BLS Engine minimum staffing is:

• A. One (1) Company Officer, one (1) Apparatus Operator, and two (2) Firefighters.
• B. One (1) Company Officer, one (1) Apparatus Operator, and one (1) Paramedic.
• C. One (1) Company Officer, one (1) Apparatus Operator, and one (1) Firefighter.
• D. One (1) Company Officer, one (1) Apparatus Operator, and three (3) Firefighters.

Answer: (C)

Minimum staffing for a BLS engine is three people: one Company Officer, one Apparatus Operator, and one Firefighter. The Company Officer commands the scene and assigns tasks, the Apparatus Operator (engine driver) handles driving and pump operations, and the Firefighter provides initial fire suppression and supports hose layout and basic operations. A Paramedic is an ALS role and not required for BLS minimum staffing on the engine, so including a paramedic instead of a firefighter would not meet this minimum. Staffing more than three people increases crew size beyond the minimum, which is why the three-person combination is the best choice.
