Abstract: The invention provides secondary contaiment for liquid carrying equipment which is in a confined area. The invention is especially well suited for retrofitting manholes containing pumps for underground gasoline distribution systems. The pumps or other equipment are removed to expose pipes or wires entering the manhole. Then, plates are bolted around the pipes or wires to engage and support a bag made of a material which resists the attack of the liquid. Holes are cut in the bag to pass the pipes or wires. The bag is placed in the hole, expanded to approximately fill hole, to rest on the plates, and is sealed to the plates, pipes, or wires. The top of the bag is gathered and closed to resist entry of ground water.

Abstract: A dispenser pan for collecting fluids spilled under a gasoline dispenser (pump). The pan may be installed without necessarily requiring a removal of the dispenser from its underlying supporting structure. The pan is made of a flexible membrane which may be stuffed through a hole in a cement island supporting the dispenser, worked into position, and then anchored in place. A pocket is formed on the bottom of the membrane in order to form a sump and in order to receive a shear valve on the bottom of the sump.
