Q

The device used for preventing the passage of flames into enclosed spaces is called a __________.

🔍 Key Concepts

• Flame propagation through vents or piping on tanks or enclosed spaces • The difference between a device that stops flame versus a valve that relieves pressure • Typical equipment fitted on fuel tank vents and cargo tank vents to prevent fire from entering the tank

💭 Think About

• Which of these options is specifically designed to allow gas to pass but stop flame from passing through an opening or vent? • Which options are mainly used to relieve excess pressure rather than to block flame travel? • Think about what is commonly installed on fuel tank vent lines on small boats and tank vessels to prevent external fires from entering the tank.

✅ Before You Answer

• Identify which device’s primary function is flame blocking, not pressure relief. • Eliminate any options that are mainly used for overpressure protection (e.g., on boilers or pressure vessels). • Consider what the term is in USCG and marine safety literature for equipment on tank vents that stops flame fronts from entering.
