OPERATING NEAR TO POWER LINES
It is essential that anyone working
near
to live electrical conductors is fully
conversant with the appropriate national and local regulation.
NOTE
: The VM135 Platform is '
not insulated
' and should
not
therefore be used for live
line working.
The
minimum
safe working distance from live overhead power lines for work
platforms is 15m from steel towers and 9m from concrete, steel and wooden
poles (BS8460:2005). Measurement must be taken at ground level with the
booms pointing towards the lines.
If work is to be carried out at LESS than the stated working distance, the
electricity supply MUST be switched off and a written PERMIT TO WORK must
be obtained from a responsible person representing the authority operating the
power lines.
NOTE
: See Health and Safety Executive Guidance Note G.S.G. entitled
'
Avoidance of Danger from Overhead Electric Lines
' for more detailed
information.
