36、egory.5.1.5 Care and UseKeep the outsoles clean. Do not add aftermarket insoles/inserts as doing so may affect conductivity.Dispose of the footwear if it becomes contaminated or no longer tests conductive, or both.5.2 Electric Hazard Resistant Footwear (EH):NOTE 2Electrical hazard protection is seve

37、rely deteriorated in the following conditions: excessive wear on the soling material or exposure to wet andhumid environments, or both. Work footwear can become contaminated with conductive materials. For example, soles can pick up metal shavings etc.which may reduce the effectiveness of the protect

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

43、the shoes and outsoles free of conductive materials such as screws, nails, and metal shavings. Dry the footwearthoroughly after use. Clean outsoles with a mild soap and warm water.To avoid cracking, store footwear away from electric motorsor electric fields Inspect footwear for any visible damage pr
