Evaluación ergonómica de movimientos repetitivos en el levantamiento de cargas en bodegas de una industria manufacturera de sacos industriales.

Abstract

This case study analyzes the ergonomic risks arising from repetitive movements during lifting loads in the warehouse area of SACOPLAST S.A., a company dedicated to the manufacture of industrial sacks using polypropylene as its main chemical compound. The main objective was to assess these risks to propose corrective measures to improve working conditions and reduce the incidence of musculoskeletal disorders (MSDs). The company's methodology used a mixed approach (quantitative and qualitative), applying tools such as surveys of selected staff and medical data provided by the institution's medical department for the years 2023, 2024, and 2025, Annex 3 of Decree 255. The final data and conclusions show high exposure to repetitive tasks, awkward postures, and manual handling of loads, reflecting an increase in medical diagnoses such as low back pain, shoulder injuries, and wrist contusions. A 26% rate of absenteeism was identified as being linked to MSDs, affecting productivity, and generating economic costs for the company. The study contributes to the line of research on comprehensive health and chronic diseases and a simple methodological model applicable in similar industrial settings.
