Abstract:
In this paper, measurements of mechanical vibrations are carried out at different working conditions by using different tools. Measurements were committed with a 4447-type Human vibration analyzer, with vibrations measured from the source to the receiver. Measurements are made in real time, by using a specific tool, and worker for whom minimization of vibrations at work is needed. Vibrations which can vary in large measure regarding the excitation frequencies and levels can also depend from the employee\'s weight and conduct. The time of exposure to vibrations can be determined with proper measurement in real terms, which is one of the most important factors in preserving the health of the employee. Also, this paper analyses the significance of risk assessment in the process of decreasing the influence of vibrations on the human body.
