On the last automotive plant we did the tunnels under the stamping processes were conveying scrap as you describe. There were no fines, no small particulate. The conveyor belt was non-combustible, FM approved belting system and there was no combustible residue on the scrap parts. There was no hydraulic piping or other piping conveying flammable or combustible liquids or gases in the tunnels. This was an FM project and the prescribed design criteria was .020 over 3,000 sq. with 500 gpm for hose, heads were 212F since the space was non-conditioned.
I'm surprised something like this wasn't spelled out on your contract drawings. Craig L.

The tunnels are under floor and covered by the floor slab, pits are open grating under machine. Would the tunnels be considered OH II as there is only a single floor mounted conveyor carrying scrap out to a dumpster room, and under the machines be EH I or OH II. Apparently I'm missing the direction from 13 on this. Thank you in advance, Bobby Gillett Sr. Project Manager Key Fire Protection, Inc.
