Master streams typically flow how much water?

  1. 200 GPM

  2. 350 GPM

  3. 500 GPM

  4. 1000 GPM

The correct answer is: 350 GPM

Master streams are typically high-capacity water delivery systems used in firefighting, especially for combating large-scale or intense fires. The correct flow rate for master streams generally ranges around 350 gallons per minute (GPM). This flow rate allows for a significant volume of water to be delivered quickly, which is essential for effective suppression of fires that may exceed the capabilities of portable or hand-held lines. The 350 GPM flow rate strikes a balance between manageable pressure and effective water delivery, making it a standard choice for many fire departments. Master streams are often employed through apparatuses like ladder trucks or large ground monitors, providing firefighters the ability to attack a fire from a distance or from an elevated position safely. While the other options reflect different flow rates, they either exceed the common usage for master streams or do not align with standard operational protocols in many fire departments, which typically utilize around 350 GPM for efficient firefighting operations.
