When is equipment considered de-energized?

Equipment is considered de-energized when it has been safely disconnected from its energy source, ensuring that the energy cannot inadvertently re-energize the system during maintenance or inspections. The correct understanding of this concept arises in scenarios involving safety protocols.

In this context, "de-energized" refers specifically to the processes that ensure the equipment has been properly isolated from any energy source. This includes not just the action of turning off the power, but also implementing safety measures, such as lockout/tagout procedures, which are crucial for protecting workers.

The processes of Inspection, Verification, and Validation (IVV) in the maintenance routine serve to confirm that the safety measures—such as ensuring lockout devices are in place and functioning—are indeed enacted. Therefore, equipment is considered de-energized once it has gone through this verification process thoroughly, proving it is not only turned off but also secured against accidental re-energization.

While maintenance typically begins once items are confirmed to be de-energized, the condition of being locked out underscores the importance of the safety protocols in place. Equipment can’t simply be deemed de-energized without these checks, which creates the environment for safe maintenance work. In summary, the notion of de-
