Asbestos is a naturally occurring mineral that was commonly used in construction materials before its harmful properties were discovered. Exposure to asbestos can cause serious health problems, including lung cancer, mesothelioma, and asbestosis. It is estimated that up to 5,000 people die each year in the UK due to asbestos-related diseases. Asbestos can be found in a wide range of products, including insulation, ceiling tiles, flooring, and roofing.
