Abstract:
This research aims to make a comparative evaluation of three different parachuting harnesses to work at heights in the energy industry, from the electricians' point of view concerning these products under the optics of usability and ergonomic principles, and mainly justified by the high quantity of injuries at the energy industry due to high falls. According to its main target, this field research is classified as exploratory-descriptive transversal viewing study and, considering this perspective, the study was developed in four steps. Research results have enlightened the weakest spots and the potential improvement opportunities of these products, developed to assure safety of the work at heights to the energy industry, according to the opinion of the users. Still, results point that, regardless of the model, these devices have adapting issues to fulfill the electrical sector user's needs.
