In 1999,Law Concerning Special Measures against Dioxins was enacted. An incineration plant exceeding the effluent standard of dioxins stops operation and the plan of demolition is carried out. When demolish an incineration plant polluted by dioxins,it is necessary to ensure workers safety, neighbors health and their living environment. Authors have developed an automatic equipment which removes ash containing dioxins inside of the chimney pipe of an incineration plant with high-pressured water. This equipment could be operated by remote control and set workers free from heavy work at high and narrow space in a chimney pipe. Moreover, exact removal of ash is possible by automatic control. An opening and closing type of tent for environmental safety and an information system which provides scenes of site works, revel of noise and vibration, particle counts and process of discharging toxic wastes to neighbors are also made up. This paper reports an automation of a chimney demolition and a case of risk communication with information disclosure.
