick hardwood block or equivalent between it and the metal jack
head to reduce the danger of slippage.
To set up a jack, make certain of the following:
The base rests on a firm level surface,
The jack is correctly centered,
The jack head bears against a level surface, and
The lift force is applied evenly.
Proper maintenance of jacks is essential for safety. All jacks must be inspected before each use and
lubricated regularly. If a jack is subjected to an abnormal load or shock, it should be thoroughly
examined to make sure it has not been damaged.
Hydraulic jacks exposed to freezing temperatures must be filled with an adequate antifreeze liquid.
Employees who use hand and power tools and who are exposed to the hazards of falling, flying,
abrasive and splashing objects, or exposed to harmful dusts, fumes, mists, vapors, or gases must be
provided with the particular personal equipment necessary to protect them from the hazard.
All hazards involved in the use of power tools can be prevented by following five basic safety
Keep all tools in good condition with regular maintenance.
Use the right tool for the job.
Examine each tool for damage before use.
Operate according to the manufacturer's instructions.
Provide and use the proper protective equipment.
Employees and employers have a responsibility to work together to establish safe working
procedures. If a hazardous situation is encountered, it should be brought to the attention of the
proper individual immediately.
Safety Hazard Information Bulletin on Bench Grinders from OSHA:
The Directorate of Technical Support issues Hazard Information Bulletins (HIB) as needed to
provide relevant information regarding unrecognized or misunderstood safety and health hazards,
inadequacies of materials, devices, techniques, and engineering controls. HIB's are initiated based
on information provided by the field staff, studies, reports and concerns expressed by safety and
health professionals, employers, and the public. Information is compiled based on a comprehensive
evaluation of available facts, literature and in coordination with appropriate parties. HIB's do not
necessarily reflect OSHA policy.
The Boston Regional Office has bought to our attention a potentially serious hazard existing with
an employer's use of a bench grinder equipped with abrasive wheels were rated at 3103 RPM and
the grinder motor was rated at 3450 RPM. The BR Tools bench grinder, Model BG-8, was
purchased with 8-inch TAI HWA Grinding Wheel Company Ltd. wheels already installed. Both
the grinder and the abrasive wheels were manufactured in Taiwan. The employer could not provide
information as to where the bench grinder was purchased. While this may be an isolated case of
mismatched abrasive wheels and bench grinder, it has not been possible to contact the
manufacturer to verify the same. Indeed, this grinder in the same configuration may have been
imported by various distributors nationwide.
1. Controlling hazards. Personal Protective Equipment (PPE) devices alone should not
be relied on to provide protection against hazards, but should be used in conjunction with
guards, engineering controls, and sound manufacturing practices.
2. Assessment and selection. It is necessary to consider certain general guidelines for
assessing the foot, head, eye and face, and hand hazard situations that exist in an
occupational or educational operation or process, and to match the protective devices to
the particular hazard. It should be the responsibility of the safety officer to exercise
common sense and appropriate expertise to accomplish these tasks.
3. Assessment guidelines. In order to assess the need for PPE the following steps should
be taken:
A. Survey. Conduct a walk-through survey of the areas in question. The purpose of
the survey is to identify sources of hazards to workers and co-workers.
Consideration should be given to the basic hazard categories:
Compression (roll-over)
Harmful dust
Light (optical) radiation
B. Sources. During the walk-through survey the safety officer should observe:
Sources of motion; i.e., machinery or processes where any movement of
tools, machine elements or particles could exist, or movement of personnel
that could result in collision with stationary objects;
Sources of high temperatures that could result in burns, eye injury or
ignition of protective equipment, etc.;
Types of chemical exposures;
Sources of harmful dust;
Sources of light radiation, i.e., welding, brazing, cutting, furnaces, heat
treating, high intensity lights, etc.;
Sources of falling objects or potential for dropping objects;
Sources of sharp objects, which might pierce the feet or cut the hands;
Sources of rolling or pinching objects that could crush the feet;
Layout of workplace and location of co-workers; and
10. Any electrical hazards…Injury/accident data should be reviewed to identify
problem areas.
C. Organize data. Following the walk-through survey, it is necessary to organize the
data and information for use in the assessment of hazards. The objective is to
prepare for an analysis of the hazards in the environment to enable proper
selection of protective equipment.
D. Analyze data. Having gathered and organized data on a workplace, an estimate
of the potential for injuries should be made. Each of the basic hazards (paragraph
3.a.) should be reviewed and a determination made as to the type, level of risk,
and seriousness of potential injury from each of the hazards found in the area.
The possibility of exposure to several hazards simultaneously should be
4. Selection guidelines. After completion of the procedures in paragraph 3, the general
procedure for selection of protective equipment is to:
A. Become familiar with the potential hazards and the type of protective equipment
that is available, and what it can do; i.e., splash protection, impact protection,
B. Compare the hazards associated with the environment; i.e., impact velocities,
masses, projectile shape, radiation intensities, with the capabilities of the
available protective equipment;
C. Select the protective equipment which ensures a level of protection greater than
the minimum required to protect employees from the hazards; and
D. Fit the user with the protective device and give instructions on care and use of
the PPE. It is very important that end users be made aware of all warning labels
for and limitations of their PPE.
5. Fitting the device. Careful consideration must be given to comfort and fit. PPE that
fits poorly will not afford the necessary protection. Continued wearing of the device is
more likely if it fits the wearer comfortably. Protective devices are generally available in
a variety of sizes. Care should be taken to ensure that the right size is selected.
6. Devices with adjustable features. Adjustments should be made on an individual basis
for a comfortable fit that will maintain the protective device in the proper position. Take
care fitting devices for eye protection against dust and chemical splash to ensure that the
devices are sealed to the face. Proper fitting of helmets is important to ensure that it will
not fall off during work operations. In some cases a chin strap may be necessary to keep
the helmet on an employee's head. (Chinstraps should break at a reasonably low force to
prevent a strangulation hazard). Follow manufacturer's instructions carefully.
7. Reassessment of hazards. It is the responsibility of the safety officer to reassess the
workplace hazard situation as necessary, by identifying and evaluating new equipment
and processes, reviewing accident records, and reevaluating the suitability of previously
selected PPE.
A. Care should be taken to recognize the possibility of multiple and simultaneous
exposure to a variety of hazards. Adequate protection against the highest level of
each of the hazards should be provided. Protective devices do not provide
unlimited protection.
B. Operations involving heat may also involve light radiation. As required by the
standard, protection from both hazards must be provided.
C. Face shields should only be worn over primary eye protection (spectacles or
D. As required by the standard, filter lenses must meet the requirements for shade
designations in 1910.133(a)(5). Tinted and shaded lenses are not filter lenses
unless they are marked or identified as such.
E. As required by the standard, persons whose vision requires the use of
prescription (Rx) lenses must wear either protective devices fitted with
prescription (Rx) lenses or protective devices designed to be worn over regular
prescription (Rx) eyewear.
Wearers of contact lenses must also wear appropriate eye and face protection
devices in a hazardous environment. It should be recognized that dusty and/or
chemical environments may represent an additional hazard to contact lens
G. Caution should be exercised in the use of metal frame protective devices in
electrical hazard areas.
H. Atmospheric conditions and the restricted ventilation of the protector can cause
lenses to fog. Frequent cleansing may be necessary.
Welding helmets or face shields should be used only over primary eye protection
(spectacles or goggles).
Spectacles without side-shields are available for frontal protection only, but are
not acceptable eye protection for the sources and operations listed for "impact."
