and Health (NIOSH) method 7400, except work in British Columbia and Quebec,
where provincial analytical methods are in place.
Analysis of PCM samples shall be performed by Health Canada or individuals or
organizations successfully participating in a recognized external quality control
program.
Bulk Sample Collection and Analysis
Procedures for collection and labeling of bulk samples for asbestos analysis are
detailed in Appendix 6 - Work Procedures.
Analysis of materials to determine asbestos content shall be performed by Health
Canada or by private laboratories accredited by the National Voluntary
Laboratory Accreditation Program (NVLAP) of the U.S. National Institute of
Science and Technology (NIST). The laboratories shall report to the limits of
detection as indicated in Appendix 1 - Detection Limit of Bulk Analysis.
Maintenance of Records
The Regional Asbestos Coordinator shall maintain copies of all reports and
records relating to testing, sampling and analysis undertaken for buildings and
facilities within the region.
10. Hazard Investigation
When an employee is or may be exposed to airborne asbestos as a result of
direct disturbance of asbestos materials during maintenance, renovation or
construction work not subject to the appropriate precautions required by the
Asbestos Code of Practice, or by similar inadvertent direct contact not subject to
the appropriate precautions, the Regional Asbestos Coordinator shall appoint a
qualified person to conduct a hazard assessment. This assessment must
consider the potential hazard, and must conclude as to whether the hazardous
material could be present.
The Regional Asbestos Coordinator shall notify, in writing, the Workplace Safety
and Health Committee or Representatives of this assessment.
The assessment shall determine the potential hazard, and must conclude as to
whether the hazardous material could be present as an airborne hazard, at a
level of at least 50% of the exposure limit. When it has been determined that the
hazardous material could be present at a level of at least 50% of the exposure
limit, a control plan must be instituted.
Control Plans for Asbestos
When an assessment has determined that asbestos could be present as an
airborne hazard, at a level of at least 50% of the exposure limit, a control plan
must be established and implemented to address the following requirements:




a record of where asbestos materials are located;
written procedures for control;
medical surveillance, when applicable;
training of employees.
The control plan must be reviewed at least once per year, or as new information
is received that changes the requirements of the plan.
Annex C - Appendix 1 - Evaluation of Asbestos Containing Materials (ACM) and
Recommendations for Control
1. Assessment of Condition
Spray Applied Fireproofing, Insulation and Texture Finishes
In evaluating the condition of ACM spray applied as fireproofing, thermal
insulation or texture, decorative or acoustic finishes, the following criteria apply:
GOOD Surface of material shows no significant signs of damage,
deterioration or delamination. Up to one percent visible damage to
surface is allowed within range of GOOD. Evaluation of sprayed
fireproofing requires the surveyor to be familiar with the irregular
surface texture typical of sprayed asbestos products. GOOD
condition includes unencapsulated or unpainted fireproofing or
texture finishes, where no delamination or damage is observed, and
encapsulated fireproofing or texture finishes where the encapsulation
has been applied after the damage or fallout occurred.
POOR Sprayed materials show signs of damage, delamination or
deterioration. More than one percent damage to surface of ACM
spray.
In observation areas, where damage exists in isolated locations, both GOOD and
POOR condition may be reported. The extent or percentage of each condition will
be recorded on the survey or reassessment form.
NOTE: FAIR condition is not utilized or considered as a valid criterion in the
evaluation of sprayed fireproofing, sprayed insulation, or texture coat finishes.
The evaluation of ACM spray applied as fireproofing, non-mechanical thermal
insulation, or texture, decorative or acoustic finishes which are present above
ceilings, may be limited by the number of observations made, and by building
components such as ducts or full height walls that obstruct the above ceiling
observations. Persons entering the ceiling area are advised to be watchful for
ACM DEBRIS prior to accessing or working above ceilings in areas of buildings
with ACM, regardless of the reported condition.
Mechanical Insulation
In evaluating the condition of mechanical insulation (on boilers, breeching,
ductwork, piping, tanks, equipment etc.) the following criteria are used:
GOOD Insulation is completely covered in jacketing and exhibits no evidence
of damage or deterioration. No insulation is exposed. Includes
conditions where the jacketing has minor surface damage (i.e., scuffs
or stains), but the jacketing is not penetrated.
FAIR
Minor penetration damage to jacketed insulation (cuts, tears, nicks,
deterioration or delamination) or undamaged insulation that has
never been jacketed. Insulation is exposed but not showing surface
disintegration. The extent of missing insulation ranges should be
minor to none.
POOR Original insulation jacket is missing, damaged, deteriorated or
delaminated. Insulation is exposed and significant areas have been
dislodged. Damage cannot be readily repaired.
The evaluation of mechanical insulation may be limited by the number of
observations made and building components such as ducts or full height walls
that obstruct observations. In these circumstances, it is not possible to observe
each foot of mechanical insulation from all angles.
Non-Friable and Potentially Friable Materials
Non-friable materials generally have little potential to release airborne fibres,
even when damaged by mechanical breakage. However, some non-friable
materials, i.e., exterior asbestos cement products, may have deteriorated so that
the binder no longer effectively contains the asbestos fibres. In such cases of
significantly deteriorated non-friable material, the material will be treated as a
friable product.
