For the design and operation of major infrastructure projects, quantitative and qualitative risk analysis becomes increasingly important. Risk analysis is used to optimise the safety concept with respect to costs and benefits. Furthermore, quantitative risk analysis is formally employed in order to evaluate the risk category for the transport of dangerous goods in road and railway tunnels or on alternative routes. Several different methodologies are used today. The selection of the appropriate method is made according to project related or national requirements.

Fires in underground transport system have to be considered at an early design phase of a project. Based on a comprehensive risk assessment and a useful combination of preventive and curative measures, it is important to find the optimum solution for a given project. Evacuation and rescue concepts are important requirements for a successful handling of underground fires.
