Operation in areas carrying underground
lines
Prior to carrying out excavation work with earthmoving machinery, a check must be
made in the
area to be excavated for underground lines which might present a risk to persons.
If underground lines are present, their location and course must be determined by
agreement with
the owner or operator of the line and the necessary safety measures must be stipulated
and taken.
The course of lines in the construction site zone must be clearly marked under
supervision prior to
earthmoving work being commenced. If the location of lines cannot be determined,
exploratory
trenches must be dug, if necessary by hand.
If underground lines or their protective coverings are contacted or damaged
inadvertently, the
machine operator must stop work immediately and notify the supervisor.
Operation close to overhead electric lines
When working with earthmoving machinery close to overhead electric lines and contact
lines, a
safety clearance dependent on the voltage rating of the overhead line must be kept
between such
lines and the earthmoving machine and its operating devices to prevent a voltage
transfer. This
also applies to the clearance between such lines and attachments or slung loads.
The following safety clearances are applicable in
Germany:
Voltage ratingSafety clearance
up to 1000 V1.0 m
more than 1 kV to 110 kV3.0 m
more than 110 kV to 220 kV4.0 m
more than 220 kV to 380 kV
or for unknown voltage rating5.0 m
6.8.3 All working movements of earthmoving machinery, e.g. the boom positions, the
swinging of
cables and the dimensions of slung loads must be taken into account, as must ground
irregularities through which the earthmoving machine is tilted and thus comes closer to
overhead
lines.
Wind may make overhead lines and operating devices swing out, reducing the
clearance.
If adequate clearance from electrical transmission lines and contact lines cannot be
maintained,
the contractor must implement other safety measures against voltage transfer by
agreement with
the owner or operator of the lines. This may be done, for example, by
- switching off the current,
