· Use care to prevent refrigerant from touching your skin or eyes; wear protective goggles and nonleather gloves when
servicing Air Conditioning systems. Liquid refrigerant, when exposed to air, quickly evaporates and will freeze skin
or eye tissues. Serious injury or blindness may result if you come in contact with liquid refrigerant.
· Refrigerant R-134a A/C systems should not be pressure tested or leak tested with compressed air. Combustible
mixtures of air and R-134a may form, resulting in a fire or explosion, which could cause personnel injury or

· Refrigerant is odorless. As a result, all of it may leak away and not be noticed until system stops cooling. All
vehicle refrigerant systems lose some refrigerant depending on condition of system. Higher loss rates signal a
need to locate and repair leaks.
· Leaks are most often found at compressor hose connections and at various fittings and joints in system. If unap-
proved replacement hoses are installed, refrigerant can be lost through hose permeation.
Visually inspect refrigerant system for A/C lubricant leakage and corrosion and damage to lines, hoses, and other com-
Visually inspect lowest points of fittings, hoses, and lines for indication of lubricant leakage.
Use a leak detector in accordance with manufacturer's instruction manual and check for refrigerant leakage at hose con-
nections, fittings, and areas where leakage might occur. If leaks are indicated, notify Direct Support Maintenance of leak in A/
