Description




TECHNICAL FIELD




The present invention is directed to a decontamination system and method, and more particularly to a system and method for decontamination and contaminant processing of personnel.




BACKGROUND OF THE INVENTION




Military, law enforcement, fire department, and other public safety personnel often encounter situations in the line of duty involving chemical, biological, or other potentially harmful contaminants. As an example, military personnel may be exposed to chemical or germ warfare. Public safety personnel may be exposed to toxic areas, toxic waste cleanup, or other toxic environments. The personnel can be exposed to potentially harmful chemicals, biological agents, and other contaminants, such that the person's body, clothing, and equipment may be contaminated.




Often when a situation occurs in which personnel are contaminated, the personnel need to be decontaminated as soon as possible to best protect their safety. The decontamination process should be conducted in the best manner possible without further contamination of other personnel and equipment. It is highly desirable to set up a portable decontamination area close to the site where the personnel were contaminated, so the contaminated personnel do not need to be transported to a remote decontamination facility. One difficulty experienced in the prior art is being able to quickly and easily transport sufficient decontamination equipment to a selected location to create the temporary decontamination area. A further difficulty experienced is the ability to quickly construct the temporary facilities with the necessary equipment so that the personnel can be decontaminated as quickly as possible. Temporary facilities and related necessary equipment have been very difficult to transport in an orderly manner. The temporary facilities and equipment also typically require very labor-intensive assembly, including extensive man hours and tools to assemble the components of the facilities or equipment.




Decontamination of the personnel should be conducted as quickly and thoroughly as possible for the personnel's safety. The conventional decontamination facilities and processes can be extremely cumbersome and difficult to manage, particularly when a large number of contaminated personnel and equipment must be processed. A further difficulty experienced in conventional systems and processes for decontamination of multiple personnel is that the contaminates on the personnel and equipment can become airborne and further contaminate the personnel within the decontamination area, including those personnel that have already been substantially decontaminated. Accordingly, it is highly desirable to allow personnel and equipment to be decontaminated while containing the contaminants so others are not contaminated or re-contaminated during the process.




SUMMARY OF THE INVENTION




Embodiments of the present invention provide a decontamination and processing system and methods that overcome drawbacks experienced by the prior art.

DETAILED DESCRIPTION




In the following description, certain specific details are set forth in order to provide a thorough understanding of various embodiments of the invention. However, one skilled in the art will understand that the invention may be practiced without these details. In other instances, well-known structures usable with the decontamination and containment process system or methods have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments of the present invention.

FIG. 1

is a schematic top plan view illustrating a decontamination and containment processing system


10


in accordance with one embodiment of the present invention. This system


10


is shown deployed on a selected decontamination area


12


, such as a field, parking lot, or the like. In one embodiment, the system


10


is deployed on a football field.




The decontamination and containment processing system


10


contains a plurality of collapsible components that can be easily packed for transportation to a selected decontamination area


12


where the system is deployed. As best seen in

FIG. 2

, the decontamination and containment processing system


10


of the illustrated embodiment includes a plurality of collapsible and packable components


20


, including shelter assemblies, weapon clearing and storing assemblies, signage assemblies, rack assemblies, hanger assemblies, hamper assemblies, washtub assemblies, a shower and water delivery systems, and other components discussed in greater detail below. The components


20


of the system


10


can be selected and combined in many configurations to allow a decontamination process to be developed and quickly implemented for any number of contamination scenarios. The selected components


20


can be packed into one or two transport containers


22


to be transported and deployed at the selected decontamination area


12


. The containers


22


of the illustrated embodiment are 4 ft×4 ft×8 ft containers. Accordingly, the decontamination and containment processing system


10


provides a fully operational transportable contamination control area that can be deployed easily and quickly for the effective and efficient decontamination of personnel and equipment.




The decontamination and containment system


10


is designed so it can be deployed and set up by hand without requiring any tools, thereby allowing for quick and easy deployment. When the system


10


is deployed, as shown in one configuration in

FIG. 1

, a series of sequential stations


14


are provided that allows for multiple contaminated personnel to be systematically decontaminated as they move through the multiple stations. The multiple stations


14


are arranged sequentially on the decontamination area


12


in a diagonal pattern. Each station is substantially facing into the wind so that any contaminants that may become airborne at a station do not blow back into a previous station and re-contaminate personnel or equipment at that previous station.




The deployed system


10


is capable of receiving multiple contaminated personnel, such as military personnel, public safety personnel, or the like, who have been contaminated with chemical or biologically active contaminants. The personnel are received at a first receiving station


16


, evaluated, and started through the decontamination process. The contaminated personnel are then move from the first, receiving station


16


and processed sequentially through a plurality of follow-on stations


18


, as discussed in greater detail below, to effectively remove all contaminated equipment and clothing, and to de-contaminate the personnel after being processed through the last station.





