Asbestos is a group of naturally occurring silicate minerals that were extensively used in construction and other industries due to their durability, heat and fire resistance, and insulating properties. However, asbestos is also a known carcinogen and can cause serious health problems when inhaled or ingested.

Asbestos was widely used in the UK until it was banned in 1999. However, many older buildings still contain asbestos-containing materials (ACMs) such as pipe insulation, ceiling tiles, and floor coverings. Asbestos is only dangerous when it is disturbed and the fibers become airborne, so it needs to be carefully managed or removed.
