    Can an existing standard 10 x 10 manifold inside the building serve as the reserve for a new micro-bulk system that would be installed outside of the building? Or would this be considered an in-building emergency reserve?

    Great test question.

    Let's review 3 points here.

    NOTE: Micro-Bulk first showed up in the 2015 Edition of NFPA 99.

    Please understand your statement was based,

    on the Micro-Bulk System being outdoors.


    Your In-Building Reserve can not be a substitute for the bulk gas reserve supply.


    Your In-Building Reserve can be a substitute for the EOSC.

    (i.e. you have to have an eosc or a in-building reserve)

    Now the last part #3, is clear as mud 


    (Micro-Bulk) The primary & secondary supply shall be in the same enclosure.


    (Micro-Bulk) With a reserve supply, shall be permitted in the same enclosure, or per per all the requirement of & CGA M-1.

    You have to read the whole section # ( 8 times )

    To this end - In my opinion. The Micro Bulk Vessel and the Reserve Supply shall be in the same location.
