If someone comes in contact with an indoor electrical circuit, immediately shut off the power at its source. Don't make contact with the victim. Touching the victim makes you a part of the path for current to flow to ground. Free the person or get the circuit away from them by using items made from nonconductive materials, such as wood or rope. Make sure you are standing on a dry surface and that your hands are not wet. Call emergency medical help to administer medical attention and an electrician to check or repair the circuit as soon as possible.
