## Key facts

| Fact | Value |
| --- | --- |
| Defined in | IBC 2009, IFC 2009 (2009 editions transcribed in this corpus) |
| Primary source | IBC 2009 Use and Occupancy Classification (model text, not a jurisdiction's adopted text) |
| Chapters using the term | 9 (counted across the codes hosted here) |
| Wording identical across codes | No (compare before citing one code's wording under another) |

## Direct answer

Fireworks is a defined term in the International Building Code (IBC) 2009, in Use and Occupancy Classification. The code's own words are: “Any composition or device for the purpose of producing a visible or audible effect for entertainment purposes by combustion, deflagration or detonation that meets the definition of 1.4G fireworks or 1.3G fireworks as set forth herein.” The IFC 2009 defines the same term with different wording, so the controlling text depends on which code governs the question in front of you — the comparison below sets the versions side by side. The term is used in 9 chapters of this corpus, most often in Explosives and Fireworks (IFC 2009), Use and Occupancy Classification (IBC 2009), Definitions (IFC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.

## What must be verified before using this guidance?

Two of the I-Codes in this corpus define **Fireworks**, and the wording is not identical — read the version that governs your question.

### The term in use

How the code actually writes about fireworks, quoted from the 2009 text hosted here:

> The provisions of this chapter shall govern the possession, manufacture, storage, handling, sale and use of explosives, explosive materials, fireworks and small arms ammunition.

— [IFC 2009 §3301.1](https://harth.build/resources/building-codes/us-states/rhode-island/ifc-2009/explosives-and-fireworks.md)

> An operational permit is required for the manufacture, storage, handling, sale or use of any quantity of explosives, explosive materials, fireworks or pyrotechnic special effects within the scope of Chapter 33.

— [IFC 2009 §105.6.14](https://harth.build/resources/building-codes/us-states/rhode-island/ifc-2009/scope-and-administration.md)

> Fireworks shall not be used within 100 feet (30 480 mm) of tents or membrane structures.

— [IFC 2009 §2404.8](https://harth.build/resources/building-codes/us-states/rhode-island/ifc-2009/tents-and-other-membrane-structures.md)


## The terms fireworks is built out of

The definition above leans on 4 other defined terms. Each carries its own code definition, and a local amendment to any of them changes what fireworks covers:

- **[Deflagration](https://harth.build/resources/glossary/deflagration.md)** — IBC 2009: An exothermic reaction, such as the extremely rapid oxidation of a flammable dust or vapor in air, in which the reaction progresses through the unburned material at a rate less than the velocity of sound.
- **[Combustion](https://harth.build/resources/glossary/combustion.md)** — IRC 2009: In the context of this code, refers to the rapid oxidation of fuel accompanied by the production of heat or heat and light.
- **[Detonation](https://harth.build/resources/glossary/detonation.md)** — IBC 2009: An exothermic reaction characterized by the presence of a shock wave in the material which establishes and maintains the reaction.
- **[Device](https://harth.build/resources/glossary/device.md)** — IRC 2009: Aunit of an electrical system that carries or controls electrical energy as it principal function.

Every row is a document this term depends on. The [ICC code library](https://codes.iccsafe.org/codes) and the [ICC adoption maps](https://www.iccsafe.org/advocacy/code-adoption-maps/) cover the middle rows.

## Frequently asked questions

### What is the code definition of fireworks?

The International Building Code (IBC) 2009 defines it in Use and Occupancy Classification as: “Any composition or device for the purpose of producing a visible or audible effect for entertainment purposes by combustion, deflagration or detonation that meets the definition of 1.4G fireworks or 1.3G fireworks as set forth herein.” The 2009 model text is reproduced here; the definition that binds your project is the one in the edition your jurisdiction has adopted, as amended locally.

### Which parts of the code depend on fireworks?

In this corpus the term is used across 9 chapters, led by Explosives and Fireworks in the IFC 2009. Those are the sections whose scope moves if the definition is amended locally, so read them together with Chapter 2 rather than on their own.

### What is the fireworks code?

In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in Use and Occupancy Classification: “Any composition or device for the purpose of producing a visible or audible effect for entertainment purposes by combustion, deflagration or detonation that meets the definition of 1.4G fireworks or 1.3G fireworks as set forth herein.” It is defined in IBC 2009, IFC 2009. Because it is a defined term, whatever the adopted edition says it means is what every section using it means — so check Chapter 2 of that edition and any local amendment before relying on this wording.
