Safety Regulations When Handling Refrigerant R134a

The refrigerant R 134a which is used is known as a safety refrigerant. This means that this refrigerant is nonflammable, non-explosive, non-toxic, non-irritating, odorless and tasteless. Despite this, you should still follow the points below:

WARNING:
Danger of injury as a result of contact with liquid or gaseous refrigerants.
- Wear rubber gloves to protect your hands.
- Treat affected skin in the same way as in the case of freezing. Rinse immediately with cold water and then consult a physician.
- Wear safety goggles to protect your eyes.
- If refrigerant still gets in your eyes, consult a physician immediately.

CAUTION:
Danger of fire due to the air-conditioning system heating up from sunlight shining into the vehicle or during welding and soldering work.
- When carrying out repairs on the air-conditioning system, the system must be emptied by suction and the refrigerant must be purified. Chlorine-free refrigerants must also not be allowed to escape into the atmosphere and must be disposed of correctly.
- Due to their chemical composition, different refrigerants must not be mixed with each other. This also applies for smaller quantities.
- No welding, soldering or hot-air heating may take place on parts of the filled air-conditioning system or in its immediate vicinity.
- Make sure that parts of the air-conditioning system do not heat up during welding or soldering work on the vehicle.
- While drying after painting work, the temperature burden on the vehicle must not exceed two hours at a maximum temperature of 80 degrees C.
- Whether or not the system is filled with refrigerant, the heating causes a very strong overpressure which can cause damage to the system or even lead to an explosion.
- R 134a is completely non-toxic at normal temperatures, but it decomposes upon contact with a flame or at high temperatures.
- Refrigerant bottles must not be thrown and must not be subjected to direct sunlight or other heat sources for an extended period when full.
- The maximum permissible temperature of a filled refrigerant bottle must not exceed 45 degrees C.
