Refrigerant Hazards

Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and/or throat. Wear eye protection when servicing the refrigerant system. Serious eye injury can result from eye contact with refrigerant.
Do not expose refrigerant to open flame. Poisonous gas is created when refrigerant is burned. An electronic type leak detector is recommended.
If accidental system discharge occurs, ventilate work area before resuming service. Large amounts of refrigerant released in a closed work area will displace the oxygen and cause suffocation.
The evaporation rate of R-134a refrigerant at average temperature and altitude is extremely high. As a result, anything that comes in contact with the refrigerant will freeze. Always protect shin or delicate objects from direct contact with refrigerant.
Liquid refrigerant is corrosive to metal surfaces. Follow operating instructions supplied with equipment being used.
