Jefferson Laboratory, Newport News, VA, has a really nice, useable
publication on the internet about oxygen deficiency hazards when working
with inert gases, especially N2.

Subject: [DCHAS-L] NMR Ventilation ?
Hello Everyone,
I am looking for advice for installation for a new 400 MHz NMR. Our faculty
and EHS people (from another campus) cannot seem to agree about the
ventilation for cryogen safety. Does anyone have any ideas what best
practices are for a 400 MHz? The EHS people are not agreeing with Bruker's
recommendations.
Is emergency exhaust or a quench pipe more reasonable for a small space on a
400 MHz system? I am worried that having the quench pipe for the He would
not be sufficient to protect against any N2 accumulations. Is there a "best
practice" for a NMR in its own small space (approx. 1500 cu ft)?
I appreciate any advice that can be provided.
Thank you,
Monique Wilhelm