FIG. 3

is an isometric, partially cutaway view of a shelter assembly


30


of the decontamination and containment processing system


10


. The shelter assembly


30


includes a collapsible shelter frame


32


that supports a collapsible roof frame


34


. A flexible, waterproof roof cover


36


extends over the roof frame


34


and releasably attaches to the roof frame and to the shelter frame


32


. The roof cover


36


is securely retained on the roof frame


34


so it can withstand extreme conditions such as wind, rain, snow, dust, and the like. Flexible, full-length wall panels


38


are releasably attached to the shelter frame


32


and also to the roof cover


36


to provide fully enclosed shelter. The wall panels


38


are securely retained on the shelter frame


32


so they can also withstand wind, rain, snow, dust, or other extreme conditions that may be encountered.




In the illustrated embodiment, the wall panels


38


are elongated panels that include water-runoff flaps


40


along the lower perimeter of the shelter assembly


30


. The water-runoff flaps


40


extend outwardly over a portion of the ground next to the wall panels so water running down the sidewalls is directed away from the shelter structure. The water-runoff flaps


40


also provide an area of the wall panels


38


on which sand bags or other weighted securing devices can be placed to hold the wall panels down if the shelter frame cannot be adequately staked to the ground. The roof cover


36


and wall panels


38


of the illustrated embodiment are made of durable, waterproof, cloth-like material that can be easily and quickly removed from the shelter and roof frames


32


and


34


, and folded into a stored condition. While the shelter assembly


30


illustrated in

FIG. 3

has the wall panels


38


and roof cover


36


installed, the shelter assembly in an alternate embodiment can have just the wall panels or just the shelter desired.




Deployment of the shelter assembly


30


includes deploying the shelter frame


32


and roof frame


34


to form the internal framework before the wall panels


38


or roof cover


36


are installed.

FIG. 4

shows the shelter frame


32


in a collapsed position,

FIG. 5

shows the shelter frame in an intermediate, partially expanded position, and

FIG. 6

shows the shelter frame in the fully expanded position with the roof frame


34


. The shelter frame


32


of the illustrated embodiment has eight vertical support legs


42


, each connected to a pair of scissoring cross members


44


. In one embodiment, the support legs


42


and scissoring cross members


44


are lightweight, fiberglass tubes, each with a substantially square cross-sectional shape. As best seen in

FIGS. 4 and 5

, each pair of scissoring cross members


44


are pivotally interconnected at middle portions


45


of each cross member, so the cross members scissors with respect to each other as the shelter frame


32


is expanded.




Each of the scissoring cross members


44


are securely but pivotally connected at an upper end


46


to an upper end


48


of a respective support leg


42


. The bottom end


50


of each scissoring cross member is slidably connected to an adjacent one of the support legs


42


at an intermediate position below the upper end


48


spaced apart from the first support leg. When the shelter frame


32


is in the collapsed position (FIG.


4


), the support legs


42


are all nested immediately next to each other, and the bottom end


50


of each cross member


44


is spaced away from the upper end


48


of the of the respective support leg


42


. As the shelter frame


32


is moved from the collapsed position (

FIG. 4

) through the intermediate position (

FIG. 5

) toward the expanded position (FIG.


6


), each pair of cross members


44


scissors about their middle portions


45


, thereby sliding the bottom end


50


of each cross member


44


upwardly along the respective support leg


42


toward its upper end


48


.





FIG. 7

is an enlarged isometric view showing the upper end


48


of a support leg


42


that includes connecting bracketry


52


that pivotally connects to two of the cross members


44


. The bracketry


52


includes a pair of U-joints


54


that pivotally attach to the upper end


46


of each cross member


34


and also pivotally attached to a body portion


56


of the bracketry. The bracketry's body portion


56


is bolted or otherwise affixed to the support leg's upper end


48


. As the shelter frame


32


is moved toward the expanded position, each cross member's upper end


46


pivots at the respective U-joint


54


, and the U-joint also rotates relative to the bracket's body portion


56


. Accordingly, the bracketry


52


allows for the relatively complex movement of the support legs


42


and the respective scissoring cross members


34


. In the illustrated embodiment, the bracketry


52


is a metal component fastened to the fiberglass support legs and cross members. Other embodiments can use brackets made of other sufficiently durable material.





FIG. 8

is an enlarged isometric view showing the bottom ends


50


of the cross members


34


connected to a sliding bracket


60


that slides over the respective support leg


42


. The sliding bracket


60


of the illustrated embodiment includes body


61


formed by a metallic sleeve that extends around the support leg


42


, although other sufficiently durable materials can be used in other embodiments. The sliding bracket's body


61


is pivotally connected to two U-brackets


62


that are pivotally connected to the lower ends


50


of the respective cross members


44


. As the cross members


44


are scissoring when the shelter frame


32


is moving between the collapsed and expanded positions, the sliding bracket


60


slides axially over the respective support leg


42


. The U-brackets


62


pivot relative to the body


61


to accommodate the movement of the cross members


44


. Accordingly, the shelter frame


32


easily and smoothly moves between the collapsed and expanded positions.





