Asbestos is a naturally occurring mineral that was widely used in building construction due to its heat-resistant properties. It was commonly used for insulation, tiles, roofs, plumbing, and other building materials. However, it was later discovered that asbestos exposure is a significant health hazard, causing severe health problems such as lung cancer, mesothelioma, and asbestosis.

In the UK, the use of asbestos was banned in 1999. However, asbestos is still present in many buildings constructed before 2000, making it a serious concern for homeowners and business owners alike.
