I believe that the crawl space does meet the intent as long as it meets the requirements on that section. I am going by memory but I believe that there can't be any storage or fuel fired equipment and maybe a couple of others. One key to this is that I believe that the space above then has to use a 3,000 ft calc area. I think the 2013 is going to minimum of 8 heads (AFSA convention) in lieu of the 3,000 but for now it is 3,000.

(CSFD) Sent: Wednesday, October 24, 2012 11:08 AM To: '[email protected]' Subject: FW: Sprinklers in crawl spaces Anyone have any insight on this? We have an old commercial building that was previously not sprinkled that is going through a change in occupancy classification and is now retrofitting sprinklers. This building has a very large crawl space with masonry walls and a dirt floor. The floor assembly is combustible solid wood joist with a wood sub-floor. In looking in NFPA 13 (2010 Edition), there are two possible options in defining this space and determining if sprinklers are required. The first section is 8.15.1 for concealed spaces - in reviewing all the possible scenarios in this section I don't see where sprinklers can be omitted. The second section is 8.15.6 for Spaces under ground floors, exterior docks, and platforms. The question I have for the group is does "spaces under ground floors" meet the intent of a crawl space? If not how would you define a space under a ground floor, and how are this different from a crawl space. If section 8.15.6 is appropriate then it does allow for the omission of sp rinklers. I'd really like to know how other have addressed this situation.
