Carbon Tetrachloride was widely used in the early 20th century as a dry cleaning solvent, as a refrigerant, and in fire extinguishers. However, once it became apparent that Carbon Tetrachloride exposure had severe adverse health effects, safer alternatives were found for these applications, and its use in these roles declined from about 1940 onward.
Carbon Tetrachloride persisted as a pesticide to kill insects in stored grain, but in 1970, it was banned in consumer products in the United States. Prior to the Montreal Protocol, large quantities of Carbon Tetrachloride were used to produce the freon refrigerants R-11 and R-12. However, these refrigerants are now believed to play a role in ozone depletion and have been phased out of use, though it is still used to manufacture less destructive refrigerants.
Carbon Tetrachloride should be disposed of as a hazardous waste. It can be taken to any Household Hazardous Waste collection facility or event; see collection information below.
