1.0 INTRODUCTION AND SCOPE
Western University owns sixty-eight buildings, seventeen of which have been sprayed
with Asbestos Containing Materials (ACM). Asbestos was once commonly used for
commercial and household applications. Asbestos was most frequently used because of
its fire-resistant properties, in both ships and buildings, as insulation wrapped around
heating pipes and boilers, in ceiling coatings, in thermal acoustic insulating boards, and
in cement cladding and pipes. In 1973, the use of asbestos in sprayed-on insulation was
prohibited in Ontario.
Asbestos is dangerous only if it is in a friable state (easily crumbled by hand pressure)
because loose fibres may be inhaled. If the asbestos is located in a traffic area, and if it
is easily moved or dislodged, there is a threat of exposure. If it cannot be disturbed, for
instance, if it is contained above a ceiling and in a good condition, or is a component in
an asbestos cement floor, the risk of exposure is considered negligible. Ontario's Royal
Commission examined the issues related to exposure to asbestos, including its use in
buildings. In its 1984 report on the Use of Asbestos, the Commission stated that "even
in those buildings which contain friable asbestos insulation, the possibility of a health
risk is largely limited to situations where work will disturb this asbestos."
Ontario Regulation 278 addresses asbestos use on construction projects and in building
and repair operations. It requires that when material containing asbestos has been used
in a building as fireproofing or in construction products, the owner must maintain a
record of that material and advise workers who might disturb the material. The owner
must have a training program for all workers who might work on or close to the material,
so they know of its hazards, how to use protective equipment, and what work practices
to follow. The owner must also inspect the material regularly to determine its condition.
The owner must also maintain the asbestos containing material in good condition.
Western University employs over 10,000 full time and part time employees, 100 of
whom routinely work in locations containing asbestos. Approximately 10 tonnes of ACM
waste is generated on the University's premises annually. The handling of this waste is
regulated by the Environmental Protection Act, Regulation 347. Large fines can be
levied to any generator if improperly disposing of ACM waste. The University doublebags all ACM waste in 6-mil polyethylene approved bags which are decontaminated
with a HEPA vacuum (High Efficiency Particulate Air Filter) before transporting to a
landfill site.
Program Scope
This program applies to all buildings and structures owned by Western University, to all
employees and students of the University, to occupants of University buildings and to
external organizations who may come into contact with or disturb any asbestos
containing material in University buildings.

2.0 DEFINITIONS
Asbestos
Asbestos is a generic term describing a number of naturally occurring fibrous, hydrated
mineral silicates that differ in chemical composition and are suitable for use as noncombustible, nonconducting and chemically resistant materials. Different types of
asbestos which may be found in buildings are chrysotile, amosite, and crocidolite.
Friable
Friable material means material that when dry can be crumbled, pulverized or powdered
by hand pressure, and includes such material that is crumbled, pulverized, or powdered.
Three types of friable material commonly used in buildings are:
 sprayed fibrous fireproofing
 decorative or acoustic texture coatings
 thermal pipe insulation (potentially friable)
HEPA
High Efficiency Particulate Air Filter
3.0 HISTORICAL INFORMATION
Identification of the Problem:
Asbestos Regulations were enforced in 1985 which were established to deal with
decades of neglect and lack of knowledge towards ACM. Many of the University's
buildings were built in the 1950's, at a time when the health hazards related to asbestos
exposure were not fully known. Most University maintenance staff had already worked
with, or in the vicinity of ACM. In the 1960's there was a sudden realization in North
American and Western European countries that an epidemic was occurring, affecting
mostly those who were working in the asbestos industry. Administration of many
workplaces reacted immediately to comply with the newly established governmental
regulations and moved towards documenting inventories of all ACM on their premises.
Part of this University Program includes training to ensure individuals working with ACM
have the skills and knowledge to properly follow procedures.
Target Personnel:
All personnel working in ceiling spaces, on ventilation systems and mechanical rooms
were identified by the University, together with the department which they operated
through. Directors and managers in charge of theses departments were contacted and
asked to supply a list of staff who may work in locations identified as containing friable
ACM. The staff were mostly skilled trades with varying asbestos-related experience.

