Ergonomia aplicada para Kaizen: uso da ferramenta Checklist OCRA para promover melhoria em posto de trabalho em uma empresa do Polo Industrial de Manaus

Abstract

Engineering is responsible for managing and optimizing product processes, while ergonomics is the science that studies the adequacy of the work environment to the employee, aiming to achieve productivity and good adaptation of the human being to their activity, which should be performed quickly and without failures. The study developed seeks to associate the application of ergonomic tools for process optimization with the contribution of engineering, by reducing the factors that contribute to the probability index of illness due to repetitive strain. This index is measured by a percentage range established by the OCRA (Occupational Repetitive Actions) Checklist methodology. The objective is to promote improvements in the operating method and layout, generating results in activity efficiency, cost reduction, and agility in implementing improvements. The use of the ergonomic tool to measure the likely level of employee illness makes it possible to identify lowcost factors that can be solved internally within the company, fostering interaction between the human factor and the organizational/productive factor. The result obtained was made possible thanks to the identification of critical factors that contribute to the increase in the score on the OCRA Checklist. The data evaluated with the ergonomic tool, after workstation adjustments, showed relevant results regarding the proposed changes, reducing the tool's score and changing the ergonomic risk classification from moderate to low. Furthermore, the improvement facilitated the employee’s tasks and reduced the number of complaints.
