CROSS REFERENCE 
   The present application is related to provisional patent application Ser. No. 60/344,281 filed Dec. 27, 2001. 

   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention is directed to a decontamination tub and more specifically to a decontamination tub for bodies, parts of bodies, blood, body fluids and decontamination medium. 
   2. Description of Related Art 
   In the event of an accident, or catastrophe (military or civilian) where persons are killed, there is a need for the bodies and/or body parts to be collected and removed from the scene. This is most commonly done by the rescue personnel placing the body and/or body parts in “body bag”. However, the “body bag” does not effectively contain blood and body fluids and does not provide means to decontaminate the body or body parts when such treatment is required. Decontamination may be needed in the event of exposure to biological and/or chemical agents. 
   Furthermore, it is sometimes necessary for police, forensic or medical purposes, to store the body, body parts and/or body fluid for subsequent examination. The presently available systems do not provide a convenient means which is rigid and protects the body or body parts and retaining body fluids and decontamination medium. 
   BRIEF SUMMARY OF THE INVENTION 
   It is an object of the invention to provide a rigid tub for retention of bodies, body parts and body fluids following a military action, an accident or catastrophic event. 
   It is a further object of the invention to provide a means to decontaminate bodies and/or body parts. 
   In accordance with the teachings of the present invention, there is disclosed a tub for receiving a body and/or body parts. Drainage means is provided on the tub for facilitating collection of blood and/or body fluids. A valve means is provided on the tub, so that once the body part or parts are received in the tub, a decontamination medium may be introduced into the tub to decontaminate the body and/or body parts in the tub. The blood and/or body fluids and the decontamination medium may be drained through the valve means. 
   In further accordance with the teachings of the present invention, there is disclosed a stack of decontamination tubs nested vertically with respect to each other. Each of the decontamination tubs comprises a rigid tub for collection of blood and/or body fluids. A decontamination medium may be introduced into the tub to decontaminate the body and/or body parts in the tub. Each of the tubs has a bottom portion provided with ridges, thereby facilitating movement of the tub along a roller system. Each of the tubs further has four notches, two at each opposite end of the tub, respectively. A stretcher is received in the notches, depending within each tub and having the body and/or body parts resting thereon. A valve means is formed on each tub such that the blood, body fluids and the decontamination medium may be drained through the valve means. 
   In still further accordance with the teachings of the present invention, there is provided a method of decontaminating bodies and/or body parts following exposure to hazardous materials. A tub having four walls and a bottom is provided. A drain valve is connected to the corner of the tub. The body and/or body parts are placed on a carrying means. The body fluids are collected in the tub. A decontamination medium is connected to a spraying device. The decontamination medium is sprayed onto the body and/or body parts to decontaminate the body and/or body parts. The decontamination medium collects in the tub. The valve in the corner of the tub is opened and the body fluids and decontamination medium drain into a reservoir. 
   These and other objects of the present invention will become apparent from a reading of the following specification taken in conjunction with the enclosed drawings.

   DESCRIPTION OF THE PREFERRED EMBODIMENT 
   Referring to  FIGS. 1–8 , a tub  10  is formed from a rigid plastic material such as high density polyethylene. Preferably, the tub  10  is approximately 80 inches long, 30 inches wide and 10 inches deep. An outwardly overhanging lip  12  is formed circumferentially around the tub  10 . Spaced apart around the lip  12  are a plurality of grip areas  14  which provide a means for persons to grasp the tub  10  for ease of carrying. Preferably one grip area  14  is formed in at opposite ends of the tub  10  and three grip areas  14  are formed along each side of the tub  10 . Approximately three ribs  16  are formed longitudinally on the bottom of the tub  10 . Not only do the ribs provide structural strength to the tub  10 , but the ribs extend outwardly from the bottom of the tub and serve as a rail for moving the tub on a roller type conveyor as will be explained. In addition, the ribs  16  facilitate drainage of liquids within the tub  10 . In each end wall of the tub, there are formed two spaced-apart notches  18 . The use of these notches will be discussed. 
   In one corner  20  of the tub  10 , a ledge  22  is formed angularly with respect to the pair of adjoining walls of the tub. Preferably, the angle is 45°. In a molded tub  10 , the formation of the internal ledge generates a corresponding external depression in the outer wall of the tub  10 . It is also preferred that a ridge  26  be formed on the upper surface of the ledge  28  above the vertical face of the ledge  22 . Thus, a space is provided for placement of loose articles which may be associated with the body or body parts. 
   An opening  24  is formed in the vertical face of the ledge  22  adjacent to the bottom of the tub  10 . A drain valve  28  is connected to the opening with a control means outside of the tub  10 . In this manner, liquid collected within the tub  10  may be drained from the tub  10 . 
   A flexible cover  30  having an elastic band circumferentially thereof is fitted over the open top of the tub as shown in  FIGS. 9 and 10 . The flexible cover preferably is formed from polyethylene and is water resistant, mildew resistant and treated with an anti-fungal material. The flexible cover fits snugly over the tub  10  and its contents. A transparent pocket  32  is formed on the outside of the cover so that identification or other information may be provided. 
