A new approach to ergonomic physical risk evaluation in multi-purpose workplaces

Abstract

The profile of human factors and ergonomics is rising. To provide an ergonomic work environment, it is necessary to pay special attention to the design and evaluation of the workplace. Traditional production work practices do not sufficiently take into account task variability in job design and assessment. Variations in task content, organizational work performance are seen due to the effective use of equipment, which enables higher levels of productivity to be reached. However, this variation has an impact on physical ergonomics risk factors and, consequently, on the risk of developing work-related musculoskeletal disorders. Variations can cause difficulties in assessing workers' exposure to ergonomic risk. This study aims to develop a framework for the evaluation of physical ergonomic risk in multi-purpose workplaces. The presented framework integrates the concepts of well-known observation techniques used in the assessment of physical ergonomic risk factors in the multi-purpose workplace. The research framework highlights a worker's exposure to the ergonomic risk and illustrates how these results can be used to find solutions in future ergonomic interventions. The framework's application is presented by illustrative case studies. Theoretical, managerial and practical features of the framework are discussed.
