Your best bet may be to call 911. The electric company will be notified so that the power can be shut off. A victim who has fallen from a height or sustained a severe shock causing multiple jerks, may have a serious neck injury and should not be moved without first protecting the neck. Children are not often seriously injured by electricity. The person could even be in cardiac arrest.
Burns are usually most severe at the points of contact with the electrical source and the ground.
The hands , heels , and head are common points of contact. In addition to burns, other injuries are possible if the person has been thrown clear of the electrical source by forceful muscular contraction. Consideration should be given to the possibility of a spine injury. The person may have internal injuries especially if he or she is experiencing any shortness of breath, chest pain, or abdominal pain. Pain in a hand or foot or a deformity of a part of the body may indicate a possible broken bone resulting from the electric shock.
