Asbestos is a naturally occurring silicate mineral that was commonly used in construction materials such as insulation, roofing, and flooring until the 1980s. While asbestos was praised for its heat-resistant properties, it became clear that the material presented a serious health risk to those who came into contact with it.

When asbestos-containing materials are disturbed, such as during renovation or demolition work, microscopic fibers are released into the air. These fibers can be inhaled or ingested and lead to serious health conditions, including lung cancer, mesothelioma, and asbestosis.
