WO 2004/052748 PCT/AU2003/001653 Apparatus For Contained Inspection And Transportation Of Suspect Objects 5 Technical Field The present invention relates to an apparatus or device for the contained inspection and transportation of objects suspected of being potentially dangerous, and in particular, to an apparatus for the contained inspection and possible subsequent transportation of envelopes, mail, packages, parcels, letters and the 10 like, suspected of containing potentially dangerous substances. Background Art Subsequent to the terrorist activity of 11 September 2001 in the United States and the subsequent anthrax contaminated envelopes entering the mail system in the 15 United States, many other countries have also experienced a spate of envelopes being received via the mail system which contain suspicious white powder. Prior to being able to determine whether or not the white powder is a dangerous substance a response procedure is required to be initiated for safety reasons. The 20 response procedure requires a full hazardous material handling procedure to be initiated by relevant emergency response authorities. The affected area, including all affected persons, are generally required to be contained until such time as the results of the analysis of the unknown substance becomes available. Such incidents result in stress and trauma to the affected persons, considerable loss of 25 productivity and ties up emergency service resources. Given that it is relatively simple for an antagonist to insert a substance into an envelope, or any other similar package, which is often a harmless white powder, there is a need to provide a response procedure utilising apparatus that lessens the 30 impact on affected persons, productivity and emergency services.
-lA DE 201 17 239 (Ul) discloses a container for inspection of mail 3. The container is provided with gloves I for a user's hands, and has a lid 4. DE 201 17 239 (UI) does not suggest that the container is adapted to be moved or transported if 5 hazardous material is suspected. Neither does DE 201 17 239 (Ul) disclose or suggest any additional container Ihat can be readily transported safely. Moreover, DE 201 17 239 (Ul) does not disclose or suggest a sealed airtight environment within the container. 10 The reference in this specification to any prior publication (or information derived from it), or to any matter which is known, is not, and should not be taken as an acknowledgment or admission or any form of suggestion that that prior publication (or information derived from it) or known matter forms part of the common general knowledge in the field of endeavour to which this specification 15 relates.
WO 2004/052748 PCT/AU2003/001653 -2 Laboratory "glove-box" type products are known that allow a user to insert his or her forearms and hands into gloves, allowing the user to safely handle objects within the glove-box. Such laboratory glove-boxes are bulky and are not designed to be transportable. Furthermore, they are typically also relatively 5 expensive. Other styles of glove-boxes are constructed of plastic sheeting and require frames and inert gases to inflate them, which further complicates the procedure for safe handling of potentially dangerous objects. In addition, presently known glove-boxes are not robust and portable which is a significant disadvantage. 10 This identifies a need for apparatus for the contained inspection and possible transportation of potentially dangerous objects which overcomes or at least ameliorates the problems inherent in the prior art. 15 Disclosure Of Invention The present invention provides an examination, isolation and transportation apparatus/device for suspicious objects, for example, suspicious mail that may potentially contain or be contaminated by dangerous biological or chemical agents.

Modes For Carrying Out The Invention The following modes are described in order to provide a more precise 20 understanding of the subject matter of the present invention and should not be considered as limiting the scope of the present invention. In the figures, incorporated to illustrate the features of the present invention, like reference numerals are used to identify like parts throughout the figures. 25 In a preferred embodiment apparatus is provided which allows a user to examine suspicious mail or the like in an airtight or sealed environment, whereby the mail and its contents can be visually examined within the airtight environment. If further analysis of the mail and/or its contents is required the mail can be maintained in the airtight environment and transferred to a second airtight or 30 sealed environment which provides important additional protection during transportation to a specialist analysis site, for example a biochemical or forensic laboratory.
