1. Stay safe
2. Do not try to rescue a victim near active high voltage lines
3. If you can do so safely, turn off the electrical current (by unplugging the cord, turning off the circuit breaker or main switch)
4. Call for help
5. If it is dangerous to turn off the current, use a non-conducting item such as a wooden stick, chair or rug to push the victim far from the source of the current. Do not use a wet or metal object. If possible, stand on something dry and that doesn't conduct electricity, such as wood or folded newspapers.
6. When the victim is away from the source of the current and it is safe for you to approach, check the person's airway, breathing, and pulse. If either has stopped or seems dangerously slow or shallow, commence CPR.
7. If the victim has sustained electrical burns, remove any clothing that comes off easily, and rinse the burned area in cool running water until the pain subsides. Give first aid for burns.
8. If the victim is faint, pale, or shows other signs of shock, lay him or her down, with the head slightly lower than the trunk of the body and the legs elevated, and cover him or her with a warm blanket or a coat.
9. Stay with the person until medical help arrives.
10. Electrical injury is frequently associated with explosions or falls that can cause additional severe injuries. You may not be able to notice all of them. Do not move the person's head or neck if the spine may be injured.
DO NOTs
Do NOT touch the victim with your bare hands if they are still in contact with the source of electricity
Do NOT apply ice, butter, ointments, medications, fluffy cotton dressings, or adhesive bandages to a burn
Do NOT remove dead skin or break blisters if the person has been burned
After the power is shut off, do NOT move the person unless there is a risk of fire or explosion
