Rush a person with an electrical or chemical burn to the nearest health unit IMMEDIATELY. Electrical burns often cause serious injury to organs inside the body that may not show on the skin. Flush chemical burns with large amounts of cool water. Take off any clothing or jewelry that has the chemical on it. DO NOT put any ointment on the burn-this could start a chemical reaction that may make the burn worse. Wrap the burn with dry, sterile gauze or a clean cloth until you receive medical help.
