Mikeit takes only a small percentage of an inert gas to render an explosive atmosphere "safe" regardless of what the gas is. It comes down to energy of explosion and energy to heat up inert gases to the point where the combustion is self containing. If you blow up the main fuel tank, inert gas protection is not going to mean much, and if you just want to protect the air space in the thank. then a little bit of exhaust gas is going to be hard to beat.
