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

Enclosed spaces like cargo pump rooms often contain toxic and oxygen-deficient atmospheres. Standard emergency rescue protocols dictate that entry personnel must use positive-pressure self-contained breathing apparatus and secured lifelines to protect against sudden asphyxiation or hazardous vapor exposure during rescue operations.
