Energized work is generally prohibited. Such work is permitted under which of the following conditions?

• A. I, II, and III
• B. I and II only
• C. II and III
• D. I only

Answer: (A)

Energized work is allowed only when you cannot safely de-energize the equipment and a controlled plan with protections is in place. In practice, this means three things must be true: the task cannot be performed in a de-energized state; there is formal authorization plus a documented plan (an energized work permit) that identifies hazards, scope, and controls; and the work is carried out with appropriate protective measures by a qualified person (PPE, insulating tools, barriers/shields, and safe-work procedures). When all of these conditions are met, energized work may proceed; if any one is missing, it should not be performed energized.
