Evaluación de riesgos biomecánicos mediante los métodos REBA y RULA en el personal operativo del Supermercado 'BaYes' de la ciudad de Zamora.

Abstract

Abstract: The present research aimed to evaluate the level of ergonomic risk in the workstations of Supermercado BaYes through the application of the REBA (Rapid Entire Body Assessment) and RULA (Rapid Upper Limb Assessment) methods, in order to determine the need for preventive intervention. Gathering data for the study was performed via a quantitative research method with a descriptive scope that was used in a non-experimental observational setting. The population used for the study was made of nine employees working on both operational and administrative fronts. Out of the nine employees, eight were assessed using the REBA methodology, while the administrative employee was assessed using the RULA method based on biomechanical characteristics involved in the relevant activities. The various methods and tools used to collect and analyze data to evaluate postural behavior were direct observation, video recording, Ergo checklist, and ErgoIA. The findings from REBA indicated that the risk levels presented by the employees were 62.50% low risk, 25.00% medium risk, and 12.50% high risk with packers ranking first priority for intervention. The employee evaluated using RULA received scores of between three to four points which falls to action level two. The primary biomechanical demands faced in the activities of the employees are related to the neck, trunk, and upper limbs, although many factors may be altered. Based on these findings, recommendations and an ergonomic intervention plan were established to control the identified risk factors and improve the working conditions of Supermercado BaYes employees.
