Italian legislation on the subject of Workers’ Health and Safety recalls the ISO standards for the ergonomics analysis and mentions the OCRA method as ‘preferred’ for risk assessment of upper limbs overload. Over the years, other methods for ergonomics risk assessment not currently mentioned in ISO Standards, were developed. As for example, EAWS method – proposed by International MTM network for ergonomic design and analysis of workstations – is greatly adopted by automotive OEMs because of its integration in the ErgoUAS system that allows to define the sequence of tasks and the time needed to perform related to the biomechanical load. This paper presents the “Cut Off” Project developed to define a risk assessment procedure for upper limbs based on the combined use of EAWS section 4th and OCRA Checklist. “Cut off” are a set of criteria, related to the main risk factors for upper limbs musculoskeletal disorders, characterized by threshold values based on EAWS section 4th. The aim of the procedure is to apply EAWS section 4th to all manual workstations during both design and risk assessment phase and to analyze with OCRA checklist only workstations, characterized by the overcome of one or more thresholds based on EAWS factors. The procedure is going to be constantly monitored and possibly improved by new data collection. |
