It's a solid pile, this I know. If a fire is working outside of the boxes it could involve them and they would behave predictably I think - they'd spill contents at some point but contents are mixed, so I'm not thinking free-flowing or anything like that. The plastic tops become a factor if the fire starts INSIDE of a box, especially a lower one. Not sure what else to do about it except call it Group A (which it's most certainly not) or upgrade it to ESFR arbitrarily. Shielded commodity would be Extra Group II, so you could arbitrarily upgrade to a .40 density if you're not there already as a Class 4 solid.

NFPA 13 has identified that LARGE containers of household storage is not addressed by the classification section. If memory serves, the plastic roof derailed any discussion on smaller containers. Naturally there is nothing to quantify how large is too large.