   As shown in  FIG. 11 , a transfer sheet  34  is provided and is placed in the tub  10 . The transfer sheet  34  is approximately 78 inches long and 24 inches wide and, preferably, is formed of monofilament polypropylene in a basket-type weave. This permits passage of liquid through the transfer sheet  34  and allows complete submersion of a body and/or body parts in the tub  10 . Also, the transfer sheet  34  retains items which provides easy collection of trace evidence. A plurality of straps  36  are connected to the transfer sheet  34  to provide a means of holding the transfer sheet  34  containing the body and/or body parts and to dispose the transfer sheet  34  in the tub  10 . 
   A stretcher  38  having four outwardly extending handles is placed on the tub  10  with one handle being received in a respective one of the notches  18  formed on the opposite ends of the tub  10  as shown in  FIG. 12 . The type of stretcher  38  is not critical, the important factor being that the stretcher, including the handles, is longer than the tub  10  and the handles are spaced apart by a distance equal to the spacing between the notches  18  on the tub  10 . It is also advantageous if the bed of the stretcher  38  is made from a mesh material which can withstand decontamination procedures. The Raven® Model 90C Litter sold by North American Rescue Products, Inc., Easely, S.C. has been found to meet the requirements. 
   As shown in  FIG. 13 , a plurality of tubs  10  may be stacked or nested vertically for ease of transport and storage. The opposite ends of each tub  10  has two wells  40  formed therein. The wells  40  on two nested tubs  10  abut each other so that the extent of the nesting is limited. The bottoms of the stacked tubs  10  are spaced apart by a predetermined distance. 
   The drain valve  28  in the tub  10  preferably is connected to a reservoir  42  or other container into which the blood, body fluids and decontamination material may be collected ( FIG. 14 ). The filled reservoirs  42  may be retained for future testing such as DNA or other identification procedures. It is preferred that a collapsible reservoir  42  be used to reduce storage space. Optimally, the filled reservoirs  42  may be moved to other locations for disposal. In extenuating circumstances, the drained fluid from the tub  10  may be directed to a berm or trench. 
   The decontamination system of the present invention can be used for any situation where there are bodies of victims of war, major accidents or catastrophic events. In some disasters, only body parts may be recovered. In the event of the use of hazardous substances such as chemical or biological agents, such as might occur in a military situation or a terrorist attack, it will be necessary to decontaminate the victims, their clothing and body parts to prevent the production of additional casualties of persons exposed to the contamination. 
   Persons in protective equipment including gas masks, gloves and protective clothing place the contaminated victims and/or body parts on the transfer sheet  34  or the stretcher  38 . The transfer sheet  34  may be placed on the stretcher  38 . The carrying means such as the transfer sheet  34  is placed in the tub  10  or the stretcher  38  is rested on the top of the tub  10  with the handles of the stretcher  38  received in the notches  18  in the tub  10 . The blood and other body fluids will drain through the porous material of the carrying means into the bottom of the tub  10 . The tub  10  should be tilted so that the fluids will collect at the ledge  22  in the one corner  20  of the tub  10  and, if needed, could be drained, through the drain valve  28  located at that corner, into the reservoir  42 . The fluids could be marked and placed aside for later identification. 
   The tub with the body/body parts may be placed on a roller system for transport to a decontamination station. The tub  10  may be placed on a litter stand or other support means. If hazardous materials are present, a supply of decontamination medium  44  is connected to a spraying device  46 . The decontamination material may be water with detergent or soap or a substance containing active chlorine or an approved decontamination formulation. Preferably, the spraying device  46  is hand held. Personnel in protective gear spray the decontamination material onto the body and/or body parts in the tub  10 . As shown in  FIG. 15 , one end of the stretcher  38  may be lifted to facilitate spraying from all directions. The engagement of the handles of the stretcher  38  in the notches  18  on the tub  10  allows the raising of one end of the stretcher  38  by one person with the other end of the stretcher  38  leveraged against the notches  18 . The body fluids, blood and decontamination material are drained from the drain valve  28  into the reservoir  42  after the body and/or body parts are removed. The decontaminated body and/or body parts is then moved to a clear area the body and/or body parts can be removed from the tub  10 . In an ongoing operation where there is a limited number of tubs  10 , a used tub  10  may be washed with a proper decontaminant and reused. 
   In situations where there are no hazardous materials, the tub, transfer sheet and stretcher may be used for bodies and/or body parts without the decontamination steps. This use is for events such as industrial accidents, airplane crashes, earthquakes and occasions where there are multiple bodies and/or body parts. The body fluids and/or bodies may be needed for forensic investigation. 
   Obviously, many modifications may be made without departing from the basic spirit of the present invention. Accordingly, it will be appreciated by those skilled in the art that within the scope of the appended claims, the invention may be practiced other than has been specifically described herein.
