Access <strong>for</strong> Work on or Near High Voltage ElectricalApparatus• The <strong>work</strong> shall be per<strong>for</strong>med in accordancewith Organisational Procedures.9.6.3 Live Work9.6.3.1 Insulating Stick WorkAn Authorised Live-HV Worker may access livehigh voltage conductors using insulating sticks andat the special safe approach distances asdetermined through reference to Clause 6.2.2.9.6.3.2 Glove and Barrier WorkAn Authorised Live-HV Worker may make insulatedcontact with live high voltage conductors up to33kV when fully insulated from earth and otherphases using approved and tested personalprotective equipment and insulating devices.9.6.3.3 Bare Hand WorkAn Authorised Live-HV Worker may make barehand contact with live high voltage conductors <strong>of</strong>220kV and above provided that they are fullyinsulated from earth and other conductors atdifferent potentials by means <strong>of</strong> air gapsappropriate to the voltage <strong>of</strong> the conductors andthe precautions applied.Page 98 <strong>of</strong> 148 Blue Book – December 2005
Access <strong>for</strong> Work on or Near High Voltage ElectricalApparatus9.7 PREPARING HIGH VOLTAGEELECTRICAL APPARATUS FOR ACCESS9.7.1 Isolation and EarthingHigh voltage <strong>electrical</strong> apparatus should not beregarded as being safe <strong>for</strong> the issue <strong>of</strong> an <strong>electrical</strong>access permit until it has been isolated andearthed.Consideration shall be given to the isolation <strong>of</strong>sources <strong>of</strong> supply from low voltage or secondarycircuits.Organisational procedures shall ensure theintegrity <strong>of</strong> the isolation is maintained duringcurrency <strong>of</strong> the <strong>electrical</strong> access permit.Isolation <strong>for</strong> access shall either be visible, or anapproved means used to confirm that the <strong>electrical</strong>apparatus is de-energised.Note: Such isolation may not eliminate the effects<strong>of</strong> <strong>electrical</strong> or magnetic induction.Earths shall be applied as described in Clause 8.2.If earthing is not practicable other appropriateprecautions shall be taken and the authorised<strong>electrical</strong> operator shall advise the recipient inBlue Book – December 2005 Page 99 <strong>of</strong> 148
