How you can help to protect the ozone layer? While the vast majority of ozone depleting substances usage is either industrial or commercial, individuals can help in the following ways: Buy air-conditioning equipment, refrigeration appliances that do not use CFC as refrigerant. Conduct regular inspection and maintenance of air-conditioning and refrigeration appliances to prevent and minimize refrigerant leakage. For existing air-conditioning and refrigeration appliances that operate on CFCs, the refrigerant should be recovered or recycled whenever an overhaul of equipment is to be carried out. Replacing or retrofitting such equipment to operate on non-CFC refrigerant should also be considered. When motor vehicle air-conditioners need servicing, make sure that the CFC refrigerants are properly recovered and recycled instead of being vented to the atmosphere. When using CFC-113 as solvent or cleaning agent, make sure that the chemical is properly handled so that evaporation losses are minimized and the waste solution is recycled as far as possible. Alternative technologies such as aqueous cleaning should also be considered.
