Case Study: State Parliament of Lower Saxony

Secure fire protection for data at the government headquarter in Hanover, Lower Saxony, Germany

When a new data center was set up in the State Parliament of Lower Saxony in 2011, WAGNER convinced the decision-makers with its comprehensive fire protection concept consisting of early fire detection, active fire prevention and organization / hazard management system. This ensures security and data availability even in the event of an emergency.

In the Lower Saxony state parliament, an IT failure would cause considerable disruption to internal and external processes or even completely paralyze parts of the administrative and parliamentary group business. In order to be able to guarantee the operational business of the state government, the decision was made to use a fire protection solution from WAGNER.

Invisible to the outside world, the communications threads of the state parliament come together in the underground computer center. Vast amounts of data and information have to be processed and secured here every day. Due to the central importance of the data-center, the monetary and non-monetary losses in the event of a fire can be immense. An effective and uninterruptible IT infrastructure is therefore very important - this also applies to fire protection.

Since 1962, the State Parliament of Lower Saxony has been located in Hanover's Leineschloss. The building was erected in 1637 as a ducal residence. Over the years, it has undergone many additions and alterations. During the Second World War it was destroyed by air raids on Hanover, except for the outer walls. It was rebuilt from 1956 on.

Maintaining IT availability even in the event of a fire

Risk Analysis

Electrical
Defects in electrical e.g. equipment and conductor connections can lead to a fire.
Fire load
Cable insulation, printed circuit boards, enclosures, intermediate floors, insulation, etc. represent a high fire load in the data center.

Protection Goals

Data
The irretrievable data of the Lower Saxony state parliament must be secured against loss by fire.
IT availability
To protect IT availability and its operations, the fire-related failure of the IT infrastructure must be avoided at all costs.
Infrastructure
The infrastructure of the data center and the entire state parliament must be protected in terms of fire protection.
Accessibility
During normal operation, the data center should be freely accessible to employees.
Countermeasures
If necessary, countermeasures should be initiated immediately in the event of early fire detection.

Preventive fire protection in the IT center of the Lower Saxony State Parliament

In addition to active fire prevention by means of the OxyReduct^® oxygen reduction system, the fire protection concept used in the state parliament provides for rapid reduction so that in the event of a fire being detected by TITANUS^® aspirating smoke detectors, the oxygen level in the data center is further reduced within a few minutes by introducing additional nitrogen from extinguishing gas containers. The VisuLAN^® organizational / hazard management system centrally controls the necessary security measures.

In normal operation, the OxyReduct^® fire prevention system reduces the oxygen content to a previously defined level below the ignition limit of critical materials in the protected area and continuously maintains it at this level. The reduced oxygen content creates an atmosphere in the data center that prevents the normal spread of fire.

TITANUS^® aspirating smoke detectors continuously monitor the room air in the protected areas for the smallest smoke particles. The system detects fires very reliably already in the pyrolysis phase, i.e. when smoke is not yet visible and the fire in its early stages is not yet detectable by conventional smoke detectors.

If the TITANUS^® smoke detectors detect a fire, the oxygen concentration in the protected area is immediately lowered further by means of rapid reduction. The nitrogen required for this comes from stored extinguishing agent tanks. By means of an oxygen reduction system, the oxygen level can be maintained without restriction after flooding.

Thanks to networking with the VisuLAN^® organization/hazard management system, all systems and necessary safety measures can be controlled centrally in an emergency.

Customer Benefits

Availability
The majority of IT systems can continue to operate in the event of a fire; it is not necessary to switch off the power.
Early
A developing fire should be detected at an early stage (if possible during pyrolysis phase) in order to take countermeasures as quickly as possible.
Close
Fire detection systems were installed in the IT center as well as directly in the distribution rooms and cable shafts.
Central
In an emergency, all systems and necessary backup measures can be controlled centrally.
Safe
(Trained) employees can enter the data center during normal operation and also after the initial oxygen reduction in case of fire.
