LPG - Liquid propane gas
or other Hydrocarbon derivatives...
Soft CFC's, they added hydrogen to the CFC's previously used that were called hard CFC's. By doing this it won't allow the CFC's to travel up to the stratosphere, where it breaks down the ozone. With the added hydrogen will stop it in the troposphere and combine to form compounds such as CO2 + HCl (or HF), therefore not harmful to the ozone.
Examples CH2Cl (HCFC-22) or CHCl2-CF2 (HCFC-123)

CFC gas is used for cooling refrigerator.

No. CFC's are a man made gas.
Ozone is depleting. It is depleting due to the CFC's used by the humans.
CFC gas
Yes. Tetrafluoroethane is a non-CFC gas. CFCs are chlorfluorocarbons which contain both chlorine and fluorine. Tetrafluoroethane does not contain chlorine.
CFC's
Most aerosol cans now use non-CFC propellants and are generally much kinder to the environment. Therefore they are far less damaging to the ozone-layer. Unfortunately HCFC gas used as a replacement for CFC's is potent greenhouse gas.
CFC or chloroflourocarbon
CFC stands for chlorofluorocarbon, which is a harmful greenhouse gas that depletes the ozone layer. CFC-free inhalers are inhalers that do not contain this harmful gas and are considered more environmentally friendly. These inhalers use different propellants, such as HFA (hydrofluoroalkane), to deliver medication.
