Two resources for gas fittings and compatible tubing material are Scott’s Specialty Gas or Airgas. Check out their Technical information online or speak to a representative from the company that will supply the H2 to the lab. Contacting these suppliers will probably get your specific questions answered quickly.
A second resource is the Hydrogen Association at http://www.hydrogenassociati on.org/ and http://w ww.hydrogenandfuelcellsafety.info/resources.asp
Note there are links to best practices, lab safety, fittings and tubing. You’ll learn more about hydrogen gas safety than you ever thought to ask.

Subject: [DCHAS-L] H2 Safety Requirements or Guidelines
I’ve not had much success going the fire safety route, so am trying the chemical/lab safety listservs for help. Please forgive the cross-posting.
We have 2 researchers who use or plan to use hydrogen gas in their labs.
One is a biology lab and I don’t yet know much about why and how the hydrogen is used, except that it appears to be being plumbed into a tabletop “tent” approximately 4’ x 4’ x 4’. The tent appears to be made of a clear plastic material. I do not as yet know if it is static-resistant.
The other is a chemistry lab where the hydrogen will be used to consume residual oxygen in an anaerobic chamber. The approximately 1-lb tank will be secured to the bench and the researcher plans to plumb it himself with copper line.
Naturally I have some concerns about hydrogen being used in the lab. I doubt there are safer substitutes in these cases, but if anyone knows of one, can you please share them?
Can anyone point me to specific safety guidelines I can share with these researchers?
Thanks in advance.
