Dichloro-I I I-trifuloroethane 2 2 (HCFC-123)

A concise assessment of the risks to human health and the environment posed by exposure to 2 2-dichloro-1 1 1-trifluoroethane (HCFC-123) a volatile liquid used as a refrigerant in commercial and industrial air-conditioning installations in gaseous fire extinguishers as a foam-blowing agent and in metal and electronics cleaning. Although HCFC-123 is known to contribute to ozone depletion the significance of its role in global warming is far smaller than that of chlorofluorocarbons and bromofluoro
