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 dry, no-conducting 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.
