Evaluación ergonómica y propuesta de medidas de prevención mediante el método REBA en los conductores de la Cooperativa Estrella de Octubre localizada en Guayaquil

Abstract

In this technical project, an ergonomic evaluation was carried out and preventive measures were proposed using the Reba method for the drivers of the Estrella de Octubre Urban Passenger Transport Cooperative, through the application of the aforementioned method to improve the quality of work in terms of incorrect postures and to identify negative factors. Due to the work activity that a driver carries out, they can suffer from stress, musculoskeletal problems resulting from incorrect postures due to the long working day, and the repetitive routines that the drivers carry out daily. The development began with the analysis of the current situation of the drivers, whose information was collected employing a survey and a Nordic questionnaire for musculoskeletal disorders, subsequently, the REBA method was applied where the different positions that the body adapts in a posture were evaluated, the result of which gave a medium risk level (4-7), and a necessary level of action, which led to the intervention for the application of improvements in the ergonomic area for the different drivers. Finally, preventive management was based on the technical dimensioning of the driver's seat according to the anthropometric measurements collected, which must comply with ergonomic lumbar support, a plan for active breaks to help improve posture, and recommendations on the basic ergonomic rules on the correct posture when sitting in the seat, gripping the steering wheel and gear lever. Therefore, it is recommended that an Occupational Health and Safety Committee be set up to periodically assess the health of the cooperative's drivers.
