Summary
School employees include teachers, administrative staff,
facility management personnel and maintenance staff.
These employees perform a wide range of tasks, many
of which can cause bodily injuries or illnesses. You can
prevent such injuries and illnesses by following safe work
practices and using proper protective equipment.
Examples of some injuries and illnesses are:
✎ cuts and amputations from the use of machine
equipment in shops and gardening tools
✎ bruises and abrasions from plants and trees
✎ burns from hot soldering irons, burners, heaters,
and hot engines in auto shop
✎ electrical shock or electrocution from contact with live
electrical parts or electric powerlines
✎ slips and falls in wet and/or cluttered areas
✎ soreness and pain in hands, wrists, shoulders or back
as a result of doing repetitive work, working in an
awkward posture, applying too much force over and
over again, operating vibrating equipment or lifting
heavy loads improperly
✎ itching, swelling, redness of the skin as a result of
exposure to very hot or very cold weather, or contact
with plants and animals
✎ burns and skin disorders as a result of contact with
laboratory chemicals, cleaning solutions, pesticides, or
contact with plants and animals
✎ illness as a result of a contact with people with
infectious diseases or contaminated biological wastes
✎ allergies as a result of dust inhalation, contact with
plants and animals, and insect bits and stings
This Guide provides ways of working safely to prevent
these injuries and illnesses.
Many health and safety behaviours are learned by example.
Children and youth model what they observe. Comprehensive
safe school plans and programs should focus attention on
the strengths and experiences of students, teachers,
administrators and other school personnel.

Section I
Basic Rules of Safety
1. The Law Says...
2. Elements of On-the-Job Safety
3. Safety Tips for New Employees
4. Safety Tips for Supervisors
5. Safety Tips for Teachers
1. The Law Says...
Health and safety laws are meant to protect you.
By law your employer must provide you with a safe and
healthy workplace.
It is your supervisor’s responsibility to make sure that you
understand the safe way of doing your work.
Working safely is your responsibility. You must use
personal protective equipment required by your employer,
follow safety procedures required in your area and report
any hazardous conditions you are aware of.
If you think a task is dangerous for you or your co-workers,
you have the right to refuse to do that job until it can be
done safely. You must report to your supervisor your
intention to refuse dangerous work.
2. Elements of On-the-Job Safety
1. The right way is the safe way of doing your job.
Follow instructions. If you don’t know, ask.
2. Know potential hazards in your work and ways of
working safely to prevent such hazards.
3. Know safety rules for specific jobs and be able to
explain these rules to fellow workers.
4. Follow emergency procedures in case of fires,
medical emergencies, and need of rescue squad.
5. Report all injuries including minor scratches, cuts,
burns, slips and falls. Your employer needs to know,
in order to take corrective action to prevent future
injuries. Follow your school’s procedures for
reporting injuries.
6. Know where emergency equipment is located, such
as fire extinguishers, eyewash stations and safety
showers, and learn how to use this equipment.
2
7. Use personal protective equipment as required by
your employer. Such equipment includes, but is not
limited to, safety glasses, hearing protectors,
respirators, safety boots, hard hats, gloves and face
shields.
8. Learn special safety procedures for particularly
hazardous work such as vessel entry, confined space
entry, electrical work and welding.
9. Follow electrical safety rules when using electrical
equipment, grounding portable electrical tools and
working near overhead power lines.
10. Know how to protect yourself when working
outdoors in very cold or hot weather or in direct
sunshine (UV rays).
11. Perform a circle check before taking out a vehicle.
12. Lock out and tag energy sources (electrical,
mechanical, hydraulic, pneumatic, chemical, etc.)
of all machinery and equipment under maintenance
or repair.
13. Report unsafe practises and unsafe conditions.
14. Wear clothing that’s appropriate to the tasks you
perform. Do not wear loose sleeves, cuffs, rings,
bracelets, nor anything else that may get caught in
moving machinery and cause injury.
Off-the-job safety is equally important.
Safety should not stop when you leave your
school or workplace.

2. Workplace Inspections
Purpose
Occupational health and safety legislation requires regular
workplace inspections. The purpose of an inspection or
safety tour is to identify unsafe conditions, as well as
unsafe practices, and to recommend corrective actions.
Inspection Team
Inspection teams may consist of a mix of personnel such
as employees, supervisors and managers.
Generally, the legislation sets out
procedures for designating a
person or persons to carry out
workplace inspections.
Inspection team members
should always use the
required personal protection
to protect themselves and
to set a good example.
Roles and Responsibilities
The inspections are undertaken in accordance with
a schedule agreed on by the Health and Safety Committee
(JHSC). The inspection teams generally use a checklist as
a guide for conducting inspections.
Inspection Reports
Inspection reports are communicated to all levels of the
organization. Posting inspection reports on the bulletin
board, reviewing them at joint health and safety
committee meetings, and sending sending a copy to
the management for review are all good communication
methods.

4. First Aid
First aid regulations require that employers must provide
first aid facilities, equipment, and trained personnel in all
workplaces. People who hold valid first aid certificates
should make sure that the contents of first aid boxes are
regularly checked and maintained.
For information regarding first aid kits and first aid
training, please contact the local St. John Ambulance
Association or the Canadian Red Cross Society or any
approved organization.
In case of injury or onset of a disease:
1. Promptly obtain first aid.
2. Notify your supervisor/employer.
3. Ask for a treatment memorandum to take to a medical
practitioner or hospital of your choice.
4. Complete and promptly return all forms received
from the Workers’ Compensation Board.
5. Your supervisor should decide on the need for an
accident investigation.
Your employer should post the names and workplace
telephone numbers of the people who have agreed to
provide first aid at the workplace.
Some types of injuries and illnesses may require special

2. Fire Safety
3. Eyewash Stations
4. Emergency Showers
1. Emergencies
Emergencies can be of two types:
Natural emergencies include floods, earthquake,
tornadoes, wind storm, snow storm etc.
Technological emergencies include fire, explosion,
building collapse, radiation, toxic substance
spill, loss of power, water, communication, etc.
The Canadian Standard CSA Z131-M91, published by the
Canadian Standards Association, provides guidelines
for emergency planning. In the US please consult OSHA
publication “Emergency Preparedness and Response” or
OSHA Standard 29CFR1910.38.
2. Fire Safety
Fires
Four Elements—oxygen, fuel, heat, and chain reaction
must be present to cause a fire. Remove any one of these
four elements and the fire will go out.
Oxygen
Take the oxygen away from a
fire by covering it with a wet
blanket, throwing dirt on it or
covering it with chemical or
mechanical foam. These prevent
oxygen from getting to the
source of the fire.
Fuel
Take the fuel away from the
fire. This can be difficult and
dangerous. Pump contents of
flammable liquid storage to an
isolated, empty tank. Close a
valve to stop the flow of liquid
or gas from the tank.

