Oil-resistant resilient mats to protect oil field workers from dangerous, high voltage electrical discharge comprise a first oil-resistant flexible resilient elastomer of extremely high dielectric strength which is usable by itself as a mat and also in combination with other oil-resistant elastomers of higher mechanical strength but less dielectric strength at high voltages and with metallic electrically conductive meshes to equalize mechanical and electrical stress across the first elastomer. The combination of metallic mesh and elastomer of high electrical resistance at high voltage provides mechanically strong and oil resistant mats that protect personnel in oil fields against high voltage and surges. The high mechanical strength elastomer layers mechanically protect the conductive wire mesh as well as the first elastomer.
