Container with secondary containment venting by form of construction

An above-ground storage container comprising:

• a secondary container having at least one surrounding wall which is integrally molded in one-piece and completely surrounds and continuously encloses the primary container, said surrounding wall having a top portion overlying the top;
• the secondary and primary containers defining an interstice therebetween;
• fluid-accepting and -conducting material within the interstice fluidly coupling portions of the interstice along fluid paths, adjacent to at least some of the side walls and bottom, to an upper portion of the interstice between the top and the top portion;
• and
• at least a part of the top portion being weaker than the remainder of said surrounding wall when subjected to a positive pressure within the interstice so that said part fails prior to said remainder when said interstice is subjected to an increasing positive pressure, thus providing a fluid escape passageway from the interstice to the ambient environment.

An above-ground storage container comprising:

• a primary container having a top, a bottom and side walls coupling the top and the bottom, the primary container defining a primary containment region therein;
• a secondary container enclosing the primary container and having a top portion overlying the top, the secondary and primary containers defining an interstice therebetween;
• at least a part of said top portion being weaker than the remainder of the secondary container when subjected to a positive pressure within the interstice so that said part fails prior to said remainder when said interstice is subjected to an increasing positive pressure, thus providing a fluid escape passageway from the interstice to the ambient environment;
• and
• fluid-accepting and -conducting material within the interstice fluidly coupling portions of the interstice, adjacent to at least some of the side walls and bottom, to an upper portion of the interstice between the top and the top portion, said fluid-accepting and -conducting material comprising at least two continuous bands circumscribing said primary container and crossing at said upper portion of the interstice.

An above-ground storage container comprising:

• a primary container having a top, a bottom and side walls coupling the top and the bottom, the primary container defining a primary containment region therein;
• a secondary container enclosing the primary container and having a top portion overlying the top, the secondary and primary containers defining an interstice therebetween;
• said secondary container comprising reinforced concrete and a high-density polyethylene liner;
• fluid-accepting and -conducting material within the interstice fluidly coupling portions of the interstice, adjacent to at least some of the side walls and bottom, to an upper portion of the interstice between the top and the top portion;
• and
• said reinforced concrete comprising rebar along side portions, a bottom portion and the top portion, the rebar along the side portions and the bottom portions being secured together, the rebar along the top portion being substantially unsecured to the rebar along the side portions at a junction region so said junction region is weaker than the remainder of the secondary container when subjected to a positive pressure within the interstice so that said junction region fails prior to said remainder when said interstice is subjected to an increasing positive pressure, thus providing a fluid escape passageway from the interstice to the ambient environment.
