Protection for cash dispensers from being blown-up by explosive gas mixtures

07.08.2007
Joint press release
Federal Institute for Materials Research and Testing (BAM)
VdS Schadenverhütung GmbH

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.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
