Water spray fire extinguishers

They are suitable to take out fires that involve organic solid materials like wood, paper, plastic, or coal. They cannot be used on oil or electrical appliances. The jet is pointed at the base of the flame and is moved around constantly until the fire is extinguished. A jet nozzle is avoided in favor of a spray nozzle, thereby creating a fine spray at a higher pressure. Furthermore, it hits a wider surface area which subdues the heat more instantly. Additionally, additives can be added to help the water penetrate further into the burning material.
