Abstract: 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.