2. Evaluation of Accessibility
The accessibility of building materials known or suspected of being ACM is rated
according to the following criteria:
ACCESS (A)
Areas of the building within reach (from floor level) of all building
users. Includes areas such as gymnasiums, workshops, and
storage areas where activities of the building users may result in
disturbance of ACM not normally within reach from floor level.
ACCESS (B)
Frequently entered maintenance areas within reach of
maintenance staff, without the need for a ladder. Includes:
frequently entered pipe chases, tunnels and service areas or
areas within reach from a fixed ladder or catwalk, i.e., tops of
equipment, mezzanines.
ACCESS (C)
EXPOSED
Areas of the building above 8'0" where use of a ladder is required
to reach the ACM. Only refers to ACM materials that are exposed
to view, from the floor or ladder, without removing or opening
other building components such as ceiling tiles, or service access
doors or hatches. Does not include infrequently accessed service
areas of the building.
ACCESS (C) Areas of the building which require the removal of a building
CONCEALED component, including lay-in ceilings and access panels into solid
ceiling systems. Includes rarely entered crawl spaces, attic
spaces, etc. Observations are limited to the extent visible from
the access points.
ACCESS (D)
Areas of the building behind inaccessible solid ceiling systems,
walls, or mechanical equipment, etc., where demolition of the
ceiling, wall or equipment, etc., is required to reach the ACM.
Evaluation of condition and extent of ACM is limited or
impossible, depending on the surveyor's ability to visually
examine the materials in Access D.
3. ACM Debris
Debris from Friable ACM
The presence of fallen ACM is noted separately from the presumed friable ACM
source (sprayed fireproofing, thermal insulation, texture, decorative or acoustic
finishes or mechanical insulation) and is referred to as DEBRIS.
Debris from Damaged Non-Friable ACM
The presence of fallen ACM, from damaged non-friable ACM, is reported
separately from the non-friable ACM source. Only fallen non-friable ACM, that
has become friable, is reported as DEBRIS.
The identification of the exact location or presence of DEBRIS on the top of
ceiling tiles is limited by the number of observations made and the presence of
building components such as ducts or full height walls that obstruct observations.
Workers are advised to be watchful for the presence of DEBRIS prior to
accessing, or working in proximity to, mechanical insulation or above ceiling
areas of buildings with ACM, regardless of the reported presence or absence of
DEBRIS.
4. Action Matrix and Action Descriptions
The Asbestos Management Program requires the following responses:


Immediate clean-up of DEBRIS that is likely to be disturbed;
The removal, repair or enclosure of friable ACM in POOR or FAIR
condition where continued deterioration will result in DEBRIS that is likely
to be disturbed.
The following factors shall be considered in making site-specific
recommendations for compliance with the regulation, and for the practical
implementation of asbestos management:
3. ACM in POOR condition is not routinely repairable.
If an abatement action is necessary, removal is the recommended action
(enclosure is a viable option in unusual circumstances).
4. Mechanical insulation in FAIR condition will be repaired or removed
based on the following general recommendations, applied on a case by
case basis.
Repair ACM mechanical insulation found in FAIR condition in ACCESS
(B) or ACCESS (C) EXPOSED areas.
Remove ACM mechanical insulation found in FAIR condition in ACCESS
(B) and ACCESS (C) EXPOSED areas, where future damage to the
ACM is likely to occur.
5. ACM in GOOD condition present in ACCESS (A) can be managed by
surveillance, as long as it is not disturbed by future renovation,
maintenance or demolition. Proactive removal of the ACM in ACCESS
(A) will be considered where damage is possible by ongoing occupant
activity (accidental or intentional).
6. Non-friable or manufactured products are considered in the action matrix
as follows:
 Non-friable and manufactured products reported in POOR
condition, or friable DEBRIS resulting from the deterioration of
non-friable ACM, are treated as friable materials and the
appropriate Action, depending on accessibility, is determined
from the Action Matrix for friable ACM.
 For non-friable or manufactured products reported in GOOD
condition, Action 7 (surveillance) is recommended regardless of
Accessibility.
7. Remove all ACM from a particular area where small quantities of
asbestos are present and removal will negate the need for the use of the
Asbestos Management Program in that area.
The Action Matrix provided below establishes the recommended
asbestos control action. The ACTIONS are described in full following the
matrix.

Remove ACM in ACCESS (B)/FAIR condition if ACM is likely to be disturbed.
ACTION 1 Immediate Clean-up of Debris That is Likely to be Disturbed
Restrict access that is likely to cause a disturbance of the ACM
DEBRIS and clean up ACM DEBRIS immediately. Utilize correct
asbestos procedures. This action is required for compliance with
regulatory requirements. The surveyor should immediately notify
the Regional Asbestos Coordinator of this condition.
ACTION 2 Entry Into Areas With ACM Debris - Type 2 Precautions
At locations where ACM DEBRIS can be isolated in lieu of
removal or cleaned up, use appropriate means to limit entry to the
area. Restrict access to the area to persons utilizing Type 2
asbestos-work precautions. The precautions will be required until
the ACM DEBRIS has been cleaned up, and the source of the
DEBRIS has been stabilized or removed.
