Abstract
A conductive floor mat is disclosed for collecting process particles and grounding the electrostatic charge accumulated on operators who stand on the mat. The conductive floor mat includes a frame assembly, a plurality of parallel spaced ribs, a plurality of parallel spaced supports and grounding wires. The frame assembly includes four frame members and a bottom surface. At least one of the four frame members has an angled top surface. Both ends of the ribs and supports are mounted to the opposite of the frame members. The supports are perpendicularly fixed to the ribs for increasing the supporting capacity thereon. The grounding wires are extending from the frame assembly to discharge the electrostatic charge accumulated on the operators.
