description PROBLEM TO BE SOLVED: To provide a gas shut-off device that can regulate a rate of gas flow according to a concentration of oxygen in an environment, where gas appliances are used in a residential space.SOLUTION: The gas shut-off device 4 includes: an oxygen concentration sensor 11 for detecting a concentration of oxygen in the residential space S; a flow rate measurement unit 10 for measuring a rate of gas flow; a flow rate regulating unit 12 for regulating a rate of gas flow; and a controlling unit 13 for controlling an operation of the flow rate regulating unit 12. The controlling unit 13 drives the flow rate regulating unit 12 according to the concentration of oxygen in the residential space S detected by the oxygen concentration sensor 11, to regulate a rate of gas flow to a gas appliance 6.
