Under Staffing and Organization, how many instructors are assigned to each back-up line?

• A. One
• B. Two
• C. None
• D. Three

Answer: (A)

Staffing and organization rely on clear supervision of each tactical component to maintain safety and effective coordination. For the back-up line, having a single instructor dedicated to overseeing that line provides direct accountability, ensures proper hose handling and readiness, and maintains real-time communication with the IIC and the attacking crew. This focused supervision helps quickly detect any issues with deployment, water supply, or firefighters’ conditions, and allows the instructor to intervene as needed without competing with multiple supervisors. Assigning more than one instructor can create confusion or split attention, while having none leaves the back-up line without essential oversight. Three instructors would be unnecessary and could complicate command and control. Therefore, one instructor per back-up line best supports safe, organized operation.
