CONSTITUTION:A light receiving device 3 receiving a laser beam HL is fitted to an outer upward face of a helmet 2, and alarm lamps 4a-4c are fitted to a height of a forward forehead of the helmet 2 and a head top and a rear head at the outside of the helmet 2 respectively, they are connected to the light receiving device 3, and the alarm lamps 4a 4c are lighted by the reception of the laser beam HL by the light receiving device 3. When a worker (h) wearing a helmet enters a warning zone set by the laser beam HL, the alarm lamps 4a-4c are lighted in linking with the reception of the laser beam HL by the light receiving device 3.
