RE: INDOOR SPORTS FACILITY FIELD HOUSE

Not in my opinion. We should always look at the definitions for each occupancy classification as opposed to the list in the annex. These facilities have a lot of plastics and combustibles that exceed the definition of light hazard and they are of heights exceeding 8 ft so OH1 is probably not

RE: swimming pool

For what its worth, in the 2013 code cycle of NFPA 13, I submitted two proposed changes related to this topic. The first was to eliminate sprinklers directly above the water where indoor swimming pools were present. This was rejected by the committee with the statement that indoor pools are not

RE: Purpose of Subdividing Dry Systems?

As noted in the NFPA 13, 2013 edition handbook, "Prior to the 2010 edition, 7.2.3.9 conflicted with the requirement in 7.4.4.1 that combined dry pipe and preaction systems be subdivided as well as contradictory to the requirement in 7.9.2.8.4(5) for separate indicating control valves and check

Re: Sprinkler protection in a freezer warehouse - with plastics

Craig, As you know, the commodity classification is based on the product, the packaging and the pallet type. As such, your foam trays have to be taken into account by weight or by volume. NFPA 13, Fig 20.4.3.3(a) and (b) and I don’t have a book with me but pretty sure frozen food on polystyrene

Re: NFPA #30 Containment

I am out of the country (without my books) but from recollection, the time frame is based on the H occupancy classification form the IFC/IBC, where H9 has a longer duration than H3. Not sure its in NFPA 30. It’s definitely sprinkler discharge rate plus the volume of the largest vessel though. I

Re: Mechanical roll-grooved fittings for fire pipe

NFPA 13 does provide rules for grooved piping. These rules are copied from the 2016 edition, so the current edition section numbers will be different. 6.5.3.1* Pipe, fittings, valves, and devices to be joined with grooved couplings shall contain cut, rolled, or cast grooves that are

RE: Attic protection over a storage occupancy

NFPA 13, 2019 edition section A.4.3.2(16) lists unused attics as light hazard. That said, it's always better to consider the definition of the hazard as opposed to automatically applying the lists from the annex. Section 4.3.2 defines LH as spaces with low quantity and combustibility of contents.

RE: Fire Pump Room Sprinkler Classification

NFPA 20 is clear that the pump room is to be protected per EH2. By definition of EH2, the presence of the diesel fuel makes it EH2. See 4.14.1.3 Bob Caputo, CFPS President American Fire Sprinkler Association -Original Message- From: Sprinklerforum On Behalf Of James Crawford via

Re: Available Pressure from Fire Water Storage Tank

No, you are not permitted to use elevation pressure from a gravity tank. You do not know the elevation of the water in the tank which is depleted during the operation of the systems in fighting the fire. You are permitted to use the pumps productive curve at 150% of rated flow and 65% of rated

Re: [EXTERNAL] Fire Pump Sprk & Fire Flow Demand

Lots of great responses to this question, the best of which is that it is really up to the local AHJ to determine what will be required. That said, in the context of NFPA 13 (2016 edition) we should note two specific applicable sections in consideration of the issue: First, section 3.8.2.1.3

This may have been approved by the local AHJ, which would be the appropriate assumption based on NFPA 25. We are not doing a design analysis. On Thu, Apr 8, 2021 at 9:34 AM Dale Wingard via Sprinklerforum < sprinklerforum@lists.firesprinkler.org> wrote: > Sounds like the intent was to protect

BTW, I probably should have included in my comments, the requirements for floor control valve assemblies in NFPA 13, 2019 edition section 16.9.11, which might be applicable to Jerry’s situation. Again, I may have missed the point of the original question…. But I’m old so I have an excuse!

Re: Different Levels of protection open to each other in the same hazard

Jerry, NFPA 13 is clear that it is the designers responsibility to design the system and chose the design method. It is the AHJs (reviewer’s) responsibility to review the submitted design for acceptance to adopted codes and standards. Unless the reviewer in your case is the owner’s
