Vic, Consider installing a low oxygen alarm; www.enmet.com probably has what you need. We have a similar situation using plumbed in CO2. As far as regulatory backup to justify this very minor expense, OSHA's General Duty Clause 29 CFR 654, 5(a)1 likely covers that - especially since you've already identified the specific hazard.

The building will be multi-use, with offices in one portion and maintenance facilities adjoining. There will be six utility stations in the building with nitrogen piped to each utility station along with other utilities. The nitrogen supply line at each utility station will be a one-inch diameter line with a ball valve, a check valve, and a globe valve. Could you please alert us to any applicable codes and standards specificall y regarding any risks associated nitrogen asphyxiation. Thanks and best regards, Vic Victor H. Edwards, Ph. D., P.
