Chemical spill containment apparatus

Abstract

New and improved spill containment devices and methods, for use primarily by the railroads, are provided in one or more lidded catch pans positionable generally around and under a transportation container for collecting and containing spilled or dripping chemical materials. A preferred spill containment apparatus comprises a combination of three catch pans positionable along a railroad siding including an inboard pan disposed between the rails and two outboard pans extending outwardly adjacent and alongside the rails and the inboard pan. The outboard pans have sectional lids that swing back over the railroad rails. This not only protects the area from splashing caused by heavy dropping in the big center pan, but also ensures that drips from above do not land on the rails or the gap between the inboard pan and the rails. When not in use, these sloped sectional lids divert dirt and rainwater away from the outboard receptacle or collecting basin portions of each outer pan. The inboard pan is designed to cover the space between the rails and still allow space for the flange of the railroad car or locomotive wheel to pass around the pan. The lid of this pan is designed to slope so rainwater will run off the lid. The lid is made in two sections. Each section is on a confined roller track that parallels the railroad rails. For normal use, these lids are rolled apart exposing whatever space is deemed to be needed to catch any overflow or inadvertent release.
