Q

Which of the devices listed is designed to prevent flames from entering a fuel tank through tank vents?

🔍 Key Concepts

💭 Think About

• Which of these devices would logically be installed at the open end of a vent where an external flame could appear? • Which option is more commonly associated with engine exhaust systems rather than fuel tank vents? • Think about which device is specifically meant to stop flame from traveling through an opening, not just to stop liquid flow or reduce vapors.

✅ Before You Answer

• Identify which device is normally found on gasoline fuel tank vent outlets in USCG illustrations and textbooks • Eliminate the device primarily used on engine exhaust manifolds (not vents) • Focus on the option whose purpose is to stop flame from entering or passing through a vent opening.
