What should you do first in case of an electrical shock?

• A. Call emergency services
• B. Disconnect the main power source
• C. Touch the person to see if they're okay
• D. Use a wet cloth to turn off the power

Answer: (B)

In the event of an electrical shock, the first step should be to disconnect the main power source. This is crucial because approaching the person who has experienced the shock while they are still in contact with the live electrical source can put you at risk of becoming a victim of the shock as well. By ensuring that the electricity is turned off, you create a safe environment to assist the person.

Taking this action not only protects you but also allows for safe access to the person in need. Once the power is disconnected, you can check on the individual's status and seek emergency assistance if necessary. Other alternatives, like using a wet cloth to turn off the power or touching the person to assess their condition, pose significant dangers and are ineffective measures in ensuring safety during such emergencies.
