Asbestos is a naturally occurring mineral that was commonly used in building materials throughout the 20th century. It was added to cement, insulation, and other materials to provide strength and heat resistance. However, the health hazards associated with asbestos were not fully understood until later on.

When asbestos is disturbed, it releases tiny fibers into the air that can be breathed in. These fibers can cause serious health problems, including lung cancer, mesothelioma, and asbestosis. Asbestos is therefore a highly dangerous material and should only be handled by trained professionals.
