Safety Precautions

1. R-134a liquid refrigerant is highly volatile. A drop of it on the skin could result in localized frostbite. When handling the refrigerant, be sure to wear gloves.




2. If the refrigerant splashes into the eyes, wash them with clean water immediately. Always wear goggles or glasses to protect the eyes.
3. The R-134a container is a highly pressurized vessel. Never subject it to intense heal, and be sure that the temperature where it is stored is below 52 °C (125.6 °F).
4. A halide leak detector is often used to check the system for refrigerant leakage. R-134a, upon coming into contact with the flame, produces phosgene, a toxic gas. Always provide adequate ventilation.
