Safety Precautions When Handling Refrigerant
Risk of asphyxiation and poisoning from the refrigerant
Dry coughing and nausea due to suffocation and poisoning is possible due to refrigerant fumes.
-- Never breathe in refrigerant fumes.
-- Only perform procedures on the refrigerant circuit in well ventilated areas and store in refrigerant container.
-- Never perform procedures in and near basement staircases or other below ground areas.
-- Switch on the exhaust extracting system.
There is a risk of getting frostbite from the refrigerant.
Refrigerant can come out under pressure when working on the A/C system. Frostbite on the skin and other parts of the body is possible.
-- Wear safety gloves.
-- Wear protective eyewear.
-- Extract refrigerant and open the refrigerant circuit immediately.
-- If more than 10 minutes elapse after extracting the refrigerant and the refrigerant circuit was not opened, extract the refrigerant again. Pressure can develop in the refrigerant circuit due to evaporation.
