Paint booth sprinkler k factor
Paint booth sprinkler k factor
(OP)
As per NFPA I'm designing a paint booth to extra hazard group ii... now the question is: does NFPA say anything anywhere about the sprinkler having to be a minimum 11.2k? I'd like to use 8.0k in this specific project. Most designers will reference the 0.2 to 0.34 densities with 8.0 k and 0.34 plus with 11.2k plus BUT that is within NFPA's section on storage. Can't find anything elsewhere but perhaps I'm missing something?

Don't forget the 30 gpm or 15 psi at the duct. That caught me in the past and made for an interesting fix. You can infer from the 15 psi (30 gpm) that a K8 sprinkler is permitted at that duct stack which is in the paint booth section, so that is more reinforcement that k8 is permitted.
