4 — ASBESTOS MANAGEMENT PROGRAM
4.1 Inventory of Asbestos-Containing Materials
The University has surveyed University facilities to determine the type, location, and content of asbestos-containing materials.
The resulting inventory of asbestos-containing materials is maintained by Facilities Management and is updated as new information becomes available.
You can obtain copies of the reports by contacting Facilities Management at fixit@mta.ca.
If Facilities Management suspects that materials not in the inventory contain asbestos, that department has those materials tested by an appropriate laboratory.
4.2 Demolition, Alteration, Renovation and Maintenance Work
Whenever such work is being done, Facilities Management reviews its inventory of asbestos-containing materials to determine if the work will involve such materials.
If the work involves such materials, normally the work identified in Appendix A attached hereto is done by Facilities Management staff as described in that Appendix. These are typically Class 1 Asbestos operations as defined in the Code.
Normally, other work involving such materials is done by contractors qualified and experienced with asbestos operations, typically Class 2 and 3 Asbestos operations as defined in the Code.
In the event a Class 2 or a Class 3 operation is done, before work is commenced an officer at the nearest office of the Occupational Health and Safety Commission is supplied either by the contractor or the University with the information listed in Section 9 of the Code.
All such work is done in accordance with the Code.
Asbestos-containing materials are removed whenever it is reasonable to do so as part of an alteration and renovation project.
4.3 Damaged or Deteriorated Asbestos-Containing Materials
Any damaged or deteriorated asbestos-containing materials is cleaned up and removed in accordance with the Code.
Where it is readily apparent that deteriorated asbestos-containing materials will continue to deteriorate, the materials are repaired, sealed, removed or permanently enclosed.
5 — ASBESTOS TRAINING PROGRAM
5.1 Facilities Management Staff
Facilities Management staff have been trained to ensure that any work that they do that might involve asbestos-containing materials will be done with due regard for their safety and for the safety of others. New members of staff will receive such training as soon as possible after their employment. A refresher training course will be given to these staff members once every three years.
5.2 Other Staff
Whenever it is determined that an employee may disturb asbestos-containing materials, that employee will be trained to ensure that employee’s safety and the safety of others. Refresher training courses will be given to such employees once every three years.
5.3 Contents of Training
Training includes the items listed in sections 4.3 and 8 of the Code as are applicable in the circumstances.
6 — WORK OF CONTRACTORS ON UNIVERSITY FACILITIES
6.1 Purchase Order Requisitions
Purchase order requisitions that will involve contractors working on University facilities will indicate whether the work could disturb materials in those facilities and, if so, what those materials are.
6.2 Issuing the Purchase Order
Whenever it receives a copy of a purchase order requisition pursuant to section 6.1 above, Facilities Management without delay will a) determine whether or not the materials that will be disturbed contain asbestos and b) advise Purchasing of the determination.
6.3 Purchase Orders
In any case where a determination is required under section 6.2 above, a purchase order will not be issued by Purchasing until the determination is made by Facilities Management.
If a purchase order is issued for work that will disturb asbestos-containing materials, the purchase order will require the contractor to contact Facilities Management before doing the work so that Facilities Management can ensure that the work is done in accordance with this Policy.
Appendix A — Protocols for typical asbestos-related work
Type of Asbestos-Related Work
This protocol was developed to assist with:
- cleaning up plaster, drywall and stucco debris originating from minor damage in various Mount Allison University (MtA) campus buildings;
- minor work to plaster and drywall walls and ceilings to install pictures, shelves, hangers and electrical boxes;
- minor repairs to vinyl floor tiles;
- cleaning and buffing vinyl floor tiles; and
- removal of fluorescent lamp ballasts with asbestos containing wire wrapping.
This protocol was NOT developed to serve as a guide for other types of asbestos removal or for larger asbestos removal operations.
Equipment required
The following equipment is available and must be used when dealing with asbestos in the above situations:
- HEPA vacuum
- Damp rags
- Misting bottle with soapy water
- Barricade tape
- Half-faced respirator with P-100 cartridge
- Disposable suit
- Asbestos waste bags
- Duct tape
Procedure
Cleaning up plaster, drywall and stucco debris originating from minor damage in various MtA campus buildings.
