🔍 Key Concepts

• overflow and venting requirements for fuel/settling tanks • proper tank sounding and monitoring during fuel transfer • environmental rules that limit when/where you can use chemical dispersants

💭 Think About

• During a fuel transfer, what is the safest way to avoid overfilling a tank: relying on overflow lines, blocking vents, or actively monitoring levels? • How should the transfer rate be managed as the tank gets closer to full, and why? • Which option, if chosen, might actually increase the risk of overpressure or uncontrolled spills?

✅ Before You Answer

• Make sure the option you choose involves actively checking tank level during transfer • Eliminate any option that would block or disable tank vents or overflows • Be cautious of any option that assumes it is acceptable to overflow fuel tanks by design as part of normal operations
