Use great care to avoid contact with liquid refrigerant or refrigerant
gas being discharged from any container under pressure. Sudden
and irreversible tissue damage can result from freezing. Wear
thermal protective gloves and a face protector or safety glasses in
any situation where skin or eye contact is possible.
Prevent contact of refrigerant gas with flame or hot metal surfaces.
Heat causes the refrigerant to break down and form carbonyl
chloride (phosgene), a highly toxic and corrosive gas. In case of
refrigerant leaks, ventilate area immediately.