WO 2004/052748 PCT/AU2003/001653 -6 Referring to figures 1 to 7, when a potentially dangerous object (not illustrated) is received and identified as being potentially dangerous, the object is placed in the inspection unit 10. To place the object in the inspection unit 10 the lid section 11 is removed or opened and the object placed in or on the base section (or 5 alternatively body section) 12 of the inspection unit 10. The lid section 11 is then sealed against the base section 12 to provide a sealed environment containing the object. The extent of the height of the lid section 11 or the base section 12 can be varied. For example, the shapes of the lid section 11 and the base section 12 may be substantially interchanged so that the base section 12 can be considered as a 10 body section having a substantial height. Alternatively, the lid section 11 and the body or base section 12 could be provided to be similar depths. After examination of the object within the inspection unit 10, should the user believe that further analysis of the object or its contents is required, the 15 inspection unit 10 is then wholly placed within a transportation unit (illustrated in figure 8). The inspection unit 10 is placed into a body section of the transportation unit after which a lid section of the transportation unit is sealed to the body section, thereby providing a further sealed environment that completely contains the inspection unit 10. 20 The potentially dangerous object is hence contained within two separate sealed environments and can then be relatively safely transported to an analysis site. Both the inspection unit and the transportation unit are preferably of a suitable size and material so that they are portable allowing ease of transportation of the 25 potentially dangerous object to the analysis site. Referring further to figures 1 to 7 wherein various views and features of the inspection unit 10 are illustrated, the lid section 11 is preferably provided as an enclosure assembly that is substantially transparent allowing the user to visually 30 inspect the potentially dangerous object. Parts of the lid section 11 may be opaque or the lid section 11 may be substantially totally manufactured from a transparent material, for example a transparent plastic. Regions of the base section 12 may also be transparent, but preferably, the base section 12 is substantially opaque, preferably of a dark colour such as black or dark blue. This WO 2004/052748 PCT/AU2003/001653 -7 assists the user in visually identifying a white powder against a dark background. Regions of the lid section 11 may similarly be a dark colour if desired. Preferably, the inspection unit 10 is substantially made of a moulded plastic(s). 5 The lid section 11 and the base section 12 are adapted to be clamped or closed together using clamp or latch means. In the preferred embodiment, two cranked hinges 13a and 13b are attached to the base section 12 and the lid section 11 to allow these sections to be joined together but rotatable with respect to each other. Draw latches 14a and 14b are also provided on the lid section 11 and associate 10 with keepers or protrusions 15a and 15b, respectively, that are provided as part of, or attached to, the base section 12. When the lid section 11 is rotated to close against the base section 12 the latches 14a and 14b can be closed against the keepers 15a and 15b to seal the inspection unit 10. It should be noted that a varying number or variety of latch or clamp means can be utilised as required. 15 For example, latches or clamps can be provided at different locations on the inspection unit and hinges 13a and 13b could be replaced with further clamps or latches. The clamp or latch means may be any type of device, or mixture of devices, which assist to secure or attach the lid section 11 to the base section 12 to provide a sealed environment internal to the inspection unit 10. 20 A tray 16 is also preferably provided on or integrated with the base section 12. The tray 16 may be fixed or removable. A seal or base gasket 17 is preferably provided associated with the base section 12, and a further seal or lid gasket (not illustrated) is preferably provided associated with the lid section 11. These seals 25 or gaskets are provided at or near the interface between the lid section 11 and the base section 12 and abut each other when the inspection unit 10 is closed to assist in providing an air tight environment within the inspection unit 10. Alternatively, a single seal or gasket only might be provided associated with either the lid section 11 or the base section 12. 