Janet,
If done correctly, plumbed system will not add to the risk of the project. By “done correctly” I mean that: (1)the gas piping is double-walled stainless, (2) properly designed and executed hydrogen monitoring in the storage and use areas and (3) cylinders are stored flammable gas storage cabinets.
The cylinders next to the instrument should be in flammable gas storage cabinets now and you should be drawing the hydrogen from the cabinet, not a bare tank. Likewise, you should be monitoring near the ceiling and in the corners now as well.

Subject: [DCHAS-L] plumbing H2 from remote location
To All:
We need to use H2 gas for FID-GC. Our campus EH&S officer wants us to plumb H2 gas from a cylinder placed at some remote location (as yet unknown to me, but I've heard both: a) from the hallway and b) from outside the building) to our instrument lab. We do not see why we cannot use the H2 cylinder in the instrument lab, next to the instrument, as we have been doing. Increasing the distance between the H2 cylinder and the instrument seems like it would increase the safety risk.
I'd appreciate hearing your thoughts/comments/experience in handling H2 safely in your labs.
