If ventilation is ongoing then most leaks would be well below the level
where the output gas was flammable.

A "Davies lamp" arrangement could be employed where a flame inside a mesh
barrier allowed flammable gas mixtures to enter and be combusted but did
not allow flame to propagate beyond the enclosed space.
