Introduction:

Chlorodifluoromethane is a non-flammable, colourless and nearly odourless gas under normal conditions. A large proportion is used as a chemical intermediate and therefore not emitted into the atmosphere. Other important uses are in refrigeration and in air conditioning systems; with present practice, most of the chlorodifluoromethane so used will eventually be emitted into the atmosphere.

Its moderate water solubility and low octanol/water partition coefficient indicate a negligible bioaccumulation potential. Contamination of water and food would not be expected from its physical and chemical properties and has not been reported.

Cas Registry Number:
75-45-6

Conversion factors:
1 ppm = 3.54 mg/m3
1 mg/ m3 = 0.282 ppm

Main applications

-Refrigerant (pure or in blends for CFC drop-ins)
-Blowing agent component for polyurethane foams (PUR) and for extruded polystyrene foams (XPS)

Occupational health:

The national permissible occupational exposure limits vary between 1,750 and 3,500 mg/ m3 (8hr TWA). It is concluded that this provides adequate health protection.
