## Key facts

| Fact | Value |
| --- | --- |
| Defined in | IFC 2009 (2009 editions transcribed in this corpus) |
| Primary source | IFC 2009 Explosives and Fireworks (model text, not a jurisdiction's adopted text) |
| Chapters using the term | 9 (counted across the codes hosted here) |
| Wording identical across codes | Single code (compare before citing one code's wording under another) |

## Direct answer

Explosive material is a defined term in the International Fire Code (IFC) 2009, in Explosives and Fireworks. The code's own words are: “The term "explosive" material means explosives, blasting agents and detonators.” No other I-Code in this corpus defines it, so the IFC 2009 definition is the one to work from. The term is used in 9 chapters of this corpus, most often in Explosives and Fireworks (IFC 2009), Use and Occupancy Classification (IBC 2009), Hazardous Materials-general Provisions (IFC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. Record the jurisdiction, the adopted edition, the application date and any local amendment that rewrites the definition before you use it on a live project, because a term redefined by amendment changes every requirement that depends on it.

### The term in use

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

> The net weight of the explosive material shall be used.

— [IFC 2009 §3301.8.1.4](https://harth.build/resources/building-codes/us-states/rhode-island/ifc-2009/explosives-and-fireworks.md)

> A person shall not take or utilize an open flame or light in a structure, vessel, boat or other place where highly flammable, combustible or explosive material is utilized or stored.

— [IFC 2009 §308.1.1](https://harth.build/resources/building-codes/us-states/rhode-island/ifc-2009/general-requirements.md)


## The terms explosive material is built out of

The definition above leans on 1 other defined term. Each carries its own code definition, and a local amendment to any of them changes what explosive material covers:

- **[Explosive](https://harth.build/resources/glossary/explosive.md)** — IBC 2009: A chemical compound, mixture or device, the primary or common purpose of which is to function by explosion.

## Explosive Material: what to open, and in what order

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.

| Check | Where | Confirmed |
| --- | --- | --- |
| Read the definition in the adopted IFC | Explosives and Fireworks | |
| Re-check the requirement that uses it | Explosives and Fireworks (IFC 2009) | |
| Re-check the requirement that uses it | Use and Occupancy Classification (IBC 2009) | |
| Re-check the requirement that uses it | Hazardous Materials-general Provisions (IFC 2009) | |
| Re-check the requirement that uses it | Fire Safety During Construction and Demolition (IFC 2009) | |
| Confirm the dependent definition | Explosive | |
| Local amendment to any of the above | Jurisdiction's amendment list | |

**A research aid, not a code determination.** The authority having jurisdiction decides which edition and which amendments apply.

## Frequently asked questions

### What is the code definition of explosive material?

The International Fire Code (IFC) 2009 defines it in Explosives and Fireworks as: “The term "explosive" material means explosives, blasting agents and detonators.” 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 explosive material?

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 meaning of explosive material?

In the 2009 I-Codes hosted here it is a defined term rather than a description. The IFC 2009 states, in Explosives and Fireworks: “The term "explosive" material means explosives, blasting agents and detonators.” It is defined in 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.
