During oil transfer operations, who would be responsible to guarantee that the posted transfer procedures are being followed?

Correct Answer: Option C — The designated person in charge

Under 33 CFR 155.700, the designated Person-in-Charge (PIC) holds the ultimate responsibility for the safe conduct of oil transfer operations. The PIC must ensure that the transfer procedures are followed, safety equipment is ready, and all personnel involved are aware of their specific duties and emergency protocols.
