Asbestos is a naturally occurring mineral that was commonly used in construction materials such as insulation, flooring, roofing, and ceiling tiles. It was also used in industrial settings for its heat-resistant properties. However, it has been banned in the UK since 1999 due to its hazardous health effects.

Asbestos fibers are microscopic and can be easily inhaled. Over time, long-term exposure can lead to serious respiratory diseases such as asbestosis, lung cancer, and mesothelioma.
