CFCs have been used in refrigerant as refrigerator and the insulation materials for many years. But it is now
known that these compounds which once seemed so ideal for use as cleaning agents and in refrigeration
systems, destroy the earth’s ozone layer as a result, an international body decided on a total worldwide ban of
harmful CFCs by the end of 1995.
