Evaluación ergonómica del área levantamiento y descenso manual de carga de la Empresa Gamboa Pellets ubicada en Baños de Agua Santa.

The study named "Evaluación ergonómica del área levantamiento y descenso manual de carga de la empresa Gamboa Pellets ubicada en Baños de Agua Santa" is aimed to identify, analyze, and evaluate the ergonomic risk associated with these tasks, in order to prevent workers's musculoskeletal disorders (MSDs). The research was justified by the high prevalence of MSDs and their significant impact on industrial sectors, occupational health, and economic costs derived from occupational injuries and diseases. A quantitative approach with a non-experimental, cross-sectional, and correlational design was used. The sample included 5 workers from the raw material landing points (3) and the final product storage stations (2). Validated tools were applied: the Kuorinka Nordic Questionnaire to detect MSD symptoms, the MAC Method to evaluate ergonomic risks, and a checklist based on ISO standards. The situational diagnosis showed a 54.63% infringement of ergonomic standards, especially in load limit characteristics and physical effort. Furthermore, 100% of workers reported pain in their shoulders, lower back, and hips/legs, associated with postural factors and handling heavy loads (22-23 kg). The MAC method classified the risk as moderate to high (scores from 11 to 15), highlighting factors such as weight, frequency of lifting, and inadequate distances. Thus, it was concluded that corrective measures are urgently needed to reduce ergonomic risk and improve working conditions. The research provides quantitative evidence for preventive management in SSO.
