AFSA Forums:
I want to clear up a question that has been bothering me since looking at plans for an addition to an existing warehouse. The project is a plastic manufacturing and warehousing facility of non-combustible steel bar joist construction. The storage height is limited to 8' max. The design layout is CMSA VK580, 16.8K sprinklers spaced at 100 sq. ft . The design density is .45 / 2500 sq. ft. My question is this; according to figure 11.2.3.1.1 this is a Ex Haz Grp II density and by my interpretation, the overhead system should be limited to 40,000 sq. ft. total area. However, the existing system that was done by another contractor covers 50,000 sq ft. Have I been looking at this wrong all these years since 231-C was incorporated into NFPA-13? Is storage of PVC plastic commodities to 8' an Ord Haz Grp II occupancy?
