I am working on a building with a 3:12 roof trusses where they want to store Class III commodities to 12 ft. Since the storage area will exceed 10% of the building area, it is not considered miscellaneous storage (Chapter 13). However, chapter 14 (NFPA 13 - 2010) refers storage 12 ft and under back to Chapter 13. Section 12.1.2, which restricts roof slope to less than 2:12, states only references Chapters 12 and 14-20. I have 2 questions:
1) If I am using chapter 14 to determine criteria and it refers back to Chapter 13, does section 12.1.2 apply? 2) Does this mean that miscellaneous storage can be protected using Chapter 13 criteria without regard to roof slope? So if I have someone who wants to store to 16 ft in a building with a 4:12 pitch, a legitimate option would be to lower the storage to 12 ft? Todd G.
