ABSTRACT:
The invention contemplates a multi-layer electrically conductive web or mat for safely and quickly discharging personnel-accumulated static electricity. An upper continuous polymeric layer of relatively low conductivity, in the order of 10.sup.8 ohms per square, is bonded to an underlying continuous polymeric layer of much greater conductivity, in the order of 10.sup.2 ohms per square, and provision is made for electrically grounding the underlying layer, illustratively by casting to the intermediate layer a continuous bottom layer of expanded polymeric material of relatively low conductivity.
