摘要:
A portable chemical spill control device includes an expansive sheet of material (preferably multiple layers that include at least one layer of absorbent material) and having upper and lower surfaces and a periphery that defines a circumference. The sheet of material is of a material that is resistant to fluid attacks so that spills deposited upon the upper surface are contained on the upper surface. A peripheral bead includes a foldable portion that extends around the expansive sheet of material, the bead including an elongated tensile member and a folded portion that holds the elongated tensile member to the absorbent sheet of material. A connection joins the peripheral bead to the expansive sheet of absorbent material in a configuration that envelops the tensile member with the foldable portion. The elongated tensile member can be moved between open and folded positions wherein the tensile member subjects the expansive sheet of material to tension in an open position that maximizes its circumference, and wherein in the folded position the tensile member folds to provide multiple loops.
