Asbestos is a material that was commonly used in building construction between the 1950s and 1980s. It was popular because it offered excellent heat resistance and had great durability. However, it was later discovered that asbestos was hazardous and could cause various respiratory illnesses, including lung cancer, asbestosis, and mesothelioma.

Due to this health risk, the UK government banned the use and importation of all forms of asbestos products in 1999. However, many buildings in Kings Nympton and other parts of the UK still contain asbestos, which can pose a risk of contamination if not removed correctly.
