# Flammable Finishes: Building Code Definition > How the IFC 2009 define flammable finishes, where the wording differs, and which chapters depend on the term. - Canonical: https://harth.build/resources/glossary/flammable-finishes/ - Last updated: 2026-09-07 - Data source: Definitions quoted from the 2009 International Codes as transcribed in this site's building-codes collection, with the source chapter linked for each quotation. Usage counts are computed over the chapters hosted here, one copy per code. The [ICC code library](https://codes.iccsafe.org/codes) publishes the current model text and the [ICC adoption maps](https://www.iccsafe.org/advocacy/code-adoption-maps/) show which edition a jurisdiction has adopted; those sources control. ## Key facts | Fact | Value | | --- | --- | | Defined in | IFC 2009 (2009 editions transcribed in this corpus) | | Primary source | IFC 2009 Flammable Finishes (model text, not a jurisdiction's adopted text) | | Chapters using the term | 6 (counted across the codes hosted here) | | Wording identical across codes | Single code (compare before citing one code's wording under another) | ## Direct answer Flammable finishes is a defined term in the International Fire Code (IFC) 2009, in Flammable Finishes. The code's own words are: “Material coatings in which the material being applied is a flammable liquid, combustible liquid, combustible powder or flammable or combustible gel coating.” 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 6 chapters of this corpus, most often in Definitions (IFC 2009), Flammable Finishes (IFC 2009), Special Detailed Requirements Based on Use and Occupancy (IBC 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. *Content and cited inputs reviewed by [Scott Barrington](https://nz.linkedin.com/in/barrington), Harth founder and architectural technology specialist · Published 2026-09-07 · Updated 2026-09-07.* ## What does this term mean? **Flammable Finishes** — IFC 2009, Flammable Finishes: > Material coatings in which the material being applied is a flammable liquid, combustible liquid, combustible powder or flammable or combustible gel coating. ![Labeled code-term definition diagram: Flammable Finishes: Building Code Definition](https://efwwel0vyt9vy5so.public.blob.vercel-storage.com/images/glossary/flammable-finishes/diagram-1344.webp) *How the IFC 2009 define flammable finishes, where the wording differs, and which chapters depend on the term.* ## What must be verified before using this guidance? **Flammable Finishes** is defined once in this corpus, in the [Flammable Finishes](https://harth.build/resources/building-codes/us-states/rhode-island/ifc-2009/flammable-finishes.md) chapter of the International Fire Code (IFC) 2009: > Material coatings in which the material being applied is a flammable liquid, combustible liquid, combustible powder or flammable or combustible gel coating. ## Where flammable finishes is used in the code The term appears in 6 chapters of the 2009 I-Codes hosted here.

Each carries its own code definition, and a local amendment to any of them changes what flammable finishes covers: - **[Combustible Liquid](https://harth.build/resources/glossary/combustible-liquid.md)** — IBC 2009: A liquid having a closed cup flash point at or above 100°F (38°C). - **[Flammable Liquid](https://harth.build/resources/glossary/flammable-liquid.md)** — IBC 2009: A liquid having a closed cup flash point below 100°F (38°C). - **[Liquid](https://harth.build/resources/glossary/liquid.md)** — IBC 2009: A material that has a melting point that is equal to or less than 68°F (20°C) and a boiling point that is greater than 68°F (20°C) at 14.7 pounds per square inch absolute (psia) (101 kPa). ## Flammable Finishes: what to open, and in what order Every row is a document this term depends on.

The International Fire Code (IFC) 2009 defines it in Flammable Finishes as: “Material coatings in which the material being applied is a flammable liquid, combustible liquid, combustible powder or flammable or combustible gel coating.” 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 flammable finishes? In this corpus the term is used across 6 chapters, led by Definitions 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. --- - Continue in Harth (open this topic in the Harth agent): https://app.harth.build/agent?context=%2Fresources%2Fglossary%2Fflammable-finishes%2F - View this page in a browser: https://harth.build/resources/glossary/flammable-finishes/ - All resources for agents: https://harth.build/llms.txt
