Drop the pressure

For a fire to survive, it must rely on the presence of the three elements of the 'fire triangle': oxygen, heat and combustible material. The removal of any one of these elements is enough to suppress or extinguish a fire. While traditional water sprinkler systems remove only the heat element of the triangle, water mist systems remove both the heat and oxygen elements by dispersing water through specially-designed nozzles. The smaller a water droplet's size, the larger its surface area becomes and thus the more effective the system is in rapidly reducing the temperature of a fire. To put it another way, when water is converted to steam - which is what happens to the water droplets in water mist - then a large amount of energy is taken from the fire, which results in rapid cooling.
