NFPA 99 Med Gas Storage

NFPA 99 med gas storage allows 300 cu ft and less to be stored outside enclosures, with certain parameters. I’m hearing George Mills is saying that there can be multiple store rooms with 300 cu ft.

I get the 300 to 3,000 cu. ft. requirements for enclosures, but I’ve taken it to be that after you use the allowance for up to 300 cu ft per 22,500 sq ft, that anything over that would have to be in an enclosure meeting the definition of 9.4.2 (NFPA 99-2002), whereas it has to be separated by 5 ft from storage (sprinklered), etc or be in a rated cabinet. Question is, within one 22,500 sq ft area, can you have any number of storage areas that you want of 300 cu ft or less, so long as they’re in rooms, ie clean utility rooms, regardless of sprinklering, separation, etc. NFPA 99 doesn’t come out and say that, so I’ve never assumed it.
