Risk Assessment
Before starting to work near OHPLs you should always assess the risks. The following
points should be observed;
Know the risks of contacting OHPLs and the risk of flashover.
Find out the maximum height and maximum vertical reach of your machine.
Find out the location and route of all Power Lines within the work area.
Find out the operating voltage of all Power Lines within the work area.
Contact the local Distribution Network Operator (DNO) who will be able to advise you on
the operating voltage, safe minimum clearance distance for working, and additional
precautions required.
Never attempt to operate the machine in exclusion zones.
Always work with extreme caution and plan your work ahead to avoid high risk areas.
If doubt exists do not work in the area – never risk the safety of yourself or others.
Emergency Action for Accidents Involving Electricity
 Never touch an overhead line - even if it has been brought down by machinery, or has
fallen. Never assume lines are dead.
 When a machine is in contact with an overhead line, electrocution is possible if anyone
touches both the machine and the ground. Stay in the machine and lower any raised
parts in contact or drive the machine out of the lines if you can.
 If you need to get out to summon help or because of fire, jump out as far as you can
without touching any wires or the machine - keep upright and away.
 Get the electricity company to disconnect the supply. Even if the line appears dead, do
not touch it - automatic switching may reconnect the power.
