Check the exception - in a sprinklered building a "Class III" isn't really. The tendency in code development has been to reassess whether it's in everyone's interest (fire service, building owners, tenants and guests) to keep an attractive nuisance like a hose cabinet in the code. Current life safety and egress training practices are to encourage everyone to leave the building when an alarm sounds and that's tough enough right there. We don't want Wannabe Superhero Guy rushing toward the fire with a hose in his hand that will likely knock him (or her) on their butt. In a sprinklered building the intent is to provide the reducer so that small hose can be connected as easily as a larger one - it's largely symbolic you could say. But the hose is furnished by responders (these days they're worn as backpacks).

I was wondering why this is a class III standpipe to begin with. Paul J. Pinigis, P.E.

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.
