Location of Class I standpipe hose connections per the Building Code (I'm quoting IBC 2009 with CA amendments): 1. In every required stairway, a hose connection shall be provided for each floor level above or below grade.
The purpose of a standpipe system is to alleviate the need for firefighters to bring charged hose into a building and have to go up or down with it to a fire floor. Obvious impediments are raw weight and kinking. The building codes have exempted the apparatus access floor from standpipe hose connections for numerous cycles because hose can be brought directly into the building from apparatus for operations on that level. This doesn't address the travel distance issue raised by your AHJ, but the building isn't required to have standpipes in the first place and the first floor would be excepted if it did. My opinion only, and not to be considered a formal or informal interpretation of the NFPA 14 standard.

A small 2 story area the rest is all one story. There is a running track on a mezzanine that circles the gym that is at 32 ft. high but it is open to the gym. This is an addition to a building that is sprinklered but without standpipes. The new addition meets all the exiting and egress requirements so that is not an issue.

How many stories is the building, and on what floor is this condition? Steve Leyton -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Tuesday, January 29, 2013 7:16 AM To: [email protected] Subject: Fire Marshal requirement? This from a Fire Marshal for a large University in AZ. We were having trouble locating hose valves in the one story area of the building. There are only two stairs in the building and they are more than 200 ft. from parts of the gymnasium. We reviewed the code and offered a credit to delete the standpipe system because we didn't think it was required. This the response from the FM. He wants all interior points to be with 150 feet from where they park a fire truck. "If you send a too scale plan from where fire trucks will be at all points of entry to the building and can show that nothing is more than 150' I will entertain the suggestion of no standpipes. I have seen everything that ****** has been shown and it is not represented well. This includes the existing building since the existing building had adequate coverage and did not need a standpipe before the add-on. Now that there is an add-on where there is no access at the center point it affects both the new and old and we need assurance with a too scale drawing from fire truck to all areas of all floors. Discussing it does not solve anything until you can also prove it on paper too scale "as the hose lays and not the crow flys." I have difficulty finding a way to talk to someone like this.
