When entering the pump room of a tank vessel to rescue an unconscious person, which items of the equipment listed are you required to be using?

Correct Answer: Option D — Self-contained breathing apparatus and lifelines

Per 46 CFR, entering a hazardous space like a pump room requires a self-contained breathing apparatus (SCBA) to protect against toxic vapors or oxygen deficiency. A lifeline is mandatory to ensure the rescuer can be retrieved if they become incapacitated, maintaining safety during emergency entry operations.
