What safety precaution should be taken when working with electricity?

• A. Always turn off power at the source and verify with a multimeter
• B. Wear rubber gloves and boots only
• C. Use wooden tools to handle cables
• D. Ensure that all lights are turned off

Answer: (A)

The correct answer emphasizes the importance of turning off the power at the source before beginning any electrical work. This precaution is crucial because it minimizes the risk of electric shock or electrocution. After turning off the power, using a multimeter to verify that there is no voltage present adds an essential step in ensuring safety. This double-checking provides a reliable confirmation that the circuit is de-energized, allowing the worker to proceed with their task safely. While wearing rubber gloves and boots can provide some protection against electric shock, relying solely on personal protective equipment without ensuring that the power is turned off does not guarantee safety. Using wooden tools can help reduce the risk of conducting electricity, but it is not a substitute for turning off the power. Lastly, simply turning off lights does not ensure that the circuit is de-energized, as there could be live wires or other loads that remain energized. Thus, the correct approach is to thoroughly disable the power source and verify with a multimeter.
