The closest criteria is 20.6 for Class III commodities (for folders
and Misc storage though I only remember the folders) and treated as a
Light Hazard occupancy classification. If memory serves me right,
some of the testing took like 40 minutes before activation of the
sprinkler. The folders were still fairly tight with minimal excess
room so the fire spread was very slow. The metal barriers should be
noted along with the max area of 250 sf (as measured between
longitudinal barriers). Look at the ROP and ROC for 2010 ed (found on
the NFPA website under the list of standards)

Good Morning!
There is a thread concerning this issue from 2008 with some
reference to
upcoming documentation, but I do not know where it exists..
We have a military facility with the rolling storage cabinets with
large
compartments for storing "gear" - "gear" varies greatly.
It is only about 7' tall and there is more than 18" clearance from
the top
of the cabinets to the sprinklers. Currently, there is about 14'
clearance
and the bldg is designed for OH2, this storage is only about 10% of
the
entire bldg footprint. Now they are building a mezzanine over the
cabinets
and there will be about 3' of clearance. I guess the reationale
would be
that the OH2 should still be sufficient?
Thanks,
