Asbestos is a naturally occurring mineral that was used in insulation, construction materials, and other products due to its heat resistance and durability. However, asbestos fibers can be extremely hazardous when inhaled and can lead to serious health problems, including lung cancer and mesothelioma.

While asbestos use has been heavily regulated and restricted in recent years, it is still present in many buildings and materials, particularly those constructed before the 1980s.
