The correlation between the methods that calculate ergonomic risk offers a contribution of the most appropriate ergonomic method for the swine chill. In this context, the objective of this study was to correlate the performance of four ergonomic risk factor tools (OCRA - Rapid Upper Limb Assessment, REBA - Rapid Entire Body Assessment and TOR-TOM - Occupancy Rate Real - Rate of Maximum Occupancy) through statistical analysis. The data collection was performed in the courtroom sector through the application of the observational method by filming. The calculated methods were converted to a five-point Likert scale and performed an analysis of variance between groups (ANOVA) and multiple comparison. As a result it can be stated that all ergonomic risks do not present significant differences between the tools, and when the multiple comparison was made, the dynamic methods (OCRA and TOR-TOM) differed from static methods (RULA and REBA). Through linear regression, the dynamic methods were more adequate for the refrigeration workstations. To conclude, the dynamic methods are suitable for ergonomic risk analysis in pigs and can be used by weighing the objectives of analysis, the needs of the work stations, reducing the exposure to ergonomic risk and as a consequence reducing the exposure to musculoskeletal diseases. |
