Which position is described as having final line of responsibility and authority?

• A. Chief Officer
• B. Deputy Chief
• C. Captain
• D. Lieutenant

Answer: (A)

At the top of the command structure, the person with final line of responsibility and authority is the Chief Officer. This role holds ultimate accountability for the entire department and for decisions that affect safety, policy compliance, mission success, and how resources are allocated across incidents. The Chief Officer sets the direction, approves major actions, and bears the final responsibility for outcomes.

The Deputy Chief supports and acts in the Chief Officer’s absence, stepping in to lead when needed, but the ultimate authority remains with the Chief Officer. Captains and Lieutenants are first-line supervisors who manage specific units and tasks on scene, ensuring work gets done within their span of control, yet they do not hold final authority over the entire incident or department.
