Look at NFPA 15 for conveyor protection for water spray systems, this may
reinforce what you are looking at, perhaps substitute sprinklers instead of
water spray

The question is does a mezzanine count as a story? My past experience has
been, NO, a mezzanine, that fits the definition of mezzanine in IBC, cannot
also be a story, rather it is considered a part of the story within which it is
contained.

Tony,
My take is that you are obligated to provide protection at the deck 1st, and
then everything else becomes a potential obstruction to sprinkler discharge
below. In this case it seems you will also need to drop protection into the

From
many
unanswered questions here. The NFPA 13 standard states that you do not have
to include heads added due to obstructions to the hydraulic calculations,
for a head or two here and there, but to apply it to an entire 50 x 50
mezzanine is a BIG stretch. Just my 2 cents
Jeff Hewitt, PE, SET,
Will NFPA 13, 2007, 8.15.1.5 work for you?

Ray,
NFPA 30 or even 30B if you have any aerosols is a good place to start. If
you don't find anything to your liking, you may also want to review the
applicable FM Data Sheets on Flammable and Combustible Liquids to see if
they have a protection scheme to match your situation.

Andy,
Be careful with this one. It seems to me that the storage as described
would constitute Uncartoned (Exposed) Expanded Group A Plastics (NOT Class
IV), which have VERY limited applicability for ESFR.

for that matter to try to "sell" it to the local AHJ. Do you really want
that liability? Not to mention whether you are exceeding your "authority"

Co
Brian,
Sorry,
I don't see it that way. It does not say that this only applies to
obstructions up to 9-in wide or your up a creek.
What it does say is that if you are 36-in away that is all the further you
need be.
Contact me by phone to discuss this. I am in the office.

Brian,
I believe it should be read to mean that the most/furthest away you have to
be is a maximum of 36-in. The 36-in. is the maximum limit. Without this
provision, you would instead need to be 4 times away or 96-in.

maybe thinking
this is an ordinary hazard occupancy, and ESFR is allowed over OH

Russell,
My take is that if you are using residential heads, and residential head
design criteria, then the 3000 sq.ft area does not apply because you are not
utilizing an area/density design.

I hope this works for your application. Besides corrosion, our concern was
with hot water and steam eventually eroding any wax coating.

Brian,
Just curious...
What were the circumstances that led you to use a test conducted by the Fire
Department? Are there conservation limitations imposed or something like
that? Why would you not have performed your own test?

rather than seeing all of these complaints about inept specifying
engineers, let's all do something different now, or it will only get worse.
Gather your facts, file the complaint, and turn them in.

plumber won't have to do any engineering? Who will evaluate these and other
changes?

g, and is not, in my
opinion, is an ordinary hazard area rather than light hazard. And because
it's storage, and you don't know what could go in there, OH1 ain't good
enough, it needs to be OH2.
Just my opinion
