Regulations & SafetyQuestion 48 of 240

While transferring liquid refrigerant, a technician gets a splash on bare skin. What injury is most likely, and what is the correct first aid?

a.No injury; liquid refrigerant is harmless on skin
b.Frostbite; flush with lukewarm water, get care
c.A chemical burn; rinse with vinegar
d.An electrical burn; apply ice directly

Explanation

Liquid refrigerant evaporates rapidly and absorbs heat from the skin, causing frostbite, so the correct first aid is to flush the area with plenty of lukewarm (not hot) water and seek medical attention. Vinegar is for chemical exposures, ice would worsen frostbite, and liquid refrigerant is definitely not harmless. Wearing gloves and safety glasses prevents most of these injuries.