FIG. 9

shows an enlarged isometric view showing the sliding bracket


60


and a quick-disconnect spring pin


64


mounted in one of the support legs


42


. The spring pin


64


releasably retains the sliding bracket


60


in a raised position on support leg


42


when the shelter frame


32


is in the extended position. The spring pin


64


extends through an aperture


68


formed in the support leg


42


and is biased outwardly with a spring member (not shown) contained within the support leg. Sliding bracket


60


has an engagement ramp


69


formed in the top portion of the body


61


, so the sliding bracket presses the spring pin


64


inwardly into the aperture


66


as the sliding bracket slides upwardly along the support leg


42


and over the spring pin. Once the sliding bracket


60


moves past the spring pin


64


, the spring pin returns to its locking position and blocks the sliding bracket


60


from moving downwardly past the spring pin. When the spring pin


64


is manually depressed into the aperture


68


, the sliding bracket


60


can move downwardly along the support leg


42


, past the spring pin, thereby allowing the shelter frame


32


to move from the expanded position to the collapsed position.




In operation, the shelter frame


32


is stored in the collapsed position, shown in

FIG. 4

, so all of the support legs


42


are nested together and the slide brackets


60


are in a lowered position on the respective support legs


42


. When the shelter frame


32


is expanded, the support legs


42


move away from each other, thereby causing the cross members


44


to scissors, so the slide brackets


60


move axially along the respective support legs until the slide brackets move over and past the spring pins


64


. The spring pins


64


snap into the locked position, thereby retaining the cross members and the support legs


42


in the fully expanded position. To collapse the shelter frame


32


, a user simply presses the spring pins


64


into the apertures


68


and moves the sliding brackets


60


axially along the support legs. Accordingly, the cross members


44


scissors relative to each other, thereby pulling the support legs


42


toward each other to the collapsed position. Therefore, the shelter frame


32


can be expanded and collapsed easily and quickly without requiring the use of any tools.





FIG. 10

shows an enlarged front perspective view of the shelter frame


32


supporting the roof frame


34


that is covered by a roof cover


36


.

FIG. 11

shows the roof frame


34


in a collapsed positioned with upper end of frame legs


76


pivotally connected to an apex disk


78


. The frame legs


76


expand outwardly from a collapsed position illustrated in

FIG. 11

to an expanded position, shown in the

FIG. 10

, so the roof frame


34


generally has a pyramid shape.

FIG. 12

shows free ends


80


of the roof frame's legs


76


that attach to the upper ends


48


of the shelter frame's support legs


42


. The upper ends


48


of the support legs


42


have apertures


82


therein that removably receive the free ends


80


of the roof frame's legs


76


. Accordingly, the roof frame


34


is removably attached to the top of the shelter frame


32


by plugging the roof frame's legs


76


into the top of the support legs


42


without requiring any tools for assembly. In the illustrated embodiment, the frame legs


76


of the roof frame


34


are made of the same fiberglass tubes that form the shelter frame


32


.




As best seen in

FIG. 13

, a vent cap


88


is threadably attached to the apex disk


78


on the top of the roof frame


34


. The vent cap


88


is cylindrical with a closed top end and apertures


90


in the sides that allow air to flow through the vent cap and into or out of the shelter assembly


30


, while keeping rain, snow, dust and the like out. The vent cap


88


, thus, provides an “all weather” element protection while venting the shelter assembly


30


.




As best seen in

FIGS. 10 and 14

the roof cover


36


is a removable cover that extends over and fully encloses the roof frame


34


. The roof cover


36


in the illustrated embodiment is a waterproof and windproof cloth-like material that can be easily folded into a compact bundle for easy storage. A plurality of straps


94


(

FIG. 14

) attached to lower edges of the roof cover


36


are removably attached to the cross members


44


to securely retain the roof cover on the roof frame


34


. The straps


94


also work to securely hold the roof frame


34


on the shelter frame


32


. The straps


94


can include buckles, quick clips, hook-and-loop fasteners, or other attachment configurations to allow the straps to securely retain roof cover


36


to the shelter frame


32


and over the roof frame


34


.





FIG. 15

is a front perspective view of the shelter assembly


30


with the wall panels


38


removably attached to the shelter frame


32


and the roof cover


36


on the roof frame


34


to form a fully enclosed shelter. The wall panels


38


are made of a flexible, waterproof and windproof cloth-like material, so the panels can be easily folded into a compact bundle for easy storage. The wall panels


38


can have cutouts


98


with flaps


99


that can be moved between open and closed positions to form doors or windows in the shelter assembly


30


. The wall panels


38


of the illustrated embodiment extend along the entire height of the shelter frame


32


from the roof cover


36


to the run-off flaps


40


.




