What is the first action in the event of an electrical shock?

The first action in the event of an electrical shock is to disconnect the power source, if it is safe to do so. This is crucial because the primary threat to life following an electrical shock is the continued exposure to electrical current. By cutting off the power supply, you can prevent further injury to the victim, as well as to yourself and any other bystanders.

Additionally, handling the situation safely requires assessing the environment for potential hazards before taking action. If a person is still in contact with the electrical source, moving them or providing aid could lead to further injury or even fatality due to the risk of electrocution. Ensuring the power is off eliminates that immediate danger and lays the groundwork for providing necessary medical assistance.

Once the power is disconnected and it is safe to approach, further actions such as calling emergency services or performing CPR can be taken as needed based on the victim's condition.
