How much water do master stream nozzles typically handle?

Master stream nozzles are designed to deliver large volumes of water, making them essential for fighting large-scale fires, such as those found in commercial structures or wildland fires. They are typically capable of handling flows of more than 350 gallons per minute (gpm). This high flow rate is crucial when dealing with significant fire loads where a substantial amount of water is needed to effectively suppress the fire.

The ability to manage high volumes of water gives firefighters the necessary tools to combat and control large or rapidly spreading fires. Master stream nozzles are often used in conjunction with large diameter hose lines and it is important for crews to understand that these nozzles are specifically engineered for such high-flow applications. This capacity differentiates them from smaller handline nozzles, which usually operate at lower flow rates. Understanding the capabilities of master stream nozzles aids firefighters in making strategic decisions about deploying adequate water resources during an incident.
