Description

Patent Descriptive Report "Mobile Mass Decontamination Unit"

The present invention relates to a mobile unit - mass decontamination unit.

It concerns the technical domain of mobile units used in the case of nuclear, radiological, biological or chemical accidents (NRBC) evacuating, sorting out and decontaminating the victims. These units are used by civilian or military personnel to limit the evolution of victim contamination over time.

Mobile Mass Disinfection Units (UMD) must be installed quickly in a caution zone near the place of disaster.

Upstream of the um, the victims are welcomed by the personnel who tell them and identify them. Victims are then ordered to depend on whether they are valid or invalid then controlled for IlUMD due to their disinfection. In a manner known per se, the UMD includes different zones crossed by at least one valid pass (possibly one for women and one for men) and one invalid pass. The UMD usually include:

- A first take-out zone where clothes are cut and personal effects provided in separate bags and identified.

Invalid victims are installed in apples.

- a wet body disinfection intermediate zone where victims are washed with a decontaminant solution. Invalid victims are housed carried by staff rinsing them with the help of a douchette.

- a final zone of drying, controlling and dressing, some personnel dry victims leaving the disinfecting rain, control the rate.

of it from contamination and, if this last is under the authorized limit, leurss provide clothes available to evacuate the zone.

The again contaminated victims are redirected to the rains for a new disinfection.

One knows the UMD presenting itself / themselves under the tent shape and whose structure is modular and flexible to quick installation. Such a structure is described for example in EP 1,493,886 (UTILIS). Once this structure is put in place, one covers it with a flexible awning dividing the different zones.

The median length for exposing this type of UMD is about 1h30 and requires four to five people minimum, which remains relatively long and expensive in the workforce. This installation length may be lengthened in case where weather conditions are for example unfavorable in case of wind and / or rain.

It is important that UMD does not reject contaminated sewage from the wet disinfection intermediate zone in the environment. Therefore, it is customary to have the surrounding wall a first reservoir for clean water and a second reservoir in which water contaminated exit from the disinfection intermediate zone is provided. The use of these two outside reservoirs requires relatively significant free space around the surrounding wall of I1UMD, which is not always possible according to the intervention site. The necessary place for installing the UMD is especially important as the whole material (heating, group electrogen, pumping element, ...) is arranged outside the surrounding wall. Another drawback lies in the fact that the material placed outside the surrounding wall is vulnerable to external natural aggressions (rainfall, temperatures, ...) which requires specific protective means.

Facing all the drawbacks of the prior art, the main technical problem that the invention solves to consider is to propose an UMD capable of being easily and quickly put in place with minimal staffing.
