NFPA 13 - Solid shelving (3.9.3.8)

NFPA 13 - Solid shelving (3.9.3.8)

NFPA 13 - Solid shelving (3.9.3.8)

(OP)
Hi,

In the definition for solid shelving is stated that "Shelves of wire mesh, slats or other materials more than 50% open and where the flue spaces are maintained shall be defined as open racks".

Does the maximum surface area 1,9 m2 doesn't matter for shelves of wire mesh?

I'm curious what you guys think

RE: NFPA 13 - Solid shelving (3.9.3.8)

Can you give the section of 13 this comes from

Does the maximum surface area 1,9 m2 doesn't matter for shelves of wire mesh?

Sorry did not have the book


3.9.3.8 Solid Shelving. Solid shelving is fixed in place, slatted, wire mesh or other type of shelves located within racks. The area of a solid shelf is defined by perimeter aisle or flue space on all four
sides. Solid shelves having an area equal to or less than 20 ft2 (1.9 m2) shall be defined as open racks. Shelves of wire mesh, slates, or other materials more than 50 percent open and where the flue spaces are maintained shall be defined as open racks.

RE: NFPA 13 - Solid shelving (3.9.3.8)

I believe the answer to your question is no

ok, thx.

My customer has got a wire mesh shelve (> 50% open) with a surface area of 3,7 m * 1,2 m = 4,44 m2. It will be suffisant to  maintain flue spaces around this area so we can define this rack as an open rack.

Great. Thx

RE: NFPA 13 - Solid shelving (3.9.3.8)

Covering flue spaces , good question

Some one may reply to that one have to Check the book to see if it says anything

RE: NFPA 13 - Solid shelving (3.9.3.8)

looks like the answer may be no, you can not have anything in the flue spaces, even thought the book does not seem to say it in black and white
