Abstract: A method of extracting solid energetic material from contaminated soil including a mixture of energetic material with plant substances, mineral aggregates and metal parts, the method including a sieving and washing of the contaminated soil to recover the mixture and remove the earth and sand possibly present, a first densimetric separation between a light fraction including the plant substances and a heavy fraction including the energetic material, the mineral aggregates and the metal parts, by immersing the mixture thus recovered in a water bath, an extraction of the heavy fraction obtained during the first densimetric separation, a drying or draining of the heavy fraction thus extracted, a second densimetric separation between the energetic material and the mineral aggregates and the metal parts, and extracting the energetic material obtained as a result of the second densimetric separation.

Abstract: A device for neutralizing a chemical or biological weapon includes a sealed enclosure which delimits an internal volume and which is movable between a retracted position and an extended position, a pyrotechnic neutralizing charge which is disposed inside the enclosure, a decontaminating agent which is disposed inside the enclosure and which surrounds the pyrotechnic neutralizing charge, and a mitigating agent which is disposed in the enclosure and which covers the decontaminating agent.

Abstract: The invention concerns a device (1) for neutralizing a chemical or biological weapon (2), characterized in that it comprises: a sealed enclosure (3) which delimits an internal volume (31) and is movable between a retracted position and an extended position; a pyrotechnic neutralizing charge (4) which is disposed inside the enclosure (3); a decontaminating agent (5) which is disposed inside the enclosure (3) and surrounds the pyrotechnic neutralizing charge (4); a mitigating agent (6) which is disposed in the enclosure (3) and covers the decontaminating agent (5).

Abstract: A containment device including a dry curtain, adapted to be deployed for the containment or re-containment of a discharge area, such as an opening, e.g. a door, in response to an explosion. The device includes a ballast bar in the lower portion of the curtain, the ballast bar including cylinders of high-density foam alternated with cylinders of compressible low-density foam.

Abstract: A containment device including a curtain that can be deployed from a first wound or folded position into a second unwound position, and a case for storing the curtain in the first position. The case is formed by a plurality of adjacent modules, the plurality of modules including active modules that are equipped with means for retaining and releasing the curtain and passive modules that are not equipped with means for retaining and releasing the curtain.

Abstract: A confinement mechanism that includes a dry curtain of dimensions greater than the dimensions of a discharge surface to be re-confined, formed by an opening in a building, such as, for example, a door, the curtain deploying in response to a high-pressure wave emitted by an explosion. Advantageously, the curtain is arranged in an envelope and is released from the envelope and deployed in response to the high-pressure wave emitted by the explosion.