HEAT RE
Heat
Cool a fire source by applying something which absorbs
heat. Water is the most commonly used cooling agent.
Chain Reaction
Interrupt the chain reaction of the fire by using chemical
extinguishing agents such as dry chemical foam or carbon
dioxide.
Classification of FIres
Fires are of four types:
Class A fires involve burning of ordinary materials such
as wood, cloth and paper.
Class B fires involve burning of flammable liquids and
gases such as paint, gasoline and natural gas.
Class C fires involve energized electrical equipment.
The fuel burning could be A, B, or D.
Class D fires involve combustible metals such as
magnesium, titanium, zirconium and sodium.
Fire Extinguishers
SELECT and locate fire extinguishers according to:
✎ the type of potential fire hazard
✎ the degree of hazard
✎ the area to be protected
IDENTIFY locations.
LOCATE extinguishers along aisles that provide access
to an EXIT.
LOCATE extinguishers to minimize travel distance.
LOCATE extinguishers according to fire regulations and
National Fire Protection Association Standards.
KEEP extinguishers fully charged and in their designated
places.
REPLACE used extinguishers with spare extinguishers
during recharging.
19
INSPECT extinguishers at least monthly to ensure that:
✎ they are in their designated places
✎ they have not been tampered with or used
✎ their gauges indicate they are fully charged
✎ they are not corroded or otherwise impaired
✎ they are not damaged

Non-slip Feet
WEAR suitable footwear.
DO NOT USE ladder in a horizontal position as a
scaffold plank or runway.
DO NOT USE makeshift items such as a chair, barrel or
box, as a substitute for a ladder.
DO NOT SPLICE together short ladders to make a
longer ladder. Side rails are not strong enough to
support the extra load.
DO NOT USE ladder in passageways, doorways, driveways
or other locations where a person or vehicle can hit it.
Erect suitable barricades or lock doors shut.
59
DO NOT PLACE ladder against flexible or movable
surfaces.

person is on a singlewidth ladder. Only one
person is allowed on each
side of a double-width
ladder.
MAINTAIN three point
contact by keeping two
hands and one foot, or
two feet and one hand on
ladder at all times.
GRASP rungs when climbing
ladder, not side rails. If
your foot slips on ladder,
it is easier to hold onto
rungs than to side rails.

6. Lock-out Procedures
Purpose
The purpose of lock-out is to protect a person working in
a confined space, a vessel, machine or moving equipment.
Hazards
Accidental starting of machines while someone is working
on them is one of the major causes of amputations and
serious injuries.
Established Procedures
In most instances, your school/board will have an
established lock-out procedure. In the event that the
school does not have an established procedure, use the
following safe work procedures as a guidance to develop
one.
MAKE SURE that you possess an individually numbered
lock and key if you are required to enter a confined
space, vessel, machine or work on moving equipment.
SHUT OFF the machine or equipment, then disengage all
sources of power and lock them in the OFF position.
RELEASE the build-up of air, hydraulic, steam or gas
pressure and ground electric charge build-up before
starting work and valves locked in OFF position.

7. Confined Space Entry
Definition
In Canadian federal legislation, confined space is defined
as follows:
Confined space means an enclosed or partially
enclosed space that
(a) is not designed or intended for human
occupancy except for the purpose of
performing work,
(b) has restricted means of access and egress, and
(c) may become hazardous to any person entering
it owing to:
(i) its design, construction, location or
atmosphere,
(ii) the materials or substances in it, or
(iii) any other conditions relating to it;
Canada Occupational Safety and Health Regulations (SOR/86-304)
Legal definitions of confined space may vary slightly from
one jurisdiction to another.
In Ontario occupational health and safety legislation,
a confined space is defined as follows:
Confined space means a space in which,
because of its construction, location, contents
or work activity therein, the accumulation of a
hazardous gas, vapour, dust or fume, or the
creation of an oxygen-deficient atmosphere may
occur
[Occupational Health and Safety Act and Regulations for Industrial
Establishments R.R.O. 1990, Reg. 851]
Check your OH&S legislation for the definition of
confined space applicable to your workplace.
67
Hazards of Working in a Confined Space
Entry and working in a confined space requires special
care because of the following special features:
1. Design, construction, and location can restrict
movement and exit/getting out.
2. Configuration can trap a person inside.
3. Lack of ventilation can cause oxygen deficiency (less
than 18% oxygen) and build up of hazardous gases
such as hydrogen sulphide and methane.
4. Working inside a confined space may result in the
generation of noise, hazardous gases, vapours, dusts
and fumes, which may accumulate to unsafe levels.
5. Adverse psychological effects due to the feeling of
being in the confined space.
Safe Work Procedures
Your employer is supposed to develop procedures for
working in confined spaces. A confined space entry
program includes the following elements:
✎ Job pre-planning
✎ Equipment inspection
✎ Identification of hazards
✎ Location of hazards
✎ Precautions and procedures for working
✎ Purging or ventilating prior to and during work
✎ Equipment for safe entry and exit
✎ A system to control entry by unauthorized persons
✎ Training on precautions and procedures for entry
and work
✎ Arrangements for rescue
✎ Communication – keeping in touch with outside
workers
✎ Secure closing of confined space entry after the work
is done.
68
8. Toxic Chemicals
MAKE SURE that you receive training in the safe use,
handling, disposal and clean-up of hazardous
chemicals and products.
ENSURE that all containers are properly labelled.
READ the label and be familiar with the potential hazards
of the products you use.
MAKE SURE that you know where to find Material
Safety Data Sheets (MSDS) for the products you use.