As best seen in

FIG. 16

, the top edges


102


of wall panels


38


are adjacent to the roof cover


36


. A plurality of connector straps


104


each with a hook


106


thereon are connected to the top edges


102


. The hooks


106


removably attach to loops


108


on the roof cover


36


. Accordingly, the wall panels


38


can be easily and quickly hooked onto the roof cover


36


. The top edges


102


of the wall panels


38


also have a fastener strip


110


of hook or loop material, and the lower edges


111


of the roof cover


36


(shown in

FIG. 16

lifted away from the wall panel's top edges for illustrative purposes) have the mating fastener strip


112


of loop or hook material. The fastener strips


110


and


112


releasably attach to each other to form a substantially weather tight seal between the wall panels


38


and the roof cover


36


and to help hold the wall panels adjacent to the shelter frame. The hooks


106


, straps


108


and the fastener strips


110


and


112


allow the wall panels to be easily and quickly installed on the shelter assembly


30


during the set up of the decontamination system


10


(

FIG. 1

) without requiring special tools for the setting up the system. The shelter assembly


30


can also be disassembled quickly and easily without requiring tools. While the illustrated embodiment uses hooks


106


, straps


108


, and hook-and-loop fastening strips, other connection devices can be used in alternative embodiments, such as snaps, zippers, quarter-turn fasteners or the like.




The shelter assembly


30


is one of the major components of the decontamination and contaminant system


10


, and as shown in

FIG. 1

, is one of the central components of the system's first station


16


. Other components


20


of the system making up the various stations are discussed in greater detail below in connection with the respective station in which the components are used. The decontamination and containment system


10


can be set up with multiple stations for the decontamination process. As best seen in FIG.


1


, the first station


16


is positioned adjacent to an entrance


122


to the decontamination area


12


. The first station


16


of the illustrated embodiment of

FIG. 1

includes an initial decontamination area


124


, a weapons clearing area


125


, a wash and hold area


126


, and an external equipment removal area


128


. It is noted that the stations of the decontamination system


10


and components in those stations can be set up to provide a variety of station configurations to accomplish the particular decontamination process required for a given situation. Thus, the decontamination system


10


illustrated in

FIG. 1

is an illustrative example showing one embodiment of station configurations that can be used for a selected decontamination process.




As best seen in

FIG. 17

, the initial decontamination area


124


of the illustrated embodiment includes a signage assembly


132


mounted on a station frame


130


, a dual hamper assembly


134


connected to the station frame, and a collapsible trash hamper


136


adjacent to the station frame. The station frame


130


is a collapsible, lightweight frame having a configuration very similar to the shelter frame


32


discussed above and illustrated in

FIGS. 6 and 10

. The station frame


130


, however, is smaller and only has four support legs


42


interconnected with the scissoring cross members. The station frame


130


is also constructed with the fiberglass tubes that are used to construct the shelter assembly. As the station frame


130


is moved between the expanded and collapsed positions, the sliding bracket


60


moves axially along the respective support leg


22


as the upper bracketry


52


allows the cross members


44


to pivot relative to the support legs


42


. The sliding bracket


60


is releasably retained by the spring pins


64


when the station frame


130


is in the expanded position as shown in FIG.


17


. The support legs


42


and station frame


130


can be anchored to the ground with stakes (not shown), sandbags


138


(as illustrated), weights, or the like.




The signage assembly


132


mounted on the station frame


130


has a sign box


140


supported on a pair of cross bars


142


that rest on top of opposing cross members


44


. The sign box


140


contains a pull-down sign support


144


that provides flat surfaces on opposing sides to which a selected sign, map, informational placard, or other visual display


146


can also be removably attached. The selected visual display


146


is positioned to provide information to personnel entering the initial decontamination area


124


. The lower corners of the sign support


144


are connected to tether lines


148


that can be anchored to the ground to hold the sign support in a downward extended position. The tether lines


148


also help prevent the sign support


140


from flapping in the wind when the sign support is pulled down into the extended position.




The sign support


144


is connected to a spring reel


143


contained in the sign box


140


. The spring reel


143


is angularly biased to automatically roll the sign support


144


into the sign box


140


when the tether lines


148


are released. Thus, the sign support


144


is stored in the sign box


140


when not in use. The sign box


140


is sized to removably contain a variety of selected signs, maps, instructional placards or other visual display that can be removably attached to the sign support


144


. Accordingly, the visual information provided to the personnel can be easily and quickly changed by replacing one visual display


146


with another one from the sign box


140


. The visual displays


146


can be retained on the sign support with clips, magnets, adhesive strips, hook-and-loop fasteners, or other suitable connection mechanisms. In an alternate embodiment, the sign support


144


can also have a reflective coating on it so the sign support can be used as a projection screen. Thus, information can be actively displayed on the signage assembly


132


via a projection system or other multimedia system.




The signage assembly


132


is positioned above the dual hamper assembly


134


with the station frame


130


.

FIG. 18

illustrates the dual hamper


134


in an expanded position and removed from the station frame


130


. The dual hamper


134


is a soft, flexible collapsible hamper configuration with two hamper receptacles


150


removably attached to each other by connector clips


152


. The hamper receptacles


150


each also have connection straps


154


connected to the two outer corners


130


.




