Safety Precautions When Handling Refrigerant

There is a risk of asphyxiation and poisoning from refrigerant.

Refrigerant fumes can cause problems ranging from a dry cough and nausea to asphyxiation and poisoning.

-- Never inhale refrigerant fumes.

-- Only work on the refrigerant circuit in well-ventilated areas and protect refrigerant cylinders.

-- Never work near basement staircases or other low-lying areas.

-- Switch on exhaust extraction.

There is a risk of frostbite from refrigerant.

When working on the A/C system, refrigerant under pressure can escape. Frostbite on the skin and other parts of the body is possible.

-- Wear safety gloves.

-- Wear protective eyewear.

-- Evacuate or drain refrigerant and open the refrigerant circuit immediately.

-- If more than 10 minutes elapse after extracting or draining the refrigerant and the refrigerant circuit has not been opened, extract or drain the refrigerant again. Pressure develops in the refrigerant circuit due to evaporation.
