Overhead Power Lines
It cannot be stressed enough the dangers involved when working in the vicinity of
Overhead Power Lines (OHPLs). Some of our machines are capable of reach in
excess of 8 metres
(26’);
they have the potential to well exceed, by possibly 3 metres
(9’ 9”),
the lowest legal minimum height of 5.2 metres from the ground for 11,000 and
33,000 volt power lines.
Remember electrocution can occur without actually coming into contact with a power
line as electricity can ‘flashover’ when machinery gets close to it.
WARNING: All operators must read the following information and be
aware of the risks and dangers involved when working in the vicinity
of Overhead Power Lines (OHPLs).
Wherever possible the safest option is always to avoid working in areas close to
OHPLs.
Where unavoidable, all operators must perform a risk assessment and implement a
safe procedure and system of work
–
see following page for details.
All operators should perform a risk assessment before operating the machine within
10m horizontal distance of any OHPLs.
