If a second-degree burn is larger than 2 to 3 inches, which is an appropriate first-aid response?
wrap the burned area loosely in a clean, dry bandage.

elevate the burned area.

submerge the burned area in cold water.

call 911.

Immediately call 911. Until an emergency unit arrives, take the following actions:
Elevate the burned area, above heart level if possible.
Cover the area of the burn, use a cool, moist bandage or a clean piece of cloth.

Don't submerge the large severe burned areas in cold water, doing so will worsen the situation, doing so could cause a serious loss of body heat (hypothermia) or a drop in blood pressure and decreased blood flow (shock).
