That could be challenging within a building where the only access is through a
loading dock.

The only experience I have had was hay stacks outside. The only way we were
able to control the fire was to have lots of water, either a ditch close by
for drafting or water relay and portable tanks. We used 1.5" hoses on each
side of the stack, while firemen kept watch on the stack. They directed
tractors with grappling hooks to move burning material away from the stack,
and spread that hay on the ground. More 1.5 " hoses sprayed the burning
material on the ground. Spotters watched for burning material and watched
to make sure the tractors and firemen did not get close to each other. All
this only worked if we got there early enough, had enough water, tractors,
manpower and enough ground to spread the hay out. Usually, we just
protected exposures and watched the stack burn.

Hay makes me a little nervous. I'm not sure it would burn like a standard
class
III. You could have the potential for a deep seated fire that sprinklers
might
not be able to easily contain. To fully extinguish a fire, you would
probably
have to remove the burning (or more likely smoldering) bales from the
building,
break them apart and wet them down. In that way, it may behave more like a
commodity such as piled wood chips. Anybody with first-hand hay fire
experience
out there?

Seems like 15' storage of solid piled class III commodity to me. Of course,
FM
jobs would need a ceiling height as well.

Baled Hay (Alfalfa) in a warehouse. On conveyors and/or staged for loading
trucks etc. Could possibly sit overnight stacked up to 15 feet ...
