Background: Excessive vibration is one of the harmful agents in the work environment, and many drivers are inevitably exposed to that during driving. Objectives: Using ISO 2631-1&5 standards in the present study, the evaluation of the whole-body vibration (WBV) exposure was carried among Tehran metro drivers. Methods: In this descriptive cross-sectional study, 23 trains were investigated and the level of exposure to vibration during daily working shift and vibration indicators were evaluated. According to ISO 2631-1, the following 5 factors were measured: the rate of frequency-weight acceleration r.m.s for each axis, the combination of axes, crest factor, peak acceleration, vibration dose value (VDV), and recent equivalent static compressive stress (Sed) and risk (R) factors -estimation criteria for damage to lumbar spine. Results:The results indicated that based on the basic method, the levels of drivers exposure to the vibration are less than the lower limit set by health guidance caution zone (HGCZ), and according to the VDV methods, 4 cases were found to be above the upper limit, 8 cases were within the HGCZ, and the rest were less than the mentioned limit. Moreover, according to the Sed method, 4 drivers had exposures below the lower limit, 7 had exposures within the range of HGCZ, and 12 of the mover the limit. On the other hand, on the basis of R factor, the levels of exposure of the 3 drivers were within the range of HGCZ, while the rest of them experienced the levels lower than that. Conclusions:The results showed that there are several differences among the calculated criteria confirming that some of these indicators may not show a safe limit.

Abstract. This paper analyses the influence of whole-body vibrations on human performance; for this it was investigated how a group of men (20-29 years of age) and a group of woman (21-31 years of age) answered to specific requirements after being subjected to vertical vibrations under controlled laboratory conditions for 10-25 min. The vibrations were generated by a vibrant system with known amplitudes and frequencies. Accelerations were measured with NetdB -complex system for measuring and analysing human vibration and they were found in the range 0.4 -3.1m/s 2 . The subjects' performances were determined for each vibration level using specific tests. It can be concluded that exposure to vibrations higher than those recommended by ISO 2631 significantly disrupts how subjects responded to tests requirements.

“…The European parliament and the council of the European Union issued "DIRECTIVE 2002/44/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL OF 25 June 2002" 2) . It states that "the member states shall bring into force the law, regulation and administrative provisions necessary to comply with this Directive no later than 6 period shall be 1.15 m/s 2 or, at the discretion of the member state concerned, a vibration dose value of 21 m/s 1.75 ". These values have become a point of focus since passage of the Directive gave it the force of law.…”
