Command Post

What Is Command Post?

The Command Post is the fixed physical location, not just a role, where the Incident Commander manages the incident using a tactical worksheet or command board, tracking resource assignments, PAR checks, and the incident action plan. It's typically marked visibly on scene (a green light, a labeled vest, or a command vehicle) so any arriving unit or mutual aid resource can find it without needing to ask over the radio. Placement matters tactically: it should have an unobstructed view of at least one side of the structure where possible, be positioned outside the collapse zone, and be located far enough from apparatus and hoselines that command isn't disrupted by pump noise or forced to relocate mid-incident. On larger incidents, the Command Post shifts from a single officer with a clipboard to a mobile command unit or a full ICS structure with a documented ICS 201 form as the incident escalates.

Why Command Post Matters on the Fireground

An unmarked or poorly placed Command Post costs time when a late-arriving company or mutual aid crew can't locate the IC to get an assignment, and a Command Post set up inside a collapse zone or too close to operations risks becoming a casualty itself. The physical setup, visible marking, safe placement, a working tactical worksheet, is what actually lets someone walk up and get accurate accountability and assignment information without pulling the IC off the radio.

Field Procedures & Tactical Steps

1. Establish and clearly mark the Command Post location as soon as command is assumed, and broadcast its location over the radio.
2. Position the Command Post outside the collapse zone with an unobstructed view of the structure where possible.
3. Maintain a tactical worksheet or command board tracking unit assignments, PAR checks, and the current incident action plan.
4. Relocate and re-announce the Command Post if the initial position becomes unsafe or loses visibility of critical operations.

Common Context & Application

Established immediately by the first-arriving officer taking command, then relocated to a fixed and clearly marked position as additional resources arrive and the incident escalates beyond initial size-up.
