1. An arrangement for protecting against unauthorized intervention in a containment through an access present in a port flange using a work glove, wherein:
a) the port flange is installed in a front window or in a wall of a housing of the containment positioned in an installation space;
b) the work glove is installed on the port flange and allows an operator to enter a work chamber of the containment in a protected manner;
c) in the event that multiple port flanges are installed on the containment, there is one work glove fastened to each port flange;
d) equipment for processing a material to be treated can be provided in the work chamber; and
e) to temporarily block access, a shut-off part is provided, which can move into a blocking position and an open position, the shut-off part is integrated directly in the port flange and can be formed in a pivotable, stretchable, shutter-like or expandable manner, and in the configuration as a closure body integrated in the port flange, and the port flanges are each provided with a safety sensor, the two pairs of safety sensors are used, in cooperation with an external safety relay, to detect the position of the shut-off part in the port flange and, when the shut-off part is open, to activate an automatic blocking of the equipment, wherein
f) to record personal data of the operator, a capture unit is provided, which has a connection to a microcontroller, in order to issue a switching command to an activator if there is correspondence between the captured personal data and the data in the microcontroller, whereby the shut-off part can be brought into the blocking position or can be moved therefrom into the open position and therefore the access is blocked or accessible, respectively;
g) the activator is arranged directly on the port flange or on the shut-off part or on the front window; and
h) the data of the microcontroller are stored directly therein or originate from an external control unit.
