متن کاملComparison of Whole-body Vibration Exposures on Older and Newer Haulage Trucks at an Aggregate Stone Quarry Operation
Exposure to whole-body vibration (WBV) and the postural requirements of the job have been identified as important risk factors in the development of musculoskeletal disorders of the back among workers exposed to a vibratory environment. This paper focuses on preliminary results of WBV data collected for two groups of haulage trucks – four older trucks from manufacturer A (MFR-A) and two newer t...
