Packer’s workload assessment, using the OWAS method
Journal Title: Logistics and Transport - Year 2013, Vol 18, Issue 2
Abstract
One of the elements of the logistics system is the subsystem of production, which is a combination of physical elements such as machinery and equipment, tools, and (most importantly) people. Furthermore, systems dependent on the human-operator are particularly susceptible to problems from discomfort, leading to reduced production quality and an increase in the cost of training and absence from work. The aim of this study was to assess the workload and risk of musculoskeletal discomfort (MSDs) in the position of a logistics-packer, through an analysis of risk factors. A computerized version of the OWAS (Ovako Working Posture Analysis System) method was used to conduct the evaluation, in which 10 steps of the product packaging process were assessed. As a result of the assessment for the category of action categories (AC), six steps qualified as AC 1, 2 steps as AC 2, and 2 steps as AC 3. The main factors affecting the risk of a negative assessment of posture were keeping the back bent and twisted and keeping the legs bent at the knees. Work on the assessed position for two activities is associated with a significant risk of MSDs, therefore corrective actions should be carried out as soon as possible. Ergonomic intervention should be linked to: revision of the position and methods of work. After making changes to the assessed position, re-evaluation with the OWAS method is recommended to verify the effectiveness of the changes.
