After being scalded by hot oil, first, you should quickly move away from the hot oil. If oil splashes onto your clothes, carefully remove the oil-soaked clothing, including pants, shoes, and socks. Rinse the affected area with running water for more than half an hour to reduce the burning sensation and pain. If the scald manifests as local redness or small blisters, you can apply burn ointment to the surface. Try not to break the blisters or the epidermis to avoid bacterial infection. If blisters have already formed, under strict sterilization, you can use a sterilized needle to drain the blister fluid and then cover the wound with gauze to protect it from water. If the blisters are relatively large, it is advisable to go to the hospital burn department for examination, treatment, and care.
