Access to the IT area (protection zone 3) or to the entire security area (protection zone 2) is gained by effectively implementing the separation of persons. A combination of technical and organisational solutions, such as video surveillance and remote release of an interlock door, can be used.
Secondary access routes are secured accordingly so that the pedestrian separation system cannot be bypassed.
The need for an interlock system must be derived from a risk assessment. The indicator was not set in the print version.
