Safety Precautions When Working On Air Conditioning System

There is a risk of explosions because of ignition sources.

Risk of explosion due to ignition sources near A/C systems and refrigerant canisters. Leaking refrigerant can ignite and cause an explosion. Severe bodily injury or death due to explosions is possible.

• Do not bring any ignition sources near A/C systems and refrigerant cylinders.

Risk of suffocation and poisoning from refrigerant

Refrigerant fumes can cause problems ranging from a dry cough and nausea to asphyxiation and poisoning. Refrigerant is heavier than air and accumulates in low-lying areas.

• Do not inhale refrigerant vapors.
• Only work on the refrigerant circuit in well-ventilated spaces/areas.
• Store refrigerant canisters in well-ventilated spaces.
• Do not work in and near low-lying areas.
• Turn on the exhaust extracting system.

There is a risk of frostbite from refrigerant.

Refrigerant can escape under pressure when working on the A/C system. Frostbite of skin and other parts of the body possible.

• Wear safety gloves.
• Wear protective eyewear.
• Extract or drain refrigerant and immediately open the refrigerant circuit.
• If the extraction or drainage process has been more than 10 minutes ago and the refrigerant circuit has not been opened, then extract or drain the refrigerant again. Pressure has built up in the refrigerant circuit due to evaporation.
