Ais forAsbestos
Asbestos refers to a group of silicate rocks that have the interesting property of forming long, thin fibers. Asbestos was cheap, strong, had great insulating qualities and was widely used as a building material, with its use peaking in the 1970s.
Asbestos can cause lung cancer, mesothelioma and other issues if it is inhaled, and because of this its use is currently banned in many countries.
