Asbestos
Background
Asbestos is a naturally occurring mineral which has commonly been used in a variety of
building materials due to its strength and unique fire and chemical resistant properties.
Intact and undisturbed asbestos presents no direct health hazard but does present a
potential exposure hazard should asbestos be released and taken into the body.
Asbestos fibres have been proven to cause disease when inhaled or ingested. The risk
of injury to health caused by the inhalation of asbestos is increased by smoking.
Holy Trinity School Division is committed to maintaining a safe and healthy environment
for all staff and students. The purpose of this plan is to provide staff with safe procedures
that must be followed in the event of any asbestos release in compliance with The
Occupational Health and Safety Regulations, 1996 (Part XXIII Asbestos Section 330345).
Occupational Health and Safety Regulations, 1996 require that Holy Trinity Roman
Catholic School Division #22 comply with the regulations set out in Part XXIII –
Asbestos. The regulations require that the Division:
• Identify all areas containing asbestos.
• Perform annual inspections.
• Repair asbestos surfaces.
• Provide notification of any asbestos removal processes.
• Educate employees at risk of encountering asbestos.
• Report any exposure to asbestos.
• Maintain records.

classified as a Type I procedure will be carried out by the school
caretaker.
2.3 The caretaker will contact the Supervisor of Facilities and
Transportation directly for emergency work required that would be of a
Type II or Type Ill nature and that work would be carried out by a
certified contractor.
3. Site Asbestos Management Binder
3.1 As part of the Asbestos Management Plan, it is mandatory to prepare and
maintain a record of all buildings owned and occupied within Holy Trinity
School Division which contain asbestos materials.
3.2 A site record will be established by means of a written report as well as a
current floor plan.
3.3 The report will show the extent and condition of the accessible asbestos
containing material in the building, the location of any samples taken as
well as the results of the analysis of the samples taken.
3.4 Any repairs, or abatement work will also be recorded.
3.5 The Asbestos Management Plan binder should be located in the office
and a copy should be kept by the Principal and available for all staff.
4. Annual Inspections
4.1 Annual Inspection must be done pursuant to section 336(1) of
Occupational Health and Safety Regulations, 1996, all friable asbestos
containing material and all sprayed on asbestos surfaces are inspected
annually by a competent person, to confirm that the material is not
releasing, and is not likely to release, asbestos dust into the atmosphere.
5. Classifications of Asbestos Work Operations
5.1 Work is to be classified into three categories, according to the likely risk of
exposure to asbestos that it presents.
Type I
May result in minimal exposure to asbestos fibres but should present
almost no risk of disease. Type I removal operations may involve the
following:
• the installation or removal of manufactured products containing
asbestos (i.e. ceiling tiles).
Holy Trinity Catholic School Division
Administrative Procedures Manual
500-39
•
•
•
the cutting, drilling, or shaping of manufactured products
containing asbestos
drywall removal where asbestos filler compound has been used
the use of power tools power tools equipped with a HEPA filter to
cut, grind asbestos containing materials
Type II
Work performed results in greater airborne concentrations of asbestos.
For minor disturbances or removal of friable material the classification is
Type II. Type II removal operations may involve the following:
• Removal of a false ceiling where a significant amount of friable
asbestos is likely to be lying on the surface of the false ceiling.
• Minor removal or disturbance of friable asbestos material during
the repair, removal, maintenance or alteration of equipment
• The enclosure or taping of piping or boiler insulation containing
asbestos
Type III
Will result in the highest asbestos fibre levels resulting in a high risk of
health effects. All major removals of friable material are classified as Type
Ill. For Type Ill operations and asbestos of a type other than chrysolite, a
powered air purifying dust respirator is required. If dry removal is
performed, a positive pressure supplied air respirator must be used. Type
Ill removal operations may involve the following operations:
• the removal other than minor removal of friable material containing
asbestos
• the spray application of a sealant to friable asbestos
• the cleaning or removal of air handling equipment that has
sprayed fireproofing containing asbestos
• the repair or demolition of a kiln, furnace or boiler made in part of
refractory materials containing asbestos
• the use of power tools not equipped with a HEPA filter used for
the use of asbestos containing materials
• the repair or demolition of any part of a building containing
asbestos, unless the asbestos was cleaned up and removed
6. Procedures to Follow for Repair/Removal
Should asbestos material that has been disturbed and/or deemed to be in need of
repair/removal that presents an immediate risk to students and staff, the following
procedures must be followed:
• Supervisor of Facilities and Transportation to be called immediately
• Area should be isolated and access restricted to maintenance and
contract personnel only
• Students to be relocated to another area until the site has been declared
safe
• All work to be recorded in the school Asbestos Management Plan binder
6.1 Type I operations may be carried out by Holy Trinity Catholic School
Division employees using the following procedure:
Holy Trinity Catholic School Division
Administrative Procedures Manual
500-40
Preparation of work area:
• Remove any visible dust from the surface of the work area with a
damp cloth or HEPA filter equipped vacuum.
• Use a drop sheet to control the spread of dust form the work area.
Removal Process:
• A wetting agent (water) must be applied to the material to be
repaired/removed unless the use of water will create a hazard.
Personal Protective Equipment:
• Use of a non-powered reusable or replaceable air purifying dust
respirator suitable for asbestos is recommended.
Clean-up:
• Discard waste in a 6 mil polyethylene disposable bag, identified as
containing asbestos waste, and seal with tape.
• Bag should then be place in a second clean and labelled bag and
again sealed with tape.
• Frequent clean­ up should be done at regular intervals by use of a
HEPA vacuum, by damp mopping, or by wet sweeping.
• Discard any contaminated drop sheets and coveralls upon completion
of work.
6.2 Type II it is recommended that type II work should be completed by
qualified contracted services.
Preparation of Work Area:
• Use drop sheets to control the spread of dust.
• Before work is initiated any friable material that is likely to be
disturbed and that is lying on the surface of the work area must be
removed and cleaned up by damp wiping or HEPA vacuuming.
• Visible warning signs indicating an asbestos project must be posted.
• Mechanical ventilation to the immediate area must be disabled, and
when possible, vents should be sealed off.
• If the work area is not enclosed by walls, it will be necessary to erect a
polyethylene enclosure surrounding the work area.
Removal Process:
• Unless wetting will create a hazard, water must be used to control
dust.
• When removing friable material, or when working above a false
ceiling, an enclosure surrounding the work area must be constructed
where practicable.
Personal Protective Equipment:
• For Type II operations a non-powered reusable or replacement air
purifying dust respirator suitable for asbestos is required.
• Disposable coveralls that do not permit the penetration of asbestos
Holy Trinity Catholic School Division

fibres must be worn by all workers in the work area. The coveralls
must have a snug fit at the wrists, ankles and neck, and must contain
a hood.
Clean-up:
• Discard waste in a 6 mil polyethylene disposable bag, identified as
containing asbestos waste, and seal with tape. Place this bag in a
second clean and labelled bag and seal with tape.
• Frequent clean-up must be done at regular intervals by use of a
HEPA vacuum, by damp mopping, or by wet sweeping.
6.3 Type III
Holy Trinity School Division employees will not undertake Type Ill activities.
This will be contracted out to contractors who are experienced with this level
of work. The work area will be designed so that there will be no need for
Board employees to require access to the work site except in emergency
situations or to inspect work.
7. Incident Report
Should an incident occur at the Facility a complete and accurate account must be
recorded on an Incident Report Form and kept in the Asbestos Management Plan
binder. A copy must also be sent to the Supervisor of Facilities and Transportation.
This is important to ensure proper procedure has been followed and to determine if
anything could have been done to avoid the incident in the first place.
