What is the flow range of a master stream used in firefighting?

The flow range of a master stream used in firefighting typically spans from 350 to 1500 gallons per minute (gpm). Master streams are utilized in situations requiring a significant volume of water, such as large structure fires or major outdoor fires, where effective suppression is crucial. This range allows firefighters to adequately combat intense fires, providing the necessary water flow to cool and extinguish flames efficiently while also protecting surrounding structures and ensuring the safety of personnel on the scene.

In contrast, the other options present flow rates that are either too low or not sufficient for the demanding situations where master streams are used. A flow range of 100 to 500 gpm is more suited for handlines and smaller operations, while 50 to 250 gpm and 200 to 800 gpm do not meet the high water demand required for effective operation of master streams. Thus, a flow rate between 350 to 1500 gpm is essential for achieving successful fire suppression with these powerful firefighting tools.
