The tents are (likely) a" vinyl-coated polyester scrim" so, despite fire retardant coating, like FR coating on mattress covers, sounds like Group A Uncartoned (exposed) Unexpanded, whether hanging in the drying area or folded and stored in the double row rack storage area.
For those that actually miss the fun of NFPA 231C, try FM DS 8-9. Brings back memories, except prelim calcs are easier with today's software and laptops. George L.

The flame spread rating of the tent material would play a big part. Other operations in the space could play in to it. Adds up to a lot of stuff to consider. Sounds like it need a little engineering first. My guess from several hundred miles away would be at least OH2.