K. Ventilation should be adequate, but well protected from splash entry. Eye and
face protection should be designed and used so that it provides both adequate
ventilation and protects the wearer from splash entry.
L. Protection from light radiation is directly related to filter lens density. See note
(4) . Select the darkest shade that allows task performance.
8. Selection guidelines for head protection. All head protection (helmets) is designed
to provide protection from impact and penetration hazards caused by falling objects.
Head protection is also available which provides protection from electric shock and burn.
When selecting head protection, knowledge of potential electrical hazards is important.
Class A helmets, in addition to impact and penetration resistance, provide electrical
protection from low-voltage conductors (they are proof tested to 2,200 volts). Class B
helmets, in addition to impact and penetration resistance, provide electrical protection
from high-voltage conductors (they are proof tested to 20,000 volts). Class C helmets
provide impact and penetration resistance (they are usually made of aluminum which
conducts electricity), and should not be used around electrical hazards.
Where falling object hazards are present, helmets must be worn. Some examples include:
working below other workers who are using tools and materials which could fall;
working around or under conveyor belts which are carrying parts or materials; working
below machinery or processes which might cause material or objects to fall; and working
on exposed energized conductors.
9. Selection guidelines for foot protection. Safety shoes and boots which meet the
ANSI Z41-1991 Standard provide both impact and compression protection. Where
necessary, safety shoes can be obtained which provide puncture protection. In some work
situations, metatarsal protection should be provided, and in other special situations
electrical conductive or insulating safety shoes would be appropriate.
Safety shoes or boots with impact protection would be required for carrying or handling
materials such as packages, objects, parts or heavy tools, which could be dropped; and,
for other activities where objects might fall onto the feet. Safety shoes or boots with
compression protection would be required for work activities involving skid trucks
(manual material handling carts) around bulk rolls (such as paper rolls) and around heavy
pipes, all of which could potentially roll over an employee's feet. Safety shoes or boots
with puncture protection would be required where sharp objects such as nails, wire, tacks,
screws, large staples, scrap metal etc., could be stepped on by employees causing a foot
10. Selection guidelines for hand protection. Gloves are often relied upon to prevent
cuts, abrasions, burns, and skin contact with chemicals that are capable of causing local
or systemic effects following dermal exposure. OSHA is unaware of any gloves that
provide protection against all potential hand hazards, and commonly available glove
materials provide only limited protection against many chemicals. Therefore, it is
important to select the most appropriate glove for a particular application and to
determine how long it can be worn, and whether it can be reused.
It is also important to know the performance characteristics of gloves relative to the
specific hazard anticipated; e.g., chemical hazards, cut hazards, flame hazards, etc. These
performance characteristics should be assessed by using standard test procedures. Before
purchasing gloves, the employer should request documentation from the manufacturer
that the gloves meet the appropriate test standard(s) for the hazard(s) anticipated.
A. Factors to be considered for glove selection in general include
As long as the performance characteristics are acceptable, in certain
circumstances, it may be more cost effective to regularly change cheaper
gloves than to reuse more expensive types; and,
The work activities of the employee should be studied to determine the
degree of dexterity required, the duration, frequency, and degree of exposure
of the hazard, and the physical stresses that will be applied.
B. With respect to selection of gloves for protection against chemical hazards
The toxic properties of the chemical(s) must be determined; in particular, the
ability of the chemical to cause local effects on the skin and/or to pass
through the skin and cause systemic effects;
Generally, any "chemical resistant" glove can be used for dry powders;
For mixtures and formulated products (unless specific test data are
available), a glove should be selected on the basis of the chemical
component with the shortest breakthrough time, since it is possible for
solvents to carry active ingredients through polymeric materials; and, .
11. Cleaning and maintenance. It is important that all PPE be kept clean and properly
maintained. Cleaning is particularly important for eye and face protection where dirty or
fogged lenses could impair vision.
For the purposes of compliance with 1910.132 (a) and (b), PPE should be inspected,
cleaned, and maintained at regular intervals so that the PPE provides the requisite
protection. It is also important to ensure that contaminated PPE, which cannot be
decontaminated, is disposed of in a manner that protects employees from exposure to
Nearly one million Americans have already lost some degree of sight to an eye injury.
With over 365,000 work-related eye injuries still occurring each year, Americans could
use a few tips on how to prevent eye injuries in the workplace!
1. ASSESS! Conduct a thorough analysis of plant operations. Inspect work areas,
access routes and equipment. Examine eye accident and injury reports. Identify
operations and areas that present eye hazards.
2. TEST! Uncorrected vision problems contribute to accidents. Incorporate vision
testing in your pre-placement and routine physical examinations of employees.
3. PROTECT! Select protective eyewear designed for a specific operation or hazard.
Protective eyewear must meet the current standards referenced by the Occupational
Safety and Health Act of 1970 and subsequent revisions.
4. PARTICIPATE! For maximum protection against eye injury, establish a 100 percent
mandatory program that requires eye protection throughout all operations areas of
your plant. Experience shows this kind of program prevents more injuries and is
easier to enforce that one limited to certain departments, areas or jobs.
5. FIT! Workers cannot be expected to use their protective eyewear unless it fits
properly and comfortably. To ensure the eyewear is satisfactory, have it fitted by an
eye care professional or someone trained to do this. Provide the means for
maintenance and require each worker to be responsible for his or her own eyewear.
6. PLAN FOR AN EMERGENCY! Establish first-aid procedures for eye injuries. Make
eyewash stations accessible, particularly where chemicals are used. Train employees
in basic first aid and identify those with more advanced first-aid training.
7. EDUCATE! Conduct ongoing educational programs to establish, maintain and
reinforce the need for protective eyewear. Add eye safety to your regular employee
education/training programs and include it as a large part of new employee
8. SUPPORT! Management support is a key ingredient in successful eye safety
programs. All management personnel should set an example by wearing protective
eyewear whenever and wherever required.
9. REVIEW! Continually review and, when necessary, revise your accident prevention
strategies. Aim for the elimination of all accidents and injuries.
10. PUT IT IN WRITING! When all elements of your safety program have been
established, put them in writing. Display a copy of the policy in areas frequented by
employees, and include a review of the policy in new employee orientation.
The primary basis of this standard is the National Fire Protection Association's publication NFPA
30, Flammable and Combustible Liquids Code. This standard applies to the handling, storage, and
use of flammable and combustible liquids with a flash point below 200oF. There are two primary
hazards associated with flammable and combustible liquids:
Explosion and fire. In order to prevent these hazards, this standard addresses the primary concerns
of design and construction, ventilation, ignition sources, and storage .
There are a number of definitions included in 1910.106. These definitions were derived from
consensus standards, and were not uniquely developed for OSHA regulations. Some of the more
important definitions are discussed below.
Aerosol shall mean a material, which is dispensed from its container as a mist, spray, or foam by a
propellant under pressure.
Approved shall mean approved or listed by a nationally recognized testing laboratory.
Boiling point shall mean the boiling point of a liquid at a pressure of 14.7 pounds per square inch
absolute (psia). This pressure is equivalent to 760 millimeters of mercury (760 mm Hg).
At temperatures above the boiling point, the pressure of the atmosphere can no longer hold the
liquid in the liquid state and bubbles begin to form. The lower the boiling point, the greater the
vapor pressure at normal ambient temperatures and consequently the greater the fire risk.
Container shall mean any can, barrel, or drum.
