What hazards can refrigerants pose?
Refrigerants can cause cold-liquid injuries, inhalation hazards, oxygen displacement, pressure-release injuries, and—in some cases—fire or decomposition hazards.

What hazards can refrigerants pose?
Refrigerants can cause cold-liquid injuries, inhalation hazards, oxygen displacement, pressure-release injuries, and—in some cases—fire or decomposition hazards.
What should you check before servicing refrigerant equipment?
Identify the refrigerant and check its safety data sheet (SDS) and equipment instructions before starting work.
What is a key ventilation practice for refrigerant work?
Work in a well-ventilated area and use suitable mechanical ventilation when needed. Do not rely on smell to judge whether the air is safe.
What must happen before opening a pressurized refrigerant system?
Follow lockout/tagout and equipment procedures. Safely isolate and depressurize a system before opening it.
How should recovered refrigerant be collected?
Use recovery equipment approved for the refrigerant and a compatible, properly labeled recovery cylinder. Never mix refrigerants in a cylinder.
What does EPA Section 608 prohibit during covered work?
EPA Section 608 prohibits intentionally venting covered refrigerants during equipment service, repair, or disposal.
Which PPE helps protect during routine refrigerant service?
Use eye protection and insulated gloves suitable for refrigerant contact. Choose PPE based on the SDS, task risks, and employer procedures.
Why is an ordinary air-purifying respirator unsafe for an unknown leak area?
Respirators do not replace ventilation or make untrained entry into a leak area safe. An ordinary air-purifying respirator does not protect against oxygen deficiency.
How should refrigerant leaks be located?
Use a leak detector or another suitable leak-check method. Never use an open flame to locate refrigerant leaks.
What must be done after repairing a refrigerant leak?
Repair the cause of the leak, then verify that it has been corrected before returning the equipment to service.
What should you do first during a suspected significant leak?
Warn others, leave the affected area, and contact emergency services or the site emergency contact. Do not attempt an untrained, unequipped rescue.
What should you do after cold liquid refrigerant contacts skin?
Get medical help promptly. Do not rub the area or forcibly remove clothing frozen to the skin; follow the SDS and medical guidance.
