Power pole temporary support and stay-rope installation is a high-risk emergency intervention undertaken when distribution or consumer mains poles lean, fracture at the butt, or suffer impact damage from vehicles, storms, or ground subsidence. The work involves authorised network access, selection of compatible propping equipment, rigging of temporary stays, and management of live overhead conductors that may be displaced from their design envelope. Under WHS Regulation 2025 section 291, any work on or near energised overhead powerlines is classified as High Risk Construction Work, mandating a Safe Work Method Statement prepared before the task commences and signed by every worker on the crew. The combination of unstable structural loading, live electrical apparatus, public exposure on roadways, and dynamic ground conditions creates a hazard profile that cannot be managed through generic procedures. A task-specific SWMS is the legal mechanism that consolidates network operator permits, exclusion zones under AS 5804, traffic management under AS 1742.3, and the rigging engineering required to stabilise the pole without precipitating collapse.
Hazards identified
7 hazards covered, sorted by priority.
Fatal electrocution, arc-flash burns to face and hands, and induced current injury to crew at ground level
Crush injuries, fatality from falling pole and hardware, and secondary electrical contact when conductors hit ground
Cardiac arrest and severe burns from voltage gradient transfer through the ground to workers and bystanders
Multiple trauma fatalities and serious injury when traffic management is inadequate or breached by motorists
Electrocution of operator, equipment damage, and network fault propagation triggering wider outage and arc events
Whip-back lacerations, crush injuries, and uncontrolled pole movement endangering ground workers and traffic
Acute lumbar injury, soft-tissue strain, and slip-trip-fall incidents on sloped or saturated ground
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Where the pole is beyond economic stabilisation, request network operator de-energisation and full replacement rather than temporary propping to remove the live conductor hazard entirely.
- 2Elimination — Eliminate worker presence in the fall arc by using remote-tensioned stay winches operated from outside the 1.5x pole-height collapse exclusion zone during all load application.
- 3Substitution — Substitute timber props with engineered hydraulic pole-prop systems rated and certified to AS 4991 lifting load standards, providing measurable load feedback during tensioning.
- 4Substitution — Substitute manual ground anchors with helical screw anchors driven by powered installer, reducing crew exposure time at the base of an unstable pole.
- 5Engineering — Establish no-go exclusion zones under AS 5804.1 matched to the network voltage, with insulated barriers and earthed conductive screens between work area and live phases.
- 6Engineering — Deploy AS 1742.3 compliant traffic management with physical lane closure, water-filled barriers, and approved arrow boards before any crew member enters the carriageway.
- 7Administrative — Obtain network operator access permit and switching schedule before commencement; verify isolation or live-line work category and brief the crew using this SWMS at pre-start.
- 8Administrative — Appoint a dedicated safety observer with an emergency stop authority, radio link to crane operator, and rescue plan rehearsed before any load is taken on the props.
- 9Administrative — Restrict task to authorised overhead linesworkers holding current ESI competencies, with weather stand-down triggers at wind speeds above 35 km/h or active lightning within 10 km.
- 10PPE — Workers wear arc-rated clothing to AS/NZS 4836, Class 00 or higher insulated gloves matched to voltage, hard hat with chin strap, eye protection, and dielectric safety footwear.
Applicable Codes of Practice
Defines minimum approach distances and exclusion zones around energised conductors that govern propping equipment placement and crew positioning throughout the task.
Sets isolation, testing, and PPE obligations for consumer mains work, including arc-rated clothing selection during temporary support of low-voltage poles.
Mandates traffic management plan, signage, and barrier configuration when pole stabilisation work occupies or adjoins trafficked carriageways or footpaths.
Triggers PCBU duty to identify electrical risks, implement hierarchy controls, and consult network operator before any work near overhead powerlines proceeds.
High-Risk Construction Work triggered
Temporary support is performed on poles carrying energised distribution or consumer mains conductors, placing crew within reach of live electrical apparatus throughout the propping sequence.
