🔍 Key Concepts

• Immediate safety and pollution control responsibilities during fueling operations • Order of priority: stop the source vs. report the problem • Basic principles of the U.S. oil pollution regulations (33 CFR 155 & 151): control, contain, then report

💭 Think About

• Ask yourself: If oil is already on the water, what action most directly prevents more pollution in the next few seconds? • Which choice best helps you confirm whether there is an ongoing discharge from your vessel before or while you start notifying others? • In a real-world spill, what must happen first: verify/control the source, or complete a full chain of notifications?

✅ Before You Answer

• Identify which option deals with immediate control or confirmation of the source rather than just informing someone else • Consider which action you personally can take right away, without waiting on another person’s decision • Think about pollution response sequence: stop/confirm the source, then notify and document—see 33 CFR requirements for oil discharges
