PROBLEM TO BE SOLVED: To reduce a workload after operation confirmation testing in powder fire extinguishing equipment that ejects powder fire-extinguishing agent stored in a tank.SOLUTION: Powder fire extinguishing equipment includes: a tank in which a powder fire-extinguishing agent is stored; an actuating cylinder in which actuating gas is encapsulated, and which is connected to the tank through an actuating gas supply line; a pressure actuated main cylinder in which powder fire-extinguishing agent injection gas is encapsulated, and which is connected to the tank through a powder fire-extinguishing agent injection gas supply line; and a pressure introducing line for connecting the tank and the pressure actuated main cylinder. The powder fire extinguishing equipment also includes a tank bypass line for connecting the actuating gas supply line and the pressure introducing line, a tank bypass line opening/closing valve provided in the middle portion of the tank bypass line, and an actuating gas supply line opening/closing valve provided in the middle portion of the actuating gas supply line closer to the tank side than the tank bypass line connection part.SELECTED DRAWING: Figure 1 |
