Handling Refrigerant

CAUTION: Avoid breathing the A/C Refrigerant 134a (R-134a) and the lubricant vapor or the mist. Exposure may irritate the eyes, nose, and throat. Work in a well ventilated area. In order to remove the R-134a from the A/C system, use service equipment that is certified to meet the requirement of SAE J 2210 (R-134a recycling equipment). If an accidental system discharge occurs, ventilate the work area before continuing service. Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.

Important
^ R-12 refrigerant and R-134a refrigerant must never be mixed, even in the smallest of amounts, since they are incompatible with each other. If the refrigerants are mixed, compressor failure is likely to occur.
^ Use only specified lubricant (PAG) for the R-134a A/C system and R-134a components. If lubricants other than those specified are used, compressor failure is likely to occur. All fittings and O-ring seals should be coated with clean 525 viscosity refrigerant oil to provide a leak-proof seal and to aid in assembly and disassembly.
^ Do not store or heat refrigerant containers above 125°F (52°C).
^ Do not heat a refrigerant container with an open flame. If the container must be warmed, place the bottom of the container in a pail of warm water.
^ Do not intentionally drop, puncture, or incinerate refrigerant containers.
^ Refrigerant will displace oxygen, so be certain to work in well ventilated areas to prevent suffocation.
^ Do not introduce compressed air to any refrigerant container or refrigerant component, because contamination will occur.
^ If it is necessary to carry a container of Dot CFR Refrigerant-134a in a vehicle, do not carry it in the passenger compartment.

All Refrigerant-134a disposable (colored Blue) containers are shipped with a heavy metal screw cap to protect the valve and safety plug of the container from damage. It is a good practice to replace the cap after each use to continue protection.
