COLD, VIBRATION, AIRBORNE EXPOSURES AND SOCIO-ECONOMIC INFLUENCES IN MINING

About vibration

Many workers in the mining industry experience work-related vibration. For example, maintenance workers use hand tools that create vibration and truck driver are exposed to vibration in their vehicles. An operator of hand tools experience vibration in their hands and arms and vehicle operators experience vibration in their whole body. Therefore, occupational exposure to vibration is subdivided in to two main categories: hand-arm vibration (HAV) and whole-body vibration (WBV).

Exposure to hand-arm vibration.                   Exposure to whole-body vibration.

 

Acceleration is the magnitude usually used to describe the exposure to vibration (unit m/s2). The exposure time, the total time during which the vibrations occur, is highly significant when assessing effects on humans. Therefore, the daily exposure to vibration is expressed by means of the vibration magnitude and daily exposure time as the daily A(8). The daily exposure (A(8)) is used for comparison with stated governmental exposure limit values and action values for vibration.
