SYNOPSIS Whole-body vibration (WBV) exposure measurements taken from 105 truck drivers employed in 19 mines and other workplaces were evaluated with the criteria prescribed in EU 2002/44/EC directive, BS 6841 (1987), ISO 2631-1 (1997). and ISO 2631-5 (2004) standards. The highest vibration acceleration was measured on the vertical Z-axis. The highest WBV exposure occurred in the RETURN, HAUL, and SPOT phases while the lowest exposure took place in the LOAD and WAIT phases. Crest factors on all axes were generally greater than nine, yet strong correlation coefficients were achieved in VDV-eVDV analyses. Driver seats generally dampened the vibration along the Z-axis but exacerbated it along X and Y axes. The dominant frequency for the X and Y-axes rose up to 40 Hz while it ranged between 1 Hz and 2.5 Hz along the Z-axis. While the probability of an adverse health effect was higher with BS 6841 (1987) and ISO 2631-1 (1997) standards, it was low according to EU 2002/44/EC and ISO 2631-5 (2004). The 91 t, 100 t, and 170 t capacity trucks produced lower vibration magnitudes. Drivers were exposed to approximately equivalent levels of WBV acceleration and dose in contractor-type trucks and mining trucks. Rear-dump trucks exposed their drivers to a slightly higher level of vibration than bottom-dump trucks. Underground trucks exposed their drivers to a significantly higher level of vibration than mining trucks. Both driver age and driver experience were inversely proportional to vibration acceleration and dose. Conversely, there was a positive relationship between the truck service years and the WBV acceleration and dose to which drivers were exposed to. Loads of blocky material exposed drivers to higher vibration acceleration and dose levels than non-blocky material.

Daily Exposure

Exposure to whole body vibration (WBV) is known to be associated with various adverse health outcomes among professional truck drivers. As a part of a randomized controlled trial, this study evaluated WBV exposures and various health outcomes from 96 professional truck drivers. The WBV was measured and analyzed per International Standards Organization (ISO) 2631-1 and 2631-5 WBV standards. This study also measured self-reported regional body pain (10-point scale), low back disability (the Oswestry Disability Index), and physical/mental health (the Short Form 12-item Health Survey). Lastly, this study evaluated associations between the WBV exposure and various health outcomes. The results showed that the predominant z-axis weighted average vibration [A(8)] measure (Mean ± SE: 0.35 ± 0.01 m/s2) was below the ISO and European Union (EU) daily exposure action limits (0.5 m/s2) whereas the vibration dose value [VDV(8)] measure (12.2 ± 0.3 m/s1.75) was above the ISO and EU daily exposure action limit (9.1 m/s1.75). Self-reported low back pain (LBP) was the most prevalent adverse musculoskeletal outcome reported (72.5%) with average LBP score of 2.9 (SD: 2.0). The SF-12 health scores showed that truck drivers’ physical health status was lower than the average US population (p’s < 0.04). Moreover, the Spearman’s correlations ( rs ) between the WBV parameters and health outcomes indicated that A(8) measures were associated with LBP ( rs = 0.31; r = 0.05) and SF-12 physical composite score ( rs = −0.39; r = 0.02); however VDV(8) was not associated with any of the health outcomes. The study findings indicates that although the impulsive exposures [VDV(8)] were more prominent, the continuous, average vibration [A(8)] appears to be more strongly associated with injury risks. This finding supports the practice of EU countries using A(8) as one of the primary measures for characterizing daily WBV exposures but also complements many other studies indicating that the current EU daily action limit value of 0.50 m/s2 for WBV may be too high.

Abstract Background: Most occupational diseases do not fit the paradigm of medical interpretation of the health-disease process based on linear causality, in which it would be possible to find a single cause for each type of disease. Objectives: to conduct a systematic review in order to investigate the association between whole-body vibration (WBV) and musculoskeletal disorders (MSD) in professional truck drivers (PTD). Methods: The scientific databases of PubMed, Cochrane, Lilacs and Scielo were used to collect articles published from 2000 until the present time. Two independent reviewers adopted inclusion and quality criteria to evaluate the selected articles. Results: From adopted inclusion and quality criteria, nine articles were chosen to identify the association between MSD and WBV in PTD. The results showed that MSD seems to be closely associated to exposure to WBV in these workers, mainly due to high prevalence and symptoms of low back pain. Two cohort studies showed exposure to WBV as risk for MSD. Only one, with case-control design, did not show WBV as a significant factor. Conclusions: In this study the importance of exposure analysis of WBV in the occurrence of MSD in PTD was elucidated. This study showed the importance of WBV exposure analysis on the occurrence of MSD in PTD. There is adequate information to provide rationale for the reduction of WBV exposure to the lowest possible level, to ensure the health of these workers. Studies with a greater power of investigation, of a prospective, design, should be encouraged, supplanting those only of association.

Drivers of mining dump trucks are a group of highly qualified specialists whose training requires considerable time and financial costs. We investigate the working conditions, general and occupational pathology of the dump truck drivers of the open apatite mines in the Arctic. We carried out the analysis of working conditions and health status of 475 dump truck drivers and 534 miners of other occupations of open apatite mines, as well as the information on the occupational pathology of that workers group in 2007–2017. It has been established that the typical feature of health disorders in the dump truck drivers is the frequent development of obesity (22.9 % of workers), and occupational pathology which is in most cases due to imperfect technological processes (67.3 %), leading to an increased severity of labor and exposure to whole-body vibration. The most prevalent occupational diseases of drivers are vibration disease (36.5 %), radiculopathy (25.8 %) and mono-polyneuropathy (20.1 %). The risk of occupational pathology among truckers is higher than that one for miners of other specialties: RR = 1.35; DI 1.04-1.74. Measures aimed at health preservation of dump truck drivers should include the correction of food and work regimes, the improvement of technological processes during the transportation of ore raw materials targeted at reducing the severity of labor and harmful effects of whole-body vibration.
