Is CFC-12 still used?
While use of CFC-12 in new vehicles has been banned since 1994, some vehicles built before then may still use it if they have not already been retrofitted to a non-ozone depleting refrigerant and they are still on the road.
Is CFC-12 toxic?
CFCs were developed during the 1920s as replacements for more toxic refrigerants such as NH3, CH3Cl, and SO2. Dichlorodifluoromethane (CFC-12) is a non-flammable and unreactive gas that makes a good refrigerant….What is a CFC?

What CFC-12?
Dichlorodifluoromethane (R-12) is a colorless gas usually sold under the brand name Freon-12, and a chlorofluorocarbon halomethane (CFC) used as a refrigerant and aerosol spray propellant.
What happens if you break the Clean Air Act?
The equipment uses HCFC refrigerants.
Is R-12 illegal?
R-12 is a colorless and odorless CFC refrigerant that was completely banned from production by 1996 under the Montreal Protocol for depleting the ozone.
Is there a reward for reporting EPA violations?
While the Environmental Protection Agency (EPA) and other federal and state agencies can impose fines or seek damages from polluters and others under a number of different laws, the environmental laws do not generally provide financial rewards for whistleblowers who report violations.
Who has violated the Clean Air Act?
The Department of Justice, the Environmental Protection Agency (EPA), and the State of California announced today a settlement with Fiat Chrysler Automobiles N.V., FCA US, and affiliates (Fiat Chrysler or FCA) for alleged violations of the Clean Air Act and California law.
Can CFCs be removed?
As CFCs have no significant tropospheric removal process, but are rapidly photolysed above the lower stratosphere, the timescale for their removal is set mainly by the rate at which air is transported from the troposphere into the stratosphere.
Can a CFC-12 be removed from a refrigerant system?
The original CFC-12 must be removed from the system using EPA-approved recovery-only or recovery and recycling equipment prior to charging with the new refrigerant. This procedure will prevent the contamination of one refrigerant with another.
Is it legal to use CFC-12 in new cars?
While use of CFC-12 in new vehicles has been banned since 1994, some vehicles built before then may still use it if they have not already been retrofitted to a non-ozone depleting refrigerant and they are still on the road.
What are the effects of CFCs on the atmosphere?
The strength of CFC absorption bands and the unique susceptibility of the atmosphere at wavelengths where CFCs (indeed all covalent fluorine compounds) absorb creates a “super” greenhouse gas (GHG) effect from CFCs and other unreactive fluorine-containing gases such as perfluorocarbons, HFCs, HCFCs, bromofluorocarbons.
Can a CFC-12 retrofit be used with HCFC-22?
When retrofitting any system with such a device to use a new refrigerant, the technician must also install a high-pressure shutoff switch. This switch will prevent the compressor from increasing the pressure to the point where the refrigerant is vented. HCFC-22, a component in some blends, can seep out through traditional CFC-12 hoses.
