In the event of a large release of R-12 or R-22 in a contained area, which safety measure is required?

When a large amount of refrigerant like R-12 or R-22 is released in a contained space, the immediate danger is oxygen deficiency. These gases are heavier than air and can quickly accumulate, displacing the breathable atmosphere. The safest action is to either evacuate the area or enter only with a self-contained breathing apparatus that provides its own air supply. This protects you from both the lack of oxygen and exposure to the refrigerant. Goggles and gloves don’t address the critical risk of asphyxiation in a confined space, and assuming respiratory protection isn’t needed or that a dust mask would be enough is incorrect. A dust mask does not protect against inhaling dense refrigerant vapors, and air-purifying respirators don’t supply oxygen in an oxygen-deficient environment.
