    Do manifold rooms meet the requirements of a "Confined Space" (OSHA's 29 CFR 1910.146)?


    https://www.osha.gov/Publications/osha3138.pdf


    If so, is this reasoning for the increase in the use of oxygen depletion monitors in these areas?


    Is there anything in NFPA 99 concerning monitoring the monitoring of oxygen concentrations in these areas, I have looked but was unable to find anything in NFPA 99.

    These are common in lab and industrial settings.  I typically recommend installing these as a best demonstrated practice--an inexpensive safety practice--for any interior manifold room with non-breathable gases, with an external strobe mounted above the entry if the alarm is mounted remotely.

     

    We've installed many of the RKI Instruments Beacon 110 (https://www.rkiinstruments.com/product/beacon-110/?msclkid=749218a1738e1e1afd6045e9c222f079&utm_source=bing&utm_medium=cpc&utm_campaign=Branding%20Products%20Search&utm_term=beacon%20110%20gas%20monitor&utm_content=beacon%20110%20gas%20monitor) on the cruise ships we do, which often have a central oxygen manifold in a small, watertight compartment.  So this purpose is more to monitor for a catastrophic leak that might elevate oxygen levels and increase the fire/explosion hazard. 

     

    They're easy to test and maintain, and we typically recommend replacing the sensors annually.

    Luke, thanks for the link. To all, when you use a strobe or alarm to warn of a possible hazard (oxygen deficient or enriched atmosphere) you should post a sign telling personnel what to do, such as do not enter the room. I have seen several where alarms signals exist but people do not know what they mean when they are active.

     They specialize in gas monitors and we have been using them for compliance for oxygen generator rooms and labs.
