Technical note on the contribution of sociotechnical factors to accidents notified to MARS
To reveal in a structured way how organizations manage safety at their plants, classification schemes can be applied to identify plant-specific precautions on different hierarchical levels (eg from top level equipment reliability to bottom level safety climate). In this paper, such a model is used to classify the accidents reported to the European Commission's major accident reporting system (MARS) according to the levels on which failures resulting in actual accidents did occur, and to cross-compare the levels of causation with the overall severity of the accidents. It is analytically shown that approximately 66% of the accidents are caused by latent safety management systems (SMS) failures, and that those accidents which are caused by failures in the deepest layers of latency are of significantly higher severity than accidents caused by more immediate failures.
