Asbestos is a naturally occurring mineral fiber used as a building material before the 1980s. The purpose of adding this fiber in the building material was to enhance the strength and make it fire resistant. Commonly, rocks and soil contain this mineral fiber. Steam pipes, boilers, ceiling panels, floor tiles, and other cement products contained this mineral fiber in the early years. The primary aim was to strengthen the material and use it as a fire retardant.
It was in the 1970s; the United States has issued warnings to banning the use of Asbestos. Clean Air Act of 1970, the Toxic Substances Control Act of 1976, Asbestos Hazard Emergency Response Act of 1986 and the Asbestos Ban and Phase-out Rule of 1989 are the legislation governing the ban of Asbestos.
