Hydrogen requires oxygen from the atmosphere to explode.

2H2 + O2  =>  2H2O

It also needs a spark or flame to get it started.
If you pump nitrogen in all the oxygen is displaced, and the reaction cannot occur.

Nitrogen is a safe bet because it is inert and abundant in nature.
However, it is lighter than oxygen, so they would be better off with something like halo-methane (if they had more time and money).
