Heating and Air Conditioning: Service Precautions

A/C REFRIGERANT SYSTEM SERVICE WARNINGS

Using/Handling Unapproved Refrigerant

WARNING:Using a flammable refrigerant, such as OZ-12, in this vehicle is dangerous. In accident, the refrigerant may catch fire, resulting in serious injury or death. When servicing this vehicle, use only R-134a.Checking for system leaks on a vehicle that has been serviced with flammable refrigerant, such as OZ-12, is dangerous. Conventional leak detectors use an electronically generated arc which can ignite the refrigerant, causing serious injury or death. If a flammable refrigerant may have been used to service the system, or if you suspect a flammable refrigerant has been used, contact the local fire marshall or EPA office for information on handling the refrigerant.

Handling Refrigerant

WARNING:Do not allow the refrigerant to leak near fire or any kind of heat. A poisonous gas may be generated if the refrigerant gas contacts fire or such heat as from cigarettes and heaters. When carrying out any operation that can cause refrigerant leakage, extinguish or remove the above-mentioned heat sources and maintain adequate ventilation. Failure to follow these instructions may result in personal injury.Handling liquid refrigerant is dangerous. A drop of it on the skin can result in localized frostbite. When handling the refrigerant, wear gloves and safety goggles. If refrigerant splashes into eyes, immediately wash them with cold water and consult a doctor.

Storing Refrigerant

WARNING:The refrigerant container is highly pressurized. If it is subjected to high heat, it could explode, scattering metal fragments and liquid refrigerant that could seriously injure you. Store the refrigerant at temperatures below 40°C {104°F}. Failure to follow these instructions may result in personal injury.
