Asbestos is a mineral substance that was widely used in building materials due to its strength, durability, and resistance to heat and fire. However, the mineral has proven to be a significant health hazard, and its use has been banned in the UK since 1999.

Asbestos fibres can be released into the air when building materials containing asbestos are damaged or disturbed, such as during renovations or demolition. Breathing in these fibres can lead to lung cancer, mesothelioma, and other respiratory diseases.

According to the Health and Safety Executive (HSE) guide, asbestos can be found in various building materials such as insulation, ceiling tiles, pipes, and roofing materials commonly found in buildings constructed before the year 2000.
