I haven’t reviewed that lately, but I can take a look tomorrow. I do know
that FM has required sprinklers to be installed parallel to the floor in
storage applications where NFPA currently requires sprinklers to be
installed parallel with the ceiling.

Kevin,
Do FM data sheets now reflect results of these tests?
Best.

There is an active FPRF project that addresses storage occupancies and
sloped ceilings. It is currently in its third phase, and there has been
some full scale testing at FM that I have witnessed. We might see some more
options in the 2025 edition of the NFPA 13.
Kevin Hall, M.Eng, P.E., CWBSP,
Thanks all. It was a brain F$%t on several levels. The project causing my
query isn't sloped (1:12) anyways . I can't imagine why I included it in the
question.
But I've had more coffee now so

Steve is correct. Protection schemes are available to some extent by
others; but currently not NFPA 13. My only point was to respond to the 30%
increase due to slope as required by NFPA 13. Engineering judgement or
other standards will need to be applied to those situations.
The above is my
I assume this statement of intent was added because full-scale fire testing has
only been undertaken in test cells that have flat ceilings (I would very much
appreciate input from the manufacturing community in that regard). But that
doesn't mean that we don't have to fire protect storage
As Travis stated, slope ceilings are not covered under the protection
schemes of NFPA 13 for "Storage". Thus, the increase does not apply to
"Storage" unless miscellaneous or low-piled storage applies.
NFPA 13 - 2019: 20.6.1 Ceiling Slope. The sprinkler system criteria
specified in Chapters 20
Slope >2:12 is not allowed for storage. So, you don't apply because it is not
permitted. Dry system increase - yes.
If you are talking misc storage or low pile where you use the OH or EH curve
then yes, slope and dry increase.

I know this answer is obvious before I even ask the question but for some
reason I am befuddled in brain lock (must be Monday again today)
Do you have to apply the area increase for dry systems and sloped ceilings to
the area of operation for storage applications?
