Asbestos is a naturally occurring fibrous mineral that was widely used in many industries due to its heat-resistant and insulating properties. It was often added to building materials such as insulation, flooring, roofing, and pipes. When these materials become damaged or disturbed, it can release asbestos fibers into the air. When inhaled, these fibers can cause serious lung diseases, including mesothelioma, lung cancer, and asbestosis. Asbestos-related diseases often have a long latency period, which means symptoms may not appear for many years after exposure.
