🔍 Key Concepts

• 46 CFR requirements for fuel oil service systems and fire safety • How fuel oil service pumps are controlled in emergencies • Which design features are intended to reduce fire risk, not increase it

💭 Think About

• Which option most clearly helps you control or stop the fuel supply quickly during a fire? • Are any of the options suggesting a practice that might actually increase fire hazard rather than reduce it? • Think about what the Coast Guard focuses on more: efficiency and convenience, or fire protection and emergency shutdown in fuel systems?

✅ Before You Answer

• Verify in 46 CFR Subchapter F (Marine Engineering) how fuel oil service pumps must be arranged for emergency shutdown. • Check which arrangements of piping and tanks would spread fire or heat versus those that limit or isolate it. • Confirm that the regulation emphasizes remote stopping or isolation of fuel in case of fire, rather than using boiler heat for efficiency.
