Asbestos fibers can be released into the air and inhaled, posing a health risk. These invisible fibers are 400 to 2,000 times smaller than a human hair and can cause serious health problems after several years, including asbestosis, lung cancer and mesothelioma.
Materials containing asbestos can have health consequences if their condition deteriorates or if work is carried out (maintenance, repair, renovation, demolition, etc.), which could emit dust from these materials. So, as long as they are in good condition and no such work is planned, materials containing asbestos do not pose a significant health risk, according to Health Canada’s website.
