🔍 Key Concepts

• 46 CFR Subchapter M requirements for towing vessel fuel systems • Purpose of fuel shut-off arrangements in a fire situation • Location from which the fuel supply should be controlled during an emergency

💭 Think About

• If there is a fire in the machinery space, which device and location would let you stop fuel flow without entering the fire space? • Which choice describes a valve type and location that is specifically aimed at emergency remote control, not just normal operation or draining? • Think about which type of valve is most commonly required by regulations for quick, positive shutoff of fuel to engines.

✅ Before You Answer

• Verify in 46 CFR that the regulation talks about a fuel shutoff that can be operated from a safe location • Check which options are about controlling fuel flow versus simply draining or venting fuel • Confirm which valve type is designed for remote emergency operation at the tank, not just manually turning a handle nearby
