OK, if there is no container and it's just the cups shrinked wrapped I would have to consider that UNSTABLE, which weird as it is, would put in in that Column "A" with the lesser density. Is it even rigid enough to stack 18ft high?

I guess FM favorable is the same as NFPA Column A. The storage arrangement is 40 oz. cups stacked inside each other 4 ft high on a pallet, shrink wrapped on four sides with a single layer of cardboard over the top.

Per 15.2.8 you can interpolate based on storage height so at 18ft of storage you'd be at 1.0/2500. Plus 500 gpm hose. But also and depending on how the stuff is contained on the pallet you may be able to go to Column A @ the 0.6 at 20ft and interpolate that to .54/2500 at 18ft. Need to verify how the stuff is packaged onto the pallets per the definition of Solid Unit Load in NFPA 13. For ESFR 14K @ 75psi down to 25.2K @ 20psi or anything in between per Table 15.4.1 Alright, back to business, everybody man your BUCKETS!!!!!!!! Craig L.

I find .6/2500 for favorable factors and it sends you in a circle for no favorable factors. NFPA is 1.1/2500 or ESFR. Something doesn't compute (probably me).
