An electrical injury can occur to the skin or internal organs when a person is directly exposed to an electrical current.

The human body is a good conductor of electricity. Direct contact with electrical current can be fatal. While some electrical burns look minor, there still may be serious internal damage, especially to the heart, muscles, or brain.

About 1,000 people die annually of electric shock in the United States.

The outcome of an electric shock to an individual depends on the intensity of the voltage to which the person was exposed, the route of the current through the body, the victim's state of health, and the speed and adequacy of the treatment.

Electric current can cause injury in three main ways:

Symptoms may include:

1. If safely possible, shut off the electrical current. Unplug the cord, remove the fuse from the fuse box, or turn off the circuit breakers if possible. Often, simply turning off the appliance itself will not stop the flow of electricity.

2. Call for medical help.

3. If the current can't be turned off, use a non-conducting object, such as a broom, chair, rug, or rubber doormat to push the victim away from the source of the current. Don't use a wet or metal object. If possible, stand on something dry and non-conducting, such as a mat or folded newspapers. Do not attempt to rescue a victim near active high-voltage lines.

4. Once the victim is free from the source of electricity, check the victim's airway, breathing, and pulse. If either has stopped or seems dangerously slow or shallow, initiate first aid (CPR).

5. If the victim has a burn, 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.

6. If the victim is faint, pale, or shows other signs of shock, lay the victim down, with the head slightly lower than the trunk of the body and the legs elevated, and cover the person with a warm blanket or a coat.

7. Stay with the victim until medical help arrives.

8. Electrical injury is frequently associated with explosions or falls that can cause additional traumatic injuries, including both obvious external injuries and concealed internal injuries. Avoid moving the victim's head or neck if a spinal injury is suspected. Administer appropriate first aid as needed for other wounds or fractures.

Call for emergency medical help if the victim is unconscious, confused, has difficulty breathing, has skin or mouth burns, or was in contact with a high-voltage source.
