Abstract: An ergonomic study was carried out to evaluate the manual handling of loads and identify possible musculoskeletal conditions to establish preventive measures to reduce the risk in the worker in the balancing unloading area. To identify risk factors, information was collected through direct observation and photographs. To establish the ergonomic risk in the manual handling of loads, the OWAS (Ovako Working Analysis System) evaluation method was applied with respect to the postures to which it is exposed. By conducting the evaluation, sixteen postures were analyzed using the encodings of the back, arms, legs and load postures. Positions 9, 10 and 11 are the ones with the highest risk for the worker, obtaining a risk category 4, this means that it is necessary to adopt corrective actions as soon as possible. In addition, the Snook and Ciriello method was applied for the evaluation of load handling, for this method the ERGOSoft PRO software for Windows used in Ergonomics is used to facilitate the work of the prevention specialist with data collection from mobile technology. The results for the initial force gave a risk level between 1.5 - 2.0 with a value of 1.82 having a high risk due to being exposed to a significantly high force, for the sustained force the risk level is> 2.0 with a value of 3.33 having a very high risk due to being exposed to high force and overexertion, it is recommended that you include in your budget the performance of complementary examinations every six months for the control and prevention of musculoskeletal injuries due to activities that they involve efforts in the postures of the back, arms and legs.
