Clearance from deflector to bookshelves
Clearance from deflector to bookshelves
(OP)
All,
I have an issue with tall bookshelves coupled with a low ceiling. Is there any way to arrange the bookshelves and sprinklers such that 18" clearance from deflector to top of the shelf is not required?
Everything I read in NFPA 13 says no, but I thought I'd ask anyway..
The only thing I can come up with is to build a wall behind each shelf, and take advantage of A.8.6.6 interpretation.
TIA. Thanks In Advance

RE: Clearance from deflector to bookshelves
Would it be possible to use NFPA 13 2010 8.6.5.2.2 and classify the bookcase as a floor-mounted vertical obstruction? Table 8.6.5.2.2 then allows the top to be 3" below the deflector.
Might be a stretch considering this "room divider or similar obstruction" is full of combustible material, but given it's a light hazard occupancy...could work.
