Evaluación ergonómica y propuestas de control mediante el método rula office en el área administrativa del GAD Municipal del cantón Tisaleo

Abstract

This project identified that the conditions of the workstations of the Administrative Area of the Municipal Decentralized Autonomous Government of Tisaleo canton, do not comply with the ergonomic guidelines for worker safety. Therefore, an ergonomic evaluation was proposed to determine the level of risk to which employees are exposed. The application of the Nordic Questionnaire for muscle-tendon disorders and the PVD inspection sheet showed the vulnerability to suffering from ergonomic muscle-skeletal disorders, such as low back pain, disc herniation, carpal tunnel syndrome, among others. The method used for the evaluation was RULA OFFICE, a specific method for the evaluation of office work, and the risk level was found to be between levels 5 and 6, and 7, that is, modifications to the workstations are required in the short term. Control measures are proposed based on the sizing of work furniture, specifically tables, and chairs, according to the anthropometric needs of the population of 27 workers of the organization, using the female 5 percentile and male 95 percentile, so that the furniture fits 90% of the population, and the establishment of a program of active breaks for physical and mental relaxation, through the development of muscular exercises. Through the implementation of the control measures, it is intended to reduce the level of ergonomic risk in the workstations; as well as to provide workers with the necessary information to prevent occupational diseases related to ergonomics.
