Experts of the Swiss Federal Office for Roads regularly test the fire control systems of Swiss tunnels.
During the night of 30th April, 2015, these experts tested in the Milchbucktunnel in Zurich whether all fire control systems were functioning without fault. As you can read in the newspaper report of the Tagesanzeiger, all fire detection devices functioned to the experts’ satisfaction.
In the Milchbucktunnel, the following SIGRIST measuring instruments have been installed:
- VisGuard In-situ for visibility measurement
- FireGuard as smoke detectors
All measuring instruments operated perfectly in this test. In case of a real fire, people and material are actively protected by the reliability of our SIGRIST instruments.
