Abstract: In order to study accumulation effects of errors during accident incubation and development process, a research idea of cumulative effects is introduced. Firstly, cumulative characteristics of errors were analyzed with methods of theory analysis and case study to explore relationship between cumulative effects of errors and occurrence of accidents. Then based on these effects, accident process was divided into six stages, and an accident causation model on the basis of fault accumulation effects was constructed to clarify their cumulative characteristics at each stage. Finally, this model was applied to a case study to verify its effectiveness and feasibility in analysis of specific accidents. The research shows that accidents are caused by cumulative errors and triggered by triggering events in socio-technical systems of enterprises and safety culture development proves to be a fundamental measure for accident prevention.

Key words: human error, cumulative effect, accident process, accident causation model, case analysis
