Division 2.1 Work equipment control devices which affect safety must be clearly visible and identifiable and appropriately marked where necessary.

Except where necessary for certain control devices, control devices must be located outside danger zones and in such a way that their operation cannot pose any additional hazard. They must not give rise to any hazard as a result of any unintentional operation.

If necessary, from the main control position, the operator must be able to ensure that no person is present in the danger zones. If this is impossible, a safe system such as an audible and/or visible warning signal must be given automatically whenever the machinery is about to start. An exposed worker must have the time and the means quickly to avoid hazards caused by the starting or stopping of the work equipment.

Control systems must be safe and must be chosen making due allowance for the failures, faults and constraints to be expected in the planned circumstances of use.
