Accident Scenarios Triggered by a Movement Disturbance in the Construction and Metallurgical Sectors : For a Local and Diversified Prevention
The prevention of injuries caused by collisions, slips, or any other movement disturbance at work represents a major challenge. 143 written accounts of accidents in the construction and metallurgy sectors were analyzed using a Bayesian approach to extract recurrent scenarios. These accounts were characterized by 30 generic factors followed by 8 recurrent scenarios. Movement disturbances most often occurred when the worker was manipulating an object. They can be explained, in particular, by the occurrence of technical incidents and the presence of coactivities or constraints related to collective work, which emphasizes the role of work organization. Depending on the occupational sector considered, the identified factors/scenarios were sometimes more present in one sector than the other, sometimes less so, and sometimes absent altogether. Our results confirm the need for local, diversified prevention that combines production and safety rationales and that strives for a balance between a defensive conception of safety and increased system resilience.
