What term refers to a fire truck specially equipped to pump water at the site of a fire?

• A. Preservice test
• B. Relay Pumping
• C. Pumper
• D. Pressure relief device

Answer: (C)

A fire truck specialized to pump water at the scene is a pumper. Its defining feature is a built-in pump, a water tank, and hoses that let it move water directly to the fire, drawing from a hydrant, another source, or its own tank. This distinguishes it from other apparatus types: a preservice test is simply checking equipment before it goes into service, a pressure relief device is a pump safety valve, and relay pumping is a method of pushing water through multiple pumpers to reach a distant fire. The pumper’s role is to actively deliver water to the fire, which is why this term is the correct one.
