I just got involved in a storage facility design for a client who is looking to store roll paper in a 40 ft stack. I have not been able to get the paper weight or the array confirmed, but based on pictures and process I believe it to be mediumweight wrapped with 40 lb paper (so, treated as heavyweight).
I have designed rack and pile storage sprinkler systems before, but this is the first time I have dealt with Roll Paper storage specifically, and so I was quite surprised to see that NFPA 13 (2016) only allows for storage heights up to 30 ft (ESFR) or 26 ft (CMSA).
Is that indeed the height limit for roll paper, or am I just missing something blatant? I am essentially looking for confirmation that I am indeed following the right information within NFPA 13, and there is no caveat or alternative that would allow the paper to be stored above 30 ft. The client claims they have another facility that stores at 35 ft, which I am thinking is not allowed, but its gotten me suspicious enough I would like a peer opinion.
Thanks all!
Banded or un banded?
One of the first fires I saw was rolled paper for newspaper use.
They made the mistake of having the rolls against the wall. They got wet, expanded, and pushed out the walls.
I think with in un banded you get the roll possibly whipping off, exposing more paper to the fire.
Look at the A section of chapter 19 2007 edition. It shows some testing and failure criteria, which appear to be based on FM testing.
You might see if there is a FM data sheet for rolled paper storage, to see what design factors they use.