4.0 OBJECTIVE OF THE ASBESTOS CONTROL PROGRAM
It is the objective of this asbestos control program to ensure that asbestos-containing
materials in University buildings are managed properly. The health of workers and
building occupants is safeguarded in accordance with the University Health and Safety
Policy and the “Regulation Respecting Asbestos on Construction Projects and in
Buildings and Repair Operations” made under the Occupational Health and Safety Act
of Ontario.
5.0 ASBESTOS CONTROL PROGRAM
Ontario Reg.278 "Regulation respecting Asbestos on Construction Projects and in
Buildings and Repair Operations", made under the Occupational Health and Safety Act
requires that the University maintain a management program with respect to asbestoscontaining materials in University buildings. The program documented here is intended
to meet the requirements of this regulation.
The basic elements of the control program are:
a. Identification and recording of the locations of all material containing
asbestos;
b. Frequent inspections of all asbestos-containing material to determine its
condition and repair of damage, and other remedial actions as appropriate;
c. The control of access to areas containing friable asbestos-containing
materials;
d. Training and education of workers who may disturb asbestos-containing
materials;
e. The provision of appropriate procedures for all asbestos-related work, and the
classification of such work as Type 1, 2, or 3 according to Ontario Reg. 278
f. The maintenance of records of Type 2 and Type 3 asbestos-related work;
g. Control and monitoring of external contractors performing work which may
disturb asbestos-containing materials;
h. Medical surveillance for workers who perform Type 2 and Type 3 asbestos
operations
i. Provision for auditing the implementation and effectiveness of the program;
and communication of this program and of asbestos related work taking place
in University buildings to the Joint Health and Safety Committees and to other
persons who may be affected by the work.
Asbestos-containing materials do not tend to become airborne unless damaged or
disturbed. ACM could be disturbed by water damage, maintenance activities, or
vandalism which could all increase the risk of generating significant airborne asbestos
fibre concentrations. To prevent this potential health hazard, an in-place management
program exists at the University. This management program includes periodic
5
inspections of the asbestos-containing materials and an assessment of the condition of
these materials. Repair of damaged asbestos-containing materials must be carried-out
by qualified personnel. The program includes the mechanical rooms where large
quantities of asbestos are present. In areas where damage and deterioration are found,
a plan and remedial action is implemented to repair the damage by taping, enclosing, or
by removal. The condition of the asbestos-containing material will dictate the urgency
and kind of remedial action necessary.
5.1 Maintenance Activities
Maintenance activities are performed when the affected area is unoccupied. If any ACM
has been dislodged during maintenance work, the affected area is cleaned with a
vacuum system equipped with HEPA filters. Accumulated dust is cleaned with a HEPA
vacuum, or by wet-mopping. Dry sweeping is not allowed as it causes lose fibres to
become airborne.
Maintenance workers are provided with and required to wear respirators approved by
the National Institute for Occupational Safety and Health (NIOSH). Each maintenance
worker is trained on the proper use and care of these respirators. Maintenance workers
are instructed on the potential health hazards of asbestos and on safe work practices.
5.2 Asbestos Abatement
If an area where ACM is being repaired it must be completely isolated from the rest of
the building. This may involve the construction of a temporary plastic barrier with an "air
lock" for worker entry. Ventilation in the area is shut off throughout the abatement.
Exhaust fans equipped with a HEPA filter may be used to place the affected area under
a slight negative pressure in relation to the rest of the building.
Workers in the area must wear the NIOSH-approved respirators, disposable coveralls
and caps. Warning signs are posted around the work area to warn people of the
dangers associated with the entry to the work area without wearing protective
equipment. Air testing is performed routinely around the abatement area to ensure that
asbestos fibres are not released into other areas in the building. Whenever possible, the
work area is wetted prior to any disturbance to reduce asbestos fibre release.
6.0 STANDARDS AND GUIDELINES
A number of standards and guidelines have been established for regulating exposure to
asbestos. These are found to protect workers who may, during the course of their work,
disturb the ACM. At the University, workers performing renovations, maintenance, and
janitorial activities receive instructions on the health hazards associated with the
6
exposure to asbestos fibres. These workers are made aware that exposure, or repeated
short exposures to airborne asbestos fibres can produce irreversible lung diseases.
In Ontario, regulations respecting asbestos made under the Occupational Health and
Safety Act call for specific strict measures. The Time-Weighted Average (TWA)
exposure of an unprotected worker to airborne asbestos shall not exceed 0.1 fibres/cc
(fibres per cubic centimetre of air) for any of the forms of airborne asbestos fibres. An
employee must take all necessary precautions and follow Western procedures to
ensure good work practices. Good hygiene practice dictates that airborne exposures in
unprotected occupied areas surrounding a removal project are maintained below
detection limits (0.01 fibres/cc).

