Asbestos Containing Building Materials 

Asbestos was used in building materials in Canada up until the 1980s, some products manufactured today still use asbestos. Asbestos containing material (ACM) can be found throughout the home and work place, below is a non exhaustive list of potential ACM.

Friable and Non-Friable

ACM can be further divided between Friable ACM and Non-friable ACM. 


  • Friable ACM is easily crumbled or pulverized with the force exerted by ones fingers.

    Examples include plasters, joint compounds and some insulations. 


  • Non-friable ACM is held together by some type of binding agent. 

    Examples include floor tiles, ceiling tiles and adhesives. 


Friability is important as it in part determines the level of risk posed to personnel who are working with or around the materials.
