If the hydrogen gas stored inside a lab is below MAQ thrash hold, you can have the cylinder nearby GC. Storing cylinder remote from GC will require additional safety measures (pipe maintenance etc.). Hope this is helpful.
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.
