Asbestos is a naturally occurring mineral that was widely used in the construction industry in the UK until it was banned in 1999. It was used in a variety of building materials, including insulation, roofing, and fireproofing materials. Although asbestos is no longer used in construction, many older buildings still contain asbestos-containing materials (ACMs).

Asbestos is a dangerous substance that can cause serious health problems if it is not properly handled and removed. Asbestos fibres are easily airborne and can be inhaled, causing damage to the lungs and respiratory system. Asbestos exposure has been linked to lung cancer, mesothelioma, and other respiratory diseases.
