Impermissible working area
Because of their high manoeuvrability, some placing booms can also
be shifted into positions for which they are not designed. This may
overload or damage the placing boom. Placing booms must therefore
only be moved within the permitted working area.

working area P. 22)
1.1.19.5 Danger zone
The danger zone is the area surrounding the machine, in which peo‐
ple may be at risk of injury from movements required by the work.
The danger zone varies within the working area and depends on the
activity being carried out and the position of the placing boom, if one
is present. Danger zones must be secured and clearly identified. The
machine operator must be capable of seeing the danger zone at all
times and under all circumstances. If necessary, he must appoint a
signaller to supervise the danger zone.
Depending on the working situation, places of work may occasionally
fall within the danger zone, especially the place of work of the hose‐
man and the truck mixer driver. If a place of work falls within the dan‐
ger zone, increased caution is required and suitable personal protec‐
tive equipment is prescribed. Persons who are authorised to be pres‐
ent in such a place of work must use their own discretion to assess
dangerous situations and be able to react according to the situation.
The machine operator is responsible for safety in the danger zone of
the machine whilst the machine is in use.
The machine operator must stop work immediately and press the
EMERGENCY STOP button if an unauthorised person enters the
danger zone.
Support legs and support feet
There is a risk of crushing in the swingout and extension zone for the
supports.
Placing boom
The danger zone when working with the placing boom is the zone
over which the placing boom is slewed. In this area there is a risk of
injury from falling concrete and delivery line components.
