Who must determine if equipment can be safely energized after a circuit is de-energized?

A qualified person is specifically trained and knowledgeable about the electrical systems and safety protocols, which allows them to make informed judgments regarding the safety of energizing equipment. This expertise encompasses an understanding of the equipment involved, the potential hazards that may be present, and the necessary precautions that need to be taken to ensure safety.

The determination of whether equipment can be safely energized after being de-energized requires a comprehensive assessment of various factors, including lockout/tagout procedures, verification that all personnel are at a safe distance, and that there are no remaining hazards from electrical energy or stored energy in the equipment. A qualified person's training includes these crucial assessment skills, ensuring that safety is prioritized in the workplace.

In contrast, the other roles mentioned, such as any worker, a supervisor, or a safety officer, may not possess the specific technical knowledge or qualifications required to evaluate the condition of demanding electrical equipment effectively. Thus, the responsibility for such determinations rightly falls on those with appropriate qualifications and training.
