Abstract: |
In absolute terms safety describes a state which is free of any hazard. Indeed, such a state is not achievable - independent of the available technology and the financial resources. To achieve a safe system can only be a conditional objective. Thus the question arises "How safe is safe enough?" The question has been systematically treated for years using quantitative risk analysis and evaluation. Nowadays risk acceptance criteria are often clearly defined. However there is still a large area of discretion, where costs and benefits of additional safety must carefully be weighed. Such balancing is particularly difficult, if the technology to improve safety is available but it is expensive and their effect on safety is potentially small. The presented paper addresses a practicable methodology to evaluate the appropriateness of additional safety measures using cost-effectiveness-criteria. It has been applied in numerous projects related to safety in tunnels. |