As best seen in

FIG. 17

, the connections straps


154


releasably attach to the support legs


42


of the station frame


130


to hold the hamper receptacles in an upward, expanded position. The hamper receptacles


150


are sized to allow selected items, particularly contaminated items, to be deposited into them so as to contain the contaminates on those items in a controlled area. The lower corners


156


of the hamper receptacles


150


have connection loops


159


that can be used to stake or otherwise hold the hamper receptacles on the ground. The hamper receptacles


150


can be easily and quickly installed onto the station frame


130


in the expanded position ready to receive the selected items from the personnel. When the hamper receptacles


150


are full or need to be replaced, the selected hamper receptacle can be easily removed from the shelter frame, separated from the other receptacle and replaced.





FIG. 17

also illustrates the collapsible trash hamper


136


that includes a collapsible, scissoring hamper frame


158


that supports a flexible, collapsible hamper bag


160


. The hamper frame


158


is movable between an expanded position and a flat, collapsed position (not shown). The hamper frame


158


holds the hamper bag


160


in an open position so as to receive trash or other discarded items. In the illustrated embodiment, the hamper bag


160


is a soft, flexible treated cloth bag, although other materials, such as plastic, can be used. Accordingly, the hamper bag


160


can be collapsed and stored in a very compact manner. When the hamper bag


160


is full, it can be removed from the hamper frame


158


and replaced with a new hamper bag.





FIG. 19

is a front perspective view showing the weapons clearing area


125


and the wash and hold area


126


of the first station


160


. The weapons clearing area


126


includes a weapons clearing and storing assembly


166


having a collapsible stand


172


that supports a weapons storage locker


174


and a weapons clearing box


176


. As best seen in

FIGS. 19 and 20

, the stand


172


includes a collapsible base


178


that is movable between a stored position (

FIG. 20

) and an expanded position (FIG.


19


). The base


178


of the illustrated embodiment includes four vertical legs


180


interconnected by scissoring cross members


182


. The scissoring cross members


182


are pivotally and slidably attached to the vertical legs so as to move in a scissoring action when the base


178


is moved between the collapsed and expanded positions. The cross members


182


are slidably connected to the vertical legs


180


and operate in the same manner as the shelter frame


32


and the station frame


130


discussed above. Thus, the collapsible base


178


can be moved into the expanded position and locked into place with the spring pins as discussed above without requiring tools for assembly. The base


178


, similarly, can be quickly and easily collapsed and stored without requiring tools for the disassembly.




When the stand


172


is in the expanded position, the top of the vertical legs


180


support a flat tabletop


184


removably attached to the base


178


. In the illustrated embodiment, the top of the vertical legs


180


each have a small projection member


185


extending upwardly when the base


178


is expanded. As best seen in

FIG. 21

, the tabletop


184


is made of two spaced apart plate members


186


with separate blocks


188


sandwiched therebetween. Apertures


189


are formed in the corners of the lower plate member


188


. When the table top


184


is placed onto the base


178


, the projections


185


extend into the apertures


189


in the tabletop's lower plate member


188


. The projection members


185


prevent the tabletop


184


from sliding off of the top of the base


178


. The tabletop


184


with the apertures


189


therein allows for very quick and easy assembly of the stand


172


without requiring any tools.




As best seen in

FIGS. 19 and 22

, the weapons clearing box


176


is mounted to the front side of the collapsible stand


172


below the tabletop


184


. In the illustrated embodiment, the rear side of the weapons clearing box


176


has a pair of hooks (not shown) that removably hook onto a stand's front set of cross members


182


. Accordingly, the weapons clearing box


176


can be quickly and easily attached to or removed from the stand


172


.




Referring now to

FIG. 22

, the weapons clearing box


176


has an outer metal container


192


that removably contains a rigid ballistic plate


191


and one or more ballistic absorption packs


194


. A lid


193


is pivotally attached to the outer container


192


to allow for easy access to the outer container's interior area and the ballistic absorption packs


194


. In one embodiment, the outer metal container


192


is made of


16


gauge stainless steel. While one of the ballistic absorption packs


194


is shown in

FIG. 22

removed from the outer container


192


for purposes of illustration, the ballistic absorption packs are fully contained within the outer container's interior area when the weapons clearing box is in use. The ballistic plate


191


includes an inner plate covered with composite fiber material to provide a structure that can substantially decelerate or stop a bullet. The ballistic absorption packs


194


are constructed with multiple layers of bulletproof material so the pack will stop a bullet discharged into it. In one embodiment, the ballistic absorption packs include soft armor, such as UDX1000 Composite Armor manufactured by Survival Inc., of Seattle, Wash.




The outer container


192


has a cylindrical firing tube


196


that communicates with the container's interior area and is aligned with the ballistic absorption packs


194


. The firing tube


196


is shaped and sized to receive the barrel of a weapon, such as a side arm, so the barrel points at the ballistic plate


191


and the ballistic absorption pack


194


. In operation, each personnel, such as a soldier or the like entering the first station


16


with a weapon moves to the weapons clearing assembly


166


, and aims the barrel of the weapon into the firing tube


196


toward the ballistic absorption packs


194


. The user then confirms that the weapon's chamber is clear of ammunition by attempting to fire the weapon. Most often, the weapon will be clear and nothing will occur in the weapon clearing box


176


.




