Where It Comes From
Leaks or venting from older refrigeration systems (e.g., blends like R-502), legacy stockpiles, and improper equipment disposal; lingering background levels in outdoor air from past use [2].
How You Are Exposed
Inhaling vapors during equipment leaks or servicing, especially in poorly ventilated or confined spaces; contact with cold liquid can cause frostbite [1].
Why It Matters
Depletes the ozone layer (more UV reaching people and ecosystems) and contributes to climate change; high concentrations can cause dizziness, headache, irregular heartbeat, or loss of consciousness by displacing oxygen [1][2].
Who Is at Risk
Refrigeration technicians, workers in mechanical rooms or confined spaces, and people with heart conditions during high exposures [1].
How to Lower Your Exposure
Replace or properly maintain old equipment; use certified technicians for recovery/servicing; ensure ventilation and leak detection; never intentionally inhale; follow local rules for disposal and refrigerant recovery [1][2].
