The present invention relates to a device for transporting and storing of a powder or liquid medium, comprising (a) a structurally stable outer container having an electrically conducting inner surface, a top side that is open and capable of receiving an inner container, and a bottom section comprising a plurality of recesses wherein each recess can receive a pronged platform of a cargo moving device; and (b) an inner container capable of holding said medium having a top section, an opening in said top section for filing and discharging said medium, and one or more walls. These walls are made of a plastic material, are adjacent to said inner surface of said outer container, and have an outer surface. The outer surface has at least one electrically conductive layer that is in electrical contact with the outer container's inner surface. Moreover, invention could optionally include a plastic pallet having an electrically conductive layer that is in contact with the outer container.

The invention claimed is: 1. A device for transporting and storing a powder or liquid medium, comprising: a structurally stable outer container comprising (i) at least one wall constructed of a supporting plastic layer and having an electrically conducting inner surface and an electrically conducting outer surface that are in mutual electrical contact, (ii) a top side that is open and capable of receiving an inner container, and (iii) a bottom section comprising a plurality of recesses wherein each recess is capable of receiving a pronged platform of a cargo moving device; and a thin-walled inner container disposed within said outer container, said inner container comprising (i) top section having an opening for filling and discharging a liquid or powder medium, (ii) at least one wall having a non-conductive plastic inner layer having a thickness of no more than 3 millimeters, and (iii) an electrically conductive outer layer having a surface in electrical contact with said outer container's inner surface, wherein said electrically conductive surfaces are constructed of a mixture of plastic material and an electrically conductive filler. 2. The device according to claim 1, further comprising a plastic pallet having an electrically conductive layer, said electrically conductive layer being in contact with said outer container. 3. The device according to claim 1, further comprising a covering element attached to said outer container capable of covering said inner container. 4. The device according to claim 1, wherein said at least one electrically conductive surface of said outer surface of said inner container has an electrical resistance of equal to or less than 107 Ohms. 5. The device according to claim 1, wherein said wherein said electrically conductive inner surface of said outer container has an electrical resistance of equal to or less than 107 Ohms. 6. The device according to claim 1, wherein said electrically conductive outer surface of said outer container has an electrical resistance of equal to or less than 107 Ohms. 7. The device according to claim 1, wherein said inner layer of said inner container releases less than 100 parts-per-trillion of each metallic impurity into a medium in the inner container.
