Safety instructions for operation of earth moving machines
7.4 Danger zone
7.4.1 All persons must stay clear of the danger zone of the earth moving machine.
The danger zone is the area around the earth moving machine in which persons are at risk
by work-specific movements of the earth moving machine, its work equipment and attach-
ments, by slewing or falling material, or by falling work equipment.
7.4.2 The machine operator may work with the earth moving machine only if no one is in
the danger zone.
7.4.3 The machine operator must give warning signs in case of danger for persons.
7.4.4 The machine operator must stop work with the earth moving machine if persons do
not leave the danger zone in spite of his warnings.
7.4.5 Do not step onto the articulation of articulation-steered earth moving machines if
the engine is running.
7.4.6 Keep a sufficiently safe distance (min. 500 mm) to fixed elements of construction,
for example buildings, walls to be pulled down, scaffolds or other machines to avoid
danger of crushing.
7.4.7 If a safe distance cannot be kept, seal off the area between fixed elements of con-
struction and the work range of the earth moving machine.
7.4.8 If the operator’s visibility onto his drive and work range is impaired by work-specific circum-
stances, instruct the operator or seal off the drive and work range with a fixed barrier.
7.5 Stability
7.5.1 Always use, drive and operate the earth moving machine ensuring stability and
safety from turning over (see also item 7.3).
7.5.2 The operator must adapt his travel speed to the prevailing conditions and lower the
work equipment the closest possible to the ground when driving on sloping or une-
ven terrain.
7.5.3 Follow the instructions given in the specific sections of the Operator’s Manual of the
manufacturer when using an earth moving machine equipped with additional stabi-
lizer legs or supporting equipment for increasing stability.
7.5.4 Keep the earth moving machine at a safe distance from the edges of quarries, pits,
ditches, slopes or embankments to avoid danger of falling.
7.5.5 When driving or working near excavations, shafts, trenches or the edge of pits and
embankments, secure the earth moving machine to prevent it slipping or rolling away.