ACTION 3 ACM Removal Required for Compliance
Remove ACM for compliance with regulatory requirements. Utilize
asbestos procedures appropriate to the scope of the removal
work.
ACTION 4 Access into Areas Where ACM is Present and Likely to be
Disturbed by Access - Type 2 Precautions
Use Type 2 asbestos precautions when entry or access into an
area is likely to disturb the ACM. ACTION 4 must be used until
the ACM is removed (Use ACTION 1 or 2 if DEBRIS is present).
ACTION 5 Proactive ACM Removal
Remove ACM in lieu of repair, or at locations where the presence
of asbestos in GOOD condition is not desirable.
ACTION 6 ACM Repair
Repair ACM found in FAIR condition, and not likely to be
damaged again or disturbed by normal use of the area or room.
Upon completion of the repair work, treat ACM as material in
GOOD condition and implement ACTION 7. If ACM is likely to be
damaged or disturbed, during normal use of the area or room,
implement ACTION 5.
ACTION 7 Routine Surveillance
Institute routine surveillance of the ACM. Trained workers or
contractors must use appropriate asbestos precautions (Type 1,
Type 2 or Type 3) during disturbance of the remaining ACM.
5. Detection Limit of Bulk Analysis
Asbestos containing material, (ACM), is defined as any material found to contain
asbestos at or above the limit for an asbestos containing material, (ACM), set
provincially, as determined by the standard Polarized Light Microscopy method
for the analysis of bulk samples. The provincially regulated limits, or generally
accepted guidelines, to consider a material as an asbestos containing material,
(ACM), subject to asbestos in buildings regulation, is provided as follows:

Annex C - Appendix 6 - Work Procedures
TYPE 1 - Work Procedures
For locations of non-friable ACM, refer to the current version of the Asbestos Inventory and
Assessment Report.
NOTE: These Type 1 procedures assume the non-friable material can be removed with relatively
little loose dry dust released. Generation of debris is permissible as long as the debris can be well
wetted before being removed. If the work will release more than a trivial amount of dry loose dust,
do not proceed. The Regional Asbestos Coordinator will determine which of Type 1, 2 or 3
procedures are appropriate.
1.
Equipment
All equipment must be on site before proceeding.
1. Vacuum
Use of a vacuum is optional. Wet cleaning methods may be used in place of a
vacuum. If a vacuum is used it must be equipped with a high efficiency particulate
(HEPA) filter and all brushes, fittings, etc. The vacuum must only be opened in an
enclosure, following Type 2 procedures, or in a laboratory exhaust hood. The
vacuum exterior should be carefully wet cleaned after emptying. A HEPA filter is at
least 99.97% efficient in collecting a 0.3 micrometre particle.
2. Respirators
Use of a respirator is optional for Type 1 work. However, a respirator is strongly
advised for work on sheet flooring, any type of ceiling tile, any other work performed
overhead. Respirators shall be supplied by the employer upon request. The type of
respirator supplied shall be a half-face respirator with HEPA filter. Training in the
proper use of the respirator and qualitative fit testing shall also be provided.
Respirators must be NIOSH approved and acceptable to the Provincial Authorities
having jurisdiction. Respirators shall be used according to the written procedures
for use, provided to the worker during training sessions. Filters must be changed
after 24 hours of wear, or sooner if breathing resistance increases.
NOTE: Employees are required to undertake a medical evaluation as specified by
DP 059 - Health Evaluations - Safety and Health, PWGSC prior to being trained in
the proper use of respirators.
3. Protective Clothing
Reusable or disposable clothing may be used. Non-disposable clothing with visible
asbestos contamination shall be cleaned with a HEPA vacuum and laundered as
asbestos contaminated. Disposable clothing and respirator filters will be disposed of
as asbestos waste.
4. Other Equipment
 plastic sheet (0.15 mm (6 mil) polyethylene) - to serve as a drop sheet;
 pump sprayer with mister nozzle, or alternate method to wet material;
 labelled, yellow asbestos waste bags, 0.15 mm (6 mil) - for all asbestos
waste, disposable equipment, plastic, etc.;
 small tools and cleaning supplies - e.g., scouring pads, sponges, brushes,
buckets, etc.
2.
Other Protective Measures
1. Do not eat, drink or smoke in the work area.
2. On leaving work area, proceed to washroom and wash all exposed skin on hands
and face.
3.
Preparation
1. Before disturbing non-friable asbestos materials, (wherever practical) cover floor
and surfaces below work with polyethylene sheeting to catch debris.
2. Wherever dust on a surface is likely to be disturbed, remove with HEPA vacuum or
damp cloth.
4.
Execution
1. Removal of Vinyl Asbestos Floor Tile
1. Do not use electric powered scrapers.
2. Start removal by wedging a heavy duty scraper in seam of two adjoining
tiles and gradually force edge of one tile up and away from floor. Do not
break off pieces of tile, but continue to force balance of tile up.
