Tetrachloroethylene is a colorless, volatile, nonflammable, liquid, chlorinated hydrocarbon with an ether-like odor that may emit toxic fumes of phosgene when exposed to sunlight or flames. Tetrachloroethylene is mainly used as a cleaning solvent in dry cleaning and textile processing and in the manufacture of fluorocarbons. Exposure to this substance irritates the upper respiratory tract and eyes and causes neurological effects as well as kidney and liver damage. Tetrachloroethylene is reasonably anticipated to be a human carcinogen and may be linked to an increased risk of developing skin, colon, lung, esophageal, and urogenital tract cancer as well as lymphosarcoma and leukemia.
