2.1 Main safety precautions
2.1.8 Machine operation at unclear working areas
The machine operator may not operate the machine if he does not have a sufficient overview of the workplace and potential obstacles
are not clearly visible. In such cases, a different efficient form of connection between the appointed worker and the machine operator
must be ensured.
Before putting the machine into operation the machine operator must be informed by the machine user about potential obstacles, e.g.
distribution lines of gas, potable water, pipelines, sewerage, electrical and telephone lines, both aerial and ground ones. These routes
must be properly set out and marked by respective authorities according to national regulations before starting the operation of the
machine.
To ensure connection between the appointed worker and the machine operator, we recommend using hand signals.
2.1.9 Manual signals
The machine operator may not operate the machine if he does not have a sufficient overview of the workplace and potential obstacles
are not clearly visible. In such cases, a different efficient form of connection between the appointed worker and the machine operator
must be ensured. To ensure connection between the appointed worker and the machine operator, we recommend using hand signals.
Hand signals for the machine operator may only be given by persons who:
• are trained for these purposes,
• have proven participation in such training,
• can furnish a certificate of such activity to the user.
When using hand signals, the following principles must be adhered to:
• signals between the appointed worker and the machine operator, given by hand, can only be used in cases when environmental
conditions enable visual contact,
• the machine operator must be trained in the used signals before putting the machine into operation,
• during the operation of the machine only a limited number of signals must be used to avoid any misunderstanding between the
appointed worker and the machine operator.