30 When the inspection unit 10 is closed the user then inserts both forearms/hands through the hand access orifices 18a and 18b so that glove members (not illustrated) attached to the hand access orifices 18a and 18b and internal to the inspection unit 10 are fitted over the users hands. The user is then able to use his WO 2004/052748 PCT/AU2003/001653 -8 or her hands to manipulate the object within the sealed environment of the inspection unit 10 without breaching the sealed environment. The lid section 11 can also be provided with a magnifying section on the top 5 surface so that when the user visually inspects the object within the inspection unit 10 the contents of the inspection unit 10 are magnified to the eyes of the user. The inspection unit 10 can also be provided with an inspection port assembly 21 10 which can be sealed but provides the possibility to be used as a further access point to manipulate an object within the inspection unit 10. Preferably, glove members (not illustrated) are attached to access regions 18a and 18b, and possibly 21, however, it should be noted that any other type of device which allows a user to inspect and/or manipulate the object within the inspection unit 10, without 15 breaching the sealed environment, could be utilised. Furthermore, a plug assembly or port 22 can be provided as illustrated. The plug assembly 22 could be utilised for a variety of purposes. In a particular embodiment, the port 22 is approximately 40mm in diameter and allows fire and testing authorities a small port through which chemical or radiological probes can sample the contents of the unit 10, 20 without having to open the main seal. The unit has been tested for compatibility with equipment such as the AP2C, PID (Photo lonisation Detectors), the Bruker raid for chemicals, the Exploranium GR135 and Rotem R200 for radiological substances. The unit may be taken to a controlled area where the rear port can be opened and testing performed. The plug 22 is then replaced, and if required, the outside of the unit 10 flushed down to 25 remove any possible escaped contaminant. Use of decontamination foam or solutions is also possible. The larger port 21 is preferably just over 100mm in diameter and is provided so that when the unit 10 is in a Biosafety cabinet access can be gained via port 21 instead of opening the main seal. Port 21 is large enough for a gloved hand or small equipment to be passed into the unit 10, again to reduce the exposure risk to the operator. 30 Other uses of port 22 are also possible, for example, to equalise air pressure to facilitate opening of the inspection unit 10, to be attached to tubing or the like so that air may be removed from the inspection unit 10, for example to create a vacuum, to introduce a suitable gas into the inspection unit 10, or as a general purpose point of further access. It should be noted that both the inspection port WO 2004/052748 PCT/AU2003/001653 -9 assembly 21 and the plug or port assembly 22 need not necessarily be provided or can be provided in alternate locations or configurations. It should also be appreciated that if the lid section 11 is substantially planar and the base section 12 is provided with most of the height of the inspection unit 10, then the access 5 orifices 18a and 18b would obviously be provided as part of the base section 12. Referring to figure 8, this figure illustrates an exploded perspective view of a preferred embodiment of the transportation unit 80. The transportation unit 80 includes a lid section 81 and a base or body section 82 which join together to 10 provide an air tight environment when the lid section 81 is engaged with the body section 82. As discussed for the inspection unit 10, the depth or height of the lid section 81 and the body or base section 82 can be varied, for example body section 82 could be substantially planar and lid section 81 could be provided with walls having substantial height. Also similarly as for the inspection unit 10, the 15 transportation unit 80 is preferably provided with hinges 83a and 83b that fixedly attach to the lid section 81 and the body section 82 allowing the lid section 81 to rotate and close against the body section 82. Latches 84a and 84b are provided attached to the body section 82 and fix against hooks or protrusions 85a and 85b (see figure 12) attached to or integrated with the lid section 81. Also as discussed 20 previously, the type, configuration, or combination of clamps, latches, hinges, etc. can be altered or varied as desired. Also illustrated in figure 8 is a handle 86 fixed to the lid section 81. A further handle 87 can be provided to attach to protrusions 88a and/or 88b which assist a 25 user with lifting or carrying the transportation unit 80. Furthermore, the transportation unit 80 can be provided with wheels 89a and 89b, fixed by a rod or axel 90 to the body section 82, that may assist with transportation of the transportation unit 80. Seals or gaskets 91 and 92 can also be provided associated with the lid section 81 and the body section 82, respectively, to assist in providing 30 an air tight environment when the lid section 81 is engaged with the body section 82. Various indicia 93 can be provided on the transportation unit 80 indicating its contents may present a chemical or biological hazard.
