Which term describes the ability of an apparatus to pump water while the vehicle is in motion?

• A. Pressure governor
• B. Pump and roll
• C. Pumper
• D. Ramp breakover angle

Answer: (B)

The ability to pump water while the vehicle is moving is described by the term pump and roll. This is the practice of keeping the pump flowing while the apparatus is in motion, allowing water to reach the scene and maintain pressure without stopping to set the pump. It’s especially useful for rapid initial attack or when repositioning to maintain water flow as you advance.

Why this fits best: it directly captures the action of pumping water while the vehicle is in motion, which is not what the other terms describe.

• Pressure governor refers to the device that regulates pump pressure, not the vehicle’s movement while pumping.

• A pumper generally means the person operating the pump or the pump-equipped unit, not the act of pumping while moving.

• Ramp breakover angle concerns the vehicle’s ability to clear a ramp without striking the undercarriage, unrelated to pumping while in motion.
