Servicing and Maintenance of Water-Mist Fire-Fighting Systems in Road Tunnels

摘要

Operators are deciding ever more frequently to equip their tunnels with a water-mist fire-fighting system (water-mist FFS). Here, water-mist FFS should not be regarded as "add-ons", but should, instead, be integrated into the overall safety concept from the very start of the project. Regular servicing and maintenance is necessary to assure the availability of the FFS. This, of course, also applies to many facilities in the tunnel, such as the lighting, ventilation and event detection systems, for example. Recently, and particularly in Germany, the question has arisen of what costs will be incurred from installing fire-fighting systems.
