A fire extinguishing system for a rack warehouse was recently designed, which only consider the gross area and number of stories. However, the design of such a system should take into account not only the planar structuree, but also the elevation perspectives due to its vertical structure. Moreover, the fire load of the commodities palletized on the racks should be considered, in order to design a performance-based fire safety system that is appropriate for these environmental conditions. For this reason, this study analyzed the fire characteristics of the commodities palletized on the racks (pallet + the commodities in a box unit + vinyl packing material), taking into consideration the results of a field investigation conducted in Korea, as well as the Hazard Classifications of Commodities used in other countries. Through this analysis, the heat release rate (HRR) and smoke production rate (SPR) were derived.
