And we talk about smallpox again! BCRNe agent

Publiée par François Renaud le 26 July 2017

In 2002, it was a strain of poliomyelitis virus that had been "artificially" synthetized in the laboratory. Its size is 30 times smaller than the smallpox genome but it took only 15 years to overcome technical problems and to fully synthesize the genome of the equine smallpox virus. Bad news ? Maybe yes if the strain falls in malicious hands. Maybe not if it allows to create new vaccines and / or to develop anti-cancer drugs.

The genome of the dangerous virus of smallpox has just been synthesized thanks to the techniques of synthetic biology. What have we to think about it ?

Self-decontaminating CBRNe outfits

Photocatalysts are elements able to destroy the organic substances which are in their contact under the only action of UV rays, such as those produced by the sun for example. They can therefore be introduced into various substrates which can be self-cleaning: industrial applications have difficulties to develop. On the other hand, introducing them into a protective textile (functionalized textile) which can then neutralize the toxic products without external intervention is a real challenge on which Ouvry SAS has worked hard.

We will briefly describe the mechanisms of photocatalysis that allow textiles to destroy the organic matter that is in contact with it. Ouvry put a lot of hard work in this research through 2 research programs: SELDEC and SAFECOAT.

OUVRY and BBI Detection launch DECPOL® Decontamination Mitt

Publiée par Damien le 21 June 2017

Thanks to the opportunity of the IAFC Hazmat of Baltimore (June 15-18/17), a first-responder’s conference, OUVRY partners with BBI Detection to introduce DECPOL to US decontamination specialists.

DECPOL premiere in USA, the launch of the emergency decontamination mitt!

Chemical weapons (NRBCe) are also the source of therapeutic weapons

Publiée par François Renaud le 31 May 2017

Dangerous chemical weapons have been diverted from their destination for use in therapeutics. There is always concern that the results of scientists’ research may be used for inappropriate purposes, such as terrorism. Here we have the inverse example of the transformation of highly toxic molecules into drugs with controlled toxicity, which are very useful in the field of cancer chemotherapy. It is indeed yperite that gave birth to the first drug against cancer! As for the organophosphates, to dissect their mode of action allowed us to develop drugs against Alzheimer’s disease or glaucoma.

We describe here the processes that led scientists to synthesize very useful anti-cancer drugs from highly toxic molecules used as chemical weapons during conflicts.

Is plague coming back ? (BCRNe)

Publiée par François Renaud le 10 May 2017

Several recent scientific articles refer to plague.
Should we wonder about a possible return of the disease as a re-emerging disease? As a biological weapon? Or by malicious terrorist use?

The plague is still present in everyone’s memory. It has wreaked havoc in previous centuries and it is hard to imagine that one in two people died! But this disease has not disappeared from the surface of the earth and it still kills. Numerous attempts have been made to make it a biological weapon: can it be used in the context of terrorist acts?

Protection against Toxic Industrial Chemicals Hazards (CBRNe)

Publiée par François Renaud le 28 April 2017

The industrial chemical toxics are generally in the form of liquids associated with varying levels of saturated vapor or gas. They are similar to chemical warfare agents. The Polycombi® CBRN Protective suit presents an excellent protection against chemical warfare agents (HD, GD ...). We tested it for its ability to protect against industrial products like hydrofluoric acid and chlorine and to resist a liquid projection of concentrated acid, sometimes intentionally used against law enforcement during demonstrations.

The chemical industry uses highly toxic products which, when released, usually accidentally, can pose a serious threat to the on-site staff and then to first responders. After having defined the main toxic industrial chemicals, we will see how to protect against them.

The main chemical weapons: a brief review (CBRNe)

Publiée par François Renaud le 20 April 2017

In spite of the treaties prohibiting chemical weapons and their destruction, we hear every day about their use on operating grounds: chlorine regularly spread in Syria, sarin gas during the attack of 4 April 2017 on Khan Cheikhoun, Syria, Vx gas deposited on Kim Jong-nam’s face, a half-brother of North Korean leader Kim Jong-un, who was killed on 13 February 2017 at the Kuala Lumpur airport.

In this short article we recall the properties of the main products which are called "chemical weapons".

Thermophysiology and its applications in BCRNE

Publiée par François Renaud le 10 March 2017

Clearly we know that there is an antagonism between the individual protective capacities against liquid and gaseous chemicals and the regulation of body temperature: by preventing liquids and gases from entering, the clothing disrupts the regulation of body temperature. Then, the wearer of the suit is in danger.

What are the solutions ?

We describe in this section how clothing can both protect against extremely toxic chemical liquid and gases and in the same time allows the regulation of body temperature.
