Stop any bleeding from the body and loosen tight clothing. Induce artificial respiration if breathing is difficult. For burns, direct a cold water jet on the area and cool it further by gently pouring more cold water or using a cold compress. Remove constricting jewelry immediately. Keep the burned area elevated and cover with antiseptic-soaked gauze without touching it directly. Seek medical help and rest in an airy place. If poison is ingested, induce vomiting with saltwater.
