Vibration hazard
Whole-body vibrations
The acceleration data given below for the three directions were measured in
accordance with Directive 2002/44/EC of the European Parliament and
Council. According to this directive the following shall be taken into
consideration for risk assessment:
•
Extent, type and duration of exposition as well as limit values
•
All impacts on the health and safety of the roller driver
•
Information provided by the roller manufacturer
The following represent typical ground compaction activities with and without
vibration. The impact duration shall be taken into consideration when
calculating the daily exposition.

The acceleration data are dependent on the methods used and the ground
properties; that is, the values may deviate from those given.
The actual exposure can be determined using a whole-body vibration
exposure calculator.
