i'm familiar with the destructive power and unpredictable nature of hydrogen detonations, yes ;)

but that's what happens when you don't vent the hydrogen to the atmosphere

Yes, but improperly venting the hydrogen is "not venting hydrogen" but looks like venting the hydrogen unless closely inspected.

you can do it in ways that are really obvious, though only to someone who knows the order of magnitude of hydrogen that could be produced
