Asbestos is the generic name for a variety of fibrous minerals found naturally in rock formations around the world. Because asbestos fibres are strong, durable and non-combustible, they were widely used by industry, mainly in construction and friction materials. Inhalation of airborne asbestos fibres in significant quantities poses health risks and can cause asbestosis (a scarring of the lungs which makes breathing difficult), mesothelioma (a rare cancer of the lining of the chest or abdominal cavity) or lung cancer.
In Ontario, a material is defined as containing asbestos if the material has a minimum asbestos content of 0.5%. Asbestos-Containing Materials (ACMs) can be divided into two categories: friable and non-friable material. A friable material is a material that can be crumbled, powdered, or pulverized by hand pressure and can readily releases fibres when disturbed. Common application of friable asbestos are sprayed or trowelled surfacing materials (sprayed fireproofing, textured coatings and plaster finishes) as well as mechanical and thermal insulations.
Non-friable materials are materials that will generally release fibres only when cut or shaped. Common non-friable ACMs include vinyl floor products, drywall joint compounds, asbestos textile products and asbestos cement products (transite). Some of these products may become friable with time or when disturbed.
         Regulatory Requirements 
The disturbance of asbestos-containing materials on construction projects is controlled by the Ontario Occupational Health & Safety Act, R.S.O. 1990, Regulation 278/05, Designated Substance – Asbestos on Construction Projects and in Buildings and Repair Operations. This Regulation classifies all asbestos disturbances as Minimum (Type 1), Intermediate (Type 2), or Maximum (Type 3), each of which has defined precautionary measures. All asbestos materials are subject to specific handling and disposal precautions, and must be removed before partial or full demolition. The Ministry of Labour must be notified of any project involving removal of more than a minor amount of friable asbestos material. All ACMs referenced in this report were observed to be in good condition unless otherwise specified.
Disposal of asbestos waste is controlled by the Ontario Environmental Protection Act, R.R.O., 1990, Regulation 347 as amended by O.Reg. 461/05, General – Waste Management. This regulation requires that asbestos waste be sealed in double containers resistant to puncture and tears, and appropriately labelled. The waste must be disposed at a licensed waste disposal site. Proper notification must be issued to the site representative prior to transportation of waste. The transport of the waste to the disposal site is controlled by the federal Transportation of Dangerous Goods Act, 1992.
