Progress in understanding processes underlying occupational accidents on the level based on case studies

The purpose of this work was to further the knowledge of contexts surrounding accidents on the level in occupational situations with a view to proposing suitable actions for the prevention of these accidents. The study, undertaken at three establishments belonging to a national rail transport company, was based on quantitative and qualitative analysis of accident-on-the-level data available at the establishments concerned, typology of these accidents, interviews with victims and activity analysis. Understanding accidents on the level through building scenarios makes it possible to consider the relevance of prevention actions, such as workplace or environmental design/remediation and machine access system design. Moreover, it also makes it possible to consider curtailing the injury-causing aspect of the physical environment by reducing its 'aggressiveness'. Finally, the prospects emerging from this work in the research field are discussed.
