[labnetwork] Nitrous Oxide Gas Monitoring Survey

Tue Jul 30 11:11:16 EDT 2024

Hi Dan,

I agree with Deon that it's best to check with your local Authority Holding Jurisdiction. CSI has worked with facilities that has required full cabinets since it's an oxidizer, as well as facilities that are comfortable using semi-automated panels with no enclosure. It is not considered corrosive, toxic, or flammable which is why there is diversity in how it is stored.

It is a liquified gas, so however you store it, you'll probably want scales to monitor weight as a more accurate usage measurement instead of relying on a pressure transducer. If you have any questions about cylinder cabinets or panels, please feel free to reach out.

Thank you,

I would research codes relating to your local and state. Research the H-5, SEMI and Cfats regulations. Aking for support outside of your locality may create regulatory issues.

Lab Network,

Our IR sensor for N2O monitoring has recently died, and there are questions being raised on if it is needed or not. If your facility has nitrous oxide in it, I would appreciate if you can share the answers to these two questions:

  1.  How do you store / secure the N2O (gas cabinet, gas bunker, neither, etc.)?
  2.  Do you have any gas monitoring for it?

Any other code or security / abuse insights anyone can offer would also be appreciated. Thanks.

Dan
