SAFETY/FIRE | TECHNICAL


INTRODUCTION


Tunnel fires are a horror scenario, not only since the accidents in the Mont Blanc and Tauern tunnels in 1999, which claimed many lives. When it comes to detecting and locating the source


of a fire in a tunnel, every second counts. Special fibre optic cables, in combination with powerful measurement and evaluation technology, make it possible to reliably meet this requirement.
