What is the typical spray distance of a stored-pressure water extinguisher?

The typical spray distance of a stored-pressure water extinguisher is indeed about 30 feet to 40 feet. This distance is significant because it allows the firefighter using the extinguisher to maintain a safe distance from the fire while effectively discharging water to suppress it. The ability to spray water from this range is especially important in preventing the fire from spreading and for the safety of the individual operating the extinguisher.

Stored-pressure water extinguishers use the pressure of the stored water to propel the water stream, and the design of these extinguishers typically enables them to project water effectively up to the stated distance. This aspect of their operation is crucial for managing smaller fires, particularly those involving ordinary combustibles, and enhances the user's ability to stay safe while addressing fire hazards. Knowing that the range falls within this distance helps in making informed decisions regarding fire control approaches and equipment selection.
