Abstract
PURPOSE: To display the escape direction to workers in a concrete manner with increasing the reliability of alarm circuit by equipping with either display device or sound alarm device which informs the workers in plural regions of the safe escape direction.
CONSTITUTION: A nuclear reactor facility 12 is partitioned into four rooms, or regions A to D, by means of walls and doors 14, and detectors 101 to 104 and display device 20 are installed in each region. Each one of the detectors 101 to 104 is connected to a power source 6 and relay circuit 21, and a blue light 22 is lighting while the detectors do not detect radiation. When one of the detectors 101 to 104 detects radiation, the relay circuit 21 illuminates one or both of alarm lamps 24, 25 through a control circuit 23. Operating a sound generator at the same time, the relay circuit 21 is connected or disconnected by the control circuit 23 even if a leak accident takes in any region so that the reliability of the system may be enhanced. Thus, a proper escape method may be indicated to each worker.
