What is the first action you should take if someone is being electrocuted?

The first action to take if someone is being electrocuted is to turn off the power source. This is crucial because approaching a person who is still in contact with the electric current poses a risk of injury or death to the rescuer as well. By ensuring the power source is turned off, the risk of further electric shock is eliminated, which is vital for the safety of both the victim and the rescuer.

While calling for help and performing CPR are also important steps, they should only be initiated after ensuring that the scene is safe and the power has been turned off. Moving someone who is still being electrocuted can be extremely dangerous, as it can expose you to the same electric shock. Therefore, ensuring that the power is cut off first allows for a safe environment to perform subsequent rescue steps.
