Technician Safety Information

The refrigerant R-134a is a hydro-fluorocarbon refrigerant that is non-corrosive, non-explosive, non-flammable, heavier than air and has a slight ether-like odor.

When drained, R-134a must be collected into a container specifically designed for R-134a, as it is not compatible with R-12 or oil. Liquid R-134a, at normal atmospheric pressures and temperatures, evaporates very rapidly and will freeze anything it contacts. Should any liquid refrigerant come in contact with skin or eyes, immediately flush eyes and/or skin with plenty of water for 15 minutes; call a doctor. Remove contaminated clothing and shoes.
R-134a is always under pressure. Heat should not be applied to any part of the system as this could cause excessive pressure build-up.

WARNING: To avoid a dangerous explosion, keep away from open flames, glowing metal surfaces, blow torch, steam cleaning and welding. Ensure containers are never heated above 125°F.

R-134a should not be mixed with air for leak testing or used with air above atmospheric pressure for any purpose. R-134a is combustible when mixed with high concentrations of air and higher pressures.
