Hand-Arm and Whole Body Vibrations Measurement

The measurement of human hand-arm vibration (HAV) and whole-body vibration (WBV) is critical to ensuring the safety of workers in industrial plants. HAV and WBV are two types of workplace risk and can cause serious health problems if not properly controlled. HAV are caused by the use of hand-held power tools, while WBV are caused by the use of heavy machinery and vehicles.

As a control body that regularly performs the measurement and control of human vibrations, in this article we will introduce in general the meaning of the HAV and WBV measurement and the procedure for its performance.

Hand-Arm Vibration Measurement

HAV is a common hazard in many industrial workplaces and can cause a number of health problems, including carpal tunnel syndrome, white finger syndrome, and hand-arm vibration syndrome. These conditions can have a significant impact on workers' quality of life and ability to work, and can even end their careers.

Measurement of HAV is essential to identify the level of worker exposure to this hazard. By measuring HAV levels, employers can determine if workers should be provided with alternative tools or if additional safety measures, such as regular breaks, are needed.

Whole Body Vibration Measurement

WBV is another occupational hazard that can cause serious health problems, including back pain, musculoskeletal disorders and spinal injuries. Workers who operate heavy machinery or vehicles, such as forklifts or tractors, are particularly at risk of exposure to WBV.

Measurement of WBV is critical to identify the level of worker exposure to this hazard. By measuring WBV levels, employers can determine if workers should be provided with alternative machines or if additional safety measures, such as impact-absorbing seats, are needed.

How Hand-Arm and Whole Body Vibrations are Measured

HAV and WBV are measured using specialized equipment, such as vibrometers and accelerometers. These devices are attached to the tool or machine in question (or to the hand or body of the relevant tool/machine operator) and measure the vibration levels that are generated during use. The measurements are then used to calculate the HAV or WBV exposure level.

The measurements taken are compared to the established exposure limits set by the relevant health and safety authority in the area. If measurements exceed these limits, employers are required to take action to reduce worker exposure to HAV or WBV.

Conclusion

Hand-Arm and Whole Body vibrations can cause serious health problems for workers in industrial plants. The measurement of HAV and WBV levels is critical to identify the level of worker exposure to these hazards and to develop effective risk assessments and control measures to reduce the risk of injury. Employers must take action to reduce workers' exposure to HAV and WBV to protect their health and well-being.
