Asbestos is a naturally occurring mineral that was widely used in construction materials before its dangers were discovered. The mineral has been linked to a range of health complications, such as mesothelioma, lung cancer, and fibrosis. These health hazards have led to the banning of asbestos in many countries, including the UK. However, many buildings constructed before the ban still contain asbestos, and this poses a significant risk to occupants.

Asbestos is not dangerous when it is intact and undisturbed. However, the fibers can become airborne and pose a risk when the material is damaged or disturbed. Common construction materials that contain asbestos include insulation, flooring, roofing, and piping.