In the event the weapon is fired and discharges a round that was not properly cleared, the bullet will strike the ballistic plate


191


and, if the bullet penetrates the plate, the bullet enters the ballistic absorption packs


194


until it is stopped while fully contained within the weapons clearing box


176


. Once a round is fired into the ballistic plate


191


and the ballistic absorption packs


194


, the plate and packs must be removed and replaced with a new ballistic plate


191


and ballistic absorption pack


194


. A lid


193


is pivotally attached to the outer container


192


to allow for easy access to the outer container's interior area and the ballistic absorption packs


194


.




After the personnel insure that the weapon is clear, the weapon is stored in the weapons storage locker


174


. The weapons storage locker


174


removably sits on top of the stands tabletop


184


. As best seen in

FIG. 23

, the weapons storage locker


174


has an outer case


186


that removably retains a plurality of storage plates


188


in the case's interior area. The storage plates


188


are vertically oriented and slide into and out of the outer case


186


along internal tracks (not shown). The storage plates


188


each have a plurality a retention members


190


removably mounted on opposing sides of the respective storage plate. The retention straps


190


of the illustrated embodiment are holsters and clip holders shaped and sized to removably retain sidearms, ammunition clips, and other selected weapon components. Thus, the weapons are safely stored on the storage plates


188


and fully contained within the outer case


186


. The outer case


186


includes a door


197


that can be closed and locked to securely enclose the weapons in the storage locker


174


.




The weapon clearing assembly


166


of the illustrated embodiment has a liquid/powder dispenser assembly


200


removably attached to the collapsible base


178


adjacent to the weapons clearing box


176


. The liquid/powder dispenser assembly


200


is provided to allow personnel to dispense a selected neutralizing liquid or powder on his or her hands or on a weapon before placing the weapon into the weapon storage locker


174


. The liquid/powder dispenser assembly


200


is discussed in greater detail below.




The wash and holding area


126


includes a pair of wash tub assemblies


168


and a shuffle box assembly


170


adjacent to the wash tub assemblies. A pair of the shelter assemblies


30


are positioned generally downstream of the wash tub assemblies


168


and shuffle box assembly


170


. In the illustrated embodiment, one shelter assembly


30


includes shelter frame


32


, roof frame


34


, and the roof cover


36


, but does not include the wall panels


38


discussed above. The second adjacent shelter assembly


30


includes the roof cover


36


and wall panels


38


to provide a fully enclosed shelter in which contaminated personnel are initially treated with a dusting agent and/or a decontamination/neutralizing agent. The dusting agent can be “Fullers Earth,” which is a highly refined clay, and the decontamination/neutralizing agent can be a chlorine spray. The dry dusting agent can help identify any “wet” contaminated areas and to stabilize the wet areas or droplets. The decontamination/neutralizing spray is adapted to help reduce the risk of potential harm to the contaminated personnel and any attendants or other processing personnel. The initial treatment in one embodiment utilizes a large, full-body, lightweight plastic tube bag sealed on one end and lined with a lightweight fabric impregnated with a decontamination/neutralizing agent. The bag is shaped in size to allow the personnel to step into the bag and an attendant pulls the bag up and over the individual. The attendant then rubs the bag over the outside of the contaminated personnel to both decontaminate and neutralize the personnel as well as contain any contaminates from the personnel within the bag. The bag, thus, provides a waterless shower-type application of the decontamination and neutralizing agent. The bag is then opened and lowered around the personnel so the personnel can step out of the bag. The bag is then sealed by the attendant and held for proper HAZMAT disposal. Accordingly, the bag provides an environmentally sound initial treatment while containing potentially hazardous contaminates within the bag so they can be disposed of in a proper manner without contaminating other personnel or attendants. In addition to providing an area for this initial treatment, the shelter assemblies


30


also provide an area where the personnel can rest and wait during the decontamination process before proceeding to the subsequent stations. The shelter assemblies


30


also provide an area where people running the decontamination process can set up administration materials if needed.




The wash tub assemblies


160


are positioned to allow the personnel entering the wash and hold area to wash their hands and arms. As best seen in

FIG. 24

, the wash tub assemblies


168


has a collapsible stand


202


and movable between a collapsed, substantially flat position (not shown) and an expanded position. A support strap


206


extends between the top portions of the stand, and a wash tub


208


is removably supported by the support strap and the top of the stand. The support strap


206


helps support the wash tub


208


on the stand


202


, particularly when the wash tub is filled with water or other selected decontamination/neutralizing solution, such as chlorine or bleach. In one embodiment, the shelter assembly


30


can also be converted into a decontamination tent that includes a plurality of ultraviolet lights. In this embodiment, a bladder is added within the tent and a misting station is also set up to direct a decontaminating mist, such as a formaldehyde fogger or other similar agent, onto the contaminated personnel. The misting station is effective for decontaminating or neutralizing chemical agents. The ultraviolet lights are provided, and when turned on, effectively “cook” biological agents that may have contaminated the personnel. After the personnel has been subjected to the ultraviolet lights or the misting station, the personnel exists the shelter assembly


30


and proceeds with the remaining portion of the decontamination process.