- Use barricade tape to restrict access to area of damage. Tracking dust and debris about via foot traffic is the greatest concern. Overall, drywall dust, stucco and plaster are not inherently dusty and exposure to students and university staff resulting from the actual damage is expected to be negligible.
- Don respirators and, if contact with debris is likely, disposable suits over street clothes.
- Mist area of damage and fallen debris with soapy water.
- Place larger materials directly into waste bag trying to avoid dust generation as possible.
- Use HEPA vacuum to remove remaining dust
- Repair damaged area as required. Cover floor with polyethylene sheeting as needed to contain expected dust generation. Additional removal of asbestos containing materials should be avoided but removal of some materials will be required to facilitate repairs.
- Use 6-mil or rip-proof tarp to cover damaged area if proper repair will require additional asbestos removal that will be contracted out. Otherwise, repair area as required by crackfilling or covering with rigid materials such as plywood or sheetrock.
- Reclean areas as per items 3-5 above.
- Fold polyethylene floor covering toward centre and dispose of as asbestos waste together with disposable suits and other debris. Place waste bag inside second bag and seal.
Minor work to plaster and drywall walls and ceilings to install pictures, shelves, hangers and electrical boxes
- Use barricade tape to restrict access to work area. Tracking dust and debris about via foot traffic is the greatest concern. Overall, drywall dust, stucco and plaster are not inherently dusty and exposure to students and university staff resulting from the actual work is expected to be negligible.
- Don respirators and, if contact with debris is likely, disposable suits over street clothes.
- Mist work area with soapy water.
- Cover area beneath work area (1 metre radius) with polyethylene sheeting.
- Either a) use HEPA vacuum nozzle positioned near tool work area to collect dust as it is generated or b) allow debris to fall onto polyethylene sheeting and immediately remove by HEPA vacuuming. Use of hand tools is preferable over power tools where practical. Low speed power tools are preferred over high-speed tools.
- Place larger materials directly into waste bag trying to avoid dust generation as possible.
- Use HEPA vacuum to remove remaining dust.
- Fold polyethylene floor covering toward centre and dispose of as asbestos waste together with disposable suits and other debris. Place waste bag inside second bag and seal.
Minor repairs to vinyl floor tiles
- Vinyl floor tiles are not inherently dusty and they are not considered to be friable.
- Use barricade tape to restrict access to work area. Don respirators.
- Tiles to be removed (maximum of two in any area) should be pried free from the adhesive using a suitable pry tool. Try to avoid breakage as possible. Tiles should be placed directly into asbestos waste bags
- Adhesive can be removed if needed by a) heating (do not burn) followed by scraping or b) by soaking is suitable solvent followed by scraping. Scraping of dry adhesive is discouraged. Residue should be placed immediately in asbestos waste bags.
- Area should then be HEPA vacuumed and allowed to dry if a solvent was used. Tile replacement does not require asbestos control measures.
Cleaning and buffing vinyl floor tiles
- Buffing of vinyl floor tiles containing asbestos fibres will generate a small asbestos aerosol if the buffing is allowed to continue into the vinyl tile surface.
- Efforts to avoid buffing beyond the wax layer will reduce asbestos concerns to negligible. Use of any wet process integral to the buffing will further reduce asbestos concerns.
Removal of fluorescent lamp ballasts with asbestos containing wire wrapping
- Ballasts containing asbestos wrapped wires require removal upon failure. The ballasts are not repaired, only removed and replaced.
- Use barricade tape to restrict access to work area.
- Don respirators and, if contact with debris is likely, disposable suits over street clothes.
- Mist work area with soapy water ONLY after de-energising the power supply to the ballast.
- Cover area beneath work area (1 metre radius) with polyethylene sheeting.
- Carefully remove ballast including all wiring and place directly into asbestos waste bag.
- HEPA vacuum and large bits of asbestos debris that are discovered after removal of the ballast.
- Damp wipe metal surfaces within fluorescent tube holding frame using spray bottle and soapy water.
- Fold polyethylene floor covering toward centre and dispose of as asbestos waste together with disposable suits and other debris. Place waste bag inside second bag and seal.
