Question 1531Deck General70% to pass
Which of the following choices does not depict the tank inerting process on a tank vessel?
AI Explanation
The correct answer is D) the introduction of oxygen into a gas free tank prior to entry.
The tank inerting process is designed to reduce the oxygen content in a tank to below 8% by volume, in order to create a safe atmosphere for entry or cargo operations. Introducing oxygen into a gas-free tank would have the opposite effect, increasing the oxygen content and making the tank unsafe for entry. The other options (A, B, and C) correctly describe the tank inerting process of reducing oxygen through the introduction of inert or nitrogen gas.
