Asbestos is a naturally occurring mineral that has been used in building materials since the early 20th century. It is heat-resistant, durable, and was commonly used in insulation, construction, and fire protection. Unfortunately, it poses serious health risks, especially when the fibers become airborne and are inhaled. Asbestos exposure is linked to lung cancer, mesothelioma, asbestosis, and other respiratory diseases. Asbestos was banned in the UK in 1999, and regulations were put in place to control its disposal.
