General Safety Instructions-
WARNING
Death or serious injury may result if personnel fail to observe safety precautions.
Use great care to avoid contact with liquid refrigerant or refrigerant gas being
discharged under pressure. Sudden and irreversible tissue damage can result
from freezing. Wear thermal protective gloves and a face protector or goggles in
any situation where skin-eye-contact is possible.
Prevent contact of refrigerant gas with flame or hot surfaces. Heat causes the
refrigerant to break down and form carbonyl chloride (phosgene), a highly
poisonous and corrosive gas.
