An
ozone-depleting substance (ODS) is a chemical substance, usually
consisting of some combination of chlorine, fluorine, or bromine plus
carbon, such as chlorofluorocarbons and hydrochlorofluorocarbons that has
been shown to destroy stratospheric ozone. These substances are commonly
found in aerosol products, foams, and fire extinguishers, and are used as
refrigerants and in air-conditioning and cooling equipment.
