DESCRIPTION:

BRIEF SUMMARY
FIELD OF THE INVENTION

The invention relates to an apparatus for individual decontamination, mainly for military use.


BACKGROUND OF THE INVENTION

The decontamination glove of the French army which is part of the individual soldier's equipment and whose active element is constituted by an absorbing powder of diatomic earth, fuller's earth, or other cleaning clay, has three main disadvantages:
The first is the fact that its use (done by patting with the glove on any contaminated clothing surface) inherently forms around the soldier a cloud of powder full of the toxic agent that it has absorbed and that can be carried away by wind or a simple breeze relatively long distances where it can contaminate clean locations.
The second is that is that its use for decontaminating a gas mask as well as the other equipment of the soldier, in particular his rifle, is not very reliable. In effect on the one hand access to certain contaminated surfaces is difficult if not impossible because of the shape of the glove (lack of suppleness because it is too thick) and on the other hand there is not only the possibility of scratching transparent surfaces (visor or eye-pieces) but also the risk of depositing the earth impregnated with the toxic agent in the screwthreads and other cavities where it can be held.
Finally, the third disadvantage, which is not the least, is that a powder, whatever it be made of, not only does not destroy the toxic agent that it absorbs but can also under certain circumstances release it which then presents a certain danger to the environment.
The term "decontamination" glove for this type of product is therefore an incorrect name in the sense that it designates a function that it does not completely fulfill.


OBJECT OF THE INVENTION

It is therefore an object of the present invention to provide an improved decontamination kit or apparatus particularly suitable for military use.
The present invention, which palliates these cited disadvantages, relates to a decontamination apparatus based on a different concept. This apparatus permits in effect:
in a first step, absorbing without polluting the major part of the toxic agent fixed on the clothing, the mask, and the equipment without subsequently releasing it,
in a second step, chemically destroying the unabsorbed toxic agent on the clothing, on the mask (without the risk of scratching its transparent parts), as well as on the equipment (without the risk of leaving a deposit inside spaces where it is possible to trap the toxic agent).
To this end the main object of the invention is an individual decontamination apparatus which includes inside a common package and/or case both an absorbent mitten-type glove and a separate wiping towel that can be impregnated with an active decontaminant made in situ when needed. Preferably the apparatus according to the present invention comprises in the same package and/or case a device serving for the preparation in situ of the active decontaminant provided for impregnating the wiping towel.
Preferably the individual decontamination apparatus is to start with isolated from the ambient atmosphere by a flexible protective package formed of a synthetic-resin film that is impermeable to toxic agents. The flexible package, provided with means facilitating opening it, preferably encloses a case of semirigid material and parallepipedal shape formed by two hollow case parts interconnected by a spring hinge; the case thus opens like a book but lengthwise and the spring hinge holds it open while in use. A fixed bar disposed along an edge opposite the spring hinge is usefully provided for maintaining the two case parts stuck together such that the case remains closed before use of the apparatus.
According to a preferred embodiment, the two case parts each have around their edges a seal strip intended to receive a peelable cover film ensuring perfect sealing with respect to the exterior of the internal spaces of the two case parts. The interior of one of the two case parts holds the absorbent glove and the device serving for the
