In processes handling flammable liquids, “flange jumpers” (also known as “bonding jumpers”) are critical safety components designed to maintain electrical continuity across piping joints. Since piping systems are often coated, gasketed, or subject to corrosion, a standard flanged connection may not provide a sufficiently low-resistance path to ground….

Leonard has described many papers and publications from the 1960s and 1970s addressing both the hazard and related safety…...
