Asbestos is a heat resistant and corrosion resistant fibrous mineral used for fireproofing and insulation. This mineral is naturally occurring and was once heavily used in building materials and automotive parts. For decades, asbestos was used without regard in several major industries and no precautions were taken to limit exposure. Asbestos is now a known carcinogen which can cause disability or death to exposed humans. Up until the 1970s, not much was known about the risks of asbestos and it still took many years for industry regulations to come about limiting the Exposure of asbestos to workers. The use of asbestos is now highly regulated by OSHA and the EPA but many people were exposed before the problem was controlled.
