Precautions on Servicing A/C System

Precautions on Servicing A/C System

WARNING:
Should refrigerant HFC-134a (R-134a) is exposed to your eye(s), consult a doctor
immediately.
- Do not use your hand to rub affected eye(s). Instead, use fresh cold water to splash it over affected area to thus gradually raise its temperature above the freezing point.
- Obtain proper treatment as soon as possible from a doctor or eye specialist. Should liquid refrigerant HFC-134a (R-134a) is exposed to your skin, such affected part should be treated in the same manner as when skin is frostbitten or frozen.