10. Basic Electrical Safety
INSPECT tools, power cords, and electrical fittings for
damage prior to each use. Repair or replace damaged
equipment.
SWITCH OFF tools before connecting them to a power
supply.
DISCONNECT power supply before making adjustments.
ENSURE that electric tools are properly grounded or
double-insulated. The grounded tool must have an
approved 3-wire cord with a 3-prong plug. This plug
should be plugged in a properly grounded 3-pole
outlet.TEST all tools for effective grounding with a
continuity tester or a ground fault circuit interrupter
(GFCI) before use.
KEEP power cords clear of tools during use.
SUSPEND power cords over aisles or work areas to
eliminate stumbling or tripping hazards.
REPLACE open front plugs with dead front plugs. Dead
front plugs are sealed and present less danger of shock
or short circuit.
Open Front Plug
CHECK power cords and plugs daily. Discard if worn or
damaged. Have any cord that feels more than
comfortably warm checked by an electrician.
ELIMINATE octopus connections.
PULL THE PLUG, NOT THE CORD.
71
USE extension cords only to temporarily supply power
to an area that does not have a power outlet.
ENSURE that the extension cord is adequate for the
length of cord and the power (wattage) requirements
of power tools, etc.
KEEP power cords away from heat, water and oil. They
can damage the insulation and cause a shock.
DO NOT WEAR gloves, loose clothing or jewellery
while using rotating power tools.
DO NOT BYPASS the switch and operate the tools by
connecting and disconnecting the power cord.
DO NOT USE electric tools in wet conditions or damp
locations unless the tool is connected to a GFCI.
DO NOT CLEAN tools with flammable or toxic solvents.
DO NOT OPERATE tools in an area containing explosive
vapours or gases.
DO NOT USE light duty power cords.
DO NOT CARRY electrical tools by the power cord.
DO NOT TIE power cords in knots. Knots can cause
short circuits and shocks. Loop the cords or use a
twist lock plug.
DO NOT PLUG several power cords into one outlet.
DO NOT DISCONNECT power supply by pulling or
jerking cord from the outlet. Pulling the cord causes
wear and may cause a shock.
DO NOT USE extension cords as permanent wiring.
DO NOT ALLOW carts and trolleys to pass over
unprotected power cords. Cords should be put in
conduit or protected by placing planks alongside
them.
72

PROTECT cutting edges.
Refuelling Equipment
SHUT OFF engine and allow it to cool.
FILL the fuel tank before starting a job.
POSITION yourself comfortably so that you can refuel
without slipping.
REMOVE the fuel cap slowly, holding it at the semilocked position until pressure is released.
ALLOW the nozzle to empty by keeping it in the filler
opening for a few moments after shutting off fuel
flow.
REPLACE the fuel cap after checking to see that its
venting is not clogged.
STORE fuel in sturdy, approved containers identified
according to WHMIS requirements.
HAVE fire extinguishers and other firefighting equipment
nearby.
74
DO NOT SMOKE or have an open flame while
refuelling. Gas fumes are heavier than air and will
drift downward from the container. The vapour, not
the liquid, burns.
DO NOT SPILL any fuel on equipment. If you do, wipe
up and allow any residue to dry before starting the
engine.
DO NOT RUN if your clothing catches fire. STOP,
DROP and ROLL. Quickly remove the blazing
garment, or drop to the ground and roll slowly,
or wrap yourself in a blanket.

10. Electromagnetic Radiation
1. Indoor Air Quality (IAQ)
Indoor Air Quality (IAQ) refers to the total indoor
environment including:
✎ air contaminants entering the building with outdoor
air intake by the ventilation system,
✎ airborne biological agents such as mould, fungi, and
substances from plants,
✎ emissions from furniture, carpets, carpet glues, paints
and varnishes,
✎ tobacco smoke, carbon dioxide in the exhaled air,
body odours, perfumes from building occupants,
✎ toxic gases, vapours, fumes, etc. from laboratories,
photocopiers and other processes and activities taking
place inside the building, and
✎ indoor environment factors such as temperature,
humidity, noise, lighting and air movement.
Recognition and Control of Indoor Air
Problems
The best method of determining whether or not there is
an indoor air problem is to ask people. A wide variety of
questionnaires are available to perform occupant response
survey.
Monitoring of indoor air contaminants is needed to plan
remedial action. As a starting point, one must make sure
that the ventilation is adequate. This is done by
measuring carbon dioxide (CO2) level in the air.
Ventilation rates required to maintain low level of CO2
help improve the overall indoor air quality by dilution of
indoor contaminants. Indoor CO2 concentrations below
1000 ppm (parts per million) are generally accepted as a
good indicator of ventilation effectiveness. The
concentration of CO2in outdoor air is about 350 ppm.
86
Standard
The ASHRAE 62-1989 standard of the American
Society of Heating, Refrigerating and Air-Conditioning
Engineers is the most widely used standard for
ventilation and indoor air quality.
Symptoms of Poor Indoor Air Quality
Health and comfort effects believed to arise from poor
indoor air quality are collectively known as Sick Building
Syndrome (SBS). The symptoms of SBS include
headache, fatigue, dry throat, shortness of breath, skin
irritation, dizziness, itchy eyes, bleeding nose and general
malaise or non-specific illness.
SYMPTOMS OF POOR IAQ
Headache/Dizziness,
Excessive Fatigue
Sinus Congestion/
Headache
Itchy/Watery Eyes
Dry/Sore Throat,
and/or Cough
Shortness
of Breath
Nausea/
Stomach Upset
Skin Irritation
87
2. Noise
People who operate noisy equipment such as tractor lawn
mowers, circular saws, wood planers and vacuum cleaners
are likely to be exposed to harmful levels of noise.
Noise is too loud when:
✎ You have difficulty talking to someone at arm’s length
✎ You feel ringing sound in your ears after prolonged
exposure
✎ Your hearing is numbed at the end of the work shift
and comes back the next morning
Noise exposure for several years can cause permanent
hearing loss which cannot be cured by medical treatment.
Everyone is not equally affected. However, as the level of
noise and exposure time increases more and more people
are affected.
The loudness of noise is expressed as sound level in
dB(A), A-weighted decibel units.
COMMON SOUND LEVELS dB(A)
Wood hogger chipper
Power mower, snowmobile
Chain saw
Lawn mower
Sidewalk snowplow
Salt and sand truck
100 - 110 dB(A)

