Who is the person ultimately responsible for managing an incident within the IMS?

• A. Commanding Officer
• B. Incident Commander
• C. Planning Chief
• D. Operations Chief

Answer: (B)

In the Incident Management System, the person in charge on the incident scene is the Incident Commander. This role has the overall authority and responsibility for establishing incident objectives, setting priorities, and directing actions to meet those objectives while ensuring responder safety and resource accountability. The Incident Commander coordinates with the command staff and with other agencies, and if multiple agencies are involved, a Unified Command structure may be used so leaders from each agency work together to guide the incident. Other positions such as Planning Chief and Operations Chief carry out their specific functions under the Incident Commander’s direction, turning goals into actions and managing resources to keep the incident plan on track. The title Commanding Officer is not the formal incident leadership role within IMS, though it may exist in some organizations; on-scene leadership rests with the Incident Commander (or a Unified Command team) who holds the ultimate responsibility for incident management.
