| Abstract |
Noise exposures and whole-body (WBV) and hand-arm (HAV) vibration exposures were evaluated from 43 forestry workers. Data were collected on ten days over eight weeks during various felling, logging and log handling operations. Five volunteers were also monitored for noise and vibration daily using data logging noise dosimeters, which provided daily time-weighted averages (TWAs) and 1-min averages, and a precision sound level meter equipped to measure human vibration, which provided triaxial HAV and WBV event-weighted averages (AEQs). Workers completed a short questionnaire throughout the workday detailing the timing and number of tasks performed and equipment used. Substantial overexposures to noise and vibration were observed. Noise TWAs according to OSHA and NIOSH exceeded 85dBA in 60% and 83% of the cases respectively. 33-53% of the axis-specific HAV AEQ exceeded the 8-hour ACGIH HAV threshold limit value, and 34% of all WBV AEQs exceeded the 8-hour exposure limit set by the Commission of the European Communities. |
