Propuesta de rediseño ergonómico del puesto de trabajo de estibador de producto terminado en la línea de producción de aditivos.

Abstract

This final master's project aims to practically apply the knowledge acquired during the Master's Program in Occupational Safety and Health, with an emphasis on the physical ergonomics associated with manual lifting and awkward postures. The study focuses on the ergonomic analysis of the finished product stacker's position on the additives production line at Aditivos y Alimentos S.A. Adilisa, an organization located in Guayaquil, Ecuador. The goal is to identify ergonomic risk factors, assess the level of worker exposure, and propose redesign alternatives to control these risks, thereby improving working conditions and preventing potential occupational diseases such as musculoskeletal disorders. To this end, internationally recognized methodologies were applied, such as ISO/TR 12295:2014 for the identification and estimation of ergonomic risk, and ISO 11228-1:2021 for the specific evaluation of manual lifting. The results revealed significant exposure to risk factors such as loads exceeding regulatory limits, high handling frequency, inadequate lifting heights, and unfavorable postural conditions. Based on these findings, ergonomic intervention proposals were formulated, encompassing structural, organizational, and training aspects, including prospective simulations. These proposals are grounded in the Ecuadorian legal framework and international standards. This project constitutes an unimplemented technical proposal, developed within the academic context of a Master's program in Occupational Safety and Health, endorsed by the Catholic University of Santiago de Guayaquil.
