Shield apparatus

A shield apparatus, comprising,

• a first block, a second block arranged for mounting to a first top surface of the first block,
• and
• a third block arranged for mounting to a second top surface of the second block,
• and
• the first block, the second block, and the third block are each of a predetermined length and are each of a predetermined width,
• and
• the first block includes a first block cavity, the second block includes a second block cavity, and the third block includes a third block cavity, wherein the first block cavity, the second block cavity, and the third block cavity are each in fluid communication relative to one another when the first block, the second block, and the third block are mounted relative to one another, and
• the first block includes a first floor and first top wall, with the first top wall spaced from and parallel the first floor, the first top wall includes a first rib coextensively directed along the first top wall and wherein the first block includes parallel first side walls and parallel first end walls, with the first rib extending orthogonally between the first end walls, and one of said first side walls includes a drain conduit directed therethrough in fluid communication with the first cavity, the drain conduit including a valve member arranged for effecting selective fluid flow through the drain conduit, and the first rib including a first rib top wall arranged parallel to and spaced above the first top wall, the first rib top wall including a first bore directed therethrough spaced from one of said first end walls a predetermined spacing, and a continuous torroidal "O" ring mounted in surrounding relationship relative to the first bore and secured to the first rib top wall extending above the first rib top wall.
