Noise and vibration load of lumbermen

Marjan Lipoglavšek ; Biotechnical Faculty, University of Ljubljana, Ljubljana, Slovenia

Sažetak

At eight lumbering sites in Slovenia the noise load of lumbermen working with new and used motor saws was investigated by noise measurements at the ear level. A major contribution to the noise load (Leqv =96-100 dB(A) came from motor saw operations such as limbing. Lumbermen are overloaded with interrupted noise for 25 per cent of their working time. The noise produced by a used motor saw exceeds the noise coming from a new one by 0.7 dB(A). Results of a pilot research into the lumbermen's vibration load generated by Husqvarna 266 and 254 motor saws are also presented. The measurements involved three cutting sites and four lumbermen for six days. The vibration load during the working hours ranged between 6.6 and 10.8 m/s-2. Owing to the fact that vibrations are interrupted and the exposure does not last throughout the working day, the vibration load does not reach a level which would be detrimental to lumbermen's health.
