Security means also protection from not authorized access. Access to the Biobank rooms is then kept under strict surveillance. Only the system operators are allowed to enter, but not before being identified by a biometric system. In practice, they are recognized by their fingerprint hedged in the memory of the surveillance computer.

For Moli-bank, personal safety is important as well. All operators must wear special gowns, masks and gloves to protect themselves from the tanks hard cold and from possible liquid nitrogen drops that might reach them during loading operations or samples extraction. In addition, nobody is allowed to operate on his own in the Biobank: is compulsory the simultaneous presence of at least two people, while a camera continuously films the rooms, allowing operators to keep under control the ongoing operations. Finally, liquid nitrogen escape might saturate the air, lowering the oxygen in the air and laying the operators lives on the line. That is why oxygen levels are constantly kept under control by two sensors able to give the alarm whenever needed.
It is important to note that Moli-sani never goes on holiday. All parameters, instrumentations and alarms are kept under control by operators, even when they are not in the laboratories. Thanks to safe data transmission connections, operators are able to intervene from a distance to modify some characteristics of the system in order to detect immediately the anomalies that may occur.
