| Silicosis is a disabling, nonreversible and sometimes fatal lung disease caused by overexposure to respirable crystalline silica. Silica exposure remains a serious threat to nearly two million US workers. The National Institute of Occupational Safety and Health (NIOSH) reports that each year more than 250 die from silicosis and hundreds more are disabled. There is no cure for the disease, but it is 100 percent preventable if employers, workers, and health professionals work together to reduce exposures. [More...]
