Abstract: PURPOSE:To quickly extinguish smoke in the case the room is filled with smoke by providing a spray nozzle provided on an indoor ceiling part or a wall part, a high pressure water supply part for supplying high pressure water to which a surface active agent is added within a range of specific PPM to this nozzle, and a control means for controlling the supply of the high pressure water to the spray nozzle. CONSTITUTION:When a building passage 100 is filled with smoke, a smoke sensor 3 (control means) outputs a signal corresponding to smoke density to a discriminating part 4 (control means), and when the smoke density exceeds a prescribed level, the discriminating part 4 opens a valve device (control means), and sprays water droplets of fine particles through a spray nozzle 1 from a high pressure water supply part 2. The water droplets catch smoke particles on the way of dropping down, and extinguish smoke in the passage 100. To the water droplets, positive high potential is given, therefore, smoke particles generally electrified to negative are caught by electrostatic force. Also, since a surface active agent of 1-3000PPM is added to the water droplets, the water droplets come to easily smoke particles, and the smoke particle catching capacity of water droplets is improved remarkably.
