Emergency Vehicle Technician (EVT) F-2 Practice Exam

The ability to pump water while the vehicle is moving is known as?

Ramp breakover angle Pump and roll Pressure governor Pumper

Correct Answer:

Pump and roll

Explanation:

The ability to pump water while the vehicle is moving is called pump and roll. This technique lets you begin delivering water and suppress a fire while the apparatus is still in motion, which can save time and help you advance a line without stopping. It requires the pump to stay primed and the suction to remain submerged, plus careful coordination of speed, steering, and nozzle control to maintain a safe, effective spray as you travel. The other terms refer to different things: ramp breakover angle is about clearance when loading or unloading, a pressure governor is a device that limits discharge pressure, and pumper is the vehicle equipped with the pump, not the action of pumping on the move.
