CHAPTER 32

HIGH-PILED COMBUSTIBLE STORAGE

User note:
About this chapter: Chapter 32 provides guidance for reasonable protection of life from hazards associated with the storage of combustible
materials in closely packed piles or on pallets, in racks or on shelves where the top of storage is greater than 12 feet in height, or 6 feet for
high-hazard commodities. It provides requirements for identifying various classes of commodities; and general fire and life safety features
including storage arrangements, smoke and heat venting, fire department access and housekeeping and maintenance. This chapter attempts
to define the potential fire severity and, in turn, determine fire and life safety protection measures needed to control and in some cases sup-
press a potential fire. This chapter does not cover miscellaneous combustible material storage as regulated in Section 315.
