A water-based fire extinguisher is a fire-extinguishing equipment that uses water as a fire-extinguishing agent. It usually consists of a pressure tank, nozzles and spray system. The pressure tank is filled with water and the internal pressure is increased by compressed air or nitrogen. When the fire extinguisher is triggered, the nozzle will release high-pressure water mist and spray the water mist onto the fire source to reduce the temperature of the fire source and inhibit the spread of flames.
Water-based fire extinguishers are suitable for various types of fires, especially those caused by flammable substances. They effectively cool the fire source and weaken the heat of the flame, thereby reducing the spread of fire. In addition, water-based fire extinguishers can flush smoke and harmful gases out of the fire scene, providing better escape conditions.
However, water-based fire extinguishers also have some limitations. First, they are not suitable for appliance fires because the c…
