Working in the vicinity of overhead power lines
When working with the machine in the vicinity of overhead power lines and tram lines, a minimum distance as
specified in the following table must be maintained between the machine and its attachments and the power line.
The owner of the machine or the person responsible for the work must ensure local, regional and national regula-
tions are observed.
If safe distances can not be maintained, the power lines must be switched off in coordination with their owner or
provider and secured against making them live again.
When approaching overhead power lines, any possible movements of the machine must be taken into consider-
ation.
Unevenness of the ground or sloping the machine can reduce the safe distance.
Wind can cause the overhead power lines to sway, thus reducing the safe distance.
In case of a power cross-over, leave the danger zone with the machine, if possible, by taking suitable measures.
If this is not possible, do not leave the operator’s place, warn any approaching persons of the danger, and have
the power switched off.
Working in the vicinity of underground power lines
Before starting with excavation work, the owner of the machine or the person responsible for the work must check
if there are any underground power lines in the proposed working area. The owner of the machine or the person
responsible for the work must ensure local, regional and national regulations are observed.
If there are underground power lines present, the position and routing of the power lines must be determined to-
gether with the owners or operators and the required safety measures must be determined.
If power lines are encountered or accidentally damaged, the operator must stop working immediately and inform
the responsible person.
