Fire Protection Engineering
FPRF Sprinkler Protection Criteria for Consumer
Fireworks Storage in Retail Facilities
Garner Palenske, P.E.
AON FPE Vice President | US Western Region
Overview
This study had two primary objectives:
 To conduct/oversee a field survey of the
configurations of fireworks storage in retail facilities
to develop a design basis for hazard assessment
 To develop a research plan with associated
preliminary cost estimate to evaluate required
sprinkler design criteria for consumer fireworks
storage in these facilities

Field Survey Findings – Retail Areas
 Similar to Grocery Stores
– Layout
– Product distribution
– Organization
 Displayed in Original Packaging
 Removal of Damaged Products

Fire Protection Engineering
Field Survey Findings – Retail Areas
 Fuse Covers / Protective Packaging
 Shelving Sizes & Types Varied
– Gondolas (up to 5 shelves)
– Pallets
– Single level bins
 Storage Heights & Lengths Varied
– Most shelving ≤ 72 inches tall
– All shelving ≤ 32 feet long

Fire Protection Engineering
Field Survey Findings – Storage Areas
 Storage Protection
– Sprinkler System
– Building Separation
 DOT Approved Packaging
 Shelving Sizes & Types Varied
– Predominant Method: Solid Pile
– Rack Storage in Five Stores
 Storage Heights Varied
– 120 Inches for Solid Pile
– 166 Inches for Racks

Fire Protection Engineering
Proposed Testing Concept – Reduced Scale Testing
 Use Calorimeter Testing
 Address Fireworks Characteristics
– Energy release from fire
– Deflagration potential
– Spark spray
– Launching projectiles
 Determine Worst Case Products
– Baseline for full scale testing

Fire Protection Engineering
Proposed Testing Concept – Full Scale Testing
 Retail Configurations
– Shelf storage arrays
– Palletized arrays
– Influence of projectiles
– Influence of spark spray
 Storage Configurations
– Rack storage array
– Palletized array
