Abstract

A thirteen-year prospective study has been conducted of an open cohort of forestry workers, to reconstruct the current vibration exposure using either the ISO frequency weighting, or an unweighted bandpass filter. In this study, methods are described for recording the vibration at the hands, which provide an estimate of the annual exposure when combined with the work history obtained from workers by questionnaire. Day-long vibration exposures at the hands of workers during normal forestry operations were monitored using a compact, custom-built, data-logger based system. The exposures of four forest workers brush cutting, and another four workers tree harvesting, are found. The exposures are reported as 8-hour energy equivalent RMS accelerations for the component directed into the palm.
