What should be done to ensure the safety of workers when troubleshooting electrical systems?

The correct approach to ensuring the safety of workers when troubleshooting electrical systems is to always de-energize circuits. De-energizing circuits means that the electrical power is turned off before any work begins. This significantly reduces the risk of electric shock, arc flash, and other electrical hazards. By taking this precautionary step, technicians create a safer environment that allows for troubleshooting and repairs without the immediate danger posed by live electrical circuits.

In addition to this, locking out and tagging out (LOTO) procedures should be followed after de-energizing to prevent any accidental re-energization while maintenance is performed. This is a critical safety practice in electrical work and is essential to protect not only the technician but also anyone who may be nearby.

Working with power on is inherently risky, as it exposes technicians to potential hazards. Using only high-voltage tools does not inherently increase safety and could lead to dangerous situations if the tools are misused. Minimizing the wearing of protective gear contradicts safety standards, as protective gear is crucial in preventing injuries in the event of an accident. Therefore, de-energizing circuits is the best and safest practice when working on electrical systems.
