Always wear goggles when the air conditioning system is opened. This system is charged with Freon-12 (CCL2F2 Dichlorodifluoromethane) which is not toxic or flammable. There is however, reason for caution. When Freon-12 makes contact with a flame, lethal phosgene gas is made. INHALING FREON THROUGH A LIGHTED CIGARETTE CAN CAUSE VIOLENT ILLNESS. This system is under pressure at all times, engine running or not. HEAT MUST NEVER BE PUT ON A CHARGED SYSTEM. See Air Conditioning And Heating Service Manual Form No. SENR7454 for more information on procedures and safety requirements on removal and installation of lines and refrigerant from the system.
