Abstract
Studies are developed in order to characterize and evaluate exposure to Whole Body Vibration (WBV) through individual components, that is, by decomposing daily exposure into parts. The standard responsible for the parameterization of WBV exposure is NHO - 09 – Avaliação da Exposição Ocupacional a Vibrações de Corpo Inteiro (2013) based on the International Organization for Standardization (ISO) - 2631: Mechanical vibration and shock - Evaluation of human exposure to whole-body vibration. Part 1: General Requeriments (1997). Although the NHO - 09 presents detailing to obtain the evaluation parameters aren and VDVR, there is not standardization to obtaining the individual components needed to obtain them. The NHO - 09 indicates a professional analysis on the evaluator responsible for the study regarding the amounts and duration of the individual components used, which may present divergence from evaluator to evaluator as a result of the amount of data obtained. This study consisted on a comparison on the interference of the quantity and the measurement time of the components used for evaluations to WBV exposure. Through four analyzes with different amounts of individual components and with or without repetitions, the coherence between the four results obtained in relation to WBV exposure of a school bus driver of the University of Brasilia (UnB) was evaluated. It could be concluded that for this study that has fixed daily paths, it is possible to evaluate the exposure to WBV through the use of exposure components.
