Ensuring the quality of safety analyses in industry

摘要

Although the use of safety analysis has increased and become common, the quality of the analysis, and the lack of resources are sometimes criticised. Some studies and experiences have made it obvious that the results depend on the analysis leader and the analysis team as well as the commitment of the analysis subscriber in industry. Quality systems developed for other industrial purposes offer means for developing methods and criteria to support the quality management of safety analyses. The quality management of safety analysis can be based on the evaluation of the analysis process and identification of its shortcomings, for example, by means of checklists. The high quality of an analysis can be best assured, while possible weak points are recognised and eliminated already when planning the analysis. In this, the role of the analysis leader is crucial. A research has been carried out for developing instructions and guidelines for leaders and secretaries of the safety analysis as well as for the subscribers to various safety analyses in industry. This paper discusses quality management, and means for improving the quality of safety analyses. The emphasis is on the roles of the analysis leader and subscriber, requirements for a good analysis leader, and means available for assuring the quality of safety analysis. The meaning and importance of the subscriber's role to safety analyses in industry are discussed.
