Past lab chemist always pressure checked and purged the balloon with nitrogen or another gas compatible with the chemistry. The riskier the reaction, the more I would suggest a better set up.

Hi all,
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.
Thanks,
Laura
