PPE Safety Reference
Select a refrigerant to view required PPE, exposure limits, and first-aid guidance based on OSHA, ASHRAE, and ACGIH standards.
Ceiling limit in some jurisdictions; cardiac sensitization at very high conc. ASHRAE 34 OEL 1000 ppm (pre-2022 addendum showed 5000 ppm ASHRAE 34 RCL-based). Montreal Protocol CFC - fully phased out.
- Eyes: Chemical splash goggles; face shield for transfer operations
- Hands: Insulated thermal/cryogenic gloves when handling liquid (boils near room temp at -23.8°F); chemical-resistant gloves
- Body: Long sleeves; chemical-resistant apron or coveralls for bulk handling
- Respiratory: No respirator required for routine work below OEL; SCBA or airline respirator if spill or confined-space entry above 1000 ppm
- Feet: Steel-toe leather boots
- Skin: Flush with lukewarm water 15+ min; remove contaminated clothing; treat frostbite - do not rub; seek medical attention if symptoms persist
- Eyes: Flush with water 15+ min holding lids open; seek immediate medical attention
- Inhalation: Remove to fresh air; administer oxygen if breathing labored; CPR if not breathing; call 911. Avoid exertion - cardiac sensitization risk
- Ingestion: Not applicable (gas/liquid at room temp); if liquid ingested seek immediate medical attention
Ventilate area; no ignition sources (refrigerant itself non-flammable, but thermal decomposition produces phosgene/HF/HCl at high temps); evacuate if above OEL
Evacuate non-essential personnel min 25 ft; ventilate; PPE per above; do not enter low-lying areas (vapor heavier than air); report releases >100 lbs per EPA CAA
Non-flammable; decomposition products (HCl, HF, phosgene) toxic - use SCBA. Class B/C extinguisher for surrounding materials
