Packing products for customers

摘要: The introduction of laser scanners at supermarket checkout areas has resulted in previous ergonomics studies focusing specifically on the scanning process and associated cumulative trauma disorders hands arms. Few have evaluated increased musculoskeletal load exertion staff when they are also expected to pack products into bags for customers. This paper describes an evaluation three different designs workstation, which require operator stand scan products, them plastic transfer packed customer. Musculoskeletal with checkouts were measured using OWAS, heart rate recordings ratings perceived exertion. In addition, subjective rankings workstations obtained productivity each design examined as part evaluation. Some variables showed significant differences postural between workstations. results formed basis recommendations improved workstation design. suggestions made reduce increase include positioning weigh scale side bag frame beneath scanner.