Closed container shall mean a container so sealed by means of a lid or other device that neither
liquid nor vapor will escape from it at ordinary temperatures.
Fire area shall mean an area of a building separated from the remainder of the building by
construction having a fire resistance of at least 1 hour and having all communicating openings
properly protected by an assembly having a fire resistance rating of at least 1 hour.
Flash point means the minimum temperature at which a liquid gives off vapor within a test vessel
in sufficient concentration to form an ignitable mixture with air near the surface of the liquid. The
flash point is normally an indication of susceptibility to ignition.
The flash point is determined by heating the liquid in test equipment and measuring the
temperature at which a flash will be obtained when a small flame is introduced in the vapor zone
above the surface of the liquid.
A standard closed container is used to determine the closed-cup flash point and a standard opensurface dish for the open-cup flash point temperature, as specified by the American Society for
Testing and Materials (ASTM). These methods are referenced in OSHA's 1910.106 standard.
Combustible liquid means any liquid having a flash point at or above 100oF (37.8oC).
Classes of Combustible Liquids
Class I Liquids
Class IA shall include liquids having flash points below 73°F (22.8°C) and having a boiling
point below 100°F (37.8°C).
Class IB shall include liquids having flash points below 73°F (22.8°C) and having a boiling
point at or above 100°F (37.8°C).
Class IC shall include liquids having flash points at or above 73°F (22.8°C) and below 100°F
Class II Liquids
Class II Liquids shall include those with flash points at or above 100°F (37.8°C) and below
140°F (60°C). Any mixture having components with flash points of 200°F (93.3°C) or higher,
the volume of which make up 99 percent or more of the total volume of the mixture are also
listed as Class II Liquids.
Class III Liquids
Class III liquids shall include those with flash points at or above 140°F (60°C). Class III liquids
are subdivided into two subclasses:
Class IIIA liquids shall include those with flash points at or above 140°F (60°C) and below
200°F (93.3°C). Any mixture having components with flash points of 200°F (93.3°C), or higher,
the total volume of which make up 99 percent or more of the total volume of the mixture are
classed as Class IIIA.
Class IIIB liquids shall include those with flash points at or above 200°F (93.3°C). This section
does not regulate Class IIIB liquids. Where the term "Class III liquids" is used in this section, it
shall mean only Class IIIA liquids.
When a combustible liquid is heated to within 30°F (16.7°C) of its flash point, it shall be
handled in accordance with the requirements for the next lower class of liquids.
Flammable liquid means any liquid having a flash point below 100°F (37.8°C) or higher. The total
of which make up 99 percent or more of the total volume of the mixture. Flammable liquids shall
be known as Class I liquids.
It should be mentioned that flash point was selected as the basis for classification of flammable and
combustible liquids because it is directly related to a liquid's ability to generate vapor, i.e., its
volatility. Since it is the vapor of the liquid, not the liquid itself that burns vapor generation
becomes the primary factor in determining the fire hazard. The expression "low flash - high
hazard" applies. Liquids having flash points below ambient storage temperatures generally display
a rapid rate of flame spread over the surface of the liquid, since it is not necessary for the heat of
the fire to expend its energy in heating the liquid to generate more vapor.
Portable tank shall mean a closed container having a liquid capacity over 60 U.S. gallons and not
intended for fixed installation.
Safety can shall mean an approved container, of not more than 5 gallons capacity, having a springclosing lid and spout cover and so designed that it will safely relieve internal pressure when
subjected to fire exposure.
Vapor pressure shall mean the pressure, measured in pounds per square inch (absolute) exerted by a
volatile liquid as determined by the Standard Method of Test for Vapor Pressure of Petroleum
Products (Reid Method), American Society for Testing and Materials ASTM D323-68. Vapor
pressure is a measure of a liquid's propensity to evaporate. The higher the vapor pressure, the more
volatile the liquid and, thus, the more readily the liquid gives off vapors.
Ventilation as specified in this section is for the prevention of fire and explosion. It is considered
adequate if it is sufficient to prevent accumulation of significant quantities of vapor-air mixtures in
concentration over one-fourth of the lower flammable limit.
When vapors of a flammable or combustible liquid are mixed with air in the proper proportions in
the presence of a source of ignition, rapid combustion or an explosion can occur. The proper
proportion is called the flammable range and is also often referred to as the explosive range. The
flammable range includes all concentrations of flammable vapor or gas in air, in which a flash will
occur or a flame will travel if the mixture is ignited. There is a minimum concentration of vapor or
gas in air below which propagation of flame does not occur on contact with a source of ignition.
There is also a maximum proportion of vapor in air above which propagation of flame does not
occur. These boundary-line mixtures of vapor with air are known as the lower and upper flammable
or explosive limits (LEL or UEL) respectively, and they are usually expressed in terms of
percentage by volume of vapor in air.
In popular jargon, a vapor/air mixture below the flammable limit is too "lean" to burn or explode,
and a mixture above the upper flammable limit is too "rich" to burn or explode. No attempt is made
to differentiate between the terms flammable and explosive as applied to the lower and upper limits
of flammability.
This section applies only to the storage of flammable or combustible liquids in drums or other
containers (including flammable aerosols) not exceeding 60 gallons individual capacity and
portable tanks of less than 660 gallon individual capacity. A portable tank is a closed container,
which has a liquid capacity of over 60 gallons and is not intended for fixed installations.
This section does not apply to the following:
Storage of containers in bulk plants, service stations, refineries, chemical plants, and
Class I or Class II liquids in the fuel tanks of a motor vehicle, aircraft, boat, or portable or
stationary engine;
Flammable or combustible paints, oils, varnishes, and similar mixtures used for painting or
maintenance when not kept for a period in excess of 30 days;
Beverages when packed in individual containers not exceeding 1 gallon in size.
Only approved containers and portable tanks may be used to store flammable and combustible
liquids. Metal containers and portable tanks meeting the requirements of the Department of
Transportation (DOT) (49 CFR 178) are deemed acceptable when containing products authorized
by the DOT (49 CFR 173).
The latest version of NFPA 30, Flammable and Combustible Liquids Code indicates that certain
petroleum products may be safely stored within plastic containers if the terms and conditions of the
following specifications are met:
(a) ANSI/ASTM D 3435-80, Plastic Containers (Jerry Cans) for Petroleum Products.
(b) ASTM F 852-86, Standard for Portable Gasoline Containers for Consumer Use.
(c) ASTM F 976-86, Standard for Portable Kerosene Containers for Consumer Use.
(d) ANSI/UL 1313-83, Nonmetallic Safety Cans for Petroleum Products.
This standard also requires portable tanks to have provision for emergency venting. Top-mounted
emergency vents must be capable of limiting internal pressure under fire exposure conditions to 10
psig or 30 percent of the bursting pressure of the tank, whichever is greater. Portable tanks are also
required to have at least one pressure-activated vent with a minimum capacity of 6,000 cubic feet
of free air at 14.7 psia and 60°F. These vents must be set to open at not less than 5 psig. If fusible
vents are used, they shall be actuated by elements that operate at a temperature not exceeding
Maximum allowable sizes of various types of containers and portable tanks are specified based on
the class of flammable and combustible liquid they contain.
Not more than 60 gallons of Class I and/or Class II liquids, or not more than 120 gallons of Class
III liquids may be stored in an individual cabinet.
This standard permits both metal and wooden storage cabinets. Storage cabinets shall be designed
and constructed to limit the internal temperature to not more than 325°F when subjected to a
standardized 10-minute fire test. All joints and seams shall remain tight and the door shall remain
securely closed during the fire test. Storage cabinets shall be conspicuously labeled, "Flammable Keep Fire Away."
