Abstract
A detailed work and medical history was used to calculate whole-body vibration exposure and total vibration dose for a worker appealing a back injury claim. Comparison was made with 3 standards: ISO 2631 (versions from 1978 to 1997); European Economic Community Council Directive; and the German Federal Ministry of Labour. The worker's exposure levels exceeded all standards often by two-fold or more. Total vibration dose (9137) exceeds the suggested by a factor of 6.5-fold. It is concluded this worker's 15-year vibration exposure accelerated the onset, if not caused the L4–5 disc protrusion.
