Question 1 of 27070

Q

Coast Guard Regulations (46 CFR) require that quick-closing valves on a fuel oil service system should be installed as close as is practicable to the __________.

🔍 Key Concepts

• 46 CFR requirements for fuel oil service systems and emergency shutoff arrangements • Purpose of quick-closing valves in limiting fuel in case of fire or leakage • Location of fuel oil tanks vs. downstream components like pumps, heaters, and headers

💭 Think About

• Ask yourself: In an engine room fire, where is the best place to stop the flow of fuel entering the system? Upstream at the source, or farther downstream? • Which component, if isolated, will cut off fuel to the entire service system, not just one piece of equipment like a pump or heater? • Think about which item in the choices is the primary fuel source feeding the rest of the system rather than just a user or accessory.

✅ Before You Answer

• Identify which choice represents the fuel source/storage rather than a consumer (like a boiler) or a treating device (like a heater). • Confirm in 46 CFR that quick-closing valves are intended to be located as close as practicable to the tank outlets or source of fuel supply. • Check which location, if closed, would most effectively limit the amount of fuel available to a fire throughout the system.
