Dichlorofluoromethane is a colorless heavy gas that is used as a refrigerant, solvent, propellant and heat-exchange fluid. It is also referred to as CFC-21 but has fewer uses than other chlorofluorocarbons. Inhalation of dichlorofluoromethane can cause confusion, drowsiness, and unconsciousness; and direct contact with skin can cause frostbite.
