Abstract (EN):
Urban bus drivers are exposed to mechanical vibrations which are transmitted to the whole-body and have effects on health of the workers. The aim of this study is to evaluate Whole-Body Vibrations (WBV) among urban bus drivers, relating vibration magnitude with the road characteristics. A study of seat’s transmissibility is also presented. Were used the methodological recommendations of ISO 2631-1 (1997) and ISO 2631-5 (2004). Three routes, with three different drivers to collection data were defined. All drivers were exposed to values lower than exposure and action limits. So according the standards, the probability of health effects is low. The seats have also a positive effect reducing the transmission of the WBV to the driver in all cases. The workers are not exposed to highest values than exposure limits, but some preventive strategies were recommended. Despite the improvement of urban pavements is not an enterprises responsibility, its evaluation and improvement is suggested. © 2015 Taylor & Francis Group, London.
