Human Body Vibrations Option
Human body vibrations are mechanical vibrations such as shaking, shocks or jolts. A distinction is made between whole-body vibrations and hand-transmitted vibrations. Human body vibrations occur when a person comes in contact with mechanical vibrations, such as when using vehicles or machines or mechanically operated tools.
Musculoskeletal and circulatory disorders may be caused by vibration. In addition, vibrations negatively impact the well-being and abilities of the person exposed to them.
The Whole-Body Vibration analysis object is used to analyze mechanical vibrations affecting the human body. Whole-body vibrations are caused by vibrations transmitted through the seat or the feet by workplace machines and vehicles.
The Hand-Transmitted Vibration analysis object is used to analyze hand-transmitted vibrations that are transferred from vibrating tools through the palms and fingers to the hands and arms.
The results of the two analysis objects are used to evaluate the risks caused by vibration. The directives and standards include exposure limit values that can be compared to the assessed results. In this way you can determine whether safety measures for eliminating or reducing the effects of vibration are necessary.
