Regulations & Safety第 48 / 240 题
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.A chemical burn; rinse with vinegar
b.Frostbite from rapid evaporation; flush with plenty of lukewarm water and seek medical care
c.An electrical burn; apply ice directly
d.No injury; liquid refrigerant is harmless on skin
解析
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.