3. Continue removal of tiles using hand tools, removing tiles intact wherever
possible. When adhesive is spread heavily or is quite hard, it may prove
easier to force scraper through tightly adhered areas by striking scraper
handle with a hammer using blows of moderate force while maintaining
scraper at 25° to 30° angle to floor. When this technique does not loosen
tile, removal can be simplified by heating tile thoroughly with a hot air gun
until heat penetrates through tile and softens the adhesive.
4. As each tile is removed, place into asbestos waste receptor. Do not break
into smaller pieces.
5. After removal of a small area, scrape up adhesive remaining on floor with a
hand scraper until only a thin smooth film remains. Where deposits are
heavy or difficult to scrape, a hot air gun may be used. Deposit scrapings in
the asbestos waste disposal bag. Do not dry scrape surface pieces of tile
that remain adhered. Do not use powered electric scrapers.
6. On completion of the area, vacuum clean floor with HEPA vacuum or wet
mop. Dispose of the mop head as contaminated waste.
2. Removal of Asbestos-Containing Sheet Flooring
1. Remove binding strips or other restrictive mouldings. Workers shall wear air
purifying respirator fitted with high efficiency filter, and coveralls, at all
times.
2. Make series of cuts 100 mm to 200 mm (4" to 8") apart through top layers
and about halfway through felt backing, parallel to wall.
3. Start at end of room furthest from door and pry up corner of strip,
separating top sheet from backing layer. Pull top layer back upon itself
slowly and evenly, and half backing and top layers should pull free. After it
is removed, roll up strip face out into tight roll, tape or tie securely, and
place into asbestos waste receptor. Wet the asbestos felt underlay
remaining on floor as soon as exposed.
4. Continue with successive strips. Avoid walking on exposed asbestos felt.
Seal asbestos waste receptors when filled. Remove maximum of three
strips before wet scraping exposed felt underlay.
5. Remove remaining adhered underlay by wet scraping. Soak area with
water applied by sprayer. Allow water to penetrate felt. Scrape off
remaining material. Maintain material wet by applying more water. Place
scrapings in asbestos waste receptor.
6. Continue this procedure alternately removing top sheets and then wet
scraping felt, three strips at a time. Be careful not to walk on stripped floor.
7. When whole floor has been cleaned of asbestos felt, allow it to dry and
vacuum up any dirt with a HEPA vacuum or wet mop. Do not dry sweep.
Dispose of the mop head as contaminated waste.
8. Thoroughly clean tools and equipment with a damp cloth before returning to
regular service. Dispose of cloth as contaminated waste.
3. Installing, Cutting or Drilling Non-Friable Asbestos Materials
1. Work using power tools not fitted with HEPA filter dust collectors, must not
be performed as Type 1 work.
2. Where possible wet all materials to be disturbed.
3. Immediately place waste in asbestos waste receptor. Clean area frequently
during work with HEPA vacuum or by wet methods.
4. At completion of work, drop sheets that will be reused must be cleaned with
HEPA vacuum or by wet methods.
5. Drop sheets that will not be reused must be disposed of as asbestos waste.
4. Removal of Other Non-Friable Asbestos Materials
1. Type 1 procedures apply only to materials which can be removed intact, or
in sections, without producing a pulverized or powdered waste. This
method is most applicable to asbestos-cement board products, acoustic
ceiling tiles, gaskets, etc.
2. Where possible wet all material to be disturbed.
3. Undo fasteners necessary to remove material. Whenever possible remove
asbestos cement panels intact. Break only if unavoidable. If broken, wet
freshly exposed edges.
4. Where sections are adhered to the substrate, wet material and use hand
scraping to remove adhering material.
5. Place removed material into asbestos waste receptor. Clean surrounding
surfaces and asbestos work area frequently with HEPA vacuum or with wet
methods (i.e., damp cloth that is disposed of as asbestos waste after
cleaning).
6. Drop sheets shall be disposed of as asbestos waste.
5.
Waste Transport and Disposal
1. Place waste into asbestos labelled disposal bag, seal with tape, clean the exterior
of the bag with a clean cloth, and place into a second clean bag, also to be sealed
with tape. Use a barrel, fibre drum, or cardboard or wooden box in place of the
second bag when the asbestos waste material is likely to tear the inner bag. Seal
the outer container.
2. Place waste containers in storage area for holding asbestos waste. Containers shall
be labelled and assigned exclusively for asbestos waste.
3. Prepare waste for disposal in compliance with provincial regulations. The Property
Manager will arrange for disposal.
TYPE 2 - Work Procedures
For locations of asbestos materials, refer to the current version of the Asbestos Inventory and
Assessment Report.
1.
Equipment
Equipment required for the work must be on-site before proceeding.
1. Vacuum
An asbestos-approved vacuum (HEPA filtered), equipped with brushes, fittings, etc.
Vacuum must not be opened except by a fully protected worker within a Type 2
enclosure. The vacuum exterior shall be carefully wet cleaned after emptying. A
HEPA filter is at least 99.97% efficient in collecting a 0.3 micrometre particle.
2. Respirators
Workers within the work area shall wear approved respirator. Respirators and filters
will be provided by the employer, and individually assigned to workers. Respirator
shall be a half-facepiece respirator with high efficiency filters. Respirators must be
NIOSH approved and acceptable to the Provincial Authorities having jurisdiction.
