What is the first proper response to the electrocution of a person?

In the event of a person being electrocuted, the first proper response involves ensuring the safety of both the victim and the responder. Turning off the main switch is crucial because it eliminates the electrical current that is causing harm, preventing further injury to the victim and allowing for a safe approach.

Without this step, any attempts to assist the individual can lead to the rescuer also experiencing an electric shock. By cutting off the electrical source, you create a safe environment in which you can evaluate the victim and potentially perform lifesaving measures, such as calling for help or administering CPR if necessary. This step is foundational in emergency response protocols regarding electrical injuries.

Other options, while they may be important later in the response process, do not address the immediate danger posed by continuing electrical shock. Therefore, turning off the main switch is the most appropriate first action in this scenario.
