Ergonomisk förbättring vid hanteringen av L1-prover på provhanteringen : Förstudie på SSAB EMEA AB i Luleå
The staff at the sampling handling at SSAB EMEA AB in Luleå is currently experiencing some Musculoskeletal disorders (MSD) due to manual handling of the L1 samples. Some MSDs has been experienced for some years and to reduce the risk of MSDs there is a need for change in work operations. The project...
