Asbestos is a naturally occurring mineral that was widely used in construction and manufacturing until the late 20th century. It was valued for its heat-resistant properties and was commonly used in insulation, roofing, flooring, and other building materials. However, over time it became clear that asbestos was a dangerous substance that could cause serious health problems, including lung cancer and mesothelioma.

As a result, asbestos was banned in the UK in 1999, and it is now illegal to use, import, or sell asbestos or asbestos-containing products. However, many older buildings still contain asbestos, and it is important to ensure that any asbestos-containing materials are handled and disposed of safely.
