• Solvent: Used in the rubber, chemical, and drug industries, as well as in the paint industry
• Cleaning agent: Used in dry cleaning and as a degreasing agent in industry
• Fire extinguisher: Used as an occluding and nonoxidizing agent in fire extinguishers
• Fumigant: Used to kill insects in grain
• Refrigerant: Used to produce refrigerants
• Propellant: Used to produce propellants for aerosols
• Medicine: Used as an anthelmintic to treat hookworm and other intestinal parasitic diseases
• Veterinary medicine: Used to treat canines

Restrictions

• Production, sale, and use of carbon tetrachloride has been restricted in many places 
• Consumer and fumigant uses have been discontinued
