Abstract
A storage container (2) having secondary containment venting by form of construction includes an primary container (4) defining a primary containment region (24), a secondary container (6) and an interstice (8) therebetween. A portion of the top (16) of the secondary container is weakened so that in the event of an overpressure within the interstice, the weakened region fails allowing the overpressure to be vented to atmosphere. Two bands (34, 36) of fluid-accepting and -conducting material are wrapped at an angle to one another around the primary container within the interstice. The bands of material help to ensure that any overpressure within the interstice is substantially equalized throughout the interstice so that if the secondary container does fail, it fails at the weakened region.
