Underlying causes of accidents in the process industry
The Major Accident Reporting System (MARS) created by the Commission of the European Communities in the framework of the implementation of the SEVESO-Directive in the JRC Ispra Site has collected data for about 100 accidents in the first six years of application of this Directive. Accident reports have been analysed so that both primary and underlying causes could be identified. The most dominant underlying causes are the managerial/organisational omissions accounting for about 90% of the accidents of which the causes are known, and design inadequacies accounting for about 70% of the accidents of which causes are known. This presentation discusses the classification of the causes of the accidents currently registered in MARS. Further lessons learned from these accidents relevant to human factors in a broader sense are also presented.