90 - 100
Exposure limit
85 - 90
Vacuum cleaner
Normal conversation
Whisper
80 - 85
60 - 65
30 - 40
Noise regulations set exposure limits at 85-90 dB(A) for
an eight hour exposure, five days a week. The purpose of
these limits is to prevent/minimize chances of hearing loss.
Check with your local occupational health and safety
agency for the exposure limits that apply to you.
The best method of protection against noise is to use
quieter machines. As an interim measure you should use
hearing protection as required by your employer.
88
3. Ventilation
The purpose of ventilation is to control the temperature,
humidity, odour, and airborne contaminants and to
introduce fresh air.
Types of Ventilation
1. Dilution ventilation dilutes contaminant volume by
bringing in outside air and exhausting used
(contaminated) air.
2. Local ventilation exhausts the toxic gases, fumes,
dust and vapours before mixing occurs. Fume hoods
are the most commonly used type of local exhaust
ventilation.
Dilution ventilation is used when:
✎
✎
✎
✎
contaminant is relatively non-toxic
there are large number of sources or mobile sources
emission sources are widely distributed in an area
diluted air is not contaminated
Local ventilation is used when:
✎ contaminant is moderately or highly toxic
✎ single or small number of fixed sources are present
✎ direct worker exposure is possible
Standard
Ventilation standards are defined in building codes. The
ASHRAE (American Society of Heating, Refrigerating
and Air Conditioning Engineers) Standard 62-1989 is
referenced in most building codes.
89
4. Lighting
IDENTIFY sources of glare. Place a mirror on the desk
and look for images. Bare light bulbs or bright lights
reflected in the mirror cause glare.
POSITION desk with window to the side of the worker.
POSITION desk so that ceiling lights are to the sides.
Avoid placing desk where light fixtures are directly in
front.
USE indirect lighting to avoid shadows.
CHECK fluorescent lights for flicker. Replace fluorescent
tubes regularly and maintain fixtures properly.
LOOK up and away from work frequently to rest the
eyes.
WORK from good, clear copy. Higher light levels are
required for poor copy.
ENSURE that storerooms, corridors and stairways are
well lit.
90
ADJUST window blinds or drapes to control light levels
and glare.
USE non-glare finishes and neutral colours on
walls and furniture. The colour and
finish of a surface determines
how much light it reflects.
USE adjustable task lights to
increase light levels when
needed.
DO NOT HANG glossy pictures or
objects where light will reflect into eyes.
Appropriate light levels depend on visual preferences and
type of work. In the following chart, the higher ranges are
for workers with poorer vision and for work requiring
high speed or accuracy
APPROPRIATE LIGHT LEVELS

91
5. Working in Hot Environments
Working in hot environments can be uncomfortable and
also, may adversely affect our health. How hot we feel
depends on temperature, humidity (moisture content of
the air), wind speed (air movement), and the type of
work.
Humidex
In the weather forecast, the degree of environmental heat
is often given in terms of humidex which is determined
by taking into account the temperature and humidity of
the ambient air.