The bottom, top, door, and sides of metal cabinets shall be at least No. 18 gage sheet metal and
double walled with 11/2-inch air space. The door shall be provided with a three-point lock, and the
door sill shall be raised at least 2 inches above the bottom of the cabinet.
Flammable or combustible liquids, including stock for sale, shall not be stored so as to limit use of
exits, stairways, or areas normally used for the safe egress of people.
Office Occupancies
Storage shall be prohibited except that which is required for maintenance and operation of
equipment. Such storage shall be kept in closed metal containers stored in a storage cabinet or in
safety cans or in an inside storage room not having a door that opens into that portion of the
building used by the public.
General Purpose Public Warehouses
There are tables in the standard summarizing the storage requirements applicable to "General
Purpose Public Warehouses." These tables refer to indoor storage of flammable and combustible
liquids which are confined in containers and portable tanks. Storage of incompatible materials that
create a fire exposure (e.g., oxidizers, water-reactive chemicals, certain acids and other chemicals)
is not permitted.
Warehouses or Storage Buildings
The last type of inside storage covered by this paragraph addresses storage in "warehouses or
storage buildings." These structures are sometimes referred to as outside storage rooms. Practically
any quantity of flammable and combustible liquid can be stored in these buildings provided that
they are stored in a configuration consistent with the tables in this paragraph.
Containers in piles shall be separated by pallets or dunnage where necessary to provide stability
and to prevent excessive stress on container walls.
Stored material shall not be piled within 3 feet of beams or girders and shall be at least 3 feet below
sprinkler deflectors or discharge orifices of water spray, or other fire protection equipment.
Aisles of at least 3 feet in width shall be maintained to access doors, windows or standpipe
Requirements covering "storage outside buildings" are summarized in tables in this paragraph.
Associated requirements are given for storage adjacent to buildings. Also included are
requirements involving controls for diversion of spills away from buildings and security measures
for protection against trespassing and tampering. Certain housekeeping requirements are given
which relate to control of weeds, debris and accumulation of unnecessary combustibles.
Fire Control
Suitable fire control devices, such as small hose or portable fire extinguishers, shall be available at
locations where flammable or combustible liquids are stored. At least one portable fire extinguisher
having a rating of not less than 12-B units shall be located:
Outside of, but not more than 10 feet from, the door opening into any room used for
storage; and
Not less than 10 feet, nor more than 25 feet, from any Class I or Class II liquid storage area
located outside of a storage room but inside a building.
The reason for requiring that portable fire extinguishers be located a distance away from the storage
room is that fires involving Class I and Class II flammable liquids are likely to escalate rapidly. If
the fire is too close to the storage area, it may be impossible to get to it once the fire has started.
Open flames and smoking shall not be permitted in flammable or combustible liquid storage areas.
Materials, which react with water, shall not be stored in the same room with flammable or
combustible liquids. Many flammable and combustible liquid storage areas are protected by
automatic sprinkler or water spray systems and hose lines. Consequently, any storage of waterreactive material in the storage area creates an unreasonable risk.
The flash point is the lowest temperature at which a flammable liquid will give off enough vapors
to form an ignitable mixture with the air above the surface of the liquid or within its container.
The lower flammable limit the percentage of vapor in the air below, which a fire can't occur
because there isn't enough fuel: the mixture is said to be too lean.
The upper flammable limit is the percentage of vapor in the air above which there isn't enough air
for a fire: the mixture is said to be too rich.
Vapor density is the weight of a flammable vapor compared to air. (Air =1). Vapors with a high
density are more dangerous and require better ventilation because they tend to flow along the floor
and collect in low spots.
The Permissible Exposure Limit (PE) of the vapor according to OSHA standards is expressed in
parts of vapor per million parts of contaminated air. The PEL is listed because many of these
substances present inhalation as well as fire hazards.
EPA has defined waste as hazardous because of its general characteristics, or it may be specifically
listed by technical name. HPO also collects wastes that may not be defined by EPA as hazardous,
but present a significant enough hazard to warrant handling as a hazardous waste.
General Characteristics
Wastes exhibiting any of these characteristics are hazardous.
Liquids that have a flash point less than 140° F (60° C.), e.g., xylene
acetonitrile, ethanol, toluene.
b. Solids capable of causing fire by friction, absorption of
spontaneous chemical change and when ignited burn vigorously and
persistently to create a hazard, e.g., picric acid, sodium dithionite.
c. Flammable compressed gases, e.g., hydrogen, ethylene, methane.
d. Oxidizers; substances which yield oxygen readily to stimulate combustion,
e.g., potassium permanganate, sodium chlorate, sodium nitrate.
2. Corrosivity (EPA code D002)
a. Liquids capable of corroding steel at a specified rate and temperature.
b. Aqueous solutions with pH equal to or less than 2 or greater than 12.5.
3. Reactivity (EPA code D003)
Substances that react with water violently, or produce toxic gases or explosive mixtures
with water, e.g., potassium, sodium, and sodium hydride.
Substances that are normally unstable or explosive, e.g.,
Chemicals containing cyanide or sulfide that generate toxic gases when exposed to pH
between 2 and 12.5, e.g., potassium cyanide, sodium sulfide.
4. Toxicity (EPA code D series)
Materials that have certain heavy metals or organic constituents above
regulated levels, e.g., silver, cadmium, chloroform, etc.

Oil Spill Response
The large, environmentally devastating oil spills of recent years -- such as the 1989 on Valdez incident
-- have underscored the need for prompt, effective government and private sector response. Oil spills
kill and injure plants and wildlife, and can often upset delicate ecological balances.
This environmental damage can threaten public health and welfare by endangering drinking water
supplies and ruining commercial fishing industries. With oversight by the On-Scene Coordinator
(OSC), the party responsible for the spill may spend millions of dollars to clean up the spill, restore
damaged natural resources, and pay penalties. As many people know from news coverage of spills
such as the Exxon Valdez, the U.S. Coast Guard is in charge of response to coastal spills. What many
people do not realize, however, is that EPA responds to oil spills to inland waters (e.g., rivers, lakes)
and adjoining shorelines. Inland spills can be as catastrophic as the more publicized coastal incidents.
The 1988 collapse of an above-ground oil storage tank in Pennsylvania released almost one million
gallons of diesel fuel into the Monongahela and Ohio Rivers, disrupting water supplies, forcing the
closing of schools and businesses, and inflicting serious ecological damage.
Laws and Regulations
EPA carries out its oil spill response activities as part of its responsibilities under section 311 of the
Clean Water Act. Specifically, section 311 provides for oil spill reporting, response, enforcement,
and funding -- and for measures to prevent oil spills from happening in the first place. These Clean
Water Act provisions were expanded upon and strengthened by the Oil Pollution Act of 1990
(OPA). The oil spill regulations that EPA has issued to fulfill its Clean Water Act duties have two
basic purposes: preventing spills from occurring, and ensuring a quick, effective cleanup of spills
that do occur.
Laws for Oil Spill Responses: The Clean Water Act
Section 311 of the Clean Water Act was amended by the Oil Pollution Act of 1990 to require that EPA
and the Coast Guard direct responses to oil spills that pose a substantial threat to public health and
welfare. The Oil Pollution Act also added a requirement that vessels and fixed facilities prepare plans
to prevent oil spills and to respond to spills that do occur.
