ABSTRACT:
A transportation subassembly is provided for transporting a material that is destabilized in the presence of a destabilizing contaminant. The subassembly has a structural body having a cavity constructed and arranged to receive the material to be stored, a breather assembly operatively connected to the structural body and including a container forming a chamber, the chamber being in fluidic communication with the cavity and being constructed and arranged to receive an contaminant-removing material selected to remove the destabilizing contaminant, and a venting assembly mounted with respect to the structural body. The venting assembly includes a rupture apparatus rupturable at a predetermined pressure formed within the cavity to form fluidic communication between the cavity and the atmosphere. A method for transporting a material in a transportation subassembly is also provided. A structural body having a cavity for storing the material to be transported and a rupture apparatus rupturable at a pressure formed within the cavity is used. The method includes inspecting the cavity for defects and for destabilizing impurities; dry air purging the cavity; loading the material into the cavity; activating a breather assembly to restrict destabilizing impurities from within the cavity; operatively connecting a dry air line to the cavity to form fluidic communication between the cavity and the storage compartment; and maintaining the breather assembly in an activated position to maintain the cavity in a pure condition.
