Additional risks to
consider

If working under live High Voltage can minimum safe
working distances be achieved?

Can live Low Voltage work be done safely, if not contact
supervisor

Can all live and earthed conductors be temporarily
insulated safely
To Prevent electrical hazards

Inspect all mats and covers for cleanliness, cracks or other
defects
If mats or covers are found to be defective remove from
service immediately

Inspect rubber gloves for holes and splits as per safety
training
If gloves deemed to be unserviceable after test DO NOT USE
To Ensure safety to workers

Ensure appropriate rescue kits are serviceable and all
contents lists are complete.
Working live from EWP

Ensure the EWP electrical test is current and in date


Preparation
Ensure emergency descent devices are functional and in a
serviceable condition
Working live from a ladder

Ensure the pole top rescue kit has in date size 11 gloves,
an orange rescue belt, cross arm straps and slings, and a
serviceable rescue rope

Ensure rescue kit is placed in an accessible position close
to work area
Working live on ground

Ensure Low Voltage release and rescue kit has a
serviceable rescue crook, a working shaker torch or
batteries for other torch, and in date size 11 rubber gloves
 Ensure rescue kit is placed in an accessible position close
to ladder
If any rescue kits are defective or missing equipment
REMOVE from service and do not proceed with live Low
Voltage work till a replacement kit is sourced.

Installing and
removing temporary
Low Voltage mats and
covers
Refer and follow SWI- 2 Installing and removal of Temporary
Low Voltage Insulators
ENSURE CORRECT P.P.E IS WORN AT ALL TIMES
All communication cables i.e. Optus and Foxtel are at
earthed potential and are to be treated as live conductors
To Prevent electrical hazards

Ensure that every conductor within your reach is insulated
in all directions from the point nearest your body. The
reach includes your extended reach with tools or
equipment you may be using.
Constantly inspect mats and covers to ensure that they have
not moved and are still sufficiently covering the Conductors

When working together confine the work to the same
phase or keep at least 500mm away from each other and
do not pass conductive material to one another

Beware of communications cable and catenary wires as
these conductors are to be treated as earth potential
cables.

When working on switchboards or live mains with exposed
metal work it may be necessary to temporarily insulate
earthed metal work and stand on an insulating mat

Insulated tools are not to be classed as insulated only
covered
