When is temporary de-energization of nearby electrical systems indicated?

When is temporary de-energization of nearby electrical systems indicated?

• A. Only when required by supervisor.
• B. If the operation could trigger electrical circuits, or if tools/robots pose a risk to energised equipment.
• C. Never.
• D. Only during night.

Answer: (B)

Temporary de-energization is used whenever there is a real risk that the task could energize circuits or that tools, robots, or other equipment could interact with energized systems in a way that causes harm or unintended operation. By removing power and verifying zero energy, you create a safe boundary so a person isn’t exposed to shock or an arc flash, and so devices or downstream systems aren’t unintentionally energized or triggered during the operation. This approach applies when a task could trigger electrical circuits or when the tooling or robotics involved could pose a risk to energized equipment. Relying solely on supervisor approval or performing the step only at night doesn’t address the actual hazard, and saying never would ignore that some tasks inherently create energy-related risks.
