Would one option be just to consider it a floor opening still and provide a water curtain around it?

Barring a correction from a section that actually says that if you are talking about trade-ups the IBC says you can lower 1 hour requirements to 0. It does not say 0 will achieve 1 hour when sprinklered. Especially when in a LH you only need 30 minutes of water. Yes, yes there are very few buildings with rating requirements and no OH. But I have seen a few gov't buildings where the LH was the driving force on water because no room design method and you can pack a lot of sprinkler in the bathroom/locker/hallway cluster. Last one was 27 or 28 heads in a 3,000 sq.ft. LH design. Again, I don't know everything show me your cards if you got them.

(increased travel dist. is still ok). _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum
