Dear Forum members,
I am investigating a case where 10 out of 45 sprinklers were found open
causing total loss of food raw material .
No fire traces were found.
Normal static pressure is 75 PSI.
There is a report that the municipality shutoff water supply and reopened
the supply during the
Got an elevated non-combustible equipment access platform that is 8 off the
floor. The contractor is informing the GC that because the platform is over
48 wide there needs to be sprinklers below.
Trying to put this fire out and it appears the NFPA 13-2007, 8.15.6.2 would
cover it.
However
Is it enclosed concealed space under the platform except for the perforated
deck? Guess I haven't seen any equipment platform that is enclosed underneath
making them all need heads. But if it meets #1 and the only question is tight
yeah I think so. I think the requirement is to keep trash
The day I stop learning, I'm dead. :) I'm interested in knowing why the NFPA
13 Committee has such issues with heat trace if it offers no other sufficient
alternatives (other than antifreeze which has enough challenges of its own).

8.15.6.1 refers to combustible platforms. I think 8.16.5.2 #3 is there in
case the platform is made of grating. The handbook says 8.16.5.2 is there as an
exception to the rule that all combustible spaces be sprinklered.

From:
does anybody else find the fact that the floor itself is an obstuction
to pattern development a bit disturbing? at 6 feet between sprinklers
with 7 inch max deflector above the floor, the 'dry spots' are going
to be 2 or 3 feet long!
Quoting rfletc...@aerofire.com:

Craig,
We just had a similar case yesterday where we successfully used this section to
eliminate coverage. This platform was not grated however. I think the heart of
the question is does this meet the 8.15.2 (3) requirement of tight
construction? I had it in my mind that this was to slow fire
Let's review the conditions:
This is indoors so trash accumulation is a non-issue.
It is 8 off the floor and the space between the deck and the floor is enclosed
with sheet metal.
The platform is movable by fork truck for equipment maintenance access, it is
not permanent.
One small section
Since it is a moveable object, sprinkler protection is impractical. However, if
the hydraulic fluid is combustible and there is a leak, fluid could end up
under the platform and the potential does exist for a shielded fire. What is
the surrounding occupancy and what is there for sprinkler

If we have sprinklers adjacent to an unprotected combustible concealed space,
the design area has to be increased to 3000 sqft. However, since you already
have the 3000 sqft, you would be good on that score. Being that it is a n/c
space, I think you can claim (to whomever) that you are good and

Dear @riskmanage,
there is no similar experience: this is a clear case of present/former
drinking buddy vandalism. the report from the municipality is
superfulous (a worker there noticed a spike in usage, shut it down,
drove around town, saw no prob., brought it back up). By this time the

That's it.
It should be noted though that a single rack against the wall is treated as a
double row rack with the gap between it and the wall being the longitudinal
flue. That's why it shows up in Figures 16.3.4.1.1.1 (a) through (j). Ain't
that a kick in the head?
