Portable fluid containment pad

A portable fluid containment pad, comprising:

• a pan having an interior fluid containment cavity with a bottom, a first side, a second side, and opposed ends;
• structural load bearing “I” beams which rest upon the bottom of the pan and extend between the opposed ends in parallel spaced relation to the first side and the second side and to each other, including a first structural load bearing beam positioned along the first side, a second structural load bearing beam positioned along the second side and at least one central structural load bearing beam positioned between the first structural load bearing beam and the second structural load bearing beam, the maximum span between each of the structural load bearing “I” beams being less than three feet, and each of the structural load bearing “I” beams having a plurality of transverse drainage passages to accommodate fluid flow;
• a plurality of transverse “I” beams which extend between the first side and the second side in parallel spaced relation to the opposed ends and to each other, the maximum span between the transverse “I” beams being less than three feet, gaps being provided below each of the transverse beams to accommodate fluid flow along the bottom of the pan;
• a rigid grating substrate supported on a substantially horizontal plane by the structural load bearing “I” beams;
• a fluid containing first appendage on the first side and a fluid containing second appendage on the second side, each of the first appendage and the second appendage extending upwardly and outwardly from the first side and the second side of the pan, respectively, adjacent to the bottom and terminating at the substantially horizontal plane, the rigid substrate extending past the first side and the second side to cover the first appendage and the second appendage, respectively, the first appendage on the first side of the pan having a projecting lip which extends between the opposed ends and the second appendage on the second side of the pan having a recess which extends between the opposed ends, the lip engaging the recess to enable adjacent pans to be connected in side by side relation while maintaining fluid containment to prevent leakage between the adjacent pans;
• and
• fittings with hose couplings in the pan, such that the pan can rapidly be adapted to be in fluid communication with another pan by connecting hoses to the hose couplings.
