Asbestos is a naturally occurring fibrous mineral that was once widely used in building materials due to its durability, heat resistance, and fire-retardant properties. However, it has been established that asbestos exposure can cause serious health risks, including lung cancer, mesothelioma, and asbestosis.

Asbestos-containing materials (ACMs) are commonly found in older buildings constructed before 2000, such as insulation, ceiling tiles, flooring, roofing, and cement products. If these materials are damaged, broken, or disturbed, they can release tiny asbestos fibers into the air, which can be inhaled and trapped in the lungs.
