Abstract
The standard for ergonomics sets parameters for the working conditions to the psychophysiological characteristics of workers to provide comfort, safety, and efficient performance. The machine-man-task system approach allows the voice of the worker to be included in the design of the production system, the steps of implementation and validation. The aim of this work is to assess the tasks of postal workers in their jobs and propose suggestions to minimize the risks of accidents, injuries and illnesses. The approach used has four ergonomics phases: diagnosis, assessment, design, and validation. The diagnosis showed that levels of illuminance, effective temperature, relative humidity, ventilation, and fire extinguishers coverage met the requirements of standard. The noise level and comfort according to anthropometric measurements didn’t met the requirements of the standard. The ambulation of workers was excessive. A new layout ran for ambulation reduction and validated by the workers as well as labor gymnastics.
