How does an inert gas system on a tanker function to prevent explosions in cargo tanks?
AI Explanation
The correct answer is D) Inert gas dilutes the flammable vapor and air concentrations to keep them below the lower explosive limit.
Inert gas systems on tankers function to prevent explosions in cargo tanks by reducing the oxygen content and diluting any flammable vapors present. By maintaining an inert atmosphere with less than 8% oxygen, the mixture of vapors and air is kept below the lower explosive limit, preventing the possibility of an explosion. The other options are incorrect because they do not accurately describe the primary purpose and mechanism of an inert gas system on a tanker.
