Most jurisdictions that I have worked in do not want the 1 1/2" hose installed, and the building codes (IBC) do not require hoses. I was wondering why this is a class III standpipe to begin with.

Most FD do not use 1½" hoses to fight fires, they are for clean-up and untrained persons. If there aren't any hoses then why provide the 1½" reducers? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Paul Pinigis Sent: Tuesday, January 30, 2007 2:02 PM To: [email protected] Subject: RE: NFPA #14 and pressures One thing that does not make sense....where are these untrained people going to get 1 1/2" hose?

The 1½" hose station is available for untrained persons thus the pressure limit. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dave Thompson Sent: Tuesday, January 30, 2007 12:11 PM To: [email protected] Subject: NFPA #14 and pressures NFPA #14 states that when the static pressure at a hose connection exceeds 175 psi, a pressure regulating device shall be provided to limit the pressure to 100 psi for 1 ½" hose connections and to 175 psi for all other hose connections. What if the standpipe is a Class III utilizing the fully sprinklered building exception allowing 2 ½" hose valves with 1 ½" reducers, caps and chains? Does the pressure need to be limited to 100 psi or 175 psi? Dave David K. Thompson Vice President Allstate Fire Sprinkler, Inc. P.O.
