Which is the first step to take if a person is receiving an electrical shock?

The first step to take if a person is receiving an electrical shock is to ensure your own safety by turning off the source of electricity, if possible, or by using a non-conductive object to separate the person from the electrical source. Never touch the person directly while they are still in contact with the electrical source, as this could put you at risk as well. Once the source is disconnected, check the person for responsiveness and call emergency services if needed. Administer CPR if they are unresponsive and not breathing.
