Whole body vibration measurements equipment and procedure. Limit the time spent by workers on a vibrating surface.
Pdf Assessment Of Continuous And Impulsive Whole Body
Whole body vibration measurement equipment. Whole body vibration measurement. Ensure that equipment is well maintained to avoid excessive vibration. Mechanically isolate the vibrating source or surface to reduce exposure. The pce vm 31 hawb human vibration meter is designed for measuring human vibration at the workplace. Whole body vibration what is whole body vibration. Measurements were obtained using an ios application wbv v22.
Exposure to whole body vibration wbv negatively impacts the health and safety of exposed mine workers. Whole body vibration generally results from plant operators such as earth moving equipment truck drivers airplane helicopter pilots crane and train drivers and the like whereby their whole body oscillates up and down side to side and or back to front or a combination of these. The initial phase of the research focussed on obtaining long duration measurements of whole body vibration during normal equipment operation. Simultaneous 3 channel measurements of the x y and z vibration levels plus the vector sum using the relevant weighting curves. Drivers of some mobile machines including tractors fork lift trucks and quarrying or earth. For health and safety evaluations this is through the buttocks and feet of a seated person or the feet of a.
Install vibration damping seats. The following precautions help to reduce whole body vibration exposure. Whole body vibration wbv is transmitted through the seat or feet of employees who drive mobile machines or other work vehicles over rough and uneven surfaces as a main part of their job. Vibration is often complex contains many frequencies occurs in several directions and changes over time. Whole body vibration is applicable to motions transmitted from workplace machines and vehicles to the human body through a supporting surface. Human exposure to whole body vibrations should be evaluated using the method defined in iso 2631 11997.
Who can suffer from whole body vibration. Consequently relatively few measurements of whole body vibration are routinely undertaken at underground coal mines. Off road mining equipment operates on rough surfaces under harsh operating conditions that produce wbv and mechanical shock. Large shocks and jolts may cause health risks including back pain. Sufficient whole body vibration measurements at underground coal mines to manage exposure to the hazard has previously been difficult because of the complexity expense and relative fragility of the measurement equipment. Front end wheel loaders along with haul trucks show the highest number of injuries related to jarringjolting and whole body vibration.
The vibration meter can calculate hand arm vibration measurements according to iso 5349 and whole body vibration measurements according to iso 2631. Negative health effects of exposure to whole body vibration are prevalent in the industrial world today particularly where heavy earth moving equipment and off road vehicles are necessities. Designed specifically for the measurement of whole body vibration and the vibration dose value.
