Abstract
The European Union Physical Agents Directive (vibration) sets vibration
exposure limits for an employer. The measured values from different work
phases should be time weighted and summed together to represent a daily
8-hour exposure value. The directive has two limit values, the daily
exposure action value and the daily exposure limit value. For the
employer the greatest concern is to comply with the exposure limit
value, but also exceeding the action value will cause implications. To
calculate the daily 8-hour value is not a simple task, because there are
normally several different work phases that the worker does in a normal
day. Also the assessment of measurements of the vibration levels have
to be made in real working environments. The work phases need to be
calculated correctly to get the representative daily value. Also breaks
and other non-work operations need to be included. This will make the
complete assessment very difficult without proper knowledge. In this
study a large number of measurements from different mobile work machines
were made to establish whether the daily values would exceed the limit
values. Analyses were made using three examples to show how the employer
can use the standard and directive to assess the daily exposure values
or times. The results were largely dependent on the work pattern and the
dominant levels.
