How is an inert gas system designed to reduce the possibility of tank explosions?
AI Explanation
The correct answer is C) by reducing the oxygen concentration below levels necessary for combustion.
An inert gas system is designed to reduce the possibility of tank explosions by lowering the oxygen concentration in the cargo tanks to a level where combustion cannot occur, typically below 8% oxygen by volume. This effectively creates an inert atmosphere that prevents the ignition of flammable vapors, even if an ignition source is present. The other options are incorrect because they do not directly address the primary function of an inert gas system, which is to maintain a safe, non-flammable atmosphere in the cargo tanks.
