Abstract
This cross-sectional study was done aiming at determining the exposure of taxi drivers to vibration on 35 safe taxis (19 cars with engine volume of 1.325 L, 9 cars with engine volume of 1.645 L, and 7 cars with engine volume of 1.761 L). Measurements were based on ‘ISO 2631-1’ on seats’ pans, by Castel GA2005 vibrometer. The results through two different evaluative methods indicated moderate exposure levels, corresponding to suggestive Health Guidance Caution Zone (HGCZ) in ‘ISO 2631-1’. Evaluation of exposure to the WBV among taxi drivers, in the taxis with low and high mean acceleration values, using the VDV method is preferred over the R.M.S method. In lower accelerations, in all conditions, the mean of the reckoned values in the VDV method was less than the R.M.S method, and in higher accelerations, where there are more differences, and the CF values were higher (PAIK 1761 cars), again the assessed mean duration in the VDV method is less than R.M.S method. In higher accelerations and with fewer crest factors, this matter didn’t hold, and the allowed time in the R.M.S method became lower.
