Abstract Objective assess the musculoskeletal constraints resulting from carrying out the task at the cutting station. Method three methods were used: - the OSHA (Occupational Safety and Health Administration) checklist to detect work situations at risk of MSD of the upper limb. The normal score must be 5. - RULA (Rapid Upper Limb Assessment) requires analytical observation over several work cycles to select the most frequent and/or most restrictive posture a priori. It takes into account the entire body posture. The acceptable score should be between 1 and 2. - OREGE (Gesture Identification and Evaluation Tool) aims to evaluate the biomechanical risk factors for MSD of the upper limb. This analytical method makes it possible to evaluate the three risk factors: effort, extreme joint positions and repetitiveness. Results The activity consisted of eight phases: verification of batch conformity, input self-check, loading of the machine, start-up of the machine, output self-check, placing the treated batch in a bin, entry into factory works and movement of the filled bin. The score obtained by the OSHA method was 4. The workstation seems suitable since it is 5. The most restrictive risk factor was the poor posture adopted when retrieving the cases from the machine exit side. The RULA score was equal to 4; job changes were necessary. The OREGE scores indicate that the actions were not recommended or to be avoided and the position must be quickly adapted. Discussion and conclusion The company must develop a participatory preventive strategy involving all social partners.
