Re: Fire pump removal

I hate to make a decision or recommendation without knowing the whole picture, and on a forum such as this it's impossible. But a sprinkler system is such an integral part of the evaluation of a building, and occupancy, that it would be unlikely that the business would be allowed to stay open

The exhaust stack has a total length of 20'-0", there is a head at the top of the stack and heads behind the filters, the fan is located at the base of the stack. Thank you James Crawford Phaser Fire Protection Ltd. Phone 604-888-0318 Fax 604-888-4732 Cel 604-790-0938 Email

RE: Paint Booth Exhaust Stack

We have a head at the top but as it comes down they had to offset to miss a joist so there are 2 90 degree bends and a small pup piece that make up 24” center to center, just trying to see if we need a head in the offset. Thank you James Crawford Phaser Fire Protection Ltd.

Is that the total duct length or is there a riser to the roof? Are there heads in the plenum behind the filter? Where is the exhaust fan? Art Tiroly ATCO Fire Protection/Tiroly 24400 Highland Rd CLE 44143 216-621-8899 216-570-7030 cell From: Sprinklerforum

Re: Paint Booth Exhaust Stack

My read on this would be that if you gave a sprinkler in the middle of a 24" horizontal duct you have 12" on center. Don't you need one at the top of each vertical run? On Thu, Mar 16, 2017 at 1:47 PM James Crawford wrote: > NFPA #33 (2016 ed) section 9.4.6 (2)

Would a wood framed corridor rocked with 2 layers of 5/8" gyp bd (a UL listed assembly) and a dropped acoustical grid ceiling still require sprinklers? Would NFPA 13 :8.15.1.2.10 permit the exclusion of sprinklers from such a space? 8.15.1.2.10 Concealed spaces where rigid materials are used
