Abstract Introduction The objective was to assess the risk of MSDs by using 3 simple and rapid methods. Methods OSHA (Occupational Safety and Health Administration) screens for situations likely to be at risk of MSDs of the upper limbs. The normal score is 5. RULA (Rapid Upper Limb Assessment) requires observation over several work cycles to select the most frequent and/or most restrictive posture a priori. The acceptable score is between 1 and 2. OREGE (Gesture Identification and Evaluation Tool) is an analytical method for evaluating the three risk factors: effort, extreme joint positions and repetitiveness. Results Shift work (3x8) with a half-hour break is carried out while standing. The complete work cycle of an operation lasts 3 minutes and 20 seconds. Each cycle includes eight different tasks: supplying the molding station with boxes containing frames and a stock of resin; taking frames of the boxes and placing them on the grill; preheating the resin; placing the pre-filled grill on the mold; deposition of the resin above the mold; recovery of the grill and unloading of the molded frames; storage in lockers transferred periodically to a table located 5 meters away; cleaning the device with a blower and brush. OSHA score = 4; the position is suitable. RULA made it possible to study the mold cleaning phase; its total score = 6 requires immediate modifications. The OREGE scores indicate that the actions were not recommended and the position must be quickly adapted. Discussion and conclusion The company must develop a participatory preventive strategy involving all social partners.
