Tunnel Safety


Safety in underground transportation facilities is affected by many factors.

Among these, the conservation of smoke-free escape routes is of paramount importance in case of a fire incident.

The tunnel itself, cross passages, escape tunnels or emergency stair cases form complex confined air spaces. Counteracting forces like wind pressure or heat-generated buoyancy have the potential to turn around the anticipated movements of fresh air and to allow smoke entering and blocking escape routes.

Contribution to the development of a comprehensive tunnel safety concept.

Assessment of possible ventilation and smoke extraction scenarios for a given design and application of appropriate methods to evaluate the safety in these scenarios.

Assistance in finding the optimum tunnel ventilation design in consideration of safety issues, economic feasibility and regulatory or contractual requirements.
