Ergonomic workplace analysis (EWA) as a model for creating an instrument to assess rest locations for truck drivers

INTRODUCTION: The relationship between sleep quality and rest location is rarely explored in the literature. In this context, ergonomic analysis instruments can contribute with information for a satisfactory rest environment throughout the work schedule. OBJECTIVES: To analyze the performance of an instrument based on Ergonomic Workplace Analysis for assessing rest locations. METHODS: This study adapted an ergonomic instrument to a new purpose. To analyze its performance, we assessed the rest locations of truck drivers working for a large transportation company located in the state of São Paulo. RESULTS: The variables adapted from the original Ergonomic Workplace Analysis were rest location, sequence of tasks, lighting, noise, indoor comfort, and thermal comfort. Photos and flowcharts were used to better describe the data. CONCLUSION: The new instrument was shown to be adequate for assessing rest locations. The drivers evaluated the accommodations more positively than the analyst, and truck sleepers and company accommodations were considered different both by the drivers and the analyst.
