Electrical burns do not always show on the skin at all, and when they do they often appear minor. However, damage can extend deep into the tissues and organs beneath your skin. If a strong electrical current has passed through your body, internal damage can result including heart rhythm disturbance or cardiac arrest. Sometimes the impact of an electrical jolt can throw you or cause you to fall and sustain fractures or other related injuries.
They may still be in contact with or surrounded by the source of the electrical current. If you touch or go near them without checking for this first, the electrical current could pass through you, too.
Dial 911 if the victim is in pain, confused, not breathing or unconscious.
