A test bench for an aircraft turbojet engine is provided. The test bench comprises a U-shaped configuration with a passage in the form of an elongated corridor, an inlet duct, and an outlet duct. The corridor comprises a fixing zone with a fixing arm for holding a turbojet engine during testing. The passage furthermore has an upstream shutter with vertical pivoting air guides and a downstream shutter with an inflatable balloon in a collector tube. In the event of fire, the shutters close to confine the turbojet engine in order to suffocate the fire rapidly. A method for managing a fire in a test bench with a passage is also provided. Shutters are placed in the passage, where they deploy.