Other provisions of section 311 of the Clean Water Act authorize EPA and the Coast Guard to:
Establish criteria for notifying the Federal government of discharges of oil into
U.S. waters;
Direct and conduct responses to oil spills;
Assess civil and criminal penalties for violation of oil spill laws; and
Administer a Federal oil spill response fund.
Prevention: The Best Response
The easiest and simplest way to avoid the environmental and economic costs of oil spills is to keep
them from happening in the first place. The Agency's Spill Prevention, Control and Countermeasures
(SPCC) regulation requires certain non-transportation-related facilities (e.g., storage facilities,
refineries) that store oil to prepare plans for the prevention and containment of oil spills. The U.S.
Department of Transportation regulates transportation-related facilities (e.g., pipelines, shoreline
loading facilities for vessels). Under the Agency's SPCC program, EPA OSCs, States and Technical
Assistance Teams inspect hundreds of facilities each year. Inspectors examine the layout,
organization, and structure of the facility and review the facility's SPCC plan to ensure compliance
with the regulation.
Planning for an Oil Spill
Despite prevention efforts, oil spills do occur. Therefore, it is most important to be ready with a plan
for minimizing the size of the spill and the amount of damage it causes. The National Contingency
Plan requires that Federal, State and Local officials as well as responsible parties plan for and work
together to clean up spills quickly and effectively. Under the Clean Water Act, as amended by the
OPA, facility owners and operators must have specific plans for response to a worst-case spill from
their facilities. Periodically, EPA also inspects facilities' spill removal equipment. The OPA requires
EPA and other Federal, State and Local officials to develop spill response plans for every inland area
of the U.S. These Area Contingency Plans facilitate the coordination of response efforts when spills
do occur. The OPA planning and inspection requirements assure that both government and
responsible parties are prepared to respond effectively to dangerous spills.
When an Oil Spill Occurs
The Discharge of Oil Regulation (also known as the "sheen" rule under the Clean Water Act) states
that whenever an oil spill occurs in U.S. waters that causes a discoloration or sheen on the surface of a
body of water, the person in charge of the facility or vessel responsible for the spill must notify the
National Response Center immediately at (800) 424-8802. If the spill is in inland waters, the National
Response Center will relay the information by telephone to an EPA OSC in the appropriate EPA
Regional office so that the Agency can assess whether and how it should respond. EPA directs any
responses to inland spills that pose a substantial threat to the public health or welfare, and has the
authority to respond to any other discharges. Even where other State or Federal agencies assume
control of the response, EPA provides advice and monitors response efforts. OSCs consider and apply
a full range of resources and methods for responding to spills.
Mechanical methods -- booms, skimmers, and containers -- may be used to recover the spilled
oil and to store the oil until it can be disposed of or reused. Mechanical containment or recovery is the
most common type of response action.
Chemical treatments may be employed to coagulate the oil for easier collection, or to direct the
oil to a less sensitive location by dispersing it into tiny droplets. Biological techniques such as the
introduction of microbes or microbe nutrients may be used to promote the natural microbial
consumption and decomposition of oil.
The Agency maintains a list of chemical and biological products -- the National Contingency Plan
Product Schedule -- that may be approved and used on particular spills. The list provides data
available on the products, thus ensuring that responders have certain baseline information to use in
their decision making.
EPA and the Coast Guard seek to recover spill response costs and damages from responsible parties
whenever possible. When the party responsible for a spill cannot be determined or does not have the
funds to cover response costs, the costs may be paid from the Oil Spill Liability.
Trust Fund. Fund monies are supplied by a five-cent-per-barrel fee on domestic and imported oil. The
Fund provides up to $1 billion per incident for cleanup costs and other damages. An example of a
Federal response to an inland oil spill is provided next.
Getting Involved
EPA plays a vital role in protecting our environment, but this cannot be accomplished without
assistance and cooperation from the public. Some important responsibilities of local communities are
to notify the National Response Center ((800) 424-8802) of any emergency incidents, be prepared for
releases that do occur, assist with the response, and generally stay informed. The Agency works with
the public by informing local communities of emergency incidents and resulting response actions.
Informing the Community
The Agency responds to the public's need for information by answering questions directly,
making presentations, and preparing and distributing publications. The National Contingency Plan
describes specific requirements for community relations and public participation in emergency
responses to releases of oil and hazardous substances. In the case of removal actions at hazardous
waste sites, for example, EPA appoints a spokesperson who notifies the community of specific
response actions, answers any questions, and updates the residents on progress at the site. An
administrative record, or a repository of information on the site, must be established within 60 days. If
the removal action is expected to continue for more than 120 days, the spokesperson will interview
community groups to identify their concerns and prepare a community relations plan to address these
Taking Responsibility in Cleanup
In cleaning up oil spills or hazardous substance releases, EPA notifies the parties potentially
responsible for the release to involve them as appropriate in the process. Local governments also are
encouraged to participate in the response. Under the Superfund Amendments and Reauthorization Act
of 1986, the Agency established a reimbursement program to help local governments cope with
expenses that significantly exceed funds available for temporary emergency response measures.
Workshops and Publications
The Agency conducts workshops and seminars to keep Federal, State, and local regulators, the
regulated community, trade groups, and the general public informed about EPA regulations and
programs. EPA uses lectures, handout materials, question-and- answer sessions, hypothetical release
scenarios, and computer demonstrations to convey important information.
EPA also prepares and distributes informational materials on releases of oil and hazardous substances,
cleanup efforts, and related issues to a wide variety of audiences. Some examples include journal
articles and question-and-answer booklets for the regulated community. EPA headquarters and field
personnel are kept up-to-date through bulletins on statutory requirements, response activities, and new
regulations and policies. If you would like more information on how EPA's emergency response
program works, please contact your EPA Regional office.

OSHA's 1986 asbestos rule included methods of suppression and collection of asbestos
dust and debris in brake and clutch repair operations. These were described in a nonmandatory appendix to the rule.
In response to a court remand of the 1986 rule, OSHA reconsidered certain provisions
and issued a revised asbestos rule on August 10, 1994. In the final standard, 29 CFR
1910.1001, Occupational Exposure to Asbestos, Appendix F:
OSHA lists two "preferred methods," the wet-brush recycle method and the
enclosure/HEPA vacuum system. A more recent change is that OSHA will accept
the use of spray/solvent cans when performing brake and clutch repair as full
compliance with the standard when simple clean-up procedures.
Welding Operations in an MANUFACTURING Environment
Conditions That Directly Effect Safety & Health in Welding Operations
Welding and cutting are "hot" processes; the fires and explosions are ever present.
Fire prevention is a major priority.
Four acceptable options for preventing fires and explosions caused by welding & cutting processes
Move the combustibles away from the welding
Move the welding away from the combustibles
Protect the combustibles from exposure
Separate the Combustibles From the Welding/Cutting Operation
Welding and cutting operations must be separated from combustibles by at least 35 feet.
This distance should be multiplied by at least 2.5 when the welding/cutting operation is
suspended over combustibles.
Protect the Combustibles From Welding/Cutting Operations
This option should only be chosen when the welding/cutting operation and the
combustibles cannot be adequately separated.
Protective barriers may include fire blankets, steel partitions, or other types of covers.
A FIRE WATCHER should also be present.
Duties and Specifications for the Fire Watcher
The Fire Watcher must be adequately trained to operate fire fighting equipment.
The Fire Watcher must be properly instructed on what to do if a fire occurs.