Respirators shall be kept in position throughout the entire time the worker is in the
area of the work, from first disturbance of a ceiling tile or asbestos material, until the
final cleaning of the area and bagging of waste is complete. Change filters after 24
hours of wear or sooner if breathing resistance increases.
3. Protective Clothing
All workers shall wear disposable coveralls with attached elasticized hood.
Coveralls should be worn with the hood in place at all times. Coveralls may be
vacuumed or wet wiped clean for reuse, for a maximum of 8 hours cumulative wear.
Suit and head cover shall remain in place until worker leaves work area or the
enclosure is dismantled. Boot covers or dedicated boots are recommended.
4. Other Equipment
 plastic sheet (0.15 mm (6 mil) polyethylene) - to erect a total enclosure or to
serve as drop sheet;
 wood framing or clips to support polyethylene sheeting, as appropriate to
work area;
 tape - to fasten plastic enclosure to ceiling or to tape drop sheet to floor; ¾"
double-sided tape recommended for attaching polyethylene to T-bar ceiling;
 labelled asbestos waste bag 0.15 mm (6 mil) - for all asbestos waste,
disposable suit, plastic for disposal, etc.;
 pump sprayer containing water with wetting agent to wet asbestos as
necessary (dilute wetting agent as per manufacturer's recommendations);
 asbestos warning signs;
 cleaning supplies - e.g., scouring pads, sponges, brushes, buckets, etc.;
 insulation repair supplies (lagging compound, cloth, PVC covers);
 encapsulating sealer, for brush or airless spray application.
2.
Other Protective Measures
1. Do not eat, drink or smoke in the work area.
2. On leaving work area, proceed to washroom and wash all exposed skin on hands
and face.
3.
Scheduling of Work
1. Schedule work when occupants are absent. If persons are present, do not start
work.
2. If work above ceiling is required on an emergency basis, and the area is occupied,
ensure that client department(s) advise occupants to vacate area until work is
complete and clearance is given to return.
4.
Preparation
1. Shut down ventilation systems to and from the work area. Seal over all ventilation
openings, diffusers, grilles, etc., with plastic and tape.
2. Where practical, clear areas of movable furnishings or equipment. This should
include anything that occupants may wish to use during work period. Any
furnishings or equipment not removed shall be adequately covered and sealed
using 0.15 mm (6 mil) polyethylene and tape. The intent of the protection is to
provide an airtight envelope to protect the articles from airborne dust or splashed
debris.
3. Post signs or barrier tape, appropriate to the work area, to indicate asbestos hazard
and requirement for protective clothing for anyone entering the space.
4. For small rooms, cover walls with plastic such that the complete room becomes the
work area. For larger rooms, erect enclosure of 0.15 mm (6 mil) polyethylene, of
suitable dimensions to enclose the work area, and scaffolds and ladders required to
gain access. If a suspended ceiling is present, the enclosure shall extend to the
ceiling line. The enclosure shall be as airtight as conditions permit, and will include
the provision of a double overlapping flap at the entrance. The floor of the work
area shall be a layer of 0.15 mm (6 mil) polyethylene sealed to the plastic walls of
the enclosure.
5. Don protective clothing and respirator prior to removing ceiling tile or disturbing pipe
jacketing or sprayed fireproofing.
5.
Execution
1. To remove fireproofing or texture plaster, saturate with amended water solution,
using a pump sprayer. Do not remove the asbestos material until the material is
thoroughly wetted to the substrate. Do not use water where electrical hazard exists.
2. To remove pipe insulation, first wet any area of damage, then carefully cut jacket.
Keep insulation surface wetted by mist of water with wetting agent. Remove
insulation in large sections and place immediately in disposal bag. After large
pieces have been removed, saturate debris on mechanical equipment and clean all
exposed surfaces with abrasive pads, sponges, cloths, etc.
3. To repair pipe insulation, use drop sheet under area of work to aid clean-up of any
dislodged material. Plastic enclosure is not required. Mist any exposed insulation to
wet surface and apply lagging paint and canvas or PVC jacketing as required.
4. For removal of suspended ceiling tiles (where asbestos debris is present on top of
tiles or equipment to be accessed), remove the first tile carefully and vacuum all
surfaces. Vacuum the upper surface of each subsequent tile prior to removal. Store
tiles in the work area.
5. Remove dust and loose friable material likely to be disturbed in the process of doing
the work, with a HEPA vacuum or by damp wiping.
6. When asbestos material is removed, all pieces should be placed directly into 0.15
mm (6 mil) polyethylene bags as they are removed. Avoid dropping material to floor
wherever possible. After bulk removal is complete, wet wash the exposed surface.
7. Frequently, and at regular intervals during the work, clean up dust and waste in the
work area by wet mopping, placing in disposal bags, or by HEPA vacuuming.
8. After completion of removal, seal exposed ends of fireproofing, texture plaster, or
mechanical insulation with heavy layer of encapsulating sealer. Apply sealer coat to
surfaces from which asbestos material was removed.
