I agree with Pete. What is the argument against this? There would still be sprinklers in the closets, they just wouldn’t be included in the calc, right?

The closets are less than 55 Sq Ft. Since the closet is separated most likely with drywall construction and with a 1500 SQ FT design area, I am not at all concerned with a fire starting in a closet and growing to the point of overwhelming a system designed to 1500 SQ FT. I would eliminate the sprinklers based on 23.4.4.7.2. Just my opinion and not that of the NFPA or the SSD Committee.

That’s … not a sprinkler-friendly design, is it? Architects and developers always say, “We don’t need a fire protection consultant, we leave that to the installing contractor.” How are these “closets” built? Are they lockers (i.e. fixtures) or are they framed walls? I’m still not seeing how you can leave them out but looking for an angle here … Steve From: Sprinklerforum [mailto:[email protected]] On Behalf Of [email protected]<mailto:[email protected]> Sent: Friday, September 21, 2018 1:43 PM To: [email protected]<mailto:[email protected]> Subject: Re:ELIMINATION OF SPRINKLERS IN CLOSETS FOR HYDRAULIC CALCULATIONS Did you read the original email. 10sqft.

Sent from my Huawei Mobile -------- Original Message -------- Subject: RE: ELIMINATION OF SPRINKLERS IN CLOSETS FOR HYDRAULIC CALCULATIONS From: Steve Leyton To: [email protected]<mailto:[email protected]> CC: The math doesn’t add up – how would eliminating sprinklers for four 10’x10’ closets save 14 sprinklers in the DA? Notwithstanding those metrics, these are not small clothes closets, they are repositories for people’s “stuff”. You have a prevailing ordinary hazard with accessory miscellaneous storage for lack of a better classification. I respectfully disagree that eliminating sprinklers is consistent with the intent of the reference section. 100 sq. ft. packed with camping gear and seasonal toys is a very different condition from an interior closet that might only be 15-25 sq. ft in area.

There are 4 units which each have an open parking garage under the 2nd floor. Along the back wall are 4 (10sqft ) closets. The engineer is asking for a dry system designed to .15/1950. Just want to know what everyone's thoughts are about not including the sprinklers in these closets. Using the provision 23.4.4.6.2 It would allow me to eliminate 14 sprinklers from my calculation area. Regards Troy
