Water is drained off to the image pickup position from a water draining nozzle and the evacuation is guided away from the position. The image pickup position of the image pickup means 10 is in the center of the flames, so the water is drained off to the center of the flames and the evacuation is guided away from the center of the flames. Consequently, sure initial extinction is performed and the evacuation is exactly guided.
