The 2016 NFPA 13 handbook states that canopies less than 4' are not required to
have sprinklers, regardless of construction type, unless combustibles are
stored under them. Projections 2' or more require sprinklers, regardless of
construction type, if there are combustibles stored below it.
Bi
8.15.7.1 boiled down says projections over 4' have to be sprinklered underneath
unless they're the stuff outlined after, non combustible construction, or
non-combustible facings with sprinklers inside or 1 of the three exceptions
noted.
8.15.7.2 is a standalone, regardless of what you've had to
Bill I looked back at the handbook and the standard to make sure I
understood the intent.
I'm not attempting to split the atom, however I note that the 2'
projection described in your post should include the phrase "greater
than 2 ft" as identified in §8.17.7.5. If the projection were exactly
You are correct. Thanks

Applicable code/standards would be IBC 2012 and its references (NFPA 13 2010

I'm not coming up with a "why not" for this, but it doesn't give me a warm
fuzzy. I have a wood framed "pole barn" being used for plastic storage in
racks. The building is a standard 4:12 wood truss building w
No building size is indicated. Does the building code require protection?
Plastic storage may be considered a high hazard.
If protection is a code requirement then the attic requires protection.
Without protection a fire in the attic will likely cause a total loss of the
building and contents.

Maybe I wasn't clear, this is an existing unsprinklered building attached to a
sprinklered building at a firewall. I presume when constructed it was per
code. The intent is to add fire protection at the request of an insurance
company. All areas would be protected as stated, my concern is whe
A-okay - Absolutely two different design criteria: attic above is light
hazard and your system below is group 'a' plastics storage commodity. I
would do it the same way. There's no need to design the attic to the lower
area storage density in your case because they're not storing group 'a'
plastics
NFPA 13, 2019 edition section A.4.3.2(16) lists unused attics as light
hazard. That said, it's always better to consider the definition of the
hazard as opposed to automatically applying the lists from the annex.
Section 4.3.2 defines LH as spaces with low quantity and combustibility of
contents.
Mike,
That is an interesting situation and thought.
I would defer to Messer's Hall and Denhardt.
For CMDA sprinklers there are requirements in light and ordinary hazard, but I
don't see specific reference to combustible roof materials for storage and CMDA.
The are limitations for spacing of CMSA s
There is no requirement to separate occupancy/storage design areas other
than the more demanding space has to extend 15 ft when no draft curtain or
similar barrier is provided to contain the heat and smoke to one design
area. In this case, it would seem that the space above the storage
occupancy is
