Abstract

1,2-Dichloro-1,1,2,2-tetrafluoroethane [76-14-2] and other partly halogenated chlorofluorocarbons (H-CFCs) are no longer approved in the European Union or in Germany. The derivation of the previous MAK value (maximum concentration at the workplace) of 1,2-dichloro-1,1,2,2-tetrafluoroethane by the German Senate Commission for the Investigation of Health Hazards of Checmical Compounds in the Work Area (MAK Commission) does not correspond to the current approach of the Commission. There are no new studies that would allow the MAK value to be revised. The Commission decided that a new evaluation is not of high priority. The MAK value and the other classifications are therefore suspended and the substance is listed in the Section II c of the List of MAK and BAT Values for substances no longer evaluated.
