Planning and Preparation
Safety distance
A minimum distance must be maintained between the protection field and the
danger zone to ensure potentially dangerous movements are brought to a stop
before contact with a person is possible.
Figure 4.1
Minimum distance between protection field and hazardous area
This distance is calculated from the lag time of the machine, the response time of
the safety system, and the speed of movement of the person entering the
hazardous area (ISO/EN 13855).
