This article presents information on the hazards of crystalline silica. The disease contracted because of this substance can be progressive and disabling and can lead to death. According to the Occupational Safety and Health Administration (OSHA), 1,400 people died of silicosis from 1990 through 1996. Exposure to crystalline silica also may increase the risk of developing tuberculosis and other nonmalignant respiratory diseases and contribute to renal and autoimmune respiratory diseases. In addition, the International Agency for Research on Cancer has designated crystalline silica as a known human carcinogen. In spite of the dangers, OSHA reports that more than two million workers are regularly exposed to crystalline silica dust.
