Seems to me there is a grooved transition piece available.

Hi everyone.
I recently was made to look very bad by a local AHJ because I told my client
that small hose stations were required for his high-piled combustible
storage facility (50,000 square feet plus of class IV commodities stored up
to 20 feet high). The client complained to the AHJ about h
And if baled too wet that mold can produce heat and eventually combustion. I
don't know if this influences the protection scheme or not, but you could
theoretically have a fire begin at the bottom of the stack (if it can get
enough oxygen) and be quite large before producing enough heat to acti
There won't be any wrapping, the hay needs to breathe. Otherwise it will
become moldy. I spent several teenage summers "bucking" hay from the fields
and stacking it in the barns.
I would classify it as OH Group 2.
As for the storage standard, from my experience it is standard practice to

Has anyone ever tried to cut groove cpvc?
The reason I ask is it might save on that 'last' joint and cut-in times
(which nobody in these parts it seems but me follows, but I'm venting).
Does anyone out there have a cut groover?

Look at stable protection. Also, somewhere I seem to recall that you have to
treat it like Group A Plastic.

Will it be a solid pile or an open array? (I am picturing a barn with a solid
block of hay bales at one end)
Will the bales be wrapped in mesh or plastic wrap? How tall is the building
deck? Round bales or square?

Forumites,
Can someone give me guidance to the storage standard for protection of this
commodity?
Client would like to store to 20' of hay bales. Pile size undetermined.
Prefab metal structure, 40K sqft.
Any input would be appreciated.

For a less expensive option there are also desiccant dryers available. They
don't get the air quite as dry, and they require more attention, but the price
difference is substantial.

Also keep in mind that, at least with the Tyco K-17 ESFRs, the upright
version cannot protect uncartoned unexpanded plastics, while the pendent
can.

Most air dryers are designed to work best at cooler ambient and compressed air

pre-cooling the compressed air is advisable. If dryer is mounted outside or in

According to the Viking data sheet on the ESFR, it appears to me to be
less restrictive on obstructions, and it says mixing ups and pends is
acceptable to the manufacturer ( with AHJ approval)

Dewayne,
You're absolutely correct. From the new FM 8-9, 2010 edition:
2.3.3.6.4 Do not mix sprinklers having different orientations (i.e.,
pendent and upright) on the same ceiling-level sprinkler system within
the same protected area unless indicated otherwise by this data sheet.
If you look
I would be careful mixing pnd and up. I think I read in the new 8-9 FM
storage standard that you could not mix the two.
Don't remember seeing this in 13 (10ed) but it could be there.

Perhaps semantics but I believe FM has done away with the term ESFR. Mfg's are
rewriting their cut sheets to the effect. You are correct on pendant is much
better than upright in some cases even when the upright is putting more water
out.

The upright ESFR is less of a problem with obstructions, you may pay a
little more but can help a lot with obstruction issues and you can mix
pendents and uprights.

Check out FM's new DS 2-0 which includes some interesting changes regarding
ESFR's based on recent testing. As I recall, the downward momentum of the
water out of pendent ESFR's was demonstrated to be superior in getting through
the fire plume, hence listings for ESFR pendents going forward dif

I know a couple years ago they only made ESFR heads in the pendent position,
now that they make them in uprights as well is there a benefit one way or
another these days with still sticking to the pendent only method? I know
you get a couple extra inches of space allowed from deck to deflector but
