Yeah, figures - Agricultural Facilities is first on the list and I missed it. I did see 'Tobacco products manufacturing' in there as well which was tipping me back towards ord group II but I think between that and the Ag Facilities there is no question that this needs to have at a minimum an...
I'm having a problem finding guidance on the proper density for a med marijuana facility which is an F-1 occupancy. The existing system is an ancient ordinary hazard pipe scheduled system and as such the limits of the schedule won't allow any additions without major revamping. We've opted to...
It sounds like the 3X rule would apply. Standard 2X4 framing being about 3.5" would mean you would have to be 10.5" from the face of the exposed studs. 8.6.5.2.2 could possibly apply as well.
Also maintain 6 ft min. between heads as previously noted.
Hi Guys,
When project have pre-engineered fire sprinkler drawings it has been common practice for companies that I have worked for to simply cut and paste these drawings on the company's own title block and submit them together with the hydraulic calcs to get a permit. Obviously the PE's seal...
Tyco has one and I was contemplating using it for a 13R today but in the end concluded the patios were "outside the dwelling unit" and figured I should use regular quick response, dry hsw. I was scratching my head as to when you could use the residential ones...
When I tested it was the old way of pencil and paper and they had forms to fill out when you tested if you chose to dispute the way something was worded or whatever. If I recall correctly you just fill out the form and you make your case. As far as appealing a score I'm not sure how you would do...
A pipe hanger is for hanging pipe not for wrapping around structural members. You can point out that the pipe hanger is round for a reason - it's not just coincidence that the pipe also has a round profile. Compare that to the square profile of a joist.
I agree with chicopee.
If you had a backflow preventor in a pit at the same location as your PIV then it would become obvious that it's a little backwards. The FDC is usually after a BFP. Look at nfpa 24: 5.9.3.2 as referenced by chicopee then look at the definition of a 'fire service line' in...
Can elbows be located in any orientation and any location when it comes to vertical inline pumps? All the requirements in '20 for restrictions on the orientations of elbows seem to only be applicable to horizontal splitcase.
Thx,
No diagrams but just picture your deflector 5" above a lot of 12" ductwork trunks. Would the suspended obstruction rule be the applicable code at that point?
I have a situation (light hazard, unobstructed construction) where each office contains both ductwork and 2X4 flourescent lights suspended from the ceiling all within the 18" envelope from the roof deck. There are no ceilings, everything is open to structure. The roof is sloped (.5:12) so there...
Travis,
You don't even need a calculator to figure out which sprinklers are going to be more demanding in the scenario I'm presenting - the issue is more about the words 'adjacent' and 'contiguous'. Does that mean the sprinkler next in line on the branchline has to be included in the...
Right Pyrophoric,
But now let's say the 256 sq. ft. sprinklers are 5.6K and the 324 sq. ft. are 8.0K - because they're in different size rooms the larger k-factors are not needed in the smaller sq. ft. areas. It seems to me you would still have a mix of 256 & 324 sq. ft. sprinklers either the...
When we calculate 4 adjacent sprinklers in a nfpa 13 system (residential section) we're suppose to calc the four sprinks which create the most demanding condition. I believe the handbook uses the word 'contiguous' to further describe the situation but my question is this:
You have a line with...
You can usually just grab your calculator and determine what's going to be the most demanding area and it only takes a minute or two. In Travis's scenario you could calculate the design area for the two areas in question and start multiplying the number of sprinklers by their densities and look...
