What is the maximum distance between the foam educator and nozzle?

The maximum distance between the foam educator and the nozzle is established to ensure that the foam concentrate is properly mixed with water and delivered effectively to the fire scene. A distance of 200 feet is typically specified as the standard limit, which allows for optimal performance, maintaining sufficient pressure and ensuring the quality of the foam. This distance is crucial for allowing the foam to maintain its effectiveness, as too far a separation can result in dilution or improper mixing, which compromises the foam's ability to suppress fire.

In practice, staying within this distance helps firefighters ensure that the foam is consistently produced at the correct concentration and then applied to the burning material, maximizing the firefighting capabilities offered by foam systems. The other distances listed exceed the recommended parameter and could lead to reduced effectiveness of foam firefighting efforts.
