    Marijuana Grow Facility Sprinkler Density

    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...

    Pre-engineered sprinkler design on different title block?

    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...

    Center Axis of Elbows & Vertical Inline Pumps

    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,

    Suspended obstructions within 18" of the Deck

    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...

    NFPA 13 RESIDENTIAL - 4 Adjacent sprinklers?

    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...

    Sprinklers & Track Lights (NFPA #13)

    I generally stay as far away as possible from any light fixtures but I'm working on a project where things are cramped and I'm wondering how to approach proximity to track lights in a kitchen for a NFPA #13 (2010) system. If I use the 4X rule x the largest dimension of the light (which would be...

    Encapsulation

    Below is 13's definition of encapsulation. In a situation where you have a shrink wrapped pallet with a rigid plastic sheathing only on TOP of the pallet it would appear this would not be considered encapsulation per se since it's not "completely enclosing the sides and top". Should any...

    Proper Protocol for Cad Request

    I was wondering what you guys do when you need to request cad files? Do you put this in the GC's lap or do you call the architect direct? What is the *proper* route for this request?

    Diesel Fire Pump Test Loop Overheat

    I know I've seen something online concerning the issue of diesel fire pumps with a flow meter & test loop overheating the water in the loop past the recommended levels. Is this a common occurrence and what can be used to prevent it?

    Is NFPA #13 8.15.1.2.9 referencing a DIFFERENT type of small room?

    NFPA #13 2007 Ed. 8.15.1.2.9 Concealed spaces over isolated small rooms not exceeding 55 ft2 (5.1 m2) in area shall not require sprinkler protection. "Isolated small rooms" is this meant to be a reference to the definition of a "small room" as indicated in 3.3.15 meaning it has to be light...

    Sizing fire protection water storage tank

    When sizing a water storage tank for exclusive fire protection use, and fed by a fire pump, should the tank be sized on 150% of pumps rated capacity (at the req'd duration)or just the fire sprinkler demand + inside hose?

    Low Pressure at Pump Inlet

    I'm working on this project with a booster pump on city supply. I know municipalities like to keep at least 20 psi in their systems - our system is fine there at the point of connection but at our pump inlet calculations are showing 2 psi available after friction losses. there's about 30 psi at...

    Class II Standpipe How many stations to calc?

    I've got a dedicated fire pump feeding a Class II Standpipe system w/ 1 1/2" hose stations. There are 2 standpipes fed from a common supply. I need some clarification on how many stations to calc. From reading NFPA #14 my first guess would be (2) one at each standpipe. NFPA #14 7.10.2.2.1...

    Speculative warehouse??

    I'm designing a sprinkler system for a little 7,000 sq. ft. warehouse with about 1/4 of it being group 'b' occupancy and the actual warehouse being S-1 occupancy. This is split down the middle to accommodate two tenants. The fire sprinkler contractor estimated this project based upon ordinary...
