Why not a large orifice sidewall at each side of each trailer?
Going back to objectives, and what is not objective. Writing it out helps, at
least me.

Why wouldn't you just install a one hour rated door at the opening held open by
a fusible link. When they have a fire in the pallet trailer, it would probably
take 10 minutes to pick it with a dolly and move it to a safe location away
from the dock. Or 20 minutes to become a smoldering pile of a

I would ask them how that is a listed discharge device required per NFPA.
If you can get past that, I would just ask what is the minimum flow and
pressure they require at the point of connection to that pipe. It sounds like
they have done this before.
