Asbestos refers to several types of fibrous minerals derived from certain rock formations. With mechanical and flame retardant properties, asbestos fibers have been widely used in building materials for decades. Overall, the main materials likely to contain asbestos (MLCA) that can be identified in a building are rigid panels made of asbestos cement, cementitious materials (plaster on the ceilings and on the walls), acoustic tiles (ceiling), thermal insulation (pipe overlap), spray material (flocking) and commercial vinyl tile (flooring). Asbestos can be dangerous to the health of the occupants as the fibers are present or released into the air and are inhaled.
According to the law adopted on 24 April 1980 on hazardous materials, the use of asbestos is prohibited as a component in most consumer goods since it is considered dangerous for health. Thus, for buildings built before 1980, the probability of finding MSCA is greater. CNESST regulates the use of asbestos in the workplace.
Environnement PH Inc. offers services in the characterization of materials containing asbestos (MCA). This sampling work will allow for laboratory tests that will establish the asbestos concentration and methodology for asbestos removal work, if applicable. The handling of MCA during renovation or demolition work is governed by section 3.23 of the Safety Code for the construction industry and the Regulation concerning occupational health and safety. Characteristics such as the type of asbestos present, the friability and the volume of material produced by renovation or demolition works are to be considered in the safety measures that need be applied.
