Asbestos is a naturally occurring, fibrous mineral that was extensively used in the construction industry until the mid-1980s. While the use of asbestos has been banned in many countries, buildings constructed before the ban may still contain asbestos-containing materials.

Asbestos poses a serious health hazard, particularly when asbestos fibres are released into the air and inhaled. Exposure to asbestos can cause a range of serious illnesses, including lung cancer, mesothelioma, and asbestosis.
