What is a common flow rate for handline nozzles?

The common flow rate for handline nozzles typically falls within the range of 40 to 60 gallons per minute (gpm). This flow rate is considered adequate for effective fire suppression while still being manageable for firefighters to handle the hose and nozzle. Handline nozzles are designed to provide sufficient water pressure and volume to combat fires in a variety of scenarios, such as structural fires or wildland firefighting.

In terms of operational efficiency, the 40 to 60 gpm range strikes a balance between delivering enough water to suppress flames effectively and allowing for a maneuverable firefighting approach. Firefighters can easily operate this flow rate with a team, as it prevents fatigue and allows for swift movement to coordinate attacks on fire hotspots. Adjustments can be made based on the specific fire conditions, but this range is a standard in many departments for handline operations. The other provided flow ranges either exceed typical handheld capabilities or are not as commonly used for basic firefighting operations.
