Historically mined in Libby, Montana, asbestos was a common additive in various construction materials until around 1990. Later identified as a carcinogen, its use in building materials is now banned in Canada.
The danger of asbestos emerges when it becomes airborne, especially during renovations of older properties. Materials that may contain asbestos include:
- Window sealants
- Certain paints
- Exterior wall coatings
- Stucco finishes
- Roofing materials
- Drywall joint fillers or textured ceilings
- Plaster laths
- Insulation solutions for floors or attics
Disrupting Asbestos-Containing Materials (ACM), such as breaking apart drywall joint fillers or attic renovation, can release asbestos fibers into the air. These fibers, once inhaled, lodge in the lungs and are impossible to remove. Incorrect handling and disposal of ACM can contaminate an entire property, posing health hazards to all occupants.
