Asbestos is a type of naturally occurring mineral that was once used extensively in construction and other industries due to its heat-resistant properties. It was used in a variety of materials, such as insulation, cement, and flooring tiles. However, exposure to asbestos fibers can be extremely dangerous, leading to serious health issues such as lung cancer, mesothelioma, and asbestosis. The use of asbestos has been prohibited since 1999 in the UK, but many buildings still contain asbestos-containing materials (ACMs).
