In port, who is in charge of the tag-out log?

• A. Engineering Duty Officer (EDO)
• B. Commanding Officer (CO)
• C. Safety Officer (SO)
• D. Maintenance Supervisor (MS)

Answer: (A)

The tag-out log in port is under the engineering authority—the Engineering Duty Officer handles it. This log records every energy-control action, including who applied the tag, what equipment is involved, when it was tagged, and why. The EDO has overall responsibility for the ship’s engineering plant and the integrity of the energy-control program, so they ensure tags are applied correctly, kept current, and removed only once the work is completed and the equipment is safe to return to service. While the Commanding Officer oversees overall safety and readiness, and the Safety Officer or Maintenance Supervisor administer day-to-day safety or maintenance tasks, the formal control and documentation of tag-outs rests with the EDO.
