Diseño de programas de ergonomía para la prevención de lesiones musculoesqueléticas en la empresa SERVIMEX

Abstract

Abstract: This study addressed the significant prevalence of Musculoskeletal Disorders (MSDs) at SERVIMEX, a company specializing in the sale, recharging, and maintenance of fire extinguishers, where 80% of its technical-operational staff reports musculoskeletal pain. Since no previous ergonomic evaluations had been conducted and it was determined that the study sample was exposed to risk agents (physical effort, forced posture and repetitive movements), the project aimed to elaborate an ergonomic program to prevent this type of injury. For this purpose, a mixed-method analysis consisting of the REBA (Rapid Entire Body Assessment) method for the "Very High" risk positions and the Standardized Nordic Questionnaire for reporting of the prevalence of lower back and neck discomfort were employed. The findings confirmed elevated ergonomic risks and a high prevalence of MSDs; thus, the proposed ergonomics program includes specific workstation adjustments and complementary strategies to reduce the prevalence of musculoskeletal disorders, improve risk levels, and decrease absenteeism. Ultimately, this work provides a comprehensive solution to optimize working conditions, protect employee health, and enhance company productivity.
