O uso do corpo como instrumento: quando a máquina não oferece as condições adequadas para a execução da tarefa de recuperação de unidades injetoras

Abstract

This study aims to present the experienced constraints and regulations of the work developed and applied by workers performing the recovery unit injectors for engines in a vehicle maintenance workshop, called CRC - Recovery Center Components. Here, the injection units are received malfunctioning, undergo proper maintenance and returned in perfect condition, ready to be installed in your vehicle engine. The result of this study mainly shows the hardiness of the equipment made available to workers who perform the function of the injectors and test how this equipment hinders the implementation of this task, requiring the increased use of physical load and can even lead to these professionals development of work-related diseases. The method used was the Ergonomic Work Analysis (EWA) through its tools that allow a better understanding of the situations experienced by workers. To clarify the situations of work and activities that employees perform as well as the process as a whole, interviews and direct observation of the residence times of different combinations of positions that adopt, running movements were made. In addition, a data collection was performed to identify and record the most important events that contributed to the completion of this study and the recommendations made to mitigate and / or eliminate the main conditions that can compromise the health of these workers.
