Groups are designated by

Groups are designated by

• A. Function (vent group, EMS group, water supply)
• B. Geographic area
• C. Time period
• D. Incident type

Answer: (A)

Groups are designated by function—the specific tasks they perform. In incident command, a group is organized around a particular operational purpose, such as ventilation (Vent Group), medical care (EMS Group), or securing water supply (Water Supply Group). This functional design keeps work organized across the incident and makes accountability and coordination clearer, especially when multiple functions run simultaneously. Divisions would be used to separate work by geographic area (for example, north versus south sides of a building), not by function. Time period or incident type aren’t the standard criteria for forming groups, so they don’t define how groups are designated. If a fire scene requires separate efforts for ventilation, medical care, and water supply, naming groups by their function helps everyone understand who is responsible for which part of the operation.