PCBU must prepare and consult workers on this SWMS before work starts and retain it for two years, or longer if a notifiable incident occurs; penalties for non-compliance are substantial and indexed, with the current maximum following the prevailing WHS schedule.
Who this is for

Worked example
At a suburban arterial road intersection, a four-wheel drive has struck a 12-metre wood distribution pole carrying 11 kV mains and low-voltage consumer service, leaving it leaning approximately 15 degrees toward an adjacent footpath. The crew leader retrieves the Power Pole Temporary Support SWMS at the truck and runs the pre-start brief tailgate. Each linesworker reads the hazard register, with specific attention drawn to the displaced conductor clearance and the step-potential zone around the cracked butt. The leader confirms the network operator switching permit number, marks the 1.5x pole-height collapse exclusion zone with bollards, and deploys the AS 1742.3 traffic plan closing the kerbside lane. A helical screw anchor is installed remotely, and the hydraulic pole-prop is positioned using the EWP — the operator references the SWMS exclusion zone diagram to confirm the bucket maintains 1.2 metres from the nearest 11 kV phase. Every crew member signs the SWMS sign-on register, including the traffic controller. Midway through stay tensioning, wind gusts exceed the 35 km/h stand-down trigger documented in the controls. The safety observer halts work, the crew retreats to the exclusion zone boundary, and the SWMS is annotated with the stand-down decision. When conditions ease, work resumes under the same controls with a fresh dynamic risk check recorded on the document.

Frequently asked questions
Is emergency pole propping high risk construction work?
Yes. Temporary support is carried out on poles carrying energised distribution or consumer mains, placing the crew near live electrical apparatus for the whole propping sequence, which is a s291 category of high risk construction work. A SWMS must be prepared and signed by every worker before the task starts under s299, and retained for two years or longer if a notifiable incident occurs. The urgency of a storm or vehicle-strike callout does not suspend that duty — it is the reason the document exists in a pre-prepared, editable form rather than being written on the roadside.
Does this cover step and touch potential around a leaning pole?
Yes, and it is treated as a hazard to bystanders as much as to the crew. A pole with cracked insulators, a compromised butt or damaged earthing can put a voltage gradient into the ground around it, so a person can be injured without touching anything. The controls establish no-go exclusion zones matched to the network voltage under AS 5804.1, with insulated barriers and earthed conductive screens between the work area and the live phases, and the network operator access permit and switching schedule sighted before anyone approaches. The displaced conductor clearance is checked separately, because a leaning pole moves phases out of their design envelope.
How far back does the crew stand while the stay is tensioned?
Outside a collapse exclusion zone set at 1.5 times the pole height, with load applied by remote-tensioned stay winches so no one stands in the fall arc. That matters because the pole is already compromised — a fractured butt or cracked cross-arm can let go under the very load intended to stabilise it, bringing conductors to ground. Anchors are helical screw type driven by a powered installer rather than hand-set, which cuts crew exposure time at the base, and props are engineered hydraulic units certified to AS 4991 that give measurable load feedback instead of timber baulks assessed by eye.
When must the crew stand down?
At wind gusts above 35 km/h or active lightning within 10 km, and those are documented triggers with a named person holding stop authority — a dedicated safety observer with an emergency stop call and a radio link to the crane operator. The worked example runs that sequence: gusts exceed the trigger mid-tension, the observer halts, the crew retreats to the exclusion zone boundary, the stand-down is annotated on the document, and work resumes only after a fresh dynamic risk check is recorded. A rescue plan is rehearsed before any load goes onto the props, not improvised afterwards.
When should we prop and when should we replace the pole?
The document puts elimination first: where a pole is beyond economic stabilisation, request network operator de-energisation and full replacement rather than propping, which removes the live conductor hazard instead of managing it. Propping is the right call for a pole that is structurally recoverable and needs to be held while the network is restored. The task is restricted to authorised overhead linesworkers holding current ESI competencies, and where the work occupies or adjoins a carriageway, a compliant traffic plan with physical lane closure, water-filled barriers and approved arrow boards goes in before any crew member steps out.
