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.
