what are you looking for?
When Starting a pallet racking system project, sometimes the clients will ask,” should i get a high pile storage permit?” If your racking size higher than 12ft /3.5m, you should get it. For the height limited in 12 ft, you needn’t high-piled storage permit.
High-pile storage dominates modern warehousing, where maximizing vertical space drives efficiency and stacking goods safely while meeting fire codes. In this post, we will discover the high piled storage define and how to choose a right racking system for safe storage.
Key Takeaways
What is High Pile Storage and permit?
High pile storage refers to stacking combustible materials in piles, on pallets, racks, or shelves where the top exceeds 12 feet in height. For high-hazard commodities, such as expanded plastics or rubber tires, the threshold drops to 6 feet. This method optimizes warehouse space amid rising e-commerce demands, but it amplifies fire risks due to denser fuel loads.
And then, high pile storage permit (also called a high-piled combustible storage permit or operational permit for high-piled storage) is an official authorization from local fire authorities or building departments. It allows a warehouse, distribution center, or facility to operate with high-piled combustible storage setups that meet fire safety standards.
Why High Pile Storage Matters
High pile storage boosts efficiency in tight spaces, yet it amplifies fire risks. the important of high pile storage includes Compliance and Regulatory Requirements and Risks of Non-Compliance.
Compliance and Regulatory Requirements
Regulations stem from IFC Chapter 32 and NFPA 13, mandating sprinklers, smoke vents, and emergency exits. For rack storage over 12 feet, early suppression fast-response (ESFR) sprinklers activate at high temperatures, covering up to 100 square feet per head. Aisle widths must hit 4 feet minimum, with pile dimensions limited to prevent overload—e.g., no more than 20 feet high without in-rack sprinklers.
Risks of Non-Compliance
Ignoring codes leads to fines up to $10,000 per violation, shutdowns, or insurance denials. Fires in non-compliant setups spread in minutes, overwhelming sprinklers.
Various systems suit different operations, all requiring fire code adherence when heights exceed thresholds. Focus falls on pallet racking for its versatility.
Pallet Racking System Selective pallet racking allows direct access to each pallet, ideal for varied inventory. Uprights often measure 42 inches deep, with beams 96-144 inches long, supporting 5,000 pounds per level. For high pile, add wire decking to enhance sprinkler flow.
Drive-in Racking System This dense setup lets forklifts enter lanes, storing up to 10 pallets deep. It cuts aisles but demands precise flue spaces—6 inches transverse—to meet NFPA 13. Suited for bulk, like food or beverages.
Cantilever Racking System Arms extend from uprights for long items like lumber. Heights reach 20 feet, but high-hazard materials need 15-foot clearances to sprinklers.
Longspan Shelving System For hand-picked goods, shelves span 4-8 feet. Less dense, but over 12 feet triggers permits.
AS/RS System Automated storage and retrieval uses cranes for ultra-high piles up to 100 feet. Integrates sensors for fire detection, complying with IFC via redundant suppression.
Multi-tier Mezzanine Platform Adds floors for manual access, effectively doubling space. Fire walls separate tiers if storage qualifies as high pile.
| Type | Key Features | Max Height (Typical) | Best Hazard Class | Fire Protection Need |
|---|---|---|---|---|
| Pallet Racking | Selective access, adjustable beams | 24 ft | I-IV | ESFR sprinklers, 4-ft aisles |
| Drive-in | High density, deep lanes | 30 ft | II-III | In-rack sprinklers for >20 ft |
| Cantilever | For long loads, open arms | 20 ft | I-II | Clear flue spaces |
| Longspan Shelving | Manual picking, modular | 15 ft | I-III | Standard sprinklers |
| AS/RS | Automated, tall stacks | 100 ft | All | Integrated detection |
| Mezzanine | Multi-level, walkable | 20 ft per tier | I-IV | Fire-rated separations |
