The number of attacks on cash dispensers in banks has considerably increased during the last few years. The perpetrators usually use explosive gas mixtures, which are locally produced from individual high-risk gases and channelled into the safe. Gas explosions in the cash dispenser safe are difficult to control and exhibit a large destructive potential.
Ruined or burned-out bank offices, destroyed cash dispensers and looted cash are the usual results. Perpetrators sometimes suffer serious injuries as well because they have underestimated the strength of the explosion or the explosive mix ignites too early.
In order to equip cash dispensers against such attacks, the Federal Institute for Materials Research and Testing (BAM), commissioned by the VdS, has carried out a series of systematic explosion tests on different types of cash dispensers at BAM's open-air test facility in Horstwalde (Brandenburg).
This facility - which is unique in the Federal Republic of Germany - enables explosion tests using volatile gases the same as those used in the past by the criminals. The cash dispensers were equipped with pressure and temperature sensors to measure the impact of the explosions on the material of the safe. High-speed video photography enabled an exact analysis of material failure.
In order to prevent cash dispensers from being blown up in the future, preventive measures such as amended design of the safe or the use of gas sensor alarms can be prepared.
BAM and VdS intend to co-operate in this special field of public safety in the interest of avoiding future damage to property and people. In addition to further practical investigation, design modifications relating to the specific risks should be discussed with all manufacturers of high-value containers.
The first VdS-recognized safety measures are expected shortly: a dye system, which indelibly marks the notes and makes them very difficult or even impossible to use. VdS presented a test agreement which describes the specifications of design improvements required for high-value containers to resist gas attacks at the annual burglary-theft conference on 30 and 31 May 2007.Contact:

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
