Asbestos is a naturally occurring mineral that was used extensively in the construction industry in the past due to its excellent insulation and fire-resistant properties. However, it was later discovered that prolonged exposure to asbestos fibers can lead to serious health problems such as lung cancer, mesothelioma, and asbestosis.

Asbestos was finally banned in the UK in 1999, but many buildings constructed before this date still contain asbestos-containing materials (ACMs) such as insulation, tiles, and cement. It is important to identify and manage these materials to prevent the release of asbestos fibers into the air.
