Tank vent flame screens must be maintained in good condition and properly fitted in the opening they protect in order to __________.

🔍 Key Concepts

• Purpose of a flame screen in a tank vent on a vessel carrying flammable liquids or vapors • How flame propagation through a vent can be affected by a mesh or screen • Difference between vapor movement and flame/heat transfer

💭 Think About

• What happens if an external ignition source (spark or flame) contacts vapors at the vent? What is the flame screen supposed to stop or control in that situation? • Think about whether a vent must stay open or closed to keep the tank safe from overpressure or vacuum while loading/discharging cargo or during heating. • Which option best matches the idea of safety against ignition rather than just containing or releasing vapors?

✅ Before You Answer

• Identify which choices talk about vapors moving versus flame or heat moving. • Ask: does a flame screen’s mesh mainly stop vapors from moving, or does it mainly stop a flame from traveling into or out of the tank? • Make sure the option you choose is concerned with ignition and fire safety, not simply with ventilation or vapor retention.
