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 and http://w

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.
