If you have experienced a minor electric shock on your hand, you should follow these steps:

1. Turn off the source of electricity or move it away from you using a non-conducting object made of wood, cardboard, or plastic.
2. Break contact with the electrical source and do not touch it.
3. Check yourself for any injuries, such as burns or broken bones. If you have any visible burns, put the burnt area under running water for at least 20 minutes, then cover it with a sterile gauze bandage or a clean cloth. Do not use a blanket or towel, as loose fibers can stick to the burns.
4. Seek medical attention if you have any symptoms, such as chest pain, shortness of breath, abdominal pain, or if you have lost consciousness.

If you have experienced a high voltage shock, it is important to call 911 immediately. If someone else has experienced an electric shock and is not breathing or does not have a pulse, perform CPR if you know how to do it safely, and wait for emergency services to arrive.
