Implementación de medidas de prevención y control de riesgo ergonómico por levantamiento de pesos y posturas forzadas en el área de despacho del Comercial Vera de la ciudad de Riobamba

Abstract

Commercial Vera workers were often subjected to physical stress or forced postures, for this reason, it was important to carry out an assessment and identification of the risk factors, which formed a basis for an appropriate adaptation of the workplace to each activity carried out. The aim of this study was to implement measures to prevent and control ergonomic risks from heavy lifting and awkward postures. The current situation of the workers was analyzed using the Nordic questionnaire, which made it possible to identify the areas of the body with the greatest musculoskeletal disorders. The Rapid Entire Body Assessment (REBA) method was then applied to the forced postures and The National Institute for Occupational Safety and Health (NIOSH) method was used to analyze weight lifting by workers in the shipping area. The results showed that the areas of the body with the greatest MSDs were the lower back at 20% and the neck at 16%. Finally, analyses of the forced postures showed that 17% of the workers presented a very high risk while 33% presented an intolerable risk when lifting loads. It is concluded that the application of the REBA and NIOSH methods has made it possible to identify and assess the risk factors in the shipping area in order to implement the correct preventive measures proposed based on the results of the assessments carried out.
