I am doing a research project on this material to verify it's proper fire classification in regards to high pile storage. The MSDS does not help much - but that is no surprise. The product form is expanded, un cartoned, ie, large buns. FM classifies polyethylene as a Group B. The IFC (2010 CFC)...
To the MOE experts out there; I am working on a project where a large warehouse is going to have the existing sprinklers removed, and ESFR and a pump will be added to accomodate a new tenant. There is an existing, rated exit tunnel that runs from the center of the warehouse, to an exit door on...
The brief scneario: Large (5x7x7ft) wood crates (called vaults in the moving industry) in an ESFR building, peak 40 ft. to be stored solid piled on the floor. The crates will have household furniture inside them, so i can consider the stuff inside, Group A, unexpanded. However, these are heavy...
Racks to 15 ft with class 1-3. Sprinkler densities and the usual stuff is generally ok. One, 50 ft long rack section is right up against a glass window on the exterior wall of the building. Dont ask me the rating, i have no idea, but it is tempered glass so it may last a few minutes. The area...
Scenario: Lab with typical 6 ft wide, steel, flow hoods where several gals of flam liquids are mixed, dispensed, etc by chemists - we have all seen it before. Steel exhaust duct (most likely 4 in diam) to roof to remove vapors. Exhuast rate within hood to be calculated to ensure LFL < 25%. The...
I am curious as to what websites others are using to quantify liquids, gasses, etc for hazmat purposes. There are quite a few government and university websites, but the ones i have found are not that great.
Anyone know of any good computer based programs? I dont mind paying for the program...
S-1, Type III-N, rack storage Class I-IV, but also fairly large amount of Group A, unexpanded plastics.
-Sprinkler protection (ceiling only) adequate for the Class I-IV per engineering analysis I did.
-Sprinkler protection is not adequate for the plastics – shocker. They will either need to...
NFPA 13, 2007, Table 17.3.3.1 allowed K14, 12 @ 75 psi for 30 ft of cartoned, unexpanded plastics within racks. There are mega millions of big boxes out there with this design.
I just looked this up in the 2010 version of 13 for a project I am working on, and the K14 option is gone for 30/40...
Most of the property insurance companies have some good hot work permits - FM's is the best. Anyone know where i can get a good hot work permit to give to clients? I cant find anything in NFPA 51B.
Same question for tagging out a fire system/fire control valve. I recall seeing a very simple tag...
Chapter 24 of NFPA 13 has something i have never seen. This is a project summary of the storage heights, combustible liquids, etc that the sprinkler system design was based on. This is to be hung on the riser. Keep in mind, this is in addition to the typical hydraulic design placard that is...
The details:
-Large warehouse.
-Rack storage class,III-IV, but also large amount of Group A, unexpanded plastics, cartoned mixed throughout – typical of most warehouses these days.
-Because of plastics, overall commodity is “high hazard” (most restrictive governs).
-Sprinkler system designed per...
I am new to this board, so i did a search and found a few things on this subject, but nothing appears to address my issue:
Situation; Double row racks >25 ft storage height, overall Group A plastics, cartoned. ESFR, ceiling only system.
In my previous life, I used the FM standards to define...
Hi, I have a project in So-Cal where my client will be occupying about 250K sq ft, of an existing, 500K sq ft bldg. There is already a tenant in there, with mostly storage (S) and some offices (B). My client will have the same occupancy, mostly storage, and some small offices (S/B). Per the Cal...
