This paper describes extinguishing experiments to verify the possibility of increasing the efficiency of extinguishing low, medium and high pressure water mist charging by the electric field of high DC voltage. The experimental results confirmed the effects of the electrical voltage, the configuration of electrodes (anode, cathode), the volumetric water flow rate, water pressure and the type of mist nozzle. Higher extinguishing effect electrically charged water mist to extinguish showed a shorter times to extinguishment, a smaller volume of water to extinguish the fire and extinguishing a higher percentage of successful attempts. Benefit: faster and more efficient fire- fighting with less risk of injury and less consequential damages in a protected space.
