# Dip Tank: Building Code Definition > How the IFC 2009 define dip tank, where the wording differs, and which chapters depend on the term. - Canonical: https://harth.build/resources/glossary/dip-tank/ - 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.

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 | 7 (counted across the codes hosted here) | | Wording identical across codes | Single code (compare before citing one code's wording under another) | ## Direct answer Dip tank is a defined term in the International Fire Code (IFC) 2009, in Flammable Finishes. The code's own words are: “A tank, vat or container of flammable or combustible liquid in which articles or materials are immersed for the purpose of coating, finishing, treating and similar processes.” 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 7 chapters of this corpus, most often in Flammable Finishes (IFC 2009), Fire Protection Systems (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. 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? **Dip Tank** — IFC 2009, Flammable Finishes: > A tank, vat or container of flammable or combustible liquid in which articles or materials are immersed for the purpose of coating, finishing, treating and similar processes. ![Labeled code-term definition diagram: Dip Tank: Building Code Definition](https://efwwel0vyt9vy5so.public.blob.vercel-storage.com/images/glossary/dip-tank/diagram-1344.webp) *How the IFC 2009 define dip tank, where the wording differs, and which chapters depend on the term.* ## What must be verified before using this guidance? **Dip Tank** 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: > A tank, vat or container of flammable or combustible liquid in which articles or materials are immersed for the purpose of coating, finishing, treating and similar processes. ## Where dip tank is used in the code The term appears in 7 chapters of the 2009 I-Codes hosted here.

Each carries its own code definition, and a local amendment to any of them changes what dip tank 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). - **[Container](https://harth.build/resources/glossary/container.md)** — IFC 2009: A vessel of 60 gallons (227 L) or less in capacity used for transporting or storing hazardous materials. - **[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). ## Dip Tank: 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: “A tank, vat or container of flammable or combustible liquid in which articles or materials are immersed for the purpose of coating, finishing, treating and similar processes.” 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 dip tank? In this corpus the term is used across 7 chapters, led by Flammable Finishes 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 a dip tank? In the 2009 I-Codes hosted here it is a defined term rather than a description. The IFC 2009 states, in Flammable Finishes: “A tank, vat or container of flammable or combustible liquid in which articles or materials are immersed for the purpose of coating, finishing, treating and similar processes.” 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. --- - Continue in Harth (open this topic in the Harth agent): https://app.harth.build/agent?context=%2Fresources%2Fglossary%2Fdip-tank%2F - View this page in a browser: https://harth.build/resources/glossary/dip-tank/ - All resources for agents: https://harth.build/llms.txt
