Compréhension des perturbations accidentelles du mouvement dans l’activité dans une perspective de prévention

Abstract

performance and the failure of movement control in the activity. Movement, inseparable from the activity of which it is a part, emerges from interactions in the occupational situation, just like activity. Its control simultaneously and inseparably targets the performance of the task and the avoidance of accidental movement disturbances. First of all the risk of AMD is characterized; the control of movement in the activity is then presented. The diversity of risk situations and its effect on prevention are then discussed, as are the variabilities in work situations, variabilities to which the regulations respond and from which the AMDs emerge. Time management in relation to the AMD risk is then illustrated using accident analyses. Finally, a framework focusing on the activity is proposed for analyzing movement in the activity in both usual and accidental situations.
