Available from J.T. Day, the EPR Safety Mat, manufactured from Lightning Protection International, is designed to keep workers safe against electrical discharge events, a significant hazard to personnel and equipment from earth potential rise (EPR). EPR can be caused by faults in electrical substation, power plants, high-voltage transmission lines or lightning strikes.
The mat has a three-layer design to mitigate Step and Touch volt hazards, which each have different roles. The central electrically conductive layer equalises the electrical potential across the mat, while the upper layer insulates. The lower layer is an electrically conductive elastomer that protects the central layer while providing electrical continuity to it.
The product’s layers are flexible to enable the mat to be rolled out where electrical repair work is to be carried out, and can also be joined electrically to create longer versions as required.
