The Ontario Construction Safety Act in 1973 prohibited the use of sprayed-on asbestos. Following that prohibition, major suppliers of pipe and boiler insulation stopped using asbestos containing materials (ACMs). Asbestos was used in the manufacturing of many other substances until the mid 1980s. Buildings pre-dating 1990 may contain building materials that use asbestos as a component.

The Ministry of Labour identifies Asbestos as a designated substance. Ontario Regulation 278 / 05 made under the Occupational Health and Safety Act presents a course of action to follow for building owners to determine whether ACMs exist in their buildings. Ontario Regulation 278 / 05 also presents a course of action to follow if ACMs are present (e.g. repair, remove or manage in place). Managing the ACM in place requires that the building is surveyed so that the ACMs can be identified, their physical condition determined and the information catalogued (by way of completing an “ACM survey”).
The following are examples of common materials that may potentially contain asbestos:

  • Adhesives, caulking, mastics, and putties;
  • Insulation (e.g. Boiler insulation, pipe insulation, vermiculite, and sprayed on fire proofing);
  • Ceiling tiles;
  • Cement products (e.g. Siding and ceiling tiles);
  • Plaster;
  • Roofing shingles, felts, and tars;
  • Drywall compounds and tapes;
  • Various fabrics (e.g. duct vibration dampeners, sweat wraps, and heat shields);
  • Vinyl sheet floor, vinyl floor tiles, and underlying mastics; and,
  • Wall boards

JFM services include the sampling and analysis of materials suspected to contain asbestos, and the preparation of inventories of the material for the purposes of their subsequent management under the regulation.

JFM also offers independent inspection services of the work of any third party contractor engaged to remove ACMs. These services include the monitoring of air quality outside the removal area, to evidence and document for liability limitation purposes that acceptably safe air quality conditions existed elsewhere within the affected building during abatement operations.

Acceptable levels of asbestos fibres in air are dictated by the Occupational Health & Safety Regulations in Ontario, and establishing an independent record of air quality outside an asbestos work enclosure is fundamental to limiting a client’s long tail liability that might otherwise potentially become associated with an asbestos removal operation. Although a removal contractor may elect to conduct air quality measurements themselves for their own purposes, an independent record obtained on behalf of the property owner can be invaluable because of the contractor’s inherent conflict of interest in policing their own operations.

Once an abatement project reaches its final stages, JFM will inspect and further document the completeness and adequacy of the contractor’s work. In conjunction with the independently obtained air quality record, JFM is then in a position to report back to the client that any substances in question have been properly removed in accordance with the terms of the removal contract and the applicable regulatory requirements, thereby satisfying the due diligence obligations of the client.
