Asbestos is a highly hazardous material, which was widely used in construction during the 20th century, due to its abundance, affordability, and fire-resistant properties. However, exposure to asbestos fibres can cause serious and potentially fatal health problems, including lung cancer, pleural mesothelioma, asbestosis, and other respiratory diseases.

Asbestos is commonly found in building materials, such as insulation, cement, pipe fittings, roofing tiles, and floor tiles. When these materials are damaged or disturbed, they release asbestos fibres into the air, which can be inhaled and cause damage to the lungs.
