Page 3: Hydrofluorocarbons
E2618-HFC Rev 09.03.2021 Hydrofluorocarbons HFCs are relatively non-flammable, chemically stable, and nonreactive. Classification of halocarbon refrigerants Group Refrigerants Chlorofluorocarbons (CFC) R11, R12 Hydrochlorofluorocarbons R22, R141b, R142b (HCFC) Hydrofluorocarbons (HFC) R32, R125, R134a, R143a Hydrofluoroolefins (HFO) R 1234ez, R1234yf, R1336mzz Chlorine containing refrigerants (CFC and HCFC) are considered to be damaging to the ozone layer and contributing to the greenhouse effect. - Page 4 E2618-HFC Rev 09.03.2021 asphyxiation in confined spaces. At higher temperatures (>250°C) decomposition products may include hydrofluoric acid (HF) and carbonyl halides. An escape of refrigerant through a leak may damage the refrigerating facilities.
