A secondary or spill containment pallet that is the combination of a base or reservoir member composed of a flexible, non-self-sustaining material, one or more horizontally disposed apertured deck members, and an internal load-bearing support structure capable of supporting the deck member and liquid containers disposed on the deck members. The support structure maintains the deck members a suitable distance above the bottom of the base member such that a large internal volume is created, whereby liquid leaking or spilling from the containers will be received and retained within the base member, the walls of which are suspended from or attached to the deck members.
