Historical Collection Protected by WAGNER's Extinguishing Technology
WAGNER protects the wet and dry collections of the Museum für Naturkunde in Berlin from fires since the reconstruction 2010. The fire protection expert installed aspirating smoke detectors for early fire detection and the FirExting® gas extinguishing system.
To ensure that the animal specimens in the Museum für Naturkunde in Berlin are reliably protected, WAGNER worked with the fire department and experts to develop a sophisticated fire protection concept for the seven extinguishing areas ranging in size from 68 to 2,976 m² on different floors. Thanks to highly sensitive and false-alarm-proof fire detection, countermeasures can be taken at an early stage in the event of fire detection. The automatic gas extinguishing system, which is also inconspicuous to museum visitors, ensures immediate containment of the fire without causing consequential damage to the exhibits. Fire extinguishing with inert gas provides comprehensive protection for the valuable collection.
The design of the inert gas fire extinguishing system was carried out in accordance with the EN standard for stationary fire-fighting systems ISO 14520 (EN 15004-1) taking into account NFPA 2001 as well as in extracts according to the guidelines of VdS Schadenverhütung, Cologne, Fire extinguishing systems with non-liquefied inert gases and BGR 134/ BGI 888 (published by the Verband der gewerblichen Berufsgenossenschaften).
The Museum für Naturkunde in Berlin is not only one of the largest natural history museums in Germany, but also an important natural history research institution. Around 30 million animal specimens of inestimable scientific and cultural value are collected here for research purposes. The Museum für Naturkunde in Berlin houses scientific collections of mineralogical, geological and zoological objects. National and international scientists value the holdings at the museum. Whether snakes, snails, lizards, frogs, spiders or fish: some of the animal specimens are more than 200 years old and are used to research the history of life's development.
After part of the museum was destroyed during World War 2, the Museum für Naturkunde in Berlin was rebuilt in 2010. Museum visitors can admire the historic, unique wet collection of alcohol-preserved animal specimens on the first floor of the east wing and thus gain an authentic insight into the research work.
Gas Extinguishing System Protects History Exhibits from Fire Damage
During installation, the fabric of the building should be preserved as much as possible, as should the aesthetics of the rooms for visitors.
Individual and Holistic Fire Extinguishing System for Multiple Areas
Highly sensitive and false-alarm-proof air sampling smoke detectors of the brand TITANUS®detect smoke at a very early stage and thus provide a time advantage in the fight against fire.
After detection, the fire detection control panel switches off the room ventilation and the protected area is flooded with extinguishing gas. The FirExting® gas extinguishing system extinguishes quickly and without residue. The extinguishing gas is stored underground in a separate fire extinguishing system control centre. It is fed into the areas to be protected through pipelines. The pipelines run concealed in ducts and shafts, and the extinguishing nozzles in the SILENT version are also hidden underneath the ceiling and shelves behind protective and baffle plates. Pressure relief flaps ensure optimum distribution of the pressure in the room so that the valuable glasses with the exhibits cannot topple over. A hold time is provided to prevent backfiring.
