Abstract
The objectives of this study were to compare the levels of occupational whole-body vibration presented by tire and track harvesters, in order to verify if there are significant differences between the two types of machines, and also if such exposure represents a health risk to the operators. Two models of track harvesters and two of tire harvesters were assessed. The assessment was carried out according to the methodology established in ISO Standard 2631-1: 1997 and the results were compared to the reference values of Directive 2002/44/EC. The tire harvesters presented low vibration levels, not representing disease development risk to the operators. The track harvesters presented about 2.3 higher vibration values than those presented by tire harvesters and above the limit of action foreseen in the reference standard, thus actions to mitigate the deleterious effects of vibration on the health of the workers become necessary. Thus, the results of this study allowed us to conclude that track harvesters have significantly higher occupational vibration levels than those presented by tire harvesters; that such values are above the limit of action established by the reference standard; that immediate interventions in machinery and processes are necessary in order to reduce operator exposure to vibration; and that they are exposed to a high risk of developing occupational diseases resulting from exposure to the physical agent vibration.
