Asbestos is a naturally occurring, fibrous mineral. It is mined in Canada, the Soviet Union and South Africa. There are three common types of asbestos: chrysotile, amosite, and crocidolite. Asbestos possesses substantial resistance to heat, chemical corrosion, and tensile strength and has been used for a variety of residential, commercial and industrial products. Commonly, asbestos is used as an insulation material and for acoustical and decorative purposes.
