What is a recommended practice before beginning electrical work on a circuit?

Turning off and locking out the circuit power before beginning any electrical work is essential to ensure safety. This practice is part of a broader safety protocol known as Lockout/Tagout (LOTO), which is critical in protecting workers from accidental energization of circuits they are working on. By de-energizing the circuit and using a lockout device, it prevents anyone from inadvertently turning the power back on while work is being performed, reducing the risk of electrical shock or injury. This step is fundamental in creating a safe work environment when dealing with electrical systems.

While ensuring tools are ready, reading safety guidelines, and wearing personal protective equipment are all important practices, they cannot substitute the necessity of first ensuring that the circuit is de-energized. Prioritizing power disconnection directly addresses the immediate danger that electricity poses, making it the most crucial step before proceeding with any electrical tasks.
