Electrical shock emergency guide
Danger of electrical shock depends on current, voltage and path through the body as well as a person's overall health and quick treatment. Call 911 if any of these symptoms occur:
- Cardiac arrest
- Heart rhythm problems
- Respiratory failure
- Muscle pain and contractions
- Numbness and tingling
While waiting for medical help
- Look first. Don't touch. The person may still be in contact with the electrical source. Touching the person may pass the current through you.
- Turn off the source of electricity, if possible. If not, move the source away from you and the person, using a nonconducting object made of cardboard, plastic or wood.
- Check for signs of circulation (breathing, coughing or movement). If absent, begin cardiopulmonary resuscitation (CPR) immediately.
- Prevent shock. Lay the person down and, if possible, position the head slightly lower than the trunk, with the legs elevated.
After coming into contact with electricity, the person should see a doctor to check for internal injuries, even if he or she has no obvious signs or symptoms.
- Don't touch the person with your bare hands if he or she is still in contact with the electrical current.
- Don't get near high-voltage wires until the power is turned off. Stay at least 20 feet away — farther if wires are jumping and sparking.
- Don't move a person with an electrical injury unless the person is in immediate danger.
