🔍 Key Concepts

• Person-in-charge (PIC) responsibilities during fuel transfer operations • Safety risks associated with topping off and potential overflows • Environmental regulations about discharge of oil or oily waste overboard

💭 Think About

• Which option describes a task where a mistake could immediately cause a spill, fire, or serious casualty if not closely supervised? • Which tasks are typically done once before or after the transfer, and which one is critical at the moment tanks are almost full? • Think about when the person-in-charge must be physically present and paying close attention rather than just delegating or checking paperwork.

✅ Before You Answer

• Identify which operation is most directly tied to overflow/spill risk at the end of loading • Recall that deliberate discharge of oil or slops overboard is strictly regulated and generally prohibited, not something to be supervised as a normal operation • Distinguish between administrative tasks (like posting documents, periodic checks) and the specific high‑risk step that must be personally supervised
