P-384 ASSESSMENT OF MUSCULOSKELETAL DISORDERS (MSDS) AT THE MANUAL MOLDING STATION WITHIN A MICROELECTRONICS COMPANY

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.
