The present invention pertains to a method of packaging hazardous liquids for shipment or containment, and to the structure and composition of the packaging which can be used to practice the method. The method comprises packaging a hazardous liquid for shipment or containment wherein the hazardous liquid, present in at least one sealed container or in a leaking container, respectively, is placed in a package which can be sealed so that the package completely surrounds and isolates the container, wherein the improvement comprises: constructing the packaging material so that it comprises at least two layers, including an interior layer and an exterior layer, wherein the interior layer of the packaging material adjacent to the sealed or leaking container can be penetrated by liquid which escapes from the container, and wherein the exterior layer of the packaging material, the external portion of which is in contact with the external environment, is impermeable by the liquid and by hazardous vapor therefrom. Typically, the packaging material is comprised of three layers, the interior, permeable layer, an adjacent layer which comprises an absorbent or adsorbent, and the exterior impermeable layer.
