Master streams are defined as any stream flowing more than how many gallons per minute (GPM)?

Master streams are defined as high-capacity water streams that flow at rates exceeding 300 gallons per minute (GPM). This classification is important for fire suppression operations, as master streams are utilized in large-scale firefighting scenarios where significant amounts of water are required to effectively combat significant fires.

The threshold of 300 GPM allows firefighters to manage and address more intense fires, such as those found in commercial buildings or large structures. Streams at this volume ensure that there is enough water to adequately suppress flames and protect surrounding structures and lives.

Understanding this definition helps in coordinating firefighting efforts and effectively deploying resources during incidents that necessitate a more aggressive fire attack.
