In step potential environments, dielectric overshoes should be used.5.2.1 Electric hazard footwear shall be constructed and manufactured so that the footwear outsole can provide a supplementalform of protection to the wearer from hazardous step potential (the difference in electrical potential

39、between the feet) whilestanding on the ground.NOTE 3Electrical hazard protection is severely deteriorated in the following conditions: excessive wear on the soling material, contamination byconductive materials, or exposure to wet environments. In wet environments where the protective qualities of t

40、he footwear are compromised and wherethere is a step potential hazard, Dielectric overshoes should be used. In addition, a variety of methods such as maintaining appropriate distances, use ofisolation methods, use of grounding methods for step voltage control, etc. should be considered to provide pr
