Consider purchasing a hydrogen gas generator, move away from cylinders and storing the gas. An entire department could pitch in for the purchase and share the device. Yes, they are expensive, but not nearly as expensive as rebuilding
a blown up burnt out lab, or worse the medical costs of a seriously injured person.

I’d just buy a lecture-size bottle of H2 and be done with it.

Does anyone have recommendations on how to *safely* fill a balloon with hydrogen? The hydrogen tank in this scenario is in an open lab, and the hydrogen filled balloon is for a hydrogenation reaction. The gas tank is located close enough
to a fume hood that piping the hydrogen into the fume hood might be feasible. Wondering what other people’s experiences have been with this.
