Structural Fire Protection in Tunnelling

Electrical function maintenance

The fast and safe evacuation of people in the event of fire requires that all relevant safety equipment is not impaired in its function. For the most part, road tunnels are therefore equipped with electrical wiring systems (cables + distribution boards) that are used, in addition to the general supply of power, for the power supply of safety-related systems inside the tunnel that must maintain its function for a certain period of time (maintenance of performance 90 min) in the event of a fire (e.g. night-time illumination / emergency lighting / fire emergency lighting, smoke extraction, extinguishing devices, etc.). The greatest potential fire hazard comes from vehicles on the roadway. But the general power supply may also adversely impact safety-related systems or even stop them from functioning in case of its malfunction with a consequential fire.

The consistent use of standardized fire protection products with national technical approval eliminates these risks to a large extent and thus guarantees a higher level of security in the overall security concept of road tunnels.

Tested quality & safety in tunnel construction

As the market leader in constructional fire protection in traffic tunnel systems, the subject of safety is of central importance to us. To guarantee a maximum of safety, our products as well as their manufacturing processes are subject to a continuous, independent quality control.
The current, summarized expertise by Materialprüfanstalt Dresden [material test body Dresden] certifies that our products fully fulfill the requirements of RABT, ZTV-ING part 5 para. 4 and TL/TP TTT.
This means that our products can be used without reservations for tunnel projects.

The products for the tunnel area where evaluated with respect to the following basics:

  • EG Tunnel directive 2004/54/EG
  • RABT 2006 – Guidelines for the equipment and the operation of street tunnels
  • ZTV-Ing part 5 para. 4 – Technical operating equipment of street tunnels
  • TL/TP TTT – Technical terms of delivery and technical test regulations for doors and gates in street tunnels
  • DIN EN 60529 Protection types IP
