What precaution should be taken when working with electrical wiring?

1. Use metal ladders

2. Work in wet conditions

3. Ensure the power is off

4. Wear loose clothing

The correct answer is: Ensure the power is off

When working with electrical wiring, ensuring that the power is off is a critical safety precaution. This action significantly reduces the risk of electrical shock or electrocution, which can occur if someone inadvertently makes contact with live wires while working on a circuit. Disconnecting the power supply allows the individual to inspect, repair, or replace wiring safely. Depending on the nature of the wiring work being done, using a voltage tester to confirm that no current is flowing is also advisable. Using metal ladders, particularly near electrical wiring, poses an increased risk of completing a circuit with a potential hazardous source. Working in wet conditions can exacerbate this risk, as moisture can conduct electricity and lead to more serious accidents. Wearing loose clothing is not recommended either, as it can catch on tools or electrical equipment, posing both a safety hazard and an additional risk when working with electrical systems. Therefore, confirming that the power is off is the fundamental safety measure that should always be taken.
