I have searched the from the deepest depths to the highest heights within NFPA 13 for a solution and am coming up empty.
We have a freezer warehouse, storing packaged meats on foam trays which are placed in plastic trays. The frozen meat per NFPA 13 is a class III, the kicker is the exposed, expanded plastic tray which represents about 63% of the package load. They claim to only put about 2.5 lbs of meat in a plastic tray that weighs 4.4 lbs. This is pushing us into considering this as a Group A plastic commodity. I have found no system criteria for a freezer warehouse with 22' of racked storage and a 30 ft ceiling/roof height and exposed, unexpanded group A plastic. Any options we find show them as being Wet systems only. I am starting to dig into the FM data sheets but was looking to see if anyone has any insight or if I've missed some option hidden away in the dark corners of NFPA 13. Quell only goes up to Class III commodities.