9. At completion of work, decontaminate equipment, tools and materials used in the
work area by wet cleaning or HEPA vacuum.
10. Dispose of drop sheets and enclosures by wetting the polyethylene, then folding
into disposal bags. Do not reuse drop sheets or enclosures.
11. Before leaving work area, decontaminate shoes and protective clothing by using
HEPA vacuum or damp wiping. When protective clothing is to be disposed of, it
shall be decontaminated as above and placed in labelled disposal bags. Workers
shall vacuum all exposed skin, suit and respirator, and proceed to nearest
washroom to wash hands and face.
6.
Waste Transport and Disposal
1. Place waste into asbestos labelled disposal bag, seal with tape, clean the bag, and
place into a second clean bag, also to be sealed with tape. Use a barrel, fibre drum,
or cardboard or wooden box in place of the second bag when the asbestos waste
material is likely to tear the inner bag. Seal the rigid outer container.
2. Place waste containers in storage area for holding asbestos waste. Containers shall
be labelled and assigned exclusively for asbestos waste.
3. Prepare for waste disposal in compliance with provincial regulations. The Property
Manager will arrange for disposal.
TYPE 3 - Work Procedures
Type 3 procedures are not included in the standard work procedures due to the requirement for
the development of specific procedures for the site and for the particular circumstances.
Glove Bag Work Procedures
1.
Equipment
All equipment must be on site before proceeding with the work. Note that these procedures
are primarily based on the use of Safe-T-Strip polyvinyl chloride movable glove bags. (Only
the Safe-T-Strip glove bag is permitted for use in Ontario.) If the single use polyethylene
glove bags permitted in some other jurisdictions are used, it should be understood that they
are for use at one location only, and cannot be moved or used elsewhere.
NOTE: If single use polyethelene glove bag is used Section 5 - Execution, shall be replaced
by manufacturer's recommended procedures.
1. Glove Bag
Prefabricated, 0.25 mm (10 mil) minimum thickness polyvinyl-chloride bag with
integral 0.25 mm (10 mil) thick polyvinyl-chloride gloves and elasticized port. Bag
shall be equipped with reversible double-pull double throw zipper on top. Bag must
incorporate internal closure strip if it is to be removed from pipe for reuse
elsewhere. Provide size and configuration appropriate for insulation to be removed.
The bag must be disposed of once filled. Bag shall not be emptied and reused.
2. Securing Straps
Reusable nylon straps at least 25 mm (1") wide with metal buckle for sealing ends
of bags around pipe and/or insulation.
3. Water Sprayer
Garden reservoir type, low velocity, capable of producing mist or fine spray with
water-containing wetting agent. Wetting agent shall be diluted as per
manufacturer's recommendations.
4. Respirators
Workers using glove bag must wear approved respiratory protection. Respirators
and filters must be provided by the employer, and individually assigned to workers.
Respiratory protection must be equal to, or exceed, protection of half-face respirator
with high efficiency filters. Respirators must be NIOSH approved and acceptable to
the Provincial Authorities having jurisdiction. Respirators shall be kept in position
from the time the worker is attaching bag to pipe until final cleaning of the pipe and
bagging of waste is completed. Filters shall be changed after 24 hours of wear or
sooner if breathing resistance increases.
5. Protective Clothing
Workers shall wear disposable coveralls with attached elasticized hood. Coveralls
and hood shall remain in place until worker completes cleaning of pipe. Suit may be
cleaned for reuse or disposed of as asbestos waste.
6. Other Equipment
 labelled asbestos waste bags 0.15 mm (6 mil) - for all asbestos waste in
glove bag, disposable suit, cleaning materials, etc.;
 asbestos warning signs;
 wire saw - saw with flexible serrated wire blade and handles to allow use
inside glove bag;
 knife with fully retractable blade for use inside glove bag;
 plastic sheet (4 mil polyethylene) to cover exposed or damaged section of
pipe prior to attaching glove bag;
 tape-to fasten plastic to pipe if required;
 cleaning supplies e.g., scouring pads, sponges, brushes, buckets, etc.;
 HEPA vacuum, for evacuating air from bag prior to removing bag from pipe.
A HEPA filter is at least 99.97% efficient in collecting a 0.3 micrometre
particle.
2.
Other Protective Measures
1. Do not eat, drink or smoke in the work area.
2. On completing clean-up of work area, use HEPA vacuum or wet cloth to clean
hands, face, respirator and boots. Remove protective equipment and proceed to
nearest washroom to wash all exposed skin on hands and face.
3.
Scheduling of Work
1. Schedule work when occupants are absent. If persons are present, do not start
work.
4.
Preparation
1. Where practical, clear area below pipe of moveable furnishings or equipment.
Provide scaffold as required to reach pipe.
2. Post an asbestos warning sign at all entrances to room in which the procedure is
being used. If necessary use rope or tape barriers to separate work area.
3. Segregate the area of asbestos work, from other parts of the building required to
remain in use by using polyethylene walls or barrier tape.
4. Shut off and seal all diffusers, vents and other openings to ventilation and exhaust
systems in the room with polyethylene secured with tape.
