A nozzle delivering up to 350 gpm is typically classified as which type?

• A. Master Stream
• B. Low-Volume
• C. High-Volume
• D. Handline

Answer: (D)

Flows and how the nozzle is used on scene determine the classification. A nozzle that delivers up to about 350 gpm is considered a handline because it stays within the range that a firefighter can maneuver with a smaller attack hose (like 1¾" or 2"). Handline operations focus on interior fire attack and quick, controlled application, so the flow remains manageable for one or two people. Master stream nozzles, by contrast, produce much higher flows, require larger hose lines, and are used from standpipes, decks guns, or monitors to reach and contain larger fires from a distance. Low-volume would imply even smaller flows than typical handlines, and high-volume would imply flows well above 350 gpm. Therefore, 350 gpm or less is best classified as a handline.