The shuffle box assembly


170


shown in

FIG. 16

is adapted to contain a selected dusting agent or decontamination/neutralizing agent and is positioned adjacent to the wash tub assemblies


168


, so personnel can step into the shuffle box and the neutralizing agent while using the wash tub assemblies. The personnel shuffles their feet within the shuffle box assembly


170


to get the neutralizing agent onto the personnel's boots, shoes, or other footwear. As best seen in

FIG. 25

, the shuffle box assembly


170


contains a durable inner bladder


250


removably supported by a shallow, collapsible frame


252


that forms a shallow, open box. In the illustrated embodiment, the inner bladder


250


is made of a durable plastic material that will not rupture or tear when personnel walk or shuffle through the shuffle box. The inner bladder


250


is also disposable so that the bladder can be used during a decontamination process, be appropriately disposed of, and replaced with the new clean bladder for another decontamination process and can be installed on the collapsible frame


250


.




As best seen in

FIGS. 25-28

, the shuffle box assembly


170


can be unpacked and assembled from a compact stored position (

FIG. 26

) to partially assembled positions (

FIGS. 27 and 28

) to the fully assembled position (

FIG. 25

) without requiring the tools for assembly. The collapsible frame


252


of the illustrated embodiment includes four stiff sidewall inserts


254


that are removably retained in pockets


255


formed in the perimeter of a flexible, fabric base


256


. When the shuffle box assembly


170


is in the stored position (FIG.


26


), the base


256


is rolled around the sidewall insets


254


so as to form a compact elongated unit easily transportable and requires a relatively small amount of storage space.




Assembly of the collapsible frame


252


is accomplished by unrolling the base


256


, removing the sidewall inserts


254


, and inserting the sidewall inserts into the pockets


255


(FIG.


28


). When all four of the sidewall inserts


254


are positioned into the respective pockets


255


, the four sidewalls


260


of the base


256


are retained in a vertical position to form the shallow open box. The sidewall inserts


254


are each retained within their respective pockets


255


by a retention strap


262


that can be easily fastened to close the pocket openings.




In the illustrated embodiment, the ends of the sidewall inserts


254


and pockets


255


are positioned at the corners of the frame


252


, so that if someone steps on one of the vertical sidewalls


260


, the sidewall can be flattened onto the ground without being damaged and without damaging the frame's other sidewalls. If one of the sidewalls


260


is flattened, it automatically returns to the vertical upright position because of the interconnection with the other sidewalls that were not flattened. Accordingly, the collapsible frame


252


is very durable and easy to use, as well as being easy to assemble and disassemble.




As illustrated in

FIG. 1

, the first station


120


also includes the external equipment removal area


128


positioned diagonally downstream of the wash and hold area


126


. The personnel move from the wash and hold area


126


to the external equipment removal area


128


and begin to systematically remove equipment or gear that they may be carrying or wearing before they progress to the other decontamination stations. In one embodiment, the equipment and gear is systematically removed from the ground up. As best seen in

FIG. 29

, the equipment removal area


128


includes a plurality of doffing racks


266


adapted to removably retain equipment thereon. The doffing racks


266


include a collapsible station frame


268


having the same configuration as the station frame


130


discussed above. The station frame


268


is movable between a collapsed position shown in

FIG. 30

to an expanded position shown in FIG.


31


. When the station frame


268


is in the expanded position, a collapsible hanger assembly


270


hooks onto the station frame's scissoring cross members


44


.




As best seen in

FIG. 31

, the hanger assembly


270


has a pair of elongated cross members


274


that hook onto the lower sections


272


of the scissoring cross members


44


with a pair of hooks


276


. The hooks


276


are pivotally connected to the end portions of the cross members


274


and are oriented in opposing directions. This opposing orientation places the hooks


276


in proper position to engage spaced-apart lower sections


272


of the scissoring cross member


44


, so the respective cross member is not skewed. The hooks


276


also allow the cross members


274


to be easily and quickly attached to the station frame


268


. A plurality of hanger bars


277


are slidably attached to the bottom of the cross members


274


.




As best seen in

FIG. 32

, each cross member


274


has an elongated slot


278


formed in its bottom side


279


, and a retention nut


280


is slidably captured within the slot. The retention nut


280


removably retains a connector


282


connected to the end of the respective hanger bar


277


. In the illustrated embodiment, the connectors


282


are threaded bolts that screw into the respective retention nuts


280


. The connectors


282


can be loosely attached to the retention nuts


280


so that the retention nuts can slide within slots to selectively move the hanger bars


277


along the cross member


274


. The connectors


282


can also be tightened down against the respective retention nuts


280


so the hanger bars


277


are securely attached to the cross members


274


and temporarily not movable.




