Asbestos is a natural mineral fiber that was commonly used in building materials from the 1950s to the 1990s. It was used in various construction materials, including insulation, flooring, roofing, and piping, due to its durability, heat resistance, and insulation properties. However, asbestos has been found to be a hazardous substance that can cause serious health problems, including mesothelioma, lung cancer, and asbestosis.

Asbestos is dangerous when it becomes airborne and is inhaled, so it is crucial to handle asbestos-containing materials (ACMs) with care. ACMs can become airborne during renovation or demolition of buildings that contain asbestos or when they are improperly handled or disposed of. Therefore, it is necessary to follow strict guidelines for asbestos removal, disposal, and recycling.
