Safety Profile
Hazard Codes: 
F
Risk Statements: 40-59
R40:Limited evidence of a carcinogenic effect.
R59:Dangerous to the ozone layer.
Safety Statements: 23-59
S23:Do not breathe vapour.
S59:Refer to manufacturer / supplier for information on recovery / recycling.
Mildly toxic by inhalation. Experimental reproductive effects. Mutation data reported. An asphyxiant in high concentrations. At elevated pressures, 50% mixtures with air are combustible although ignition is difficult. When heated to decomposition it emits toxic fumes of F− and Cl−.
Standards and Recommendations
OSHA PEL: TWA 1000 ppm

Specification
Difluorochloromethane , its cas register number is 75-45-6. It also can be called Chlorodifluoromethane ; Fluorocarbon 22 ; Freon R-22 ; and Freon 22 . Difluorochloromethane (CAS NO.75-45-6) is shipped as a liquefied gas under its own vapor pressure, and is noncombustible. Difluorochloromethane can asphyxiate by the displacement of air. Contact with the liquid can cause frostbite.
