30 AIRCONDITIONING REFRIGERANT (R 134a ) (Tetraflouroethane, CF3-CH2F) R134a refrigerant has been filled in the airconditioning system for this vehicle. It is a hydroflurocarbon (HFC) which has no ozone destructive potential and its global warming potential is very much lower than that of R 12 refrigerant. Form ...................................... Gas. COLOUR................................. Colourless. Smell ..................................... Slightly of ether. Crystallisation temperature ..... -117 0 C. Boiling temperature ................. -26 0 C. Safety Precautions: It is a safe refrigerant, i.e. non-flammable, non explosive, non-irritating and without smell. The following precautions should to be taken while handling this refrigerant: * Avoid any form of contact with liquid refrigerant. Wear safety glasses for eye protection. In case refrigerant gets into your eyes, immediately seek medical help. Do not rub. * In the event of work involving the refrigerant circuit, refrigerant must not escape into the atmosphere. * Suitable suction extraction system or reprocessing systems are to be used. * Refrigerant must not be released in confined spaces. As it is heavier than air, the danger of asphyxiation exists in any assembly pits in the area. * Under no circumstances may parts of the system be cleaned from inside with superheated steam or compressed air. Only use nitrogen for cleaning. * Refrigerant is completely non - toxic at normal temperatures, however it decomposes upon contact with flames or higher temperatures, to form hydrogen chloride and hydrogen fluoride. These products of decomposition are hazardous to health. Therefore, under no circumstances, should welding be carried out on the closed system or in its close proximity. Ozone destructive potential Global warming potential l Relative potential * Switch off the system if a par t of the air - conditioner system is damaged or leaking, due to some reason for example, a vehicle accident. This is to avoid damage to the compressor running in the absence of refrigerant in the circuit. Fig. 41
