PROBLEM TO BE SOLVED: To concurrently monitor operating time of appliances during detection of CO gas. SOLUTION: The gas cutoff system comprises: a flow rate registration means 28 for registering an average flow rate obtained after detection of flow rates by classifying and storing the flow rates by a flow rate storage means 26 and registering the average flow rate as an appliance flow rate; a CO gas leak determination means 29 for inputting output signals based on the concentration level of CO gas leak from a CO alarm 20; an appliance estimation means 30 for storing the output signals of the CO gas leak determination means 29, a group of flow rate patterns stored by the flow rate storage means 26 when flow rates are registered by the flow rate registration means 28, and the registered flow rates, and estimating the appliance with the gas leak; a CO abnormality determination means 36 for monitoring during the operating time by output from the appliance estimation means 30; and a communication means 35 for notifying appliance information.