Potential Health Problems
Heat Stroke
The most serious heat illness is heat stroke. Signs of heat
stroke include dry, hot skin due to failure of sweating and
complete or partial loss of consciousness.
Heat stroke can be fatal and requires prompt
first aid and medical attention.
92
Other Health Disorders
Less severe health problems include:
✎ Heat edema—swelling of the ankles.
✎ Heat rashes—tiny red spots on the skin that cause a
prickling sensation during heat exposure.
✎ Heat cramps—sharp pains in muscles resulting from
the failure to replace salt lost from sweat.
✎ Heat exhaustion—weakness, dizziness, visual
disturbances, intense thirst, nausea, headache,
vomiting, diarrhoea, muscle cramps, breathlessness,
palpitations, and tingling and numbness of the hands
and feet.
✎ Heat syncope (fainting)—caused by the loss of body
fluids through sweating and by lowered blood
pressure, due to pooling of blood in the legs while
working in a standing position.
If you notice any of the above symptoms go to a cool place.
Preventing Heat Related Illnesses
✎ Acclimatization—People who work regularly in hot
environments develop a certain degree of tolerance
(acclimatization) for heat. Most of the acclimatization
occurs in the first three or four days, and complete
acclimatization may require seven to eleven days.
✎ Clothing—Loose cotton clothing provides adequate
protection in hot and humid conditions.
✎ Work/Rest Schedule—A schedule of work-rest
periods is generally recommended for working in hot
conditions. Ask your supervisor about your board's
policy in this regard.
✎ Drinking Water—You should drink plenty of cool
10°–15°C (50°–60°F) water every 15 to 20 minutes
even though you may not feel thirsty. Thirst is an
inadequate indicator of the body’s need for water.
93
6. Working in Cold Environments
Working in cold weather can be dangerous to the
unprepared, and to people without adequate protective
clothing. Two types of cold hazards are common:
hypothermia and frostbite.
Hypothermia can be fatal. It results from the cooling of
the deep inner body or “core” to a temperature below
34.5°C (94.1°F) due to prolonged exposure to cold.
Persons exhausted during physical work are more prone
to hypothermia. The victim can become listless, confused
and make little or no effort to keep warm.
The hypothermia victim should be immediately warmed,
either by being moved to a warm room or by the use of
blankets. In severe cases of hypothermia, immediate
medical care is necessary.
Caution
Consumption of alcohol does not increase
tolerance for cold. Instead, it increases the risk
of hypothermia.
Frostbite is freezing of the body tissues as a result of
extremely cold temperatures or contact with extremely
cold metallic objects such as an automobile or a fence.
Effect of Wind
At any temperature, one feels colder when it is windy.
The combined effect of cold and wind speed is expressed
as "wind chill" or “equivalent chill temperature” (ECT).
For exposed skin, continuous exposure should not be
allowed when ECT is -32°C (-25°F) or lower.
94
Protective Clothing
Multiple layers of light weight loose fitting clothing provide
better protection against the cold compared to single thick
layer clothing. Eye protection must be separated from
respiratory channels (nose and mouth) to prevent exhaled
moisture from fogging and frosting eye shields. For work
in wet conditions, the outer layer of clothing should be
waterproof. Clothing should be kept clean. Dirt destroys
its insulating ability. Clothing must be dry.
Gloves should be used below 4°C (39°F) for light work
and below -7°C (19°F) for moderate work. For work
below -17.5°C (0°F), mittens should be used. Felt-lined,
rubber bottomed, leather-topped boots with removable felt
insoles are best suited for heavy work in cold.
More than 50 percent of body heat can be lost through the
head when the rest of the body is covered. A wool knit
cap or a liner under a hard hat reduces excessive heat loss.
95
7. Portable Classrooms
Health Concerns
There are reports that students and teachers in portable
class rooms experience symptoms such as:
✎ irritation of nose, throat and skin;
✎ nose bleeding, muscle aches, extreme fatigue;
✎ breathing problems from allergic reactions such as
asthma
✎ cold- or flu-like symptoms: runny nose, phlegm in the
throat, coughing, wheezing;
✎ hoarseness and sore throats;
✎ itchy and inflamed eyes;
✎ nausea, joint pain, and headaches.
People who have allergies are more likely to be affected
compared to others.
Cause of Sickness
The possible cause of such sickness is believed to be poor
indoor air quality and indoor air pollution. Similar illness
can occur in any classroom with inadequate ventilation.
Lack of adequate ventilation results in build-up of moisture,
dusts, organic vapours, and emissions from the human
body in the indoor air. High moisture content of the air
(relative humidity) results in moulds and mildew growth.
Moulds release spores into the building air. Inhalation of
spore contaminated air increases the risk of allergies and
other illnesses. All exposed persons are not equally affected.
However, as level of air contamination and/or exposure
time increases more and more people are affected.
The (Ontario) Inter-ministerial Committee on Indoor Air
Quality (1987) and the ASHRAE 62-1989 standard on
indoor ventilation recommend that an outdoor air supply
of 15 cubic feet per minute (cfm) per occupant is necessary
to provide a healthy indoor environment. This ventilation
rate assumes that the outside air is evenly distributed in
the room.
96
High density of children in the classroom, water leakage
and wet clothing are the main sources of moisture in a
portable classroom. Moisture condenses on walls, windows,
ceiling and other surfaces and serves as a site for mould
growth. Mould growth may not be visible when condensation
of the moisture occurs inside the wall. Absence of water
staining on walls does not necessarily rule out the presence
of mould.
How To Know if A Portable Classroom
Has IAQ Problems
Widespread complaints of colds, allergies, fatigue, or flulike symptoms by teachers and students indicate potential
indoor air problems. The following are typical patterns of
the onset of these health problems:
✎ the symptoms are widespread within a class or school,
✎ the symptoms improve when the students or staff
leave the school building for the day, and
✎ persons with allergies, asthma, or chemical sensitivities
are affected indoors but symptoms disappear outdoors
Control Measures
Mould Removal
REMOVE water-damaged wallpaper, carpeting, foamrubber carpet pads, drapery, upholstery fabric and air
filters.
CLEAN baseboards, hardwood floors, ceiling tiles,
cement, wood beams, framing and roofing material.
VACUUM the entire area and immediately discard the
disposable bags.
STEAM clean all carpets and dry quickly.
MINIMIZE dispersal of any mould into the air.
WEAR correctly fitted mask with a HEPA (high efficiency
particulate air) filter to avoid breathing any airborne
mould spores while removing moulds.
DISPOSE of the material in sealed plastic bags, and if
you know that the mould is one of the toxic varieties,
treat the bags like hazardous waste.
97
DECONTAMINATE the mouldy areas. A 10-percent
solution of household bleach can be an effective
disinfectant. However, it should be used only by those
trained to use it safely using appropriate chemicalresistant gloves, respirator and chemical splash
goggles.
SCHEDULE cleaning when the building is unoccupied to
minimize the exposure of other people to airborne
mould spores.
Mould Growth Prevention
ENSURE there are no leaks from roofs and broken water
pipes.
BLOCK OFF areas where moisture can seep through
cement foundations and can dampen the floor,
carpeting and walls. This will minimize condensation
and indoor dampness.
ENSURE that the heating, ventilation and air conditioning
system provides adequate outside air, air filtration and
exhaust of air contaminants. A minimum of 15 cubic
feet per minute (cfm) of fresh air per occupant should
be flowing through the room at all times.
ENSURE that filters are changed or washed, and that the
water reservoirs are treated or changed regularly.
USE dehumidifiers to reduce humidity to 30- 50 percent.
If humidifiers are needed in winter months to
overcome dry indoor air, make sure they do not use
re-circulated water.
CLOSE windows tightly during winter months. Poor
ventilation and poor air circulation can cause
accumulation of humidity and growth of microorganisms, including mould on window frames.
Renovations
When the renovations are being done:
REPLACE the affected material,
ENSURE adequate ventilation, and
INSTALL proper air – vapour barriers.
98
8. Asbestos Management
Asbestos is a well known carcinogen. Exposure to
asbestos has been linked to mesothelioma (a rare type of
cancer of the pleura-covering of the lungs and the inner
surface of the chest wall), asbestosis (scarring of the
lungs), and other cancers which may appears 10–20
years or more after exposure. Identification and removal
of asbestos containing materials is the best method of
eliminating the risk of harmful exposures.
In the past, common uses of asbestos included:
✎ insulation, fire proofing, sound proofing, ceiling and
floor tiles, acoustic spackles, and vinyl asbestos floor
tiles;
✎ thermal insulation on pipes, boilers, and ceilings, fire
protection on structural steel beams;
✎ lining of heating and ventilation duct work, window
glazing, and adhesives.
Now asbestos is not used in these products but some of
the older, installed products may still contain asbestos.
When contained in stable solid building materials,
asbestos is not released into the air and hence, does not
pose health risk. Renovation work or damage to building
materials can produce dry, crumbly (friable) material
capable of releasing asbestos fibres in the air. Airborne
asbestos fibres enter the lungs with the inhaled air.
Specific procedures and precautions have been developed
to prevent the release of asbestos fibres in the air.
Extreme caution is necessary to protect children from
asbestos exposure.
The US government has adopted the Asbestos Hazard
Emergency Response Act (AHERA–40 CFR 763) in
1987. In Canada, guidelines are available from school
boards and the government health and safety departments.
In consultation with the health and safety committee,
each school should establish their own asbestos
management plan. The following is a general outline of
the actions recommended to control asbestos exposure:
99
ARRANGE inspection by a qualified person to identify
asbestos containing materials in the school.
IDENTIFY type and location of all asbestos containing
materials present in the school.
MAINTAIN an inventory of all asbestos containing
materials by location. This inventory should be used
by the school maintenance staff repair workers
performing work on or near asbestos-containing
materials.
ESTABLISH an asbestos management plan and strategy.
POST warning signs in all routine maintenance areas to
inform maintenance personnel that asbestos is present
in the school.
ASSIGN responsibility to supervise the implementation
of the asbestos management plan.
TRAIN the custodial staff in asbestos awareness and safe
work practices.
ESTABLISH a procedure for reporting damaged or
exposed materials that may cause asbestos exposure.
ESTABLISH procedures for proper removal and disposal
of asbestos containing materials and ensure that all
employees understand and follow these procedures.
NOTIFY utility workers and other personnel working in
areas where asbestos containing material is present.

