1. An equipotential zone matting for a work site and on which equipment and workmen will be operating, wherein the work site is or may be in an energized working environment, the equipotential zone matting comprising: a wire mesh constructed of electrically conductive, flexible elongate members which, when the wire mesh is in a closed and planar position, are parallel and adjacent to one another and at connection points connected each to an adjacent one of the elongate members by a spaced apart array of electrically conductive connectors to form the connection points of the wire mesh, wherein the electrically conductive connectors are adapted to reduce stress concentrations in the flexible elongate members at their connection points, wherein a first said spaced apart array of the electrically conductive connectors are spaced apart in a first position as between first and second adjacent elongate members, and wherein a second said spaced apart array of the electrically conductive connectors are spaced apart in a second position as between second and third adjacent elongate members, wherein the first and third adjacent elongate members are positioned on opposite sides of the second elongate member so that the first and second spaced apart array of the electrically conductive connectors alternate between the first and second positions in alternating elongate members so as to be spaced apart from one another when the wire mesh is in an open and planar position with the elongate members tensioned in a plane perpendicular to longitudinal axes of the elongate members, and wherein the plane contains the elongate members, when the wire mesh is in the closed position.
