Use great care to avoid contact with liquid refrigerant gas being recovered 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