9. Ultraviolet Rays
In summer months, outdoor work may cause damage to
the skin and eyes due to ultraviolet (UV rays) radiation
exposure. UV rays are an invisible part of sunlight.
Besides direct exposure to sunlight, harmful UV ray
exposures are possible due to reflections from water, sand
and concrete.
Effect on the Skin
UV rays cause darkening of the skin, skin burns and
erythema (reddening of the skin). Prolonged exposure
increases the risk of skin cancer.
Certain substances increase the risk of damage due to
UV radiation. These are known as photosensitizing
agents. Such agents include certain medications,
tranquilizers, cosmetics, plants, weeds and coal-tar
creosote. If you are using medication consult your doctor
regarding the possibility of photosensitizing action. In any
case, take steps to decrease exposure to UV rays.
Effect on the Eyes
The eyes are particularly sensitive to UV radiation. A
short exposure can cause pain and temporary effects such
as watering and blurred vision.
UV Index
The Environment Canada weather forecast service rates
the UV intensity as UV index on a scale of 0 to 10. The
implications of the UV index are summarized in the
following table.

✎ Avoid midday sun (10:00 am–3:00 pm).
✎ Wear clothing that is tightly woven to block
sunlight.
✎ Wear a broad-brimmed hat that will shade your face,
neck and ears.
✎ Apply waterproof sunscreen with a sun protection
factor (SPF) of 15 or higher to all exposed skin.
✎ Wear UV filtering sunglasses.
102
10. Electromagnetic Radiation
Computer monitors, commonly known as video display
terminals (VDT) emit electromagnetic radiation in two
frequency ranges—extremely low frequency (ELF) and
very low frequency (VLF). The source of ELF radiation is
the electrical power supply to the VDT. The frequency of
ELF radiation is the same as the frequency of electric
power which is 60 cycles per second or 60 Hz in North
America and 50 Hz in Europe. The source of VLF
radiation is the electronic components that produce
pictures and letters on the VDT screen. The VLF radiation
from a VDT is in the 15-30 thousand Hz range.
There have been numerous studies to investigate a possible
link between VDT use and adverse health effects, mainly
on effects on pregnancy. Results obtained to date have not
provided conclusive evidence of association between VDT
use and adverse health effects.
The American Conference of Governmental Industrial
Hygienists (ACGIH), Health Canada and several other
expert organizations have recommended exposure limits
for electromagnetic radiation. These exposure limits are
intended to prevent immediate health effects due to currents
induced in the body by the external electromagnetic
radiation. The levels of electromagnetic radiation form a
VDT are far lower than these recommended exposure
limits.
There are no exposure limits applicable to long-term
effects such as adverse pregnancy outcome because there
are no dose-response data for such effects. In view of the
scientific uncertainty, prudent avoidance is often advised.
This is achieved by reducing exposure time and keeping a
good distance from the monitor. Both ELF and VLF
radiation levels rapidly decrease as distance from the
monitor increases. At about one arm length distance from
a VDT, the electromagnetic field is extremely low.

5. Workstation Exercises
1. Repetitive Motion Injuries (RMIs)
Repetitive motion injuries (RMI) are injuries of the
muscles and joints in the body. These are also known as
musculoskeletal injuries (MSI), culmulative trauma
disorder (CTD) and work-related musculoskeletal
disorder (WMSD).
Contributing factors to RMI problems are:
✎ static body positions which cause muscle tension, require
energy, and reduce the flow of blood to the muscles.
✎ repetitive motions which cause tiredness, pain and
possible overuse injuries.
✎ uncorrected vision, glare or shadows which force
workers to use awkward body positions to see work
properly.
✎ workstations which are too high or low and have
needed objects placed too far away from workers.
✎ improperly adjusted chairs which place pressure on
the underside of the legs, back of knees and impair
blood circulation.
✎ hard floors which cause feet and legs to ache if
workers walk or stand for long periods.
Preventing Repetitive Motion Problems
The key to preventing RMI is to avoid long periods
working in one position and repeating the same motions.
ENSURE that chairs and work surfaces are adjusted
properly and there is enough space to work in a
comfortable position.
ELIMINATE glare by properly positioning lights and desks.
ELIMINATE shadows by using task lamps.
ADJUST window curtains and blinds as conditions vary
through the day.
VARY tasks to change body position and mental
activities. Good work/rest schedules help.
PLACE frequently used items within easy reach. Store
infrequently used items farther away.

DO NOT SLOUCH.
DO NOT SIT for more than 50 minutes at a time.
What to Avoid While Sitting
Poor arrangement of the workstation fosters an awkward/
poor body position. Poor body position hinders breathing
and blood circulation and contributes to injuries affecting
people's ability to move.
111
AVOID sitting on a chair that is too high.
AVOID bending the head forward. This prevents neck
injury.
AVOID sitting without lumbar support. This prevents
back pain.
AVOID working with arms raised. This prevents neck and
shoulder pain.
AVOID bending wrists. This prevents muscle cramps.
AVOID working with unsupported forearms. This
prevents shoulder pain.
AVOID cramming thighs under worktable. This reduces
blood circulation.
AVOID working with legs dangling. This destabilizes the
body and causes tiredness.
AVOID pressure on underside of thighs. This reduces
back flow of blood and can cause swelling legs.
AVOID sitting on a chair that is too low.
✎ It disrupts blood circulation in lower legs, causing
swelling.
✎ It puts pressure on internal organs.
✎ It creates too much pressure on buttocks and
causes discomfort.
DO NOT WORK with a worktable that is too high.
✎ It prevents use of proper lumbar support and can
cause back injury.
✎ It overstretches spine and can cause back injury.
✎ It forces the head to bend forward and can cause
neck injury.
✎ It stresses shoulders and causes pain.
✎ It tires the whole body.
DO NOT SIT on a chair that has poor support. It can
overturn, injuring you.

if using a fixed height work surface.
6
ADJUST the chair height so elbows are about the same height
as the work surface.
7
USE a foot rest if feet cannot rest flat on the floor or if there is
pressure on the back of the legs. The foot rest should be
adjustable and support the whole foot.
Work Surface
MAKE adjustments so work surface is the correct
working height.
ENSURE that the work surface is large enough to hold
materials.
STORE frequently used items in the most convenient
place.
AVOID cramping legs under work surface.
AVOID over-reaching and twisting.

2. Safety Glasses
Selection of Safety Glasses
Lenses CSA Z94.3/ANSI Z87.1-certified safety glasses
have glass, plastic or polycarbonate lenses. They are
stronger than regular lenses, are impact-resistant, and
come in prescription and non-prescription (plano)
forms.
Lense Markings The manufacturer’s logo is marked
(or etched) on all approved safety lenses.
Frames Safety frames are stronger than street-wear
frames and often heat resistant. They are designed to
prevent lenses from being pushed into the eyes.
Frame Imprint All CSA-certified safety frames have the
imprint “Z94.3” stamped on them and may have CSA
logo imprinted on the temple.

