F-gasesare powerful greenhouse gases that trap heat in the atmosphere and contribute to global warming. Ozone-depleting substances (ODS) are gases which damage the ozone layer in the upper atmosphere. They are being phased out, but can be found in older equipment. There are also a few exceptions for certain uses. Common uses for ODS and F-gasesinclude refrigeration and air-conditioning equipment, aerosols, solvents, foam blowing agents, firefighting fluids and high voltage switchgear.
