🔍 Key Concepts

• Purpose of an overflow tank in a fuel oil system • Immediate actions required when a high-level alarm sounds during bunkering or fuel transfer • Risks of continuing fuel transfer when any high-level alarm is activated

💭 Think About

• What is the main safety concern when an overflow tank reaches a high level—spillage, pressure, or flow rate? • In an emergency or abnormal condition, which action should come first: stopping the source, slowing it down, or adjusting valves downstream? • Which option most directly and immediately prevents more fuel from entering the system without needing further adjustment?

✅ Before You Answer

• Identify which choice immediately stops additional fuel from entering the tanks. • Consider which actions (valve adjustments, rate changes) might still allow fuel to keep flowing after the alarm. • Ask: if you delay by only a few seconds, which choice best prevents a spill or overflow incident?
