Freon covers a whole host of compounds, and not all members have been seen in the "ozone hole", and not all members have been shown to destroy ozone. One class that has been is CFCs ( C hloro F luoro C arbons), which have shown to be in the ozone hole, photochemically destroy ozone, and persist for a long period of time. Others have been more-recently developed that do not have this behavior.
It is illegal to use #12 due to damage to ozone layer
Freons deplete ozone. They react with ozone to deplete it.
Disposing of a refrigerator containing freon can have harmful environmental impacts because freon is a potent greenhouse gas that contributes to ozone depletion and global warming. Improper disposal can lead to the release of freon into the atmosphere, where it can damage the ozone layer and contribute to climate change. It is important to properly recycle or dispose of refrigerators containing freon to prevent these negative environmental effects.
Freon
Halogen refrigerants are also known as coolant chemicals, which can cause ozone damage. A great example of a common halogen refrigerant would be Freon.
The gas that used to be used in air conditioners and refrigerators, freon, or chlorofluorocarbons (CFCs) would damage the ozone layer. Chlorine would separate from the gas and attack the ozone molecules. These gases are no longer used in air conditioning units. If no further damage occurs the ozone layer will have repaired itself by 2060.
There is many different types of Freon. If the freon that you are trying to use is R-22 then you have to have a EPA certification to handle that freon. This freon is considered ozone depleteing. Now there is freon out there that is not ozone depleting like the freon in cars made after 1993. That is called R-134a which is sold everywhere even in Wal-Mart.
damage to ozone layer is called ozone depletion. It is thinning of ozone layer.
ChloroFluoroCarbon's will damage ozone. Ozone will damage the breathing structures of both plants and animals (and people, of course).
HFC's will somewhat damage the ozone. But they will not damage as much as CFC's.
Freons release fluorides which reach the ozone layer. They then form the oxides with ozone and deplete it.
CFC's can damage the ozone. They do it by reacting with it.
