When does the water stop spraying from a stored-pressure water extinguisher?

The water stops spraying from a stored-pressure water extinguisher when the shut-off device is pressed or when the tank is empty. This mechanism is designed for safety and control; the shut-off device allows the user to stop the flow of water when it is no longer needed or when a specific area has been effectively targeted. Additionally, once the tank is empty, there is no longer any pressurized water available to expel, thereby ceasing the spraying action.

The design of these extinguishers emphasizes user control and safety during operation, allowing firefighters or individuals using the extinguisher to efficiently manage their resources while ensuring the fire is adequately addressed. Understanding this operational feature helps users maximize the effectiveness of the extinguisher and apply it correctly to extinguish fires.
