Estudio comparativo entre el método check list OCRA y RULA-RULER para la evaluación de riesgos ergonómicos asociados con sufrir enfermedades musculoesqueléticas en operativos de línea

Abstract

Currently, labor ergonomics is a highly studied topic given the importance it has for organizations, as a branch of Occupational Safety, is responsible for providing an adequate place for the worker in favor of preventing occupational diseases such as musculoskeletal injuries, which are generated by ergonomic risk factors such as forced postures, repetitive movements, handling of loads, among others, this information is vital for organizations not only for mitigation and / or elimination if not as part of compliance with legal regulations for safety and health for workers valid in the country. In the present work of investigation, the comparison between the methods of ergonomic evaluation RULA-RULER and Check List OCRA was made, focused to the analysis of the postural load and the execution of repetitive movements correspondingly, in the Operational Line work station in a company of the city, where ergonomic shortcomings were observed when performing the activities of the workplace, this through a field study that allowed the application of the two methods to the operations, and then with the statistical tool ANOVA included in the SPSS computer software, which compares the means of two groups of data to determine whether the results obtained are statistically similar. Finally, with the data obtained, it became evident that there are significant statistical differences between the results obtained with the RULA-RULER and Check List OCRA methods, while measuring the level of risk to which the operatives are exposed and the high possibilities they have of suffering from musculoskeletal diseases.
