The operation of vehicles gives rise to vibration. Workers who drive vehicles at work are consequently exposed to whole-body vibration. The level of exposure may vary according to a number of factors, such as the driving style, the adjustment of the driver’s seat, and the driver’s body posture. It can be very helpful for the workers to be able to place their own perception of the vibration in relation to an external assessment. This makes them conscious of the exposure and enables them to take measures to reduce it themselves, by adjusting their driving style and suitably adjusting the seat. The Institute for Occupational Safety and Health of the German Social Accident Insurance (IFA) has therefore developed a user-friendly vibration exposure display.
This device informs workers of their instantaneous vibration exposure by means of a traffic-light arrangement on the display: should the exposure exceed the limit value, the column appears in red; if only the action value is exceeded, it appears in amber; below the action value, the column appears in green.

Importance was attached during design of the display to its suitability for use in daylight and the ease with which it can be mounted securely in the driver’s cab. The display has a simple single-button control for all functions (switching on, starting measurement, ending measurement, switching off).
The impact of a change in driving style or seat adjustment upon the vibration exposure can be seen immediately on the display. It can also be used for training and instruction purposes.
The whole-body vibration display is available from the IFA on loan free of charge to interested parties through their responsible accident insurance institutions.