5. Cover all items or equipment located in the designated work area with polyethylene
when items or equipment cannot be cleaned in the case of a spill. Tape the
polyethylene in place. The polyethylene should cover a width equal to the height of
the pipe from the floor, with a minimum width of 3.6 m (12 feet), where required.
6. Seal all openings and voids in the vicinity of the glove bag operation with one layer
of polyethylene secured with tape.
7. Check condition of pipe insulation where work will be performed. If the pipe
insulation has minor isolated damage, mist surface and patch with tape. If damage
is more extensive, wrap pipe with plastic and "candy stripe" it with duct tape first. If
pipe insulation is severely damaged and cannot be simply repaired, glove bag is not
appropriate. (Use Type 2 Procedures.)
8. Pre-clean with HEPA vacuum or wet methods any loose material on surface of pipe
or any material on the floor. If significant amount of material is on floor, Type 2
procedures may be required for clean-up. (See Type 2 Procedures.)
9. Place necessary tools in bottom of glove bag.
5.
Execution
1. Zip the bag onto the pipe and seal each end to the pipe with the securing straps. Do
not pull the bag tightly to the ends - a small amount of slack allows better room to
work within the bag. If a vertical bag is in use, ensure lower strap passes through
plastic grommet and cloth tab on zipper.
2. Place hands into gloves and use necessary tools (wire saw, utility knife, wire
cutters) to remove insulation from pipe. Arrange insulation in bottom of bag to
obtain full capacity of bag. Roll metal jacketing carefully to minimize ripping or
puncturing of the bag.
3. Insert nozzle of spray pump into bag through valve and wash pipe and interior of
upper section of bag thoroughly. Use one hand to aid washing process. Wet
surface of insulation in lower section of bag and any exposed ends of asbestos
insulation remaining on pipe.
4. Prior to removing bag from the pipe, wash the top section of the bag and tools
thoroughly. Insert nozzle of HEPA filtered vacuum into bag through the elasticized
valve and evacuate air from bag. Seal the closure strip, remove the vacuum nozzle
and straps, and remove the bag. Re-install and seal in new location before
reopening closure.
5. If bag is to be moved along the same pipe, loosen securing straps, move bag, reseal to pipe using double-pull zipper to pass hangers. Repeat insulation removal
operation.
6. If during use the glove bag is ripped, cut or opened in any way, cease work and
repair opening before continuing work. All spilled material must be cleaned up and
removed with a HEPA vacuum or wet cleaning.
7. To remove bag after completion of insulation removal, thoroughly wash top section

of bag and tools and seal internal zip-lock closure. Place tools in one glove, pull
hand out inverted, twist to create a separate pouch, tape inside-out glove at two
separate locations 1" apart to seal pouch. Remove inside-out glove and tools by
cutting between the tape seals.
Place glove pouch and tools into the next clean glove bag to be used. Alternately,
place the tool pouch into water bucket, open pouch underwater and clean tools,
then allow to dry.
Prior to disposal of bag, evacuate the bag with a HEPA vacuum. Pull a 0.15 mm (6
mil) polyethylene bag over glove bag before removing from pipe. Remove securing
straps. Unfasten zipper. Seal glove bag and seal 0.15 mm (6 mil) polyethylene bag.
After removal of bag ensure pipe is clean of all residue. If necessary, after removal
of each section of asbestos, vacuum all surfaces of pipe, using HEPA filtered
vacuum equipment, or wipe with wet cloth.
Seal all surfaces of freshly-exposed pipe with encapsulating sealer to tack-down
any residual dust. Cover exposed ends of any remaining asbestos insulation with
lagging cloth or tape.
Before leaving work area, a worker shall decontaminate shoes and protective
clothing by using HEPA vacuum or damp wiping. When protective clothing is to be
disposed of, it shall be decontaminated as above and placed in labelled disposal
bags. Workers shall vacuum all exposed skin, suit, respirator and hair (after
removing hood) and proceed to nearest washroom to wash hands and face.
Waste Transport and Disposal
1. Place waste containers in storage area for holding asbestos waste. Containers shall
be labelled and assigned exclusively for asbestos waste.
2. Prepare waste for disposal in compliance with provincial regulations. The Property
Manager will arrange for disposal.
Asbestos Work Procedures
Emergency Asbestos Work Procedures
Emergency asbestos procedures shall be implemented when required in order to protect those
undertaking the work, as well as to protect all others from, or limit exposure to, airborne asbestos.
Procedures indicated shall be followed as closely as possible, in the event of an emergency
situation.
Procedures for asbestos work, required as an immediate response to floods, pipe breaks, ceiling
collapses, or other emergencies that affect asbestos materials, are as follows:
1.
2.
3.
4.
Clear area of all occupants.
Construct enclosure around area if time permits.
Shut down ventilation system serving area.
Worker performing repair shall wear protective respirator and disposable suit. If normal
work clothes are worn they must be disposed of if visibly contaminated.
5. Use drop sheet under work, if possible, to minimize clean-up.
6. Perform emergency repair with minimum disturbance of asbestos.
7. Obtain asbestos equipment and perform clean-up of visible material. Use HEPA filtered
vacuum or wet cleaning. Dispose of all cleaning supplies as contaminated waste.
