2 Examination
2.1 Examination by machine operator
Prior to each shift, the machine operator has to examine the
effectiveness of the control and safety devices as well as the
proper fitting of the protection devices.
The safe working condition of construction machinery has to be
checked by the machine operator during operation.
If the safety devices show any defects or if any other defects are
detected that compromise a safe operation, the supervisor has to
be informed immediately.
In case of defects that cause harm to persons, the operation of the
construction machine has to be stopped to eliminate the defects.
2.2 Periodic inspection
Construction machinery has to be inspected for their safe working
condition in accordance with the operating conditions and the
operational requirements as needed, however at least once a year
by an expert.
Pressure vessels have to undergo the prescribed expert
inspections.
The inspection results have to be documented and kept at least
until the next inspection.
