Introduction: The selection of suitable ergonomics risk assessments (ERA) is significant in producing significant results. The study’s main objective is to analyse the suitability of ERA methods for evaluating the risk level of above-shoulder reaching during the HS binning process through the application of marker-based motion capture. Materials and Methods: Methods selected for this study are RULA, REBA, NERPA, MAC, QEC and RNLE. Three participants were chosen to wear a Mocap suit with 25 markers placed on joints and rigs. The participants performed above-shoulder reaching with a load of 2.1 kg at 2.05 m height. RULA is acting as a basis for comparison for this study. Result: RULA rated the posture majority (66.67%) as “high risk”. Conclusion: Based on the Mann-Whitney U Test, RULA, REBA, and NERPA proved that they are suitable for evaluating above-shoulder reaching during the HS binning process.
