SECONDARY CONTAINMENT RESERVOIR DEVICE

摘要

A secondary containment reservoir device (20) having a bottom (18) and side walls (11) forming a reservoir (13), and communicating with the reservoir (13) an expandable retention means (21) such as a bladder which automatically expands to receive liquid from the reservoir (13), allowing the total capacity of the device (20) to greatly exceed the capacity of the reservoir (13) alone. The device (20) can be adapted to receive or support any type of primary liquid container above the reservoir (13), including drums, barrels, tanks, IBC's, tanker vehicles, tanker trailers or railroad tankers. In one embodiment, the reservoir (13) is formed within a pallet having a support deck (12) to receive drums or barrels of liquid. A single bladder or multiple bladders may be used, and the bladders may be mounted internally or externally.
