Abstract

Material handling activities in workshop units can potentially create musculoskeletal disorder complaints and injuries to workers. To reduce this potential for injury, it is necessary to analyze and improve the work system design. This study uses a participatory ergonomics approach to analyze the work system design in a workshop unit at company "X". Participatory ergonomics emphasizes the involvement of workers and ergonomics experts in discussing the improvements needed for work system design within a Focus Group Discussion. An ergonomics evaluation was carried out as a means of observation and analysis using the Nordic Musculoskeletal Questionnaire, a Quick Exposure Check, and the NIOSH Lifting Equation. Focus Group Discussions were conducted by the ergonomics team and led to the following improvements: (1) socialization of correct manual handling, (2) installation of work safety posters, (3) selection of hearing protection equipment, (4) selection of hand protection equipment, (5) stretching and reduction of workloads and repetition in material lifting, (6) changes in workplace layout, and (7) design of step ladder aids. The improvements to the work system design were evaluated by dividing workers into a control and an experimental group. Data analysis results showed a decrease in the level of musculoskeletal complaints by 55.9%, a decrease in the average index of risk exposure level by 25.2%, and no potential risk of injury to the lifting activity.
