Okay, seriously. A platform is a raised surface, that may be slab-on-grade, or framed up from a structural floor assembly. Generally, the ceiling over it is the same one that is above the seating/assembly areas of the larger room in which the platform is located.
A stage has a proscenium that separates the back of house space from the seating/assembly space. Also generally, it has no suspended ceiling or a much higher ceiling over it, known in the theater biz as "bag and flag" space. Curtains, lighting, set pieces, etc., etc. are potentially stored/suspended in this space and it creates a unique and elevated fire load. Hence, stages are protected for Ordinary Hazard and assembly areas (and platforms) for Light. There is also a requirement that either the stage curtain be fire-rated, or that a "fire-curtain" assembly be provided, or that a water curtain or deluge system be provided at the proscenium to protect the separation between a legitimate "stage" and the A-group.

I'm looking at a charter school auditorium/gym. The stage is a platform elevated 1'-6" above the concrete slab. There is ACT ceiling at 20 ft and a 12ft x 40ft opening to the auditorium. There doesn't appear to be room for drop scenery like in a professional theatre stage. Class III standpipes and OH group II seem excessive for this application. I fear what might happen if a 90 lb drama student decides to mess with 1½" fire hose with 100psi raging behind it. I've found some info in NFPA 101 but I still confused on the stage and platform definitions. Any help will be greatly appreciated Thanks, Randy Knutson Shilo Automatic Sprinkler, Inc. P.S. Bob I'm not ignoring you. _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field)
