Gestión preventiva de riesgos ergonómicos aplicando el método ROSA en las agencias de recaudación de la Empresa Eléctrica Riobamba S.A. provincia de Chimborazo

Abstract

The collection staff of Empresa Eléctrica Riobamba S.A. is in a situation where they are confronted with several ergonomic risks, which are the cause of musculoskeletal symptoms. The objective of this technical project was the development of a preventive management of ergonomic risks to reduce and/or eliminate the different ergonomic risks in the workplace, in order to avoid the various musculoskeletal disorders. For which, initially the presence of musculoskeletal symptoms was identified through the application of Kuorinka Nordic questionnaire, with the results the agencies whose workstations require a thorough analysis were determined, then the activities implemented during the workday were evaluated by application of ROSA methodology (Rapid Office Strain Assessment) to know the risk and level of action required by each of the workstations under study to develop preventive and corrective measures based on the outcomes of this methodology. On the other hand, through the application of Nordic Kuorinka questionnaire, it was concluded that 55% of the collection staff had discomfort, with the greatest amount concentrated in the lower back and neck; on the other side, through the application of ROSA methodology, it was confirmed that 75% of the collection staff had a very high risk, 5% extreme risk and 20% high risk. Therefore, preventive and corrective measures were proposed to mitigate the current ergonomic risks in each evaluated work position, some of these are: to carry out a training program on ergonomic risks in front of data display screens (DSP), to implement a program of active breaks and to acquire ergonomic work elements and furniture.