INTRODUCTION
Many construction and insulation materials contain asbestos. These materials, if
removed, or disturbed in an uncontrolled manner, can release asbestos fibres into the
air, possibly causing a health hazard. The disturbance and mishandling of the
Asbestos-Containing Materials (ACM) can result from activities performed in close
proximity to, and not necessarily on asbestos-containing insulation materials. All
personnel working with, or in proximity to where there is a likelihood of disturbance to
the friable asbestos products must be informed by their supervisors of the known and/or
potential hazards associated with this exposure.
All asbestos-related work must be performed in accordance with the Ministry of Labour's
(MOL) Asbestos Regulations as a minimum. The work procedures must be safe for the
personnel involved, and for the environment, but also must be perceived as safe by the
public.
The University has established specific procedures and work practices which meet or
exceed this requirement (Work Procedure (WP) 10, 58 and 59 and the Ceiling Space
Access Policy). These can be obtained from Facilities Management.
PURPOSE
The Asbestos Control Policy is designed to provide information and guidelines for the
safe handling of Asbestos-Containing Materials (ACM) to promote awareness of its
presence and location in facilities at Western University. The goal is to ultimately
prevent incidents of uncontrolled disturbance.
20
RESPONSIBILITY
Compliance with this policy is the responsibility of the supervisors of personnel at all
levels within administrative, faculty, and ancillary operations, or supervisors of
contracted activities where workers may come in contact with ACM.
All uncontrolled asbestos-disturbance incidents must be reported immediately upon
discovery to the Occupational Health and Safety (OHS), or Facilities Management.
Completion of an incident report is also required from each affected person’s
supervisor. It is understood that Facilities Management and OHS will share any
information regarding such incidents as soon as possible after being notified.
Facilities Management has prepared and is maintaining an inventory of structural
asbestos for all affected Western buildings. Also, Facilities Management is responsible
for removal and/or clean up of asbestos as required. Facilities Management will also be
responsible for notifying OHS of all Type 3 Asbestos operations prior to the
commencement of any project.
It is the responsibility of OHS to assess any uncontrolled disturbance of ACM in any
University facility and to determine if further monitoring is necessary. OHS is also
responsible for compiling annual reports of asbestos exposure to the Ministry of Labour
and for providing information to the University community in the form of site visits,
consultation, documents, and training sessions.
CONTACTS
If you have any questions or concerns, contact Facilities Management at extension
83304, or Occupational Health and Safety at extension 88730.

relevant Facilities Management Work Procedures. In situations where these
written procedures do not address specific circumstances, appropriate measures
must be taken to control the release of asbestos fibres to protect all building
occupants. Both Facilities Management and OHS are to be consulted when such
matters arise.
(b) University staff and contractors shall not attempt to handle or work in close
proximity to ACM without first obtaining the Asbestos Awareness training, in
accordance with the Occupational Health and Safety Act, Regulation 278,
Section 19. Without proof of training, individuals will not be permitted to work on
or in close proximity to ACM. Training may be provided by OHS or other
recognized agencies.
(c) Access to all ceiling spaces must be performed in compliance with the
requirements outlined in the Ceiling Space Access Policy.
(d) Accompanying this policy are two related documents which further detail the
health hazard information that must be distributed to employees. i.e. Asbestos
Project Information Handout; and Asbestos Project Information
Guideline/Procedure.
(e) All University-generated ACM waste must be double-packaged in approved
asbestos bags, and transported to the designated waste-holding facilities on the
University’s premises at the completion of work. When required, this asbestos
waste must be transported to an approved landfill site and must be transported to
such site in compliance with Ontario Regulation 347 and the Transportation of
Dangerous Goods Act and Regulations.

APPENDIX 6: ASBESTOS HEALTH HAZARDS
42
43
Asbestos Health Hazards
Asbestos is a generic term referring to various fibrous mineral silicates, including
chrysotile (hydrated magnesium silicate), amosite (iron-magnesium silicate), crocidolite
(sodium-iron silicate), tremolite (calcium-magnesium silicate), anthophyllite (another
iron-magnesium silicate), and actinolite (calcium-magnesium-iron silicate).
The potential health hazards associated with exposure to asbestos result from
inhalation of airborne fibres; small asbestos fibres can pass readily through the upper
respiratory tract and be deposited in the terminal bronchioles of the lung. There the
fibres can produce a local irritation which the body attempts to overcome by initiating a
tissue response resulting in the encapsulation of the fibres and consequent formation of
"asbestos bodies." Asbestos fibres are the causative agents in cases of asbestosis, a
progressive disease characterized by diffuse interstitial fibrosis and, at times, pleural
changes of fibrosis and calcification. The disease is often evident by such clinical signs
as rales and dyspnea. In its severe form, asbestosis can contribute to, and result in,
death due to the inability of the body to obtain oxygen or the heart to pump blood
through the scarred lungs.
Exposure to airborne asbestos fibres has also been associated with bronchogenic
carcinoma (a malignancy of the interior of the lung), mesothelioma (a diffuse
malignancy of the lining of the chest cavity or abdomen), and cancer of the stomach,
colon and rectum. Cigarette smoking can enhance the incidence of bronchogenic
carcinoma from this substance.

