Tunnel Safety

Tunnel Safety

FSD develops total fire protection solutions for new and existing road, rail and metro tunnels:

•    CFD simulations of fire and smoke development
•    design of evacuation
•    risk analyses
•    load-bearing and separation structures
•    spalling assessment for concrete exposed to tunnel fire scenarios

Nominal fire curves for buildings do not properly reflect real progress of a tunnel fire. In particular, the heating rate and ventilation conditions differ considerably when compared to more realistic tunnel fire scenarios or standard curves specifically developed for tunnels.
