Q

A device for preventing sparks or flames from entering a tank, while permitting the free passage of gases, is called a __________.

🔍 Key Concepts

• Inert gas systems and tank safety on tankers • Purpose of flame arresting devices on vents and openings • Difference between devices that control pressure and those that stop flame propagation

💭 Think About

• Which option’s primary job is to stop a flame from traveling into a tank, while still letting gases flow freely? • Look at each choice: is it mainly for measuring, for controlling pressure, for corrosion protection, or for blocking flame? • On cargo tank vent lines, what specific safety fitting is installed to prevent an external ignition source from flashing back into the tank?

✅ Before You Answer

• Identify which device is specifically designed as a barrier to flame/sparks, not for measuring gas or relieving pressure • Eliminate any option whose main function is corrosion protection or detection/measurement • Confirm that the remaining device is normally fitted in tank vents or openings to let gases pass but block flame fronts
