Hello Todd, I also found no protection criteria for bulk storage of various commodities other than FM Global's Datasheet 8-27, which applies strictly to piles of wood chips. Furthermore, the design density and area spelled out in that datasheet are the same, regardless of the storage height. (0.20/3000 to 0.2/5000, depending on type of system and temperature rating of the heads).
I am not convinced that a fire involving the materials stored at the facility in question would progress in the manner as in a pile of wood chips. Thank you for your input.

In my situation, I have a 20 ft pile of mixed household recycling including cardboard boxes, plastic and glass bottles and metal cans. Based on a similar pile at this location, I called it a Class IV commodity. Construction debris is a little different. Not sure where that would fall. The only reference I could find for "pile" storage is in FM Global standards for wood chips. They have a moderate density over a large area. Keep in mind that in these type of situations, the goal may be to contain the fire and send an alarm. Extinguishing would be by the fire department and probably take a long time to get everything finally out. It would be nice to consult the EoR, but there very likely isn't one.
