Unified Command

What Is Unified Command?

Unified Command is an NIMS ICS structure used during multi-jurisdictional or multi-agency incidents where designated leaders from fire, police, EMS, and environmental agencies co-locate at a single Command Post to establish shared objectives and a single Incident Action Plan.

Why Unified Command Matters on the Fireground

Complex calls like active shooter events or hazmat spills involve overlapping agency authority. Unified Command prevents conflicting orders (e.g., police advancing while fire evacuates) by consolidating decision-making.

Relevant NFPA Standards
