Abstract
Monitoring of risk is a key element in the overall risk management process. Monitoring major accident risk is difficult because accidents are rare and monitoring therefore requires use of indirect measures rather than statistics. Extensive efforts are presently put into developing good indicators which can predict trends in major accident risk, as a basis for taking actions when risk is increasing. This paper presents a method for developing major accident risk indicators which uses a risk model as a basis. The risk model includes all key factors which influence the major accident risk, including human and organizational factors, and also describes influences between the factors. This gives a multi-level risk model, from which indicators can be identified. Through regular monitoring of these indicators, the major accident risk level can be followed closely. The method is described step by step and an example of application is also briefly presented.
