Spill Containment Mat System

Abstract

A modular spill containment mat having a pan element and a support grating overlay. The pan element has one or more support beams under the grating to support a vehicle. A sidewall drain is provided, as well as openings in the grating for vacuum hose extraction. Each containment mat may be connected to one or more adjacent mats to form a larger mat. The containment mat may be used to prevent spills during refueling of vehicles.

1 . A modular spill containment mat, comprising:
 a rectangular pan having a bottom tray, first and second opposing side walls, and first and second opposing end walls;   a plurality of spaced structural beams extending between first and second side walls in parallel to the end walls, each beam having at least one opening along its lower edge adjacent the bottom tray; and   a grating reversibly connectable to the top of the pan, above the side walls, end walls, and beams;   wherein at least one side wall has at least one drain opening.   
     
     
         2 . The containment mat of  claim 1 , wherein the grating comprises opposing side sections separated by a central section, each of the side sections and central section separately removable from the containment mat. 
     
     
         3 . The containment mat of  claim 2 , wherein each side section of the grating further comprises at least one removable plate for insertion therethrough of a vacuum hose or other debris removal apparatus. 
     
     
         4 . The containment mat of  claim 1 , further comprising a locking means for releasably securing the grating to the pan. 
     
     
         5 . The containment mat of  claim 4 , wherein the locking means comprises an elongated channel iron connected to one end wall and reversibly attachable to a corresponding end of each section of the grating. 
     
     
         6 . The containment mat of  claim 1 , wherein the top surface of the grating is serrated. 
     
     
         7 . The containment mat of  claim 1 , wherein the grating has a thickness of between 1 and 4 inches. 
     
     
         8 . The containment mat of  claim 7 , wherein the grating has a thickness of 2 inches. 
     
     
         9 . The containment mat of  claim 1 , wherein each side wall is between 10 and 14 feet long, and each end wall is between 6 and 10 feet long. 
     
     
         10 . The containment mat of  claim 9 , wherein each side wall is 12 feet long, and each end wall is 8 feet long. 
     
     
         11 . The containment may of  claim 1 , further comprising at least one handle on the outside of each side wall and on the outside of each end wall. 
     
     
         12 . A spill containment system, comprising:
 a plurality of the spill containment mats of  claim 1 ;   latching means for connecting each containment mat to an adjacent mat side-to-side or end-to-end.   
     
     
         13 . The spill containment system of  claim 12 , wherein the latching means comprises an elongated angled plate attached at a first side along one side of a first containment mat, and releasably attachable along a second side to a side of a second containment mat adjacent to the first containment mat. 
     
     
         14 . The spill containment system of  claim 12 , wherein the latching means comprises an elongated angled plate attached at a first side along one end of a first containment mat, and releasably attachable along a second side to an end of a second containment mat adjacent to the first containment mat. 
     
     
         15 . A modular spill containment mat, comprising:
 a containment pan having a bottom tray, and a plurality of contiguous walls extending upwardly along each edge;   one or more spaced structural beams extending between at least one pair of the walls, each beam having at least one opening along its lower edge adjacent the bottom tray; and   a grating reversibly connectable to the top of the pan, above the walls and beams;   wherein at least one wall has at least one drain opening.   
     
     
         16 . The spill containment mat of  claim 15 , wherein the bottom tray is triangular. 
     
     
         17 . The spill containment mat of  claim 15 , wherein the bottom tray is pentagonal 
     
     
         18 . The spill containment mat of  claim 15 , wherein the bottom tray is hexagonal.
