Abstract: A security system for preventing ungrounded personnel access into an equipotential zone is described. The security system includes a conductive fence and a conductive mat. The conductive mat is mechanically and electrically coupled to the conductive fence to define an equipotential zone.

Abstract: Self-supporting equipotential grounding grates are used to create an equipotential zone for workers and equipment. The grates have a plurality of supports that cooperate to position the upper surface of a conductive grid above the surface on which the grates are used. The inner supports include upper and lower structural grids that allow debris to be readily removed from the grate after use. The grate supports workers and equipment. A plurality of the grates are electrically connected with cables to define a platform with the entire structure grounded with one or more grounding pins.

Abstract: A timber access mat having an electrical grounding feature includes an electrically conductive cover layer that is removably carried over the top of the body of the timber access mat. The electrically conductive cover layer can be formed from one or more sheets of expanded metal such as expanded steel. The layer is joined to a perimeter frame that includes offset connector tabs that allow mats to be positioned side-by-side. The connector tabs are paired with cable guides to protect the cable leads that connect the mats. The perimeter frame and conductive cover layer can be added to traditional timber access mats when electrical grounding is required and then removed and stored when not required.

Abstract: A device used with a traffic cone to support caution tape includes at least one head extending from a body. The head is received in the opening defined at the top of a typical traffic cone to support the device in an upright position with respect to the cone. The body of the device is adapted to support a section of caution tape. The body may define a slot that allows the tape to be supported in an unfolded condition.
