Always wear goggles when working on air conditioning systems. The system is under pressure at all times, engine running or not. Escaping Freon-12 (C C12F2 Dichloro Difluoro Methane) can cause freezing of human flesh.Do not smoke while working on air conditioning systems. Inhaling Freon-12 through any smoking material, although not toxic or flammable, can generate phosgene gas and cause violent illness. Also, heat must never be applied to a charged system. See Air Conditioning And Heating Service Manual, Form No. SENR3334, for more information on removal and installation of lines and refrigerant from the system.
