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

Joint press release

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: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
