## 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 | 2 (counted across the codes hosted here) |
| Wording identical across codes | Single code (compare before citing one code's wording under another) |

## Direct answer

Electrostatic fluidized bed is a defined term in the International Fire Code (IFC) 2009, in Flammable Finishes. The code's own words are: “A container holding powder coating material that is aerated from below so as to form an air-supported expanded cloud of such material that is electrically charged with a charge opposite to that of the object to be coated. Such object is transported through the container immediately above the charged and aerated materials in order to …” 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 2 chapters of this corpus, most often in Flammable Finishes (IFC 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 does this term mean?

**Electrostatic Fluidized Bed** — IFC 2009, Flammable Finishes:

> A container holding powder coating material that is aerated from below so as to form an air-supported expanded cloud of such material that is electrically charged with a charge opposite to that of the object to be coated. Such object is transported through the container immediately above the charged and aerated materials in order to be coated.

## What must be verified before using this guidance?

**Electrostatic Fluidized Bed** 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 container holding powder coating material that is aerated from below so as to form an air-supported expanded cloud of such material that is electrically charged with a charge opposite to that of the object to be coated. Such object is transported through the container immediately above the charged and aerated materials in order to be coated.

### The term in use

How the code actually writes about electrostatic fluidized bed, quoted from the 2009 text hosted here:

> Operations using finely ground particles of protective finishing material applied in dry powder form by a fluidized bed, an electrostatic fluidized bed, powder spray guns or electrostatic powder spray guns shall comply with this section.

— [IFC 2009 §1506.1](https://harth.build/resources/building-codes/us-states/rhode-island/ifc-2009/flammable-finishes.md)


## The terms electrostatic fluidized bed 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 electrostatic fluidized bed covers:

- **[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.

## Electrostatic Fluidized Bed: 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 | Flammable Finishes | |
| Re-check the requirement that uses it | Flammable Finishes (IFC 2009) | |
| Re-check the requirement that uses it | Definitions (IFC 2009) | |
| Confirm the dependent definition | Container | |
| Local amendment to any of the above | Jurisdiction's amendment list | |

## Frequently asked questions

### What is the code definition of electrostatic fluidized bed?

The International Fire Code (IFC) 2009 defines it in Flammable Finishes as: “A container holding powder coating material that is aerated from below so as to form an air-supported expanded cloud of such material that is electrically charged with a charge opposite to that of the object to be coated. Such object is transported through the container immediately above the charged and aerated materials in order to be coated.” 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 electrostatic fluidized bed?

In this corpus the term is used across 2 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.
