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 refrigerant to break down and form
carbonyl chloride (phosgene), a highly poisonous and corrosive gas.
