What is the first step to take when administering first aid for electrical shock?

When administering first aid for electrical shock, the first step is to ensure safety by turning off the power source. This is critical because approaching a victim who is still in contact with an electrical current can pose significant danger to both the victim and the rescuer. If the power is not turned off, there is a risk of the rescuer also becoming a victim of electrical shock, which could lead to further complications.

Only after ensuring that the area is safe by de-energizing the electrical source should a rescuer assess the victim's injuries. This prioritization of safety ensures that help can be provided without additional harm. Once safety is established, calling for emergency help and then assessing the injuries or performing CPR can follow, depending on the condition of the victim.
