I=E2=80=99ve not had much success going the fire safet y route, so am trying the chemical/lab safety listservs for help. Ple ase 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=E2=80=99t 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=E2=80=99 x 4=E2=80=99 x 4=E2=80=99. The tent appears to be made of a clear plast ic material. I do not as yet know if it is static-resistant.
The other is a chemistry lab where the hydrogen will b e used to consume residual oxygen in an anaerobic chamber. The approx imately 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 us ed in the lab. I doubt there are safer substitutes in these cases, bu t if anyone knows of one, can you please share them?
Can anyone point me to specific safety guidelines I ca n share with these researchers?
Thanks in advance.
