Patent ID: 7234608

Claim:
A spill containment assembly for containing fluid spilled or leaked from a vessel, comprising: a flexible bag having a bottom and a sidewall that cooperate to define a volume, the bag sidewall having an upper flap portion that defines an opening, wherein said flexible bag is non-self supporting such that said sidewall and upper flap portion normally collapse onto said bottom and rest upon said bottom; and a rigid grate having a perforated structure including a perforate upper surface and a perforate lower surface, said grate being sized and adapted to be inserted into said flexible bag via said opening in the upper flap portion, and wherein, once said grate is received within the bag, said grate occupies a portion of said bag volume, said upper flap portion rests upon a peripheral portion of the grate upper surface, and said grate lower surface rests upon the bag bottom such that said grate supports said upper flap portion and said sidewall in a spaced relation to said bag bottom and thereby renders a remaining portion of said bag volume available to receive fluid, said grate upper surface being exposed and accessible via said opening such that the vessel may be disposed on the grate upper surface so as to extend above said bag opening, said grate perforated structure allowing fluid spilled or leaked from the vessel to flow into the grate, from the upper surface toward the lower surface, while said bag contains such leaked or spilled.
