[Sprinklerforum] Re: Low Decks

That’s kind of the track I was going down but didn’t think it fit well because of the “non-combustible overhang” and “tight construction” phrasing. I like Rick’s thoughts about limiting the debris accumulation. Minnesota has an amended fire code that addresses 13R decks and the cutoff is 6

Taylor, Rick is on the right track on this. Check out 9.2.2 in NFPA 13-2019. This section allows sprinkler omissions from underneath ground floors, exterior docks, and platforms, with your decks likely falling into the platform category. There are a few requirements, one being that the area is

As an old AHJ, I would require you to screen in any unsprinklered decks that are permitted to prevent accumulation of debris beneath them. Rick Matsuda > On Mar 8, 2023, at 9:04 AM, matthew.will...@ferguson.com wrote: > >  > This seems like one of those great communication with AHJ/Owner

[Sprinklerforum] Re: Low Decks

This seems like one of those great communication with AHJ/Owner opportunities. A deck is an exterior projection. I am assuming the deck is wood, and no fire-resistant stuff. The only thing height wise is the 24" for obstructions over 4 feet, and the 48" for stages, with stipulations. IMHO,

Agree - I used to enjoy PDFs. I cringed when I heard they were leaving but I understand why NFPA was discontinuing them. We switched to Link and I like the features and access. NFPA has done a great job with Link. Try it out, with a free trial and I feel you will not be disappointed. Thanks,

[Sprinklerforum] Low Decks

Is there any guidance on sprinkler protection under decks that are really close to finished grade? I have a 13 project with combustible decks that range from 1 foot to 8 foot above finished grade. Common sense tells me these short ones won't allow spray pattern development and replacing/testing