The Fire Watcher must remain for at least 1/2 hour after the job has been completed.
Special Notes for Preventing Fire & Explosions due to Welding or Cutting
Find out what's on the other side of the wall.
Watch out for closed containers.
Don't expose electric lines or hydraulic lines to heat.
Unsafe Equipment Promotes Occupational Accidents & Illnesses
Check the equipment thoroughly and often, especially after it has been moved.
Check hoses, regulators, valves, power conductors, leads, transformers, and restraining
• Keep the equipment clean and free of rust, moisture, and petroleum products.
Safety Means Communicating
Coordination of efforts promotes safety.
Workers who are assigned tasks near welding/cutting processes must know how to avoid
the associated risks.
Welders must communicate with one another on safety matters such as ground
connections, material stresses, etc.
Occupational Illnesses
Illnesses may be either acute or chronic
Illnesses suffered by welders/cutters are generally caused by the hot process or a result of
working in confined spaces
You must know and understand the hazards associated with the materials to which the
welder/cutter is exposed
Compile ALL the MSDS
An MSDS must be available AT THE JOB SITE for every material and found on that site
Each welder must be informed on the hazards associated with the materials and substances
Each welder must be adequately protected from injury that may result from exposure to the
job hazards Some MSDS Include:
Welding rods, fluxes, gases, and resins
Base metals which are fabricated by the welding processes
Coatings found on the base metal or close to the welding processes
Watch out for chlorinated solvents such as: lead, nickel, chromium, cadmium, fluorine, tin,
brass/bronze, copper, zinc, aluminum, vanadium, selenium, and silver.
Inherent Hazards Associated With Welding and Cutting
UV and IR light sources (lens shade)
Thermal burns (gloves, shoes, hood)
Heat stress (water, breaks, scheduling)
Cuts (materials handling gloves)
Trip/Fall injuries (housekeeping)
"Struck by" injuries (shoes, hard hats)
Those to which any other worker may be exposed
You MUST be Familiar With and Expect Variations in the WORKPLACE
The nature and degree of exposure to hazards changes from day to day
This is especially true in the construction industry
The only way you can keep up with new developments is to go into the work area.
REMEMBER: no two jobs are the same.
Fire extinguishers and extinguishing material has been around for a long time. You've seen them
everywhere, they're very useful and have saved many lives. But not everyone understands them or
know how to use them. If you were experiencing a flammable liquid fire, what type of
extinguisher would be necessary to extinguish the fire? Water? Would you use an ABC type
extinguisher or an ABCD type extinguisher?
Always remember that life safety is much more important than property. If you can't extinguish a
fire safely, call the fire department and let them handle the situation. In the event of a small fire,
call the fire department anyway, because small fires can quickly get out of hand and seconds count
in the fire fighting business. Fire extinguishers are not designed to fight a large or spreading fire
and even against small fires, extinguishers are useful only under the right conditions. We know
that everyone takes fire extinguishers for granted because they aren't used on a frequent basis. You
don't pay much attention to them because you know they'll be there in case of an emergency.
First of all, extinguishers must be inspected at least monthly. Be sure to retain these inspection
records in your files. Inspect extinguishers to make sure they're clean and in serviceable condition,
the pin is sealed on the handle to indicate it hasn't been used and of course, to check the correct
pressure, if your extinguisher has a pressure gauge. Remember that once an extinguisher has been
used, if only for a second..... it must be completely serviced and recharged.
Extinguishers get damaged and may not work when the need arises, so check for visible damage to
the container and the handle. You're also checking to make sure the extinguisher is located in its
proper place. In the event an extinguisher is used or found to be defective, most organizations have
extra extinguishers, to replace the damaged or defective extinguisher while it’s being repaired or
serviced. Inspect all extinguishers at least monthly. Once a year, fire extinguishers must be
inspected and service by an authorized service company. After the extinguishers have been
inspected and serviced, the servicing company will issue a service tag. This tag is good for one
year. During your monthly inspections, check these service tags, to make sure this tag is on the
extinguisher and it’s current. If the tag is over a year old, it needs to be re-serviced.
Fire extinguishers come in all shapes and sizes, but you're probably most familiar with the red
extinguishers. Many years ago, fire extinguishers looked like this. Actually, it was a bottle of
water that was thrown at the fire. The bottle broke and hopefully cooled the fire. Later, evolved a
water and acid solution extinguisher. This type of extinguisher was activated by turning the
extinguisher upside down and the acid reacted with the water to build pressure and expel the
extinguishing agent. We don't use these anymore because they're old and when activated, they
have a tendency to explode when pressurized. If you have any of these types of extinguishers....
don’t use them, as they could be very dangerous when used.
Today, we have a variety of extinguishers, each designed to fight different types of fires. Most are
pressurized, with an inert gas, that expels the extinguishing agent, such as dry chemical, carbon
dioxide, foam, water mists or other agents.
We use the word PASS to help you remember how to use an extinguisher. Pull the pin, Aim the
nozzle, Squeeze the handle and Sweep from side to side. Pass. Remember we said these
extinguishers were pressurized. This means you need to hold the extinguisher firmly, as the force
of the expelled gas can be fairly strong, so hang onto the extinguisher if you're going to pull the pin
and squeeze the handle. Also, if you’ve never used an extinguisher, the noise of the expelling gas
can startle you, so be prepared.
Combustion is created by interaction of three basic elements. Heat or ignition, Oxygen and Fuel.
We call it the fire triangle. To extinguish a fire, you have to interrupt one or more elements.
Therefore, to kill a fire, one or more of these elements must be denied. You can exclude oxygen
from the fire, remove the fuel on which the fire is feeding or lower the temperature. We have
different types of extinguishers for each type or classes of fire.
First, there’s CLASS A FIRES. Generally they have glowing embers as a by-product. A persons'
house on fire could be classified as a class 'A' fire. Wood, clothing, curtains, paper or similar
materials are considered Class A Fires. Water is the extinguishing agent on class 'a' fires, which
cools the temperature of the fire until it’s extinguished.
CLASS B FIRES include flammable liquids and gases, such as gasoline, oil, paints, grease,
acetylene and thinners. To extinguish a class B fire, the objective is to remove the oxygen from the
fire. Carbon dioxide, or CO2 extinguishing agents displace the oxygen of the fire. Here is a CO2
extinguisher in action. It puts the fire out very quickly. These extinguishers are filled with CO2
which is a non-flammable carbon dioxide gas under extreme pressure. You can recognize a CO2
extinguisher by it hard plastic or metal horn and lack of pressure gauge. The pressure in the
cylinder is so great that when you use it, bits of dry ice may shoot out the horn. CO2 extinguishes
the fire by displacing oxygen or taking away the oxygen element of the fire triangle. It is a clean
extinguishing agent and generally will not leave a residue on sensitive electronic or other
equipment. It is also non-conductive, which means it can be used for electrical fires. CO2 may be
ineffective on Class A fires, as it may not displace enough oxygen to successfully put out the fire.
Class ‘C' is for fires involving electricity. Motors, compressors, pumps, electrical tools, fuse
boxes, appliances and anything energized with electricity. You wouldn't want to use water on
electrical fires as the electrical shock hazard could be as damaging as the fire itself.
Class 'D' fires are those fires involving exotic metals, such as beryllium, sodium, titanium,
magnesium and other metals that can burn. Class 'd' extinguishers smother the fire with a dry
chemical to extinguish burning metals.
In most cases now, he most familiar type of extinguisher is the ABC type. Why is it called ABC?
