METHOD FOR WARNING LEAKAGE OF HAZARDOUS CHEMICALS

摘要

The present invention relates to a hazardous chemical leakage alarm method, and relates to a hazardous chemical leakage alarm method that promptly informs residents within an influence range of the leaked chemical to evacuate. A method for warning of hazardous chemicals leakage according to a third aspect of the present invention is a method for detecting and alarming hazardous chemicals leaking from a plurality of storage tanks disposed in a discharge wall but in an area defined by a flow path, A first step of detecting a leakage of the chemical by a leak detection means installed in the discharge wall when a chemical substance leaks from at least one of the plurality of storage tanks; The change value of the level gauge installed in each of the plurality of storage tanks is measured, the change value of the flow gauge installed in each pipe connecting the plurality of storage tanks and each process facility is measured, and then the change value of the level gauge A second step of recognizing how many chemical substances have leaked from which storage tank among the plurality of storage tanks by comparing the change value of the flow rate gauge and; A third step in which the type and amount of leaked chemical substances recognized in the second step are transmitted to a control unit through wireless communication; And a fourth step of sending, by the control unit, a disaster message to local residents within the affected range by using a database obtained by calculating the influence range of the chemical substance stored in the storage tank according to the Chemical Substance Management Act.
