Which component of a fire stream is responsible for delivering the extinguishing agent?

• A. Pump
• B. Hose
• C. Nozzle
• D. Water/Agent

Answer: (D)

The element doing the work in a fire stream is the extinguishing medium itself—the water or water/agent mixture that actually contacts the fire. The job of delivering that medium to the flame is carried by the stream as it leaves the nozzle, so the component that delivers the extinguishing effect is the water/agent being discharged. The pump provides the pressure, the hose transports it, and the nozzle shapes and controls the flow, but the substance reaching and acting on the fire is the water or water/agent.
