Fire streams that deliver less than _____ gallons per minute are considered to be handlines.

Fire streams that deliver less than 350 gallons per minute (GPM) are classified as handlines. Handlines are typically utilized for smaller fires where more precise control over the application of water is necessary, and they can be managed by one or two firefighters. The 350 GPM threshold is established so that fire crews can effectively handle these smaller streams to produce quick tactics and perform in more confined spaces, thus maintaining better maneuverability and accuracy.

Additionally, larger streams, referred to as master streams, generally exceed the 350 GPM threshold, as they are designed for attacking larger fires or supporting a greater volume of fire activity. This distinction helps ensure that firefighters use the most appropriate tools and techniques for different fire scenarios, optimizing their effectiveness and safety.
