Asbestos is a naturally occurring mineral that was commonly used in building materials until the 1990s. It was valued for its strength, durability, and fire resistance, and was often found in insulation, roofing materials, floor tiles, and other products. However, it was later discovered that asbestos fibers can become airborne when materials are damaged or disturbed, and can cause serious health problems when inhaled.

Exposure to asbestos can cause lung cancer, mesothelioma, and other respiratory illnesses, often years or even decades after the initial exposure. As such, it is important to identify and manage asbestos-containing materials in order to prevent exposure and ensure the safety of building occupants.
