• The early programs included the elimination of lead in gasoline, the phase-out of chlorofluorocarbons and halons in refrigeration, and the reduction of water pollution from nonpoint sources.

• Chlorofluorocarbons may damage the statospheric ozone layer, but at the moment the evidence for this is uncertain.

• All halon fire extinguishers have been replaced and regular checks for chlorofluorocarbon leakage detection are carried out on relevant departmental equipment.

• All new equipment purchased is free from chlorofluorocarbons.

• Manufacturers are looking at alternative chlorofluorocarbons and other substitute compounds, but ones with suitable properties are difficult to find.

• These will be taken into account in the course of our current appraisal of the possible effects of chlorofluorocarbons.

• It is assumed that all the chlorofluorocarbons used in the manufacture of metered dose inhalers will eventually be emitted to atmosphere.
