Before servicing the vehicle, please follow these precautions.
Wear protective glasses and impermeable gloves, since there is a risk of burn and frost injuries.
If the skin comes into contact with the refrigerant, the exposed areas should be bathed in cold water and treated like a burn.
Should the coolant get into the eyes, rinse thoroughly with water for at least 10 minutes.
Refrigerant must not intentionally be released into the atmosphere. If, however, the refrigerant is unintentionally released in the premises, open and ventilate well before continuing work.
Gases that are formed when heating a refrigerant are a health hazard and can have a serious effect on the lungs.
Work should commence as soon as possible after emptying the A/C system as residual oil may emit refrigerant vapor that could collect and leak out if the work is delayed.
Smoking and open flames must not occur when handling refrigerants.
Refrigerant containers must not be exposed to heating, because the pressure will then increase resulting in the risk of explosion.
Compressed air mixed with R-134a forms a combustible vapor. The vapor can burn or explode causing serious injury. Never use compressed air to pressure test R-134a service equipment or a vehicle air conditioning system.
Air conditioning refrigerant or lubricant vapor can irritate eyes, nose, or throat. Be careful when connecting service equipment. Do not breathe refrigerant or vapor.
Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.
