When a qualificd person is working in the vicinity of overhead lines,whcttmr in an I <br /> elevafed position or on the ground,the person shall not approach or�akc any conductive objcct without an <br /> approved insulating handle closer to exposed energiud parts than shown in subsections(3)and(4)of this I <br /> section unlcss: <br /> (a) The person is insulated from the encrgiud part(gloves,with slceves if necessary,rated for Ihe i <br /> voltage involved are considered to be insulation of the person from the energizcd part on which <br /> work is perfomud);or <br /> � <br /> (b) 'Ihe energiud paR is insulated both from all othu conductivc objects at a dif(crent pmential and i <br /> from the person;or <br /> (c) TL•e person is insulated from all conductive objects at a potential differcnl from that of thc <br /> energizcd part. <br /> (8) Vchicular and mechanical equipmenl. <br /> (a) Any vehicle or mechanical equipment cap�ble o(tuviog pa�t�of i�s structure ekv�tal nwr <br /> enerRiud ovetfipo lines shall be opereted w ttut a doun�oe of 10 tt.u rtuioained. If M�e <br /> voltage u higha t6�n SOkV,the cleanoce�6a11 be ioaeased 0.4 inch for every 1 kV over th�t <br /> volhge. Nowever,under�ny of the follo�ving condi0ons,We ektwnce m�y be teduced: <br /> (i) If Uie vehide is in transil with its s�ructure lowered,the cl� aranec may be reduced w 4 ft. <br /> If Ihe volWgc is highcr than SOkV,the dcarance shall be incrcucd 0.4 inch for evcry <br /> IkV ovcr that voltagc, <br /> (ii) If insulating bartiers arc insWlled to provent contact with the lincs,and if thc bamcrs arc <br /> rated for Ihe vollagc of thc line bcing guarded and are not a part oC or an anachmcnt to <br /> du vchide or its raised swcturc,the dcarance may be reduced to a distance within thc <br /> dcsigned working dimrnsions of thc insulating barricr. <br /> (b) If thc cquipment is an acrial lifl insulated for thc voltagc involved,and if ttw work is perfonned by <br /> a qualified persou,the cleacance(between the uninsulated po:iion of the Ycrial lifl and the power <br /> linc)may bc reduced to thc disunce given in subsections(3)and(4)of this section. <br /> (c) Employees standing on the ground shall not contact the vehide or mec6anical equiprtxnt or eny <br /> of i�s attachmenls,unlcss: <br /> (i) 7'he employee is using protcetivc cquipment rated for the voltage;or <br /> (ii) Thc equipment is located so that no uninsulated part of its sWcturo(that portion of the <br /> structurc that providcs a conductivc path to employces on the ground)can come closcr to <br /> thc line than permitted in this scetion. <br /> (d) If any vehicle or mechanical cquipmcnt capable of having parts of its stmcturc cleva�ed near <br /> cncrgized oveficad lines is intcntionally groundcd,employees working on the ground ncar t6e <br /> poinl of grounding shall not stand at the grounding location whenever therc is a possibility of <br /> Part L,Pa�52 �/ <br /> . ovol �acu. 7�'� <br /> I <br />
