Abstract
A liquid containment device for capturing and retaining any liquid falling into the device, such as from a leak, spill or run-off of another liquid container, where the device is designed to fit between the parallel rails of a railroad track with a railroad car positioned above, comprising a generally rectilinear pan or tray and gasket members sealing the space between the pan and the rails. Multiple pans may be connected in line through connector fittings in their end walls, or drain conduits may be connected to the fittings for removal of the liquid from the pan. Apertured grating members and absorbent mats may be placed within the pans. The pans may be used in conjunction with lateral pans positioned on the outside of the rails.
Claims23
A hazardous liquid capture and containment device comprising in combination a pan and longitudinally extending gasket members, and adapted for use between the opposing parallel rails of a railroad track, said rails each comprising a bottom member, a top member and a vertical member defining a generally I-shaped configuration;
- said pan comprising a bottom and adjoined side walls and end walls;
- said gasket members being disposed between said side walls and said vertical members of said rails in order to seal the area therebetween to prevent loss of liquid.
The device of clain 4, where said exterior member is a different height than said interior member.
A method of installing a hazardous liquid capture and containment device comprising in combination a pan and longitudinally extending gasket members, and adapted for use between the opposing parallel rails of a railroad track, said rails each comprising a bottom member, a top member and a vertical member defining a generally I-shaped configuration;
- said pan comprising a bottom and adjoined side walls and end walls;
- said gasket members being disposed between said side walls and said vertical members of said rails in order to seal the area therebetween to prevent loss of liquid, the method comprising:
- positioning said pan between said rails and inserting a first gasket member between one of said side walls and one of said rails;
- compressing said first gasket member by drawing said pan toward said one of said rails;
- inserting a second gasket member between the other of said side walls and the other of said rails;
- and
- releasing said pan such that said pan centers between said rails such that said gasket members are in a compressed state.
