Análise ergonômica do posto de trabalho pelo método rula: um estudo de caso em uma relojoaria

Abstract

The present study aims to perform an Ergonomic Work Analysis (EWA) in a watchmaking. The research focused on the study of the activities carried out in the work of the watchmaker. To understand the necessary knowledge, a bibliographic survey was carried out on books, articles and websites related to the topic. The case study through the analysis of organizational data, data collection, diagnoses and recommendations. Through the application of questionnaires and space / environment analysis in terms of thermal, acoustic and luminous comfort, it was possible to identify the points that need an investigation. Thus, the workbench lighting and the noise proved to be critical points. Sound intensity measurements were performed in the workspace to ascertain the source of the noise. The analysis of the postures, it was initially identified the operative mode regarding the execution of the activities, and based on the gestures and movements of the collaborator, the Rapid Upper Limb Assessment (RULA) method was applied using Ergolândia 6.0 software to detect the level of intervention required for the postures analyzed. Based on the synthesis of the data collected, the work environment was diagnosed and finally ergonomic recommendations were proposed regarding work space and occupational health prevention.