Lens Marking
Correct Fit of Safety Glasses
ENSURE your safety glasses fit properly. Eye size,
bridge size and temple length all vary, so safety
glasses need to be individually assigned and fitted.
WEAR safety glasses so that the temples fit comfortably
over the ears. The frame should be as close to the face
as possible and adequately supported by the bridge of
the nose.
Proper Care of Safety Glasses
Safety glasses need maintenance.
CLEAN your safety glasses daily with recommended
lens cleaning material. Follow the manufacturer’s
instructions. Avoid rough handling which can scratch
lenses. Scratches impair vision and can weaken glass
lenses.
STORE your safety glasses in a clean, dry place where
they cannot fall or be stepped on. Keep them in a case
when they are not being worn.
REPLACE scratched, pitted, broken, bent or ill-fitting
glasses. Damaged glasses interfere with vision and do
not provide adequate protection.
123
3. Safety Footwear
Safety footwear is designed to protect
feet against a wide variety of injuries.
Impact, compression and puncture are the most common
types of foot injury.
CHOOSE footwear according to the hazard. Refer to
CSA Standard Z195 “Protective Footwear” or ANSI
Z41 in the US.
SELECT CSA-certified footwear. Ensure that it has the
proper rating for the hazard and the proper sole for
the working conditions.
WALK in new footwear to ensure it is comfortable.
LACE up boots fully. High-cut boots provide support
against ankle injury.
USE a protective coating to make footwear waterresistant.
USE metatarsal protection (top of the foot between the
toes and ankle) where there is a potential for injury.
INSPECT footwear regularly for damage.
REPAIR or replace worn or defective footwear.

4. Safety Headwear
Headwear consists of a shell and the
suspension. These work together as a
system and both need regular inspection and maintenance.
CHOOSE the correct headwear for the job. Refer to ANSI
Standard Z89.1 (1997) or CSA Standard Z94.1,
Industrial Protective Headwear.
Protective headwear are of the following two types:
Type I
Hat (full brim)
Type II
Cap (with or without peak)
Protective headwear ( safety hats and caps) are
classified as follows:
Type A
General Use, Limited Voltage Protection
Type B
High Voltage Protection
Type C
General Use, Metallic No Voltage Protection
Type D
Impact and Penetration Protection
INSPECT headwear before each use
CLEAN the suspension and shell regularly.
DO NOT TRANSPORT headwear in rear windows of
vehicles.
Shell
The shell is rigid and light, and is shaped to deflect falling
objects. Correct maintenance is important.
INSPECT and replace a shell that shows signs of wear,
scratches or gouges. A shell exposed to heat,
sunlight and chemicals can become stiff or brittle.
REPLACE headwear when hairline cracks start to appear.
These cracks will spread and widen.
REPLACE headwear that has been struck, even if no
damage is visible.
REMOVE and destroy any headwear if its protective
abilities are in doubt.
126
DO NOT DRILL holes, alter or modify the shell.
Alterations may reduce the protection provided by the
headwear.
DO NOT PAINT the plastic shell. Paint solvents can
make plastic headwear brittle and more susceptible to
cracks. Instead, use reflective marking tape to make
number or symbols for identification purposes. Metal
headwear may be painted.
DO NOT USE winter liners that contain metal or
electrically conductive material.
DO NOT USE metal labels on Class B headwear.
DO NOT DRAW chin strap over brim or peak of Class B
headwear.
Suspension
The suspension system holds the shell away from the
head and acts as a shock absorber. It also holds the shell
in place on the head and allows air to flow freely.
ADJUST headband size so that headwear will stay on
when wearer is bending over, but not so tight that it
leaves a mark on the forehead.
ENSURE that the suspension is in good condition. The
main purpose of the suspension is to absorb energy.
LOOK closely for cracked or torn adjustment slots,
frayed material or other signs of wear.
CHECK suspension lugs carefully. Perspiration and hair
oils can cause wear. Long periods of normal use can
damage the suspension.
REPLACE suspension that has torn or broken treads.
DO NOT PUT anything inside headwear. There must be
a clearance inside the headwear while it is being
worn. In the event of a blow to the head, that space
helps absorb the shock.
127
5. Hearing Protection
Hearing protectors reduce the amount
of sound energy reaching the ears and
hence, reduce the risk of hearing loss.
SELECT hearing protection that is correct for the job.
Refer to CSA Standard Z94.2 Hearing Protectors or
ANSI Standard S12.6.
Earplugs are inserted to block the ear canal. They
may be premoulded (preformed) or mouldable.
Canal Caps are comprised of two ear plugs held over
the ends of the ear canal by a rigid headband.
Ear muffs are comprised of hard outer cups, soundattenuating material and soft ear cushions which
fit around the ear and hard outer cups. They are
held together by a head band.
DO NOT USE radio headsets as a substitute for hearing
protection.
DO NOT MODIFY hearing protectors.
Proper Care of Hearing Protection
REFER to manufacturer’s instructions.
CHECK hearing protection regularly for wear and tear.
REPLACE ear cushions or plugs that are no longer
pliable.
REPLACE unit when head bands are so stretched that
they do not keep ear cushions snugly against the head.
DISASSEMBLE ear muffs to clean.
WASH hearing protectors with a mild liquid detergent in
warm water, and then rinse in clear warm water.
ENSURE that sound-attenuating material inside cushions
does not get wet.
128
Proper Fit of Hearing Protection
FOLLOW manufacturer’s instruction.
ENSURE hearing protector is tightly sealed within the
ear canal or against the side of the head.

