2019 ICC Annual ConferenceEducational Sessions Handout2018 IFC High‐Piled Combustible StorageModule #1High-Piled Storage Practices10Why High-Piled? High-piled storage arrays: allow the owner or tenant to maximize amount ofgoods stored in a smaller footprint, enable rapid construction of large, low-costwarehouses near shifting population andtransportation nodes, and, increase efficiency in product handling within thestorage configuration.2018 IFC High-Piled Combustible Storage11Fire Challenges Increased fuel loads per square foot Increased potential fire loss persquare foot Rapid structural failure First responder endangerment Losses can surpass the buildingconstruction value12Copyright 2019 International Code Council4
