Abstract
Spill containment apparatus especially adapted for use at a railroad siding to catch inadvertent chemical spills includes a shallow, rectangular pan having upstanding, opposed sidewalls and upstanding, opposed endwalls. Flaps are pivotally connected to the sidewalls near the upper edges thereof. The flaps can be moved from a first position where they are stored inside the pan to a second position where they extend laterally outside the pan and over the railroad tracks. A longitudinally movable cover is provided for the pan, the cover being mounted on tracks for back and forth movement between a first position where the pan is covered to a second position where the pan is exposed. In the second position of the cover, the flaps are permitted to move between their first and second positions. Because the flaps can be stored inside the pan, the size of the pan when not in service is relatively small. Because the flaps can be extended in use, the effective surface area protected by the pan is quite large.
