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!

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.

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?

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.

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".

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.

We will describe the principle of this new method which allows to modify the genomes in a targeted way. Thanks to it, it is possible, in a simple and rapid way to neutralize genes or even to add new ones within any living organism. Medical applications are very promising and the mouse model has allowed the cure of genetic diseases like Duchenne myopathy. Pernicious effects reside in the modification of human germ cells leading to new transmissible traits or to the modification of microorganisms in order to make them resistant to antibiotics or to immune system with direct applications in the field of bioterrorism.
Crispr/Cas9 is a new method to manipulate the genome. It promises great advances in the medical field and very positive concrete cases have already been published. However, such scientific progress could be used for less noble purposes.

A single metal oxide can degrade both chemical and biological warfare agents. This oxide, which acts through hydrolysis and oxidation reactions on the chemical agents and via hydrogen peroxide and oxygen-containing intermediates and / or by direct action on the bacterial structures, leads to the formation of non-toxic degradation products because of their small size.
The degradation of paraoxon, a simulant of VX, and some bacteria can be carried out by a magnesium oxide but its effectiveness depends closely on its crystalline structure. The R & D team at Ouvry SAS has just published these results in Chemico-Biological Interactions.
