Question

which is the first step you should take in checking for burns?
call 9 - 1 - 1 or the local emergency number.
check to see if the scene is safe.
cool the burned area to stop the burning.
dry the burned area.

Explanation:

When dealing with burns, the first priority is personal safety. Checking the scene ensures that you (the helper) and the burned person are not in further danger (e.g., from a fire still burning, electrical hazards if it's an electrical burn - like near exposed wires). Only after confirming safety can other steps like calling emergency services (if needed), cooling the burn (after safety check and depending on burn type), or drying (a later step in some burn care) be considered.

Answer:

Check to see if the scene is safe.