8. The worker should wipe off or vacuum disposable clothing and footwear. Proceed to
washroom to wash face and hands.
9. Notify the Property Manager regarding the asbestos disturbance, before allowing
unprotected persons to enter the area. The Property Manager will contact the Regional
Asbestos Coordinator to determine if additional precautionary measures are to be
implemented. The Regional Asbestos Coordinator will arrange for removal, clean-up or
repair of the asbestos material.
10. The Regional Asbestos Coordinator shall investigate the extent of asbestos disturbance,
will determine additional actions to be undertaken and will determine if a hazard
investigation under the Canada Occupational Safety and Health Regulation is
appropriate.
Bulk Sample Collection Procedures
1. Sample the material when the area is not in use. Only those persons needed for
sampling should be present in the immediate area.
2. Spray the material with a light mist of water to prevent fibre release during sampling. Do
not disturb the material any more than necessary.
3. Materials of different appearance should be sampled separately. Mechanical insulation
must be sampled separately on all systems, tanks, vessels, etc. Sample both the straight
sections of pre-formed insulation and the insulating cement typically present at elbows,
fittings, etc. (unless visually identified as fibreglass).
4. Collect the sample by penetrating the entire depth of the material, as the insulation may
have been applied in more than one layer or covered with paint or other protective
coating.
5. The use of a respirator is recommended for all sampling. Depending on the condition of
the material, significant amounts of airborne fibres can be generated during sampling.
6. If pieces of material break off during sampling, the contaminated area must be cleaned
up with a HEPA vacuum cleaner or by wet cleaning. Any debris generated must be
placed in plastic bags, labelled, sealed and disposed of as asbestos waste.
7. Place samples in labelled plastic bags with a zip-lock closure or in sealed plastic vials.
Samples shall be identified with the following information:
 Sample Number;
 Building;
 Room Number;
 Date of Sampling;
 Name of Sampler;
 Source of sample, e.g., Cold Water Pipe, Cold Water Fitting, etc.
8. Temporarily seal any openings created to collect the sample, (for example, with tape,
paint or metal foil tape wrapped completely around the pipe). Advise the Property
Manager or Regional Asbestos Coordinator.
9. Analysis must be performed by the Health Canada Laboratory or by a laboratory
accredited by the National Voluntary Laboratory Accreditation Program (NVLAP). Contact
the Regional Asbestos Coordinator for a list of acceptable laboratories.
Respirator Fitting, Inspection, Cleaning and Disinfecting
Notes for Air Purifying Half-Facepiece Respirators
WARNING: This respirator does not supply oxygen. It must not be used in or for: oxygen deficient
atmospheres (less than 19.5%); poorly ventilated areas or enclosed spaces such as tanks or
small rooms; abrasive blasting or firefighting; or for protection against contaminants excluded or
not covered by the applicable Approval Label.
Respirators must be approved for protection against asbestos. Check for NIOSH certification.
1.
Respirator Fitting
Persons required to wear respirators must first pass a qualitative fit-test administered
according to the current version of CSA standard Z-94.4. The fit-test should be repeated
yearly.
2.
Inspection Items Prior to Each Use
1. Examine facepiece for:
 dirt;
 cracks, tears or holes;
 distortion and inflexibility;
 cracks or breaks in filter holders, worn threads and missing gaskets.
2. Examine head straps for:
 breaks or tears;
 loss of elasticity;
 broken or malfunctioning buckles and attachments.
3. Examine valves for:
 detergent residue, dust or other material on valves or valve seats;
 cracks, tears or distortion in the valve material;
 missing or defective valves or valve covers.
4. Examine filter for:
 proper filter for protection against asbestos (High Efficiency Particulate);
 incorrect installation, loose connections, missing or worn gaskets or cross
threading;
 cracks or dents in filter housing.
5. Leak-checks:
Perform the following tests on each donning:


3.
negative pressure test: cover inlets to filters, breathe in and hold breath;
respirator should be drawn to face for minimum of ten seconds (if not,
check exhalation valve and fit);
positive pressure test: cover exhalation valve cover and puff out slightly and
hold breath; respirator should slightly pressurize and still hold seal (if not,
check inhalation valves and fit).
Respirator Cleaning and Disinfecting
1. Remove filters and disassemble facepiece. Discard or repair defective parts.
2. Wash components in warm water (50°C - 60°C) with mild detergent, using a brush.
Cleaning and disinfectant solutions are available from respirator manufacturers.
3. Thoroughly rinse components in clean, warm water.
4. Air dry or hand dry components with a clean, lint-free cloth.
5. Reassemble respirator and test to ensure that all components are working properly
(see above). Be careful to check that valves are not lost in the cleaning.
4.
Filter Cartridge Handling and Replacement
1. Filters can be reused until an increase in breathing resistance is noted. Under
typical Type 2 conditions, filter cartridges should last a minimum of 24 hours. Inlet
side of filter cartridge to be reused shall be sealed on the inlet side with tape for
storage.
2. When no longer usable, filter cartridges will be sealed on the inlet side with tape,
and disposed of as contaminated waste.
