Can someone point me in the right direction. I'm trying to determine the
density for a project with the following conditions:
Rack Storage
Class III encapsulated
Double row racks
4'-0" aisle width
38' storage height
48' ceiling height
Solid shelving
NFPA 13 2007 ed.
I know I cant' use ESFR's and will have to place sprinklers at each level
of
shelving, but I can't seem to be able to nail down the ceiling density.
Thanks for your help.
