A hand line stream falls into which flow range?

• A. 40-350 gpm
• B. 350-800 gpm
• C. 1000-1500 gpm
• D. 5-20 gpm

Answer: (A)

Hand line streams are used for direct attack and are designed to deliver a moderate, easily controllable flow by a single firefighter. The typical flow range for a hand line is about 40 to 350 gallons per minute, which matches common nozzle sizes and hose combinations used for handlines. This range provides enough water to advance on the fire and knock down flames while keeping the operator maneuverable. Higher ranges (350-800 gpm or more) require larger lines or master streams, not a hand line, and very low flows (5-20 gpm) wouldn’t deliver sufficient water for effective firefighting with a hand line. So, the hand line stream falls into 40-350 gpm.
