Asbestos is a naturally occurring mineral that was widely used in construction and manufacturing in the 20th century. It was valued for its fire-resistant, durable, and insulating properties. However, it was later discovered that asbestos fibers can cause serious health problems when inhaled. These can include lung cancer, mesothelioma, asbestosis, and other respiratory diseases.

Asbestos is now banned in many countries, including the UK, but the legacy of its use remains. Asbestos-containing materials (ACMs) can still be found in many buildings, especially those built before the 1990s. These materials can release hazardous asbestos fibers when disturbed or damaged. Therefore, it is crucial to identify, manage, and remove asbestos safely and legally.
