Long term occupational exposure to the dust can result in lung cancer. Asbestos is resistant to fire and most solvents. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. It is used as a heat resistant material, in cement, furnace bricks, and brake linings."}]
