!!!Asbest

Asbestos, collective name for various natural fibrous silicate 
minerals. Economically important were in particular chrysotile and 
crocidolite (blue asbestos). On account of their incombustibility, 
excellent insulating properties and high chemical resistance these 
materials were formerly used for asbestos cement, which contained 
approx. 70% asbestos for roofing materials and tubing, approx. 8% in 
the case of flooring materials, roughly 3% for protective clothing and 
roughly 5% for friction linings. Since asbestos causes respiratory 
tract cancer and asbestosis (dust in the lungs), the production and 
marketing of the chief products containing asbestos (fibre cement 
products for building purposes, friction linings and other products in 
which asbestos is poorly bonded) has been prohibited in Austria since 
1990 (Asbestos Regulation). In the last few years, massive 
rehabilitation efforts have been made, in particular where spray 
asbestos had been used for insulation purposes.