129
6. Hand Protection
Hands are the most vulnerable to
injury from accidental contact with
tools, machines, chemicals, and hot and cold objects. In
some circumstances gloves may provide adequate hand
protection. Barrier creams are used in situations where
use of gloves is not practicable for protection against
chemical exposure.
Gloves
Selection of gloves depends on the type of exposure.
Different types of gloves are available to provide
protection against different types of exposure. Consider
all potential exposures when selecting gloves. Check
MSDS of chemicals to determine suitable gloves. Consult
local safety supplier to select from available types of
gloves.
Protective Creams
Barrier creams may be used for protection against chemicals,
solvents, fumes, dusts and micro-organisms in cases
where all other methods of protection are impractical.
The application of barrier cream before starting the work
provides a protective layer which limits the contact
between the hand and the hazardous substances.
The advice of a specialist should be sought in the selection
and correct use of a barrier cream which will provide best
protection.
130
7. Respirators
A respiratory could save your life or
prevent serious illness or disease.
However, in schools dust masks will probably be the most
commonly used respiratory protective device (eg. in wood
working shop).
General
FOLLOW the respirator protection program developed
by your employer/supervisor, including training and
fit testing.
USE the type of respirator as prescribed by your
employer/supervisor.
INSPECT before and after each use and during cleaning.
INSPECT equipment designated for “emergency use” at
least monthly, in addition to after each use.
REPLACE all parts that are cracked, torn, broken,
missing or worn.
FOLLOW manufacturer’s instruction and CSA Standard
Z94.4 or ANSI Z88.2 for care and maintenance.
The following sections apply to respirators other than
dust masks.
Facepiece
ENSURE that there are no holes or tears.
INSPECT for cracked, scratched or loose-fitting lenses.
For full facepiece, check for missing mounting clips.
ENSURE that metal nose clip forms easily over the
bridge of the nose on disposable respirators.
Headstrap/Harness
CHECK webbing for breaks.
LOOK for deterioration of elasticity.
TEST excessively worn head harness.
131
Inhalation and Exhalation Valves
ENSURE valve and valve seat are free of detergent
residue, dust particles, or dirt which may cause a poor
seal or reduce efficiency.
REPLACE missing or defective valve cover.
Filter Element
ENSURE that filter and mask are certified for use together.
CHECK filters to see that they are approved for the hazard.
INSPECT both filter threads and facepiece threads for wear.
CHECK filter heads for cracks or dents.
CHECK end of service life indicator on gas masks.
Check expiration date.
Repair, Cleaning and Storage
FOLLOW manufacturer’s instructions.
WASH with a mild dish detergent or a combination of
detergent and disinfectant. Use a brush and warm
water (49–60° C).
RINSE with clean water, or rinse once with a disinfectant
and once with clean water. The clean water rinse
removes excess detergent or disinfectant that can
cause skin irritation or dermatitis.
DRY on a rack, clean surface or hang from a clothes line.
Position the respirator so that the facepiece rubber
will not “set” crookedly as it dries.
STORE respirator at the end of each shift to protect it
from dust, sunlight, heat, extreme cold, excessive
moisture, and chemicals.
CLEAN and disinfect shared respirators after each use.
PERMIT only trained and qualified personnel to repair
respirators.
RECORD repairs and/or inspections.
CHECK for distortion caused by improper storage.
DO NOT CLEAN with solvents.
DO NOT MIX parts from different manufacturers.

Each of the provinces and the federal government have
their own OH&S legislation. The details of the OH&S
legislation vary slightly from one jurisdiction to another
but the basic elements are the same.
Most Canadian jurisdictions have a general duty provision
in their OH&S legislation which requires employers to
take all reasonable precautions to protect the health and
safety of employees.
New legislation, commonly known as Bill C-45, was
proclaimed into force on March 31, 2004. If this OH&S
duty is disregarded and bodily harm or death results, an
organization could be charged with criminal negligence.

3. Workplace Hazardous Materials
Information System (WHMIS)
WHMIS (Pronounced whimiss)
WHMIS applies to all Canadian workplaces. It requires
that all workers who work with or near a hazardous
substance (controlled product) be informed about its
potential hazards and recommended safe work practices.
WHMIS requires that information be provided in three ways:
l. All controlled products used in the workplace must
have a WHMIS label on the container.
2. Material Safety Data Sheets (MSDS) and hazard
information must be readily available in the
workplace. A MSDS summarizes the health and
safety information about the product.
3. Workers must receive training to be able to recognize
and work safely with chemicals.

145
9. US OH&S Legislation
General Outline
In the United States (US) the Occupational Safety and
Health Act is popularly known as OSHAct. The
Occupational Health and Safety Administration (OSHA)
is responsible for administering the OSHAct.
The OSHAct does not cover the following four categories
of people:
✎ self-employed persons
✎ farms which employ only immediate family members
of the farm employer
✎ employees covered by other legislation
✎ state and local government employees
OSHA regulations are published in Title 29 of the Code
of Federal Regulations as:
✎ 29 CFR Part 1910— Occupational Safety and
Health Standards
✎ 29 CFR Part 1926—Construction Standards
These standards define exposure limits, exposure
monitoring methods, medical surveillance and protective
measures.
Duties of Employers
The OSHAct sets out two main duties for employers:
✎ Employers must provide a workplace which is free
from hazards that are known to cause or likely to
cause death or serious physical harm to employees.
✎ Employers must comply with occupational safety
and health standards under the Act.
146
Duties of Employees
Employees must comply with occupational safety and
health standards, rules, regulations and orders which are
applicable to their own conduct and actions.
Key Provisions
Some of the key provisions of the OSHAct are to:
✎ assure, insofar as possible, that every employee has
safe and healthy working conditions
✎ require employers to maintain accurate records of
exposures to potentially toxic materials or harmful
physical agents and inform employees of the
monitoring results
✎ provide for employee walk-around or interview
of employees during the inspection process
✎ provide procedures for investigating alleged
violations, at the request of any employee or
employee representative issuing citations and
assessing monetary penalties against the employer
Hazard Communication
The intent of the OSHA Hazard Communication Standard
is to provide employees with information and training
about the potential health hazards from exposure to
workplace chemicals. The Standard requires that
employee training include:
✎ explanations of the requirements of the standard;
✎ identification of workplace operations where
hazardous chemicals are present;
✎ knowledge of the methods and observations used
to detect the presence of hazardous workplace
chemicals;
✎ assessment of the physical and health hazards of
those chemicals
✎ warnings about hazards associated with chemicals
in unlabelled pipes;
147
✎ descriptions of hazards associated with non-routine
tasks;
✎ details about the measures employees can take to
protect themselves against these hazards, including
specific procedures;
✎ explanation of the labelling system;
✎ instructions on location and use of material safety
data sheets (MSDSs);
✎ details on the availability and location of the hazardous
materials inventory, MSDSs, and other written hazard
communication material.
Hazard Warning and Symbols
Chemicals produced in the USA come under OSHA
Hazard Communication Standard. The label on the
container must warn about potential hazards of the
product. OSHA does not require hazard symbols on the
label, however, the skull and crossbones symbol is
acceptable on containers of highly toxic substances and
the flame symbol is acceptable on containers of
flammable substances.
