Asbestos is a naturally occurring mineral that was once commonly used in construction materials. It is highly durable and fire-resistant, making it ideal for use in insulation, roofing, and flooring. However, asbestos is also highly hazardous to human health. When asbestos-containing materials are disturbed or damaged, they release microscopic fibers that can be inhaled into the lungs. Over time, these fibers can cause serious health problems, including lung cancer, mesothelioma, and asbestosis.
