Manual handling is recognized as one of the occupational activities with a high risk of musculoskeletal disorders (MSDs). This descriptive study aims to analyze the risk factors of manual handling tasks, specifically lifting and lowering loads by Stevedores.The research was conducted at a site owned by a logistic and port service company, involving 10 Stevedores as a sample. Musculoskeletal complaints were assessed using the Nordic Musculoskeletal Questionnaire (NMQ), while risk levels associated with lifting activities were evaluated using the NIOSH Lifting Equation. The findings indicate that 6 out of 10 workers reported complaints related to musculoskeletal disorders. Additionally, 9 out of 10 workers were found to be at a moderate risk level during lifting activities, and 6 out of 10 were at a moderate risk level during lowering tasks. Environmental measurements revealed that the thermal work environment met regulatory standards, whereas lighting levels did not comply with the required thresholds.
