Fire Protection Engineering
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
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

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
8
Fire Protection Engineering
Proposed Testing Concept – Full Scale Testing
Storage Configurations– Rack storage array– Palletized array
9
Retail Configurations– Shelf storage arrays– Palletized arrays– Influence of projectiles– Influence of spark spray

Description of Test Product Type Number of Tests
Mock Building Construction of 3,000-5,000 ft2 mock building To be used in all full scale tests
Calorimeter –Fuel Package Tests
Samples from categories defined by NFPA 1124, Appendix C
12 - One from each category plus three more
Full scale retail tests (described in Table 1)
Highest heat-release rate products, plus worst case projectile launching products
6 - gondola array,2 - palletized array
Full scale storage tests Highest heat-release rate products in DOT approved packaging
1 - rack storage, 1 - palletized array
