A cargo container and method for transporting hazardous material includes a housing, a frame, and a lid, or, alternatively a door. The frame and housing define an opening and an interior storage space for containing the hazardous material. The lid or door is operatively connected to the frame and covers the opening for inhibiting access to the interior storage space. A first gasket fluidly seals the lid or door for inhibiting hazardous material from moving from the interior storage space to an outer environment. Additionally, the cargo container may include a second gasket, a seal arrangement, and/or a tortuous path for deflecting airborne hazardous materials from the first gasket and further inhibiting hazardous material from moving from the interior storage space to the outer environment.

1. A cargo container for transporting hazardous materials, comprising; a housing connected to a frame, the frame and the housing defining an opening and an interior storage space, the interior storage space being accessible through the opening;a lid operatively connected to the frame, the lid covering the opening for inhibiting access to the interior storage space through the opening;a flange operatively connecting to the frame and positioned adjacent to the lid covering the opening, the flange generally surrounding the opening;a first gasket positioned on the flange and generally surrounding the opening, the first gasket sandwiched between the flange and the lid for fluidly sealing the lid to the flange for inhibiting hazardous materials from moving from the interior storage space to an outer environment; anda tortuous path at least partially defined by the housing and extending from the interior storage space to the first gasket, and at least one aspect of the tortuous path being a groove generally surrounding the opening,wherein at least the housing is configured to deflect at least a portion of air borne hazardous materials away from the first gasket such that the tortuous path further inhibits passage of hazardous material from the interior storage space to the outer environment. 2. The cargo container of claim 1 wherein the groove is further defined by a portion of the lid. 3. The cargo container of claim 2 the lid includes an inner panel defining an air bladder such that the inner panel and air bladder further define the groove. 4. The cargo container of claim 1 wherein the first gasket is attached to the lid and further comprises: a second gasket attached to the flange, the first and second gaskets sandwiched together and offset from each other for higher friction and contact between the gaskets. 5. The cargo container of claim 4 wherein the first and second gaskets are respectively attached to the lid and flange via pressure sensitive adhesive. 6. The cargo container of claim 1 further comprising: a support surface generally surrounding the opening and positioned proximate to the flange such that the support surface further defines the groove. 7. The cargo container of claim 1 further comprising a seal arrangement positioned adjacent to the interior storage space and covering the opening for further deflection of air borne hazardous materials away from the first gasket. 8. The cargo container of claim 7 where at least a portion of the seal arrangement is positioned within the groove for supporting the seal arrangement across the opening. 9. The cargo container of claim 8 wherein the seal arrangement further comprises: a sheet material having an edge portion; andan extension member connected to the edge portion of the sheet material and configured to rigidly extend the edge portion of sheet material,wherein the extension member removably inserts into the groove for supporting the seal arrangement across the opening. 10. The cargo container of claim 9 wherein the seal arrangement further comprises a plurality of pockets, the plurality of pockets receiving the extension member for holding the extension member therein. 11. The cargo container of claim 10 wherein the extension member is a fiberglass pole. 12. A cargo container for transporting hazardous materials, comprising; a frame and a housing, the frame and the housing defining an interior volume, the interior volume being accessible through an opening;a door connected to the frame and adjacent to the opening such that the door is movable between an open position and a closed position;a locking mechanism connected to at least one of either the door or the frame, the locking mechanism interlockable to seal the door to the frame;a seal arrangement being closable at an opening and positioned within the interior volume to define an interior storage volume, the interior storage volume being accessible via the closable opening;a first seal being between the frame and the door and surrounding the entirety of the opening; anda second seal sealing the closable access opening of the seal arrangement,wherein the first seal sufficiently seals the interior to inhibit the escape of hazardous materials therethrough. 13. The cargo container of claim 12 wherein the seal arrangement includes a plurality of flaps at the opening, and the plurality of flaps configured to connect for sealing the seal arrangement closed. 14. The cargo container of claim 13 wherein at least a portion of the flaps connect via hook and loop fasteners. 15. The cargo container of claim 14 wherein at least another portion of the flaps further connect via a zipper. 16. A method of containing hazardous materials within a cargo container, the cargo container having a frame, a housing, and a door, the frame and the housing defining an interior volume, and the interior volume being accessible via the door through an opening, the method comprising; creating a first seal between the door to the frame in a closed position in order to cover the opening and sufficiently seal the interior volume from an outer environment;creating a second seal with a seal arrangement between the door and the interior storage space in order to further cover the opening; anddeflecting airborne hazardous materials with the seal arrangement from the first seal for inhibiting passage of hazardous material from the interior volume to the outer environment;wherein the seal arrangement is a tarp arrangement having a plurality of flaps, and creating the second seal further comprises:overlapping the flaps; andsealing the flaps together via a plurality of hook and loop fasteners and a zipper. 17. A method of containing hazardous materials within a cargo container, the cargo container having a frame, a housing, and a lid, the frame and the housing defining an interior storage space, and the interior storage space being accessible through an opening, the method comprising; sealing the lid to a flange via a gasket in order to cover the opening and sufficiently seal the interior storage space from an outer environment;defining a tortuous path with at least the housing from the interior storage space to the gasket; anddeflecting at least a portion of air borne hazardous materials away from the gasket with at least the housing such that the tortuous path further inhibits passage of hazardous material from the interior storage space to the outer environment;wherein sealing the lid to the flange further comprises:sandwiching the gasket against another gasket; andoffsetting the gaskets for higher friction and contact therebetween for further inhibiting passage of hazardous material. 18. The method of claim 17 wherein deflecting at least a portion of airborne hazardous materials further comprises: covering the opening with a seal arrangement between the lid and the interior storage space.
