Did you know?

A grayish mineral that separates readily into long, flexible fibers, asbestos was used in the past to make brake linings, insulation, roofing shingles, floor and ceiling tiles, cement pipes, and other building materials. Asbestos fabrics were used for safety apparel and theater curtains. In the 1970s, it was found that prolonged inhalation of the tiny asbestos fibers can cause asbestosis, lung cancer, and other serious lung diseases. In 1989, the US Government instituted a gradual ban on the manufacture, use, and export of most products made with asbestos.
