A device fitted over the discharge opening on a relief valve consisting of one or two woven wire fabrics is called a flame __________.

🔍 Key Concepts

• Flame screens and their purpose on tank vessels • How woven wire fabric is used to stop flame propagation in vapors • Where relief valves and vent outlets are fitted on cargo or fuel tanks

💭 Think About

• Ask yourself: which term is commonly used in tanker safety to describe a woven wire device that stops a flame from passing through a vent or valve opening? • Think about the function: is this device meant to block flow, filter particles, or prevent flame from traveling back into a tank through a relief valve? • Which of the options is an actual standard safety term you’ve seen in firefighting or tank-venting diagrams?

✅ Before You Answer

• Verify which option is actually paired with the word "flame" in marine safety texts (for example, on cargo tank vents). • Make sure the choice matches a device made of woven wire fabric, not a solid plug or ordinary filter element. • Confirm that the device’s primary purpose is preventing flame from passing through the relief valve outlet, not restricting flow or stopping it completely.
