Luxembourg street tunnel with an exemplary fire protection concept
Accidents in tunnels with fire consequences make for shattering headlines time and again. What can be done about such catastrophes? Luxembourg, although small in area and mainly known as a financial location and as the home of the headquarters of a number of renowned European Institutions, is undertaking a targeted attempt to make its road network the safest in Europe.
One example of these endeavours is the Markusbierg Tunnel, opened in the late summer of 2003 and part of the motorway which links Luxembourg and Saarbrücken. A sophisticated security concept has enabled the establishment of a system of hazard notification, alarms and fire-fighting which is unprecedented in Europe. The security technology deployed has been supplied by Securiton GmbH, part of the Swiss Securitas Group.
Gaining time through ongoing temperature measurement
For this reason, the main security planning focus for the Markusbierg Tunnel was on rapid and precise fire detection and on the efficient provision of information to road users via a high-performance sound system supported by radio announcements. The linear SecuriSens TSC 511 heat detector, developed by Securiton, was installed in Luxembourg for the first time. This system provides rapid, reliable detection, a high degree of protection against downtime and wide-ranging software evaluation. This enables it to fulfil the demanding conditions for heat detection class A1-D pursuant to the EN 54 Standard.