WO 2004/052748 PCT/AU2003/001653 -10 It should be appreciated that a variety of mechanisms to seal lid section 81 against body section 82 can be envisaged. For example, hinge and latch means may not be provided but the lid section 81 may be adapted to press-seal against the body section 82. Any mechanical structure that allows the lid section 81 to affix, 5 engage, secure, lock or the like with the body section 82, and provide a sealed environment, can be utilised in the present invention. The transportation unit 80 is preferably made of a resilient plastic so that it can withstand external forces and/or shocks. Furthermore, the transportation unit 80 10 may be provided with internal padding and/or shock absorbing material. This assists in insulating the inspection unit 10 from damage or breach during transportation of the potentially dangerous object to the analysis site. Furthermore, the transportation unit 80 could be provided with locking means to prevent unauthorised access to the potentially dangerous object. In a particular 15 form, the transportation unit 80 is fitted with two independent airtight seals and is double walled and insulated. In combination with the inspection unit 10 the apparatus thus provides a triple walled containment system with three independent airtight seals. 20 The following further example provides a more detailed outline of an embodiment of the present invention. The example is intended to be merely illustrative and not limiting to the scope of the present invention. The apparatus for the contained inspection and transportation of suspect objects 25 provides a light-weight, airtight and durable unit for the examination and transportation of mail suspected to contain a hazardous substance, for example a powder substance. The apparatus is preferably made of moulded plastic consisting of a tub-like lid which is provided with side entry portals for a user's hands to slip into built-in gloves. The base of the apparatus is preferably dark 30 (black or dark blue) to provide the best contrast against a light coloured powdered substance. A moulded base section is fitted with an airtight seal and is further secured to the lid by locking clamps which should be able to survive dropping or other impacts intact. The lid section is transparent and is optionally provided WO 2004/052748 PCT/AU2003/001653 -11 with an in-built magnifying section allowing magnified examination of suspect mail. Implements can be left within the apparatus for use by the user when inspecting 5 mail. For example, a round-end flat blade letter opener could be provided. The total weight of the apparatus is preferably able to be easily handled without risk of the integrity of the sealed environment being breeched. A transportation unit of the apparatus receives the inspection unit and thus provides double-wall security during transport in the event of dropping or an accident occurring. 10 Safety instructions and a preferred procedure to follow in the event of the receipt of suspicious mail can be provided to complement the apparatus. The inspection unit is designed to allow the safe examination of mail, including larger envelopes, for example A4 size and small parcels, in a wholly contained 15 environment. Once mail is identified as being suspicious and is believed to contain a hazardous material, for example a powder substance, the mail is placed into the inspection unit and the lid section is closed and locked. The suspicious mail is then opened or further inspected in the inspection unit with the user provided with a clear view through the lid section. If the mail contains any 20 contaminant the inspection unit is then wholly placed within the transportation unit and transported to a suitable examination laboratory or analysis site by the appropriate personnel. This process also reduces the number of persons handling the suspicious mail thereby allowing preservation of possible forensic evidence. 25 Components of the apparatus are preferably single pieces of moulded plastic, the glove members could be vinyl gloves or made from any other suitable material. The transportation unit would preferably be clearly marked as containing bio hazardous material. Seals used in the apparatus could be soft rubber seals. Padding or restraining devices can be provided internally to the transportation 30 unit to assist in providing physical protection and/or stability for the inspection unit. The inner inspection/containment unit can be designed to handle various sizes of suspicious mail, for example A4 size envelopes. Units of other dimensions can WO 2004/052748 PCT/AU2003/001653 -12 also be provided. In a particular preferred form the gloves are nitrile gloves, which have high chemical and abrasive resistance and do not expose the user to the risk of a latex reaction. In the preferred embodiment, the inspection unit weighs approximately three kilograms and is generally robust. 5 The outer transportation unit is built to high standards and is designed to cradle the inner inspection unit during transportation and to provide maximum protection of the inner inspection unit and its contents. The transportation unit may be of high visibility yellow colour and clearly marked as containing a potentially 10 biological or chemical hazard. In this embodiment, the transportation unit is designed to withstand falls from up to three metres without damage to the contents, and the combined weight of the two units is approximately thirteen kilograms. 15 Thus, there has been provided in accordance with the present invention, apparatus for the contained inspection and, if required, transportation of potentially dangerous objects. The invention may also be said to broadly consist in the parts, elements and 20 features referred to or indicated herein, individually or collectively, in any or all combinations of two or more of the parts, elements or features, and where specific integers are mentioned herein which have known equivalents in the art to which the invention relates, such known equivalents are deemed to be incorporated herein as if individually set forth. 25 Although the preferred embodiment has been described in detail, it should be understood that various changes, substitutions, and alterations can be made herein by one of ordinary skill in the art without departing from the scope of the present invention. 30
