Study of Three Seveso II Reports in Sweden: Are the Results Presented in the Reports Good Enough?
2007 (English)In: Proceedings of the 17th Nordic Research Conference on Safety.: June 13-15, 2007, Tampere, Finland., 2007Conference paper (Other academic)
presentation done in safety reports is to reveal risks using reliable methods and to gather informationfor rational decision making including physical planning and risk management.There are several difficulties connected to current use of risk assessment methods. One of thedifficulties is uncertainties in the probabilities estimation calculated in quantitative risk assessmentmethods. Other difficulties include unclear guidelines for the worst possible event and consequences ofan accident.Whenever a risk assessment is performed, there will be doubts about the objectivity of the results. Evenif mathematical models are building the basis for calculation, e.g. of risk frequency or scenarios used todescribe the possible consequences of an accident happening, elements of uncertainty could beidentified. These uncertainties could be used to manipulate the outcome of the assessment dependingon e.g. personal or political interests. In order to minimize the possibilities for influencing the results, astandard of how to perform a risk assessment has been established and it should be built on morequalitative and transparent principles.Another important demand on risk assessment and management today is that its results should becommunicated to different stakeholders. The communication aspect is stressed because of recognizedimportance of public participation during decision making processes.
