In recent decades fully mechanised cut-to-length forest harvesting systems have spread from
flat and gentle to steep and rough terrain. To analyse the potential adverse impact of these
changes on operator health, an observational study of exposure to noise and whole-body vibration
(WBV) was carried out in karst terrain. The results showed that, in contrast to exposure
to noise, the exposure of harvester and forwarder operators to WBV exceeds the daily exposure
action value specified in the European Directive. Differences between work sites may contribute
up to 8.7 dB(A) to noise exposure and up to 0.28 m/s2 and 6.0 m/s1.75 to WBV exposure
when working with forwarders and harvesters. Aside from technical upgrades of machines,
reduction of exposure to both WBV and noise, while simultaneously maintaining high productivity,
requires careful selection of work sites and adapted work organisation.
