Remember the Hindenburgh. Helium has 1/4 the lifting power of hydrogen, but is much inherently safer.Can't be used inmany lab reactions, however.

I'm aware of many situations where research involving hydrogen gas is being conducted as part of cutting edge science and I wonder if the research planners understand how much engineering is involved in developed a safe and compliant system to support this use? It seems to me that much of this work is beyond the scope of the OSHA Lab Standard and that funding agencies should inquire about how oversight of the use of flammable gasses will be maintained.

Are there signals in a protocol (such as an amount used) that could be used to identify work that raises this concern?