Primarily because this extinguisher uses a dry chemical powder that extinguishes CLASS 'A',
There's another extinguishing agent called Halon, which is a clean, chemical extinguisher that's was
designed for computers, electronic equipment and other sensitive equipment. Halon is no longer
being used, and has been banned in the United States and other countries, due to the potential
damage to the environment by depleting the ozone. There are new extinguishers and systems that
will replace Halon, such as a “water-mist” type extinguishing agent. Water mist is non-toxic and
has no ozone depletion potential. Water mist is electrically non-conductive and enhances the
cooling and soaking characteristics of the agent. It is designed to replace Halon in health care
facilities, electronic equipment manufacturing and similar environments.
Good housekeeping is one of the most important parts of fire prevention. Clean, neat and
organized. Don't forget to keep closets, janitorial rooms and other equipment areas clean, neat and
Store flammable liquids in approved containers and don't leave paint cans, thinners or solvents
around your work area. Flammables and combustibles should be kept in safety containers and
properly stored when not in use.
Check your equipment, especially your electrical cords, tools, plugs and receptacles, to make sure
they're in serviceable condition.
If you work with flammable liquids, pay attention to spark producing tools, electrical motors and
other items that can ignite flammable vapors.
Do you know what makes a safety container for flammable liquids? An approved flammable liquid
container has a spring loaded lid, to prevent spills, but will allow the liquid in the container to
expand by slightly releasing the lid enough for small amounts of vapors to escape. It allows
excess pressure to escape, but won't spill the liquid. Gasoline cans without spring loaded lids,
cannot breath, therefore expansion of the liquid can cause the can to burst. Perhaps the most
important part of a safety container is the flame arrestor. It's a mesh screen inside the container that
looks like a filter. It's designed to prevent flames from returning inside the container causing an
explosion. This type of container, that is sold in almost any hardware or gas station today does not
have a flame arrestor. If you're pouring a flammable liquid out of this type of container and a spark
or other ignition source causes a fire, the flame can be sucked back into the can causing a violent
explosion. Now you know the difference in a safety container and a potential bomb. We didn't
even mention bonding and grounding of flammable liquid containers to reduce the potential of
explosion due to static electricity. That information comes in another program.
How about those shop rags, oily clothing and other fire hazards? Be sure to put soiled rags into
safety waste cans. Metal cans with metal lids. You can create spontaneous combustion by leaving
greasy rags sitting in a corner or stored in a container other than a metal container that has a metal
We could continue with fire prevention, such as not blocking exits with materials, smoking only in
authorized areas, emptying trash daily, knowing where exits are located and keeping your
equipment clean to prevent residue buildup and fire potential, but we don't have time to cover these
subjects in this program. They're common sense items and the importance of preventing fires,
rather than extinguishing them is well known.
Fire and Smoke Hazards
Life safety is paramount.... your life and the lives of others. Don’t take chances. If you’re not sure
if you can extinguish a fire safely, leave the area and close the door behind you, to keep the fire
from spreading. Understand that smoke from any type of fire kills more people than the actual fire.
Never try to extinguish a fire if smoke presents any hazard. The fumes and gases of smoke are
very toxic and can kill you.
When fighting a fire with an extinguisher, always keep your back toward an available escape route.
Remember the word PASS. This word is a reminder to: Pull the pin, Aim the nozzle, Squeeze the
handle and Sweep from side to side.
Remove the extinguisher from its mount and take it to the fire. Pull the pin, then aim the
extinguisher nozzle towards the base of the fire, standing approximately 6 to 10 feet from the fire.
Then squeeze the handle. If you stand too close to the fire and squeeze the handle, the force of the
pressurized gas and extinguishing material could actually spread the flames. Stand away,...... aim
the nozzle towards the base of the flame, .... squeeze the handle,..... sweeping from side to side......
then move closer.
After the fire is out, check to make sure it's really out. Don’t leave the area until you have verified
that a fire will not re-ignite. Many times, fires start up again after you think they're out. That's
another reason for calling the fire department. If you are successful in extinguishing the fire, the
fire department professionals can double check to make sure it's fully extinguished and they're
happier if you already have the fire extinguished. They get real upset if you don't call them until
the fire gets out of hand. It's also a good idea to communicate and train with your local fire
department. This gives them better training and familiarity at your facilities, in the event of an
emergency. Fire extinguisher service vendors often provide hands on training with the
extinguishers, as well.
Don't be afraid to let your supervisor know you never have used an extinguisher. Most people
haven't used an extinguisher and extinguishing a fire with an extinguisher does require a little
training and practice.
It’s important to remember the classes of fire and why certain extinguishing agents work better on
certain types of fires. Remember we stated that some extinguishing agents, such as water, cools the
temperature of the fire until it’s extinguished. Some agents, such as carbon dioxide removes
oxygen from the fire. This is important because if you’re in an area where large amounts of carbon
dioxide is used to extinguish a fire......... there will be insufficient oxygen for you to breathe. There
are other fire suppression systems, such as a foam extinguishing system. You can see here, a
gasoline loading dock’s foam system was activated and it acts like a sprinkler system, covering the
entire area with foam. There are dry chemical and CO2 systems, commonly used in kitchens, to
automatically suppress a fire. You should be familiar with any automatic systems in your area and
know how they work and what type of extinguishing agent is used.
Knowing and understanding classes of fires, types of extinguishing agents and how to use fire
extinguishers is extremely important. This knowledge can save your life in case of emergency.
Remember that life safety is paramount. Never try to extinguish a fire where your life or the lives
of others are in jeopardy. Get out and leave the fire fighting to the professionals. Keep calm and
put your emergency plan in action. The life you save may be your own.
Thousands of accidents occur throughout the United States every day. The failure of people,
equipment, supplies, or surroundings to behave or react as expected causes most of the accidents.
Accident investigations determine how and why these failures occur. By using the information
gained through an investigation, a similar or perhaps more disastrous accident may be prevented.
Conduct accident investigations with accident prevention in mind. Investigations are NOT to place
An accident is any unplanned event that results in personal injury or in property damage. When the
personal injury requires little or no treatment, it is minor. If it results in a fatality or in a permanent
total, permanent partial, or temporary total (lost-time) disability, it is serious. Similarly, property
damage may be minor or serious. Investigate all accidents regardless of the extent of injury or
Accidents are part of a broad group of events that adversely affect the completion of a task. These
events are incidents. For simplicity, the procedures discussed in later sections refer only to
accidents. They are, however, also applicable to incidents. This discussion introduces the reader to
basic accident investigation procedures and describes accident analysis techniques.
Accidents are usually complex. An accident may have 10 or more events that can be causes. A
detailed analysis of an accident will normally reveal three cause levels: basic, indirect, and direct.
At the lowest level, an accident results only when a person or object receives an amount of energy
or hazardous material that cannot be absorbed safely. This energy or hazardous material is the
DIRECT CAUSE of the accident. The direct cause is usually the result of one or more unsafe acts
or unsafe conditions, or both. Unsafe acts and conditions are the INDIRECT CAUSES or
symptoms. In turn, indirect causes are usually traceable to poor management policies and decisions,
or to personal or environmental factors. These are the BASIC CAUSES.
In spite of their complexity, most accidents are preventable by eliminating one or more causes.
Accident investigations determine not only what happened, but also how and why. The information
gained from these investigations can prevent recurrence of similar or perhaps more disastrous
accidents. Accident investigators are interested in each event as well as in the sequence of events
that led to an accident. The accident type is also important to the investigator. The recurrence of
accidents of a particular type or those with common causes shows areas needing special accident
prevention emphasis.
