Abstract

Forest harvesting operations as heavy and dangerous work requires abnormal, uncomfortable working conditions, exposure to noise and vibration, which has adverse health consequences and may lead to illness and injury. Vascular abnormalities, such as the Rhinoceros or White Hand phenomenon (VWF), are known to be the most important, most dangerous, and most common effects of vibration. The purpose of this study was to determine the permissible time limit for vibration exposure during operator exposure to echomotor vibrations in evacuation of evergreen, poplar and alder trees (VWF) in Kheyrud Nowshahr training and research forest in Mazandaran province. Measurement of the time limit index of the governor indicated that the maximum exposure time (hour) for the operator during vibration was 2.59 hours for the whole tree. Therefore, maximal timing workers can partially prevent diseases and injuries caused by vibration motors. According to the results, since the amount of clock exposure the vibrator worker has in the bibliographic mode is higher and the prediction time of the white-handed disease in the rotor worker is greater, therefore, if one is in the binary phase Working two hours a day, evangelical worker has to work with saw for a maximum of 9.61 hours during the week, which is 14/34 hours for poplar and 18/01 for alder. Accordingly, the more hours an ohmicor worker was exposed to in one day and the more the ohmicorum's total vibration increased, the operator had to wait less time than the saw during the week to prevent white-handed disease (VWF).