In the illustrated embodiment, the hanger bars


277


and the cross members


274


are lightweight, strong, fiberglass bars that can support relatively heavy external equipment. The hanger bars


277


removably receive a plurality of doffing hooks


284


adapted to hold the external equipment above the ground. The doffing hooks can also slide along the hanger bars


276


to allow the hanging equipment to be easily moved or adjusted as needed.




As best seen in

FIG. 31

the station frame


268


also has a pair of thin stabilizing cables


301


, each extending between two of the support legs


42


, and connected to the upper bracketry


52


on the support legs. The stabilizing cable


301


is fairly taut when the station frame


268


is in the expanded position, and the cable helps prevent the station frame from being over expanded. The stabilizing cable


301


also provides a “clothes-line” type structure on which lightweight items can be hung.




As best seen in

FIG. 1

, the equipment removal area


128


of the illustrated embodiment also includes a pair of wash tub assemblies


168


(discussed above) positioned so personnel can wash after hanging the equipment on the doffing hooks


284


. The equipment removal area


128


is provided with one or more trash hamper assemblies


136


(discussed above) to receive and contain any trash, debris, or the like before the personnel progresses to the second station


290


of the decontamination and containment system


10


.




The second station


290


of the illustrated embodiment includes a boot wash area


292


and a mask wipe and hood removal area


294


. The boot wash station


292


includes a pair of shuffle box assemblies


170


positioned upstream from the mask wipe and hood removal area


294


. Accordingly, personnel moving the into the second station


290


walk through one or more of the shuffle box assemblies


170


before progressing to the mask wipe and hood removal area


294


. As best seen in

FIG. 33

, the mask wipe and hood removal area


294


includes a plurality of wash tub assemblies


168


adjacent to a station frame


130


that removably retains a dual hamper assembly


134


(discussed above) and positioned to receive hoods, hats, masks or other head gear removed from the personnel. In one embodiment, the mask wipe and hood removal area


294


includes a signage assembly


132


(as discussed above and shown in

FIG. 17

) to provide instructions and/or information about the mask wash and hard removal process.




The mask wipe and hood removal area


294


includes tri-wipe dispenser assemblies


296


releasably attached to the station frame


130


. The tri-wipe dispenser assemblies


296


allow the personnel to easily and cleanly obtain selected towelettes to clean or neutralize the mask that the personnel may be wearing during the decontamination process. The towelettes could also be used to clean or wipe the personnel's head, neck, face, or the like.




As best seen in

FIG. 34

, each tri-wipe dispenser assembly


296


of the illustrated embodiment has an elongated, flexible base


298


with attachment straps


300


securely attached to the corners of the base. The attachment straps


300


securely retain the base


298


so it is substantially vertically oriented. The attachment straps


300


each include an adjustable quick clip


302


that allows the respective attachment strap to wrap around the respective support leg


42


of the station frame


130


and clip to itself. In the illustrated body, the upper attachment straps


300


extend around the support legs


42


at a position above a portion of the scissoring cross member


44


, so the cross member prevents the dispenser assembly


296


from sliding or migrating down the support leg


42


. The lower attachment straps


300


are each wrapped around a middle portion of the respective support leg


42


and tightened enough to stabilize the bottom of the base


298


and inhibit excess movement of the base, while not excessively pulling on the support leg.




Three towelette dispensers


304


are attached to the base


298


so the dispensers are sequentially aligned horizontally. The towelette dispensers


304


each have a container portion


306


that removably retains a plurality of towelettes


308


therein. A cover flap


309


is attached to each container portion


306


and positioned to cover an open top side of the is container portion. In the illustrated embodiment, the cover flaps


309


are securely retained in a closed position by a pair of quick clips


311


attached to the container portion


306


. Other embodiments can provide other cover configurations and retention devices for the towelette dispensers to prevent rain, debris, or other contaminants from getting into the container portion


306


and onto the towelettes


308


.




Each towelette dispenser


304


is attached to a support strap


312


that extends up and over the scissoring cross member


44


, connects to the back side of the base


298


, and then connects to itself via a quick clip


313


. The support strap


312


is adjustable at the quick clip


313


so as to provide vertical support to the container portion


306


, particularly when a towelette


308


is removed. The adjustable support straps


312


also allow the positions or orientation of the container portions


306


to be manipulated if needed when the tri-wipe dispenser


296


is being set up on the station frame


130


. In the illustrated embodiment, an anchoring strap


314


is attached to the back side of the base


298


and also removably attaches to the middle of the scissoring cross members


44


. The anchoring strap


314


prevents the base


298


and the towelette dispensers


304


from sliding laterally on the station frame


130


during use. While the illustrated embodiment shows the use of straps and quick clips, other support devices and attachment mechanisms can be used in alternate embodiments to hold the base


298


and towelette dispensers


304


in a stable position on the station frame


130


.




As best seen in

FIG. 35

, the towelette dispensers


304


contain a plurality of the towelettes


308


(shown in hidden lines in a roll form), so the towelettes can be dispensed one at a time through a slot


314


formed in the bottom side


316


of the container portion


306


. In one embodiment, the towelettes


308


are releasably connected to each other in series so one towelette can be removed through the slot


314
