Asbestos is a naturally occurring mineral fiber that was widely used in construction materials until the 1980s when it was discovered to cause serious health problems. When asbestos-containing materials (ACMs) are disturbed, such as during renovation or demolition works, asbestos fibers can be released into the air and inhaled by humans. Asbestos exposure can cause a range of serious lung diseases, including asbestosis, lung cancer, and mesothelioma. There is no safe level of exposure to asbestos, and even short-term exposure can have long-lasting and deadly health consequences.
