Todd, I had to think about this one awhile. When I was with the Fire Marshals office in Phoenix, we (the City of Phoenix) built two waste recycling, sorting and transfer stations. As I recall, the design density was 0.25 gpm/ft2 over 2500 ft2. Looking at the Figures in NFPA 13, for piled storage protection, that puts it smack in the middle of the Class IV curve using high temperature sprinklers at 20 feet high storage. That pretty much agrees with Mr. Sornsins recollections for his facility, and it is a design that I was comfortable with.

I would expect fires in transfers station piles to behave similarly to baled waste paper fires, with added heat release from the plastics. On a facility like this a number of years back, we married the requirements of FM data Sheet 8-22 on baled waste paper storage with the requirements of class IV solid pile storage (or maybe we used plastics?). Can't recall the details, as they were left behind at a previous employer - but that was the concept. Mark A.

In my case I had a cascading pile about 12-15 ft high of Class IV (based on observation from existing facility). I was considering adjusting the requirements for a pile of wood chips (Class III) to Class IV. >From a letter I received off Forum, supposedly AFSA has information on loss >history, but I haven't been able to get a hold of it.
