Smoke extraction systems can be significantly reduced
Particularly in so-called island transport systems, such as urban transport operations with dedicated fleets, considerable added value can be generated by incorporating fire protection solutions into a holistic approach. For example, if a vehicle is already equipped with a fire protection system that ensures control over a fire scenario in that vehicle, why should the associated underground passenger transport system still be designed for a full-scale fire? With the holistic approach, the Smart Concepts by FOGTEC solution, it is possible to optimize investment costs in urban infrastructure projects, demonstrably by well over 50%, while simultaneously improving the situation for evacuation and emergency concepts.
The best-known reference at present is the implementation in the Los Angeles Metro, where the equipment of the vehicles and the resulting influence on the fire scenario, the requirements for the stations and the infrastructure for the route extensions have just as positive an effect as in the context of increasing the frequency on the existing routes.
FAQ – Fire Protection in Smart Concepts Underground
How can the justification for smaller smoke extraction systems be achieved?
With an active fire suppression system, the maximum fire load of the vehicle is significantly lower.
As a result, the worst case scenario used for designing the smoke extraction system is reduced, allowing for smaller and more efficient installations.Are architecture and fire protection conflicting requirements?
No, with an active fire protection system, architectural flexibility can actually be increased, enabling a wider range of design options.
