From the abstract:
Back injuries are common in transit drivers, and can result in substantial direct and indirect cost to the employer and employee. Whole-body vibration (WBV) is one risk factor for drivers. Standards have been adopted (ISO 2631-1) to guide researchers in measuring and analysing WBV levels. Lately, a new standard has been added (ISO 2631-5) that takes impulsive exposures into account….The aims of this study were to determine the levels of vibration for bus drivers using both ISO 2631-1 and 2631-5 standards, and whether there are differences in vibration levels and seat transmissibility between different road types….Conclusions: Bus drivers are potentially being exposed to daily vibration levels higher than recommended especially on certain road types. The current seat in this study does not attenuate the vibration….
