Page 6: Precautions For Handling Refrigerant For Air Conditioner
Precautions 1-4. Precautions for Handling Refrigerant for Air Conditioner Environmental Cautions: Air pollution due to gas release ● Safety Cautions If liquid gas is released, then body parts that come into contact with it may experience frostbite/blister/numbness. If a large amount of gas is released, then suffocation may occur due to lack of oxygen. If the released gas is heated, then noxious gas may be produced by combustion.