METHOD OF ANALYSIS FOR ASBESTOS BULK USING POLARIZED LIGHT
MICROSCOPY (PLM)
When a bulk asbestos sample is received, several representative portions of the sample
are removed and put into a labelled Petri dish. The sample parts are examined through
a sterobinocular microscope and fibres are extracted using forceps. These extracted
fibres are then placed on a microscope slide and mounted using a refractive index
solution (high dispersion (HD) Cargille Liquid).
After mounting, the fibres are identified using polarized light microscopy (PLM),
supplemented by dispersion staining. After fibre identification by PLM, an estimation (+
or - 10%) is made as to the percent (area) composition of asbestos. The estimated
percentages are based on size, number, shape, and density of each of the components,
and comparison to a standard set of samples previously quantitated.

(Committee)
This corporate guideline/procedure is intended as a minimum requirement upon which
individual departments can build their own program directed at the specifics of their
activities.
Western University will provide information to all affected occupants on the known
health hazards of asbestos in the workplace environment.
Personnel working in proximity to Type 3 asbestos *projects where **friable AsbestosContaining Materials are known to exist will be informed as follows:
1. The work coordinator will provide an Asbestos Project Information Handout to the
supervisor(s) of personnel in the affected area at least two weeks prior to the
commencement of any project.
2. The work coordinator will also provide a 10-minute VHS video entitled “Asbestos
in School Buildings” to the same supervisor(s) for use during the entire duration
of the project.
3. supervisor(s) of the affected areas will be responsible for:
a. Distributing the “Asbestos Project Information Handout” to personnel in
affected areas.
b. Having the video “Asbestos in School Buildings” available for review by
concerned staff.
50
c. If required, a request for an Asbestos Information Seminar can be made
by the supervisor(s) in the affected area(s). This is available from the
Occupational Health and Safety, extension 88730.
Questions or concerns should be directed to Facilities Management at extension 83304,
or Occupational Health and Safety at extension 88730.
Type 3 Asbestos: Major friable asbestos disturbance.
*Projects: Construction, renovations, or maintenance activities where friable asbestoscontaining materials are present.
** Friable Material: Material that when dry can be crumbled, pulverized or powdered by
hand pressure and includes such material that is crumbled, pulverized, or powdered.

WESTERN UNIVERSITY
ASBESTOS PROJECT INFORMATION HANDOUT
Western University ensures that all asbestos removal procedures, ceiling space entry, and
maintenance activities in areas containing Asbestos-Containing Materials (ACM) are performed
in such a way as to prevent the spread of asbestos dust/debris and in accordance with
governmental procedures and regulations.
Advanced notice will be provided by the project coordinator / supervisor to affected occupants.
The notice shall include information on the anticipated duration of the project, type of work, and
name of the group performing the work. All personnel working with or in proximity to friable
asbestos projects will be informed of the known and / or potential hazards associated with the
exposure to asbestos.
A VHS video addressing the issues of asbestos in school buildings is available for
review through your supervisor.
Maintenance or contracted personnel doing work on or near ACM, will adopt those controls that
are appropriate to the type of work being done and as listed below:
1. Post the area with asbestos hazard signs.
2. Where classification of work requires it, disable the ventilation system serving the work
area, and seal the ventilation ducts to and from the work area.
3. Install polyethylene enclosure (or utilize a portable enclosure) around the affected area
to prevent the spread of ACM.
4. Wear personal protective equipment as prescribed to protect against the exposure to
asbestos.
5. Maintain proper controls in the work area to prevent the release of ACM outside of the
work area.
6. During, and immediately upon completion of the work, vacuum all exposed surfaces with
asbestos vacuums and double-bag the waste with 6-mil polyethylene bags.
During major asbestos disturbance projects (Type 3), a qualified Safety Officer or inspecting
agency will monitor the air in and around the affected area. Monitoring of the air will be
performed before, during, and immediately after the completion of the project. All samples will
be analyzed by an accredited laboratory.
Since the enclosure of the work area is designed to prevent the spread of asbestos fibres,
personnel working outside the enclosed area may continue to work in a normal manner.
However, they should note that:
(a) access to the enclosed area is restricted to trained persons only wearing protective
clothing and equipment.
(b) evidence of dust/debris created by the work and /or lack of enclosure should be reported
to the supervisor in charge or by calling the numbers below.
If you have any questions or concerns contact Facilities Management at extension 83304 or
Occupational Health and Safety at extension 88730.
