Oil burns, what to do?

Suggestion: The patient needs to wash the wound under cold flowing water for about 30 minutes. If the wound is still painful, it can be soaked in cold water for a while. If the wound has blisters, small blisters can be absorbed by themselves and do not need to be treated. If it is a large blister, it is necessary to use a sterile syringe to extract the liquid first and then disinfect it.
