Contact with electrical current is potentially fatal. Electricity passing through the body can cause injury to the skin and internal organs. If electricity passes through the heart, the heart muscle may be damaged and the heart’s rhythm interrupted, leading to cardiac arrest. The signs and symptoms of electric shock include tingling, burns on the skin where the current entered or exited, muscle pain, headache, loss of consciousness, irregular breathing or lack of breathing, and cardiac arrest. The severity of the injury depends on the strength of the electric current and the path the current takes through the body. The person providing first aid to a victim of electric shock should not touch the individual’s body until the source of the shock is turned off. Because of the potential for internal injuries, victims of electrical injury should not be moved unless they are in immediate danger. The first-aid provider should monitor the victim for symptoms of shock. If the victim has stopped breathing and has no pulse, CPR should be performed after the airway, breathing, and circulation have been checked. When the victim’s vital signs are stable, the site of the burn should be treated using the same methods used for other burns.
