Action
Use great care to avoid contact with liq-
uid 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 pro-
tector 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 breakdown and
form carbonyl chloride (phosgene), a
highly toxic and corrosive gas.
