Asbestos describes any of a group of minerals that can be fibrous, many of which are metamorphic and are hydrous magnesium silicates. It is used for its resistance to fire or heat; the fibers are often mixed with cement or woven into fabric or mats. The small, buoyant fibers are easily inhaled or swallowed, causing a number of serious diseases including: Asbestosis, a chronic disease of the lungs that makes breathing more and more difficult; cancer; and mesothelioma, a cancer (specific to Asbestos exposure) of the membranes that line the chest and abdomen.
Asbestos is used in brake shoes and gaskets for its heat resistance, and in the past was used on electric oven and hotplate wiring for its electrical insulation at elevated temperature, and in buildings for its flame-retardant and insulating properties, tensile strength, flexibility, and resistance to chemicals. Many uses of Asbestos are banned in multiple countries.
