Nozzles that deliver up to 350 gpm are considered:

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

Answer: (C)

Nozzle flow ranges determine how fire attack lines are categorized. When a nozzle delivers up to about 350 gpm, it’s aligned with the handline category because this is the typical capacity for standard interior attack lines that firefighters can manage with a hand on the nozzle. Handlines use smaller hose and are designed for controlled, close-quarters firefighting where immediate knockdown and quick advancement are needed. As you push beyond that flow, you move into larger streams that require bigger equipment and coordination, described as master streams or high-volume applications. So, up to 350 gpm is considered handline.
