Dear Christopher,


It looks like at Ithaca, you fall under International Fire Code 2015 which was adopted by New York State.  At Princeton, we fall under International Fire Code as well (with some New Jersey adaptations).  I imagine they’re closely the same. 


The helium and CO2,and compressed air are the easiest to store because they don’t need to be segregated from any other compressed gas hazard as they are considered inert. 


The O2 cylinder must be separated from your flammables:  CO, H2, CH4, and liquefied propane.  In IFC 2006 NJ Edition (I don’t want to pay for a pdf of IFC 2015 as adopted by New York) 2703.9.8 Separation of incompatible materials (when stored material containers have capacity of more than 2kg and 2L) must be accomplished by :


·        Minimum of 20 feet

·        Non-combustible partition extended minimum of 18 inches above and to the sides of stored material

·        Storing in gas cabinets or exhausted enclosures. 


All of these gases, aside from having to be segregated from each other by hazard class, will have maximum allowable quantity (MAQ) limits based on the type of occupancy and rating of the lab.  Gas cabinets and automatic sprinklers increase your MAQ’s.    Please contact me directly if you have any questions about ways to design this storage to get the most out of it. 



Best Regards,

Whats the best way to store and separate the following gases in a laboratory within the regulations.


We have a potential gas storage room (that would need to be converted), a single cylinder vented cabinet (but could purchase more), and the usual lab wall storage.


O2,  CO, CO2, H2, He, CH4, propane, and compressed air.
