Asbestos is a natural mineral that was commonly used in building materials until its negative health effects were discovered. Asbestos can be found in a variety of building products, including insulation, floor tiles, roofing materials, cement, and more.

Although asbestos-containing materials are not harmful unless disturbed, once they are broken or deteriorate, they can release airborne fibers that are hazardous to humans. Prolonged exposure to asbestos fibers can cause a number of serious health conditions, such as asbestosis and mesothelioma.
