One group of gases is particularly

One group of gases is particularly likely to damage the ozone layer. These gases are called CFCs, Chloro-Fluoro-Carbons.
CFCs are used in some spray cans to force the contents out of the can.
They are also used in refrigerators, air conditioning systems and some fire extinguishers. They are used because they are not poisonous and do not catch fire.
Most countries have now stopped using new CFCs that can be released into the atmosphere, but many scientists believe we must stop using old ones as well.
