Overview
Chlorodifluoromethane and chloropentafluoroethane is a mixture of the two colorless, nonflammable gases. The mixture may be mildly toxic by inhalation. It can asphyxiate by the displacement of air. Exposure of the container to prolonged heat or fire may cause it to rupture violently and rocket. It is used as a refrigerant gas.