The actual procedures used in a particular investigation depend on the nature and results of the
accident. The agency having jurisdiction over the location determines the administrative
procedures. In general, responsible officials will appoint an individual to be in charge of the
investigation. The investigator uses most of the following steps:
1. Define the scope of the investigation.
2. Select the investigators. Assign specific tasks to each (preferably in writing).
3. Present a preliminary briefing to the investigating team, including:
Description of the accident, with damage estimates.
Normal operating procedures.
Maps (local and general).
Location of the accident site.
List of witnesses.
Events that preceded the accident.
4. Visit the accident site to get updated information.
5. Inspect the accident site.
Secure the area. Do not disturb the scene unless a hazard exists.
Prepare the necessary sketches and photographs. Label each carefully and keep accurate
6. Interview each victim and witness. Also interview those who were present before the accident
and those who arrived at the site shortly after the accident. Keep accurate records of each
interview. Use a tape recorder if desired and if approved.
7. Determine
What was not normal before the accident.
Where the abnormality occurred.
When it was first noted.
How it occurred. Analyze the data gathered.
8. Analyze the data obtained in step 7. Repeat any of the prior steps, if necessary.
9. Determine
Why did the accident occur?
A likely sequence of events and probable causes (direct, indirect, basic).
Alternative sequences.
10. Check each sequence against the data from step 7.
11. Determine the most likely sequence of events and the most probable causes.
12. Conduct a post-investigation briefing.
13. Prepare a summary report, including the recommended actions to prevent a recurrence.
Distribute the report according to applicable instructions.
An investigation is not complete until all data are analyzed and a final report is completed. In
practice, the investigative work, data analysis, and report preparation proceed simultaneously over
much of the time spent on the investigation.
Gather evidence from many sources during an investigation. Get information from witnesses and
reports as well as by observation. Interview witnesses as soon as possible after an accident. Inspect
the accident site before any changes occur. Take photographs and make sketches of the accident
scene. Record all pertinent data on maps. Get copies of all reports. Documents containing normal
operating procedures, flow diagrams, maintenance charts, or reports of difficulties or abnormalities
are particularly useful. Keep complete and accurate notes in a bound notebook. Record pre-accident
conditions, the accident sequence, and post-accident conditions. In addition, document the location
of victims, witnesses, machinery, energy sources, and hazardous materials.
In some investigations, a particular physical or chemical law, principle, or property may explain a
sequence of events. Include laws in the notes taken during the investigation or in the later analysis
of data. In addition, gather data during the investigation that may lend itself to analysis by these
laws, principles, or properties. An appendix in the final report can include an extended discussion.
In general, experienced personnel should conduct interviews. If possible, the team assigned to this
task should include an individual with a legal background. In conducting interviews, the team
1. Appoint a speaker for the group.
2. Get preliminary statements as soon as possible from all witnesses.
3. Locate the position of each witness on a master chart (including the direction of view).
4. Arrange for a convenient time and place to talk to each witness.
5. Explain the purpose of the investigation (accident prevention) and put each witness at ease.
6. Listen, let each witness speak freely, and be courteous and considerate.
7. Take notes without distracting the witness. Use a tape recorder only with consent of the
8. Use sketches and diagrams to help the witness.
9. Emphasize areas of direct observation. Label hearsay accordingly.
10. Be sincere and do not argue with the witness.
11. Record the exact words used by the witness to describe each observation. Do not “put words
into a witness’ mouth.”
12. Word each question carefully and be sure the witness understands.
13. List the qualifications of each witness (name, address, occupation, years of experience, etc.).
14. Supply each witness with a copy of his or her statements. Signed statements are desirable.
After interviewing all witnesses, the team should analyze each witness’ statement. They may wish
to re-interview one or more witnesses to confirm or clarify key points. While there may be
inconsistencies in witnesses’ statements, investigators should assemble the available testimony into
a logical order. Analyze this information along with data from the accident site.
Not all people react in the same manner to a particular stimulus. For example, a witness within
close proximity to the accident may have an entirely different story from one who saw it at a
distance. Some witnesses may also change their stories after they have discussed it with others. The
reason for the change may be additional clues.
A witness who has had a traumatic experience may not be able to recall the details of the accident.
A witness who has a vested interest in the results of the investigation may offer biased testimony.
Finally, eyesight, hearing, reaction time, and the general condition of each witness may affect his
or her powers of observation. A witness may omit entire sequences because of a failure to observe
them or because their importance was not realized.
Accidents represent problems that must be solved through investigations. Several formal
procedures solve problems of any degree of complexity. This section discusses two of the most
common procedures: Change Analysis and Job Safety Analysis.
Change Analysis
As its name implies, this technique emphasizes change. To solve a problem, an investigator must
look for deviations from the norm. Consider all problems to result from some unanticipated change.
Make an analysis of the change to determine its causes. Use the following steps in this method:
1. Define the problem (What happened?).
2. Establish the norm (What should have happened?).
3. Identify, locate, and describe the change (What, where, when, to what extent).
4. Specify what was and what was not affected.
5. Identify the distinctive features of the change.
6. List the possible causes.
7. Select the most likely causes.
Job Safety Analysis
Job safety analysis (JSA) is part of many existing accident prevention programs. In general, JSA
breaks a job into basic steps, and identifies the hazards associated with each step. The JSA also
prescribes controls for each hazard. A JSA is a chart listing these steps, hazards, and controls.
Review the JSA during the investigation if a JSA has been conducted for the job involved in an
accident. Perform a JSA if one is not available. Perform a JSA as a part of the investigation to
determine the events and conditions that led to the accident.
As noted earlier, an accident investigation is not complete until a report is prepared and submitted
to proper authorities. Special report forms are available in many cases. Other instances may require
a more extended report. Such reports are often very elaborate and may include a cover page, a title
page, an abstract, a table of contents, a commentary or narrative portion, a discussion of probable
causes, and a section on conclusions and recommendations.
The following outline has been found especially useful in developing the information to be
included in the formal report:
1. Background Information
Where and when the accident occurred
Who and what were involved
Operating personnel and other witnesses
2. Account of the Accident (What happened?)
Sequence of events
Extent of damage
Accident type
Agency or source (of energy or hazardous material)
3. Discussion (Analysis of the Accident – HOW; WHY)
Direct causes (energy sources; hazardous materials)
Indirect causes (unsafe acts and conditions)
Basic causes (management policies; personal or environmental factors)
4. Recommendations (to prevent a recurrence) for immediate and long-range action to remedy:
Basic causes
Indirect causes
Direct causes (such as reduced quantities or protective equipment or structures)
Thousands of accidents occur daily throughout the United States. These result from a failure of
people, equipment, supplies, or surroundings to behave as expected. A successful accident
investigation determines not only what happened, but also finds how and why the accident
occurred. Investigations are an effort to prevent a similar or perhaps more disastrous sequence of
Most accident investigations follow formal procedures. This discussion covered two of the most
common procedures: Change Analysis and Job Safety Analysis. An investigation is not complete
however, until completion of a final report. Responsible officials can then use the resulting
information and recommendations to prevent future accidents.
Note: This checklist covers a majority of industries, therefore, may be too extensive for a small
organization. It is included herein primarily for training purposes. We have included a specific
“Automotive Fleet Shop” checklist after this module/chapter for your use. You may find this
