Combustible Stairs
Combustible Stairs
(OP)
Nfpa 13 requires sprinklers beneath all stairs of combustible construction. To comply with this, I believe we need sprinklers at each floor landing, not just top and bottom as in non-combustible stairwells. Would this be correct or would someone say the mid-landings need sprinklers also. Thanks for your help.

What about a 30' long linear combustible stairway with sloped ceiling and a landing a halfway down the stairs. Do we install 5 sprinklers total: 1 to protect the top landing, 1 to protect below the top landing, 1 to protect above the mid-landing, 1 to protect below the mid-landing, and 1 to protect the bottom of the stairway?
RE: Combustible Stairs
1. Protection under combustible stairs and that depends on if they are emclosed or not and if enclosed do they meet an exception
2. Than you talk about protecting the landing, which I take to mean sprinklers at ceiling level to protect the walk way.
So do you want to restate your question or am I wrong?
