Direct answer
Workstation is a defined term in the International Building Code (IBC) 2009, in Special Detailed Requirements Based on Use and Occupancy. The code's own words are: “A defined space or an independent principal piece of equipment using HPM within a fabrication area where a specific function, laboratory procedure or research activity occurs. Approved or listed hazardous materials storage cabinets, flammable liquid storage cabinets or gas cabinets serving a workstation are included as part of the workstation. A workstation is allowed to …” 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 6 chapters of this corpus, most often in Semiconductor Fabrication Facilities (IFC 2009), Special Detailed Requirements Based on Use and Occupancy (IBC 2009), Explosives and Fireworks (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?
Workstation — IBC 2009, Special Detailed Requirements Based on Use and Occupancy:
A defined space or an independent principal piece of equipment using HPM within a fabrication area where a specific function, laboratory procedure or research activity occurs. Approved or listed hazardous materials storage cabinets, flammable liquid storage cabinets or gas cabinets serving a workstation are included as part of the workstation. A workstation is allowed to contain ventilation equipment, fire protection devices, detection devices, electrical devices and other processing and scientific equipment.

The term in use
How the code actually writes about workstation, quoted from the 2009 text hosted here:
Storage of HPM in fabrication areas shall be within approved or listed storage cabinets, gas cabinets, exhausted enclosures or within a workstation as follows.
Two or more operations at a workstation shall not be connected to the same exhaust system where either one or the combination of the substances removed could constitute a fire, explosion or hazardous chemical reaction within the exhaust duct system.

The terms workstation is built out of
The definition above leans on 5 other defined terms. Each carries its own code definition, and a local amendment to any of them changes what workstation covers:
- Hazardous Materials — IBC 2009: Those chemicals or substances that are physical hazards or health hazards as defined and classified in this section and the International Fire Code, whether the materials are in usable or waste condition.
- Flammable Liquid — IBC 2009: A liquid having a closed cup flash point below 100°F (38°C).
- Fabrication Area — IBC 2009: An area within a semiconductor fabrication facility and related research and development areas in which there are processes using hazardous production materials.
- Ventilation — IBC 2009: The natural or mechanical process of supplying conditioned or unconditioned air to, or removing such air from, any space.
- Equipment — IRC 2009: All piping, ducts, vents, control devices and other components of systems other than appliances that are permanently installed and integrated to provide control of environmental conditions for buildings.

Frequently asked questions
What is the code definition of workstation?
The International Building Code (IBC) 2009 defines it in Special Detailed Requirements Based on Use and Occupancy as: “A defined space or an independent principal piece of equipment using HPM within a fabrication area where a specific function, laboratory procedure or research activity occurs. Approved or listed hazardous materials storage cabinets, flammable liquid storage cabinets or gas cabinets serving a workstation are included as part of the workstation. A workstation is allowed to contain ventilation equipment, fire protection devices, detection devices, electrical devices and other processing and scientific equipment.” 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 workstation?
In this corpus the term is used across 6 chapters, led by Semiconductor Fabrication Facilities 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 does IBC mean in building codes?
Building is a separate defined term. The IBC 2009 defines it as: “Any structure used or intended for supporting or sheltering any use or occupancy.” That is not the same as workstation, which the IBC 2009 defines as “A defined space or an independent principal piece of equipment using HPM within a fabrication area where a specific function, laboratory procedure or research activity occurs. Approved or listed hazardous materials storage cabinets, flammable liquid storage cabinets or gas cabinets …” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
What do we mean by workstation?
In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in Special Detailed Requirements Based on Use and Occupancy: “A defined space or an independent principal piece of equipment using HPM within a fabrication area where a specific function, laboratory procedure or research activity occurs. Approved or listed hazardous materials storage cabinets, flammable liquid storage cabinets or gas cabinets serving a workstation are included as part of the workstation. A workstation is allowed to …” 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.
