Work-Relatedness and Threshold Limit Values for Back Disorders due to Exposure to whole Body Vibration

Threshold limit values (TLVs) for exposure to occupational whole body vibration (WBV) are proposed based on a review of epidemiological literature and of standards and guidelines available. When TLVs are applied to exposure data for various heavy equipment reported in the literature, conclusions are made about the likelihood of various equipment types contributing to occupational back disorders due to exposure to WBV.
