Hazards & Risks Covered

Hazard Risk Description
1. Strategic Planning, Design and Network Interface
  • • Inadequate early consultation with Distribution Network Service Provider (DNSP) leading to unsafe design interface with existing overhead power
  • • Design not compliant with AS/NZS 3000, AS/NZS 7000 or DNSP service & installation rules resulting in unsafe clearances or loading
  • • Underestimation of electrical load, fault levels or earthing requirements causing unsafe operation of street lighting and poles
  • • Failure to identify existing underground and overhead services during planning, increasing the risk of contact or service clashes
  • • Lack of consideration for future network augmentation causing overloaded infrastructure and unsafe backfeeds
  • • Insufficient consideration of public exposure (schools, playgrounds, high pedestrian areas) increasing risk profile but not reflected in design
  • • Inadequate incorporation of road authority requirements (e.g. sight lines, clear zones) creating vehicle strike and pole stability risks
2. Asset Information, Network Mapping and Service Location
  • • Incomplete or inaccurate asset registers and as-built drawings leading to unrecognised live conductors or cables
  • • Failure to update drawings after pole removals, relocations or street light installations resulting in future work on unknown live infrastructure
  • • Inadequate system for recording private vs DNSP-owned assets causing gaps in inspection and maintenance responsibilities
  • • Poor integration between GIS, work management and field mobility systems leading to out-of-date information in the field
  • • Lack of formal service location procedures prior to excavation near poles and footings
  • • Loss of historical information about older infrastructure (e.g. asbestos poles, legacy earthing systems) creating unmanaged health and electrical risks
3. Governance, Roles, Competency and Authorisations
  • • Unclear delineation between PCBU, principal contractor, DNSP and subcontractor responsibilities for electrical safety
  • • Workers performing work near or on overhead power without appropriate electrical authorisations or network access permits
  • • Inadequate competency standards for lineworkers, plant operators, riggers and supervisors involved with pole work and street lighting
  • • Lack of formal verification of licences, authorisations and refresher training prior to allocation to high-risk tasks
  • • Supervisors lacking specific competency in managing work near live overhead power lines and associated exclusion zones
  • • Insufficient resources allocated for competent electrical supervision and authorised persons on each site
4. Contractor and Subcontractor Management
  • • Engagement of contractors without proven experience in overhead power, pole installation/removal and street lighting projects
  • • Inadequate evaluation of contractor WHS management systems, particularly around electrical safety and plant operation
  • • Fragmented subcontracting chains leading to poor coordination and unmanaged interface risks between trades
  • • Contractual pressures encouraging unsafe shortcuts, such as working too close to live lines or bypassing isolation
  • • Lack of monitoring of contractor compliance with exclusion zones, permits and isolation procedures
5. Electrical Isolation, Access Authorities and Exclusion Zones
  • • Work undertaken within unsafe approach distances to live overhead conductors due to misunderstood or unenforced exclusion zones
  • • Absence of formal isolation and access authority processes when working on or near network assets
  • • Confusion regarding who controls the network isolation (DNSP vs private network) leading to unauthorised energisation
  • • Failure to verify de-energisation and earthing before pole removal, installation or temporary support activities
  • • Inadequate management of induced voltages, backfeed risks and auto-reclose features
  • • Poor communication of live line status and safe work boundaries to plant operators, riggers and ground staff
6. Plant, Equipment and Lifting Systems for Pole Works
  • • Use of non-rated or inadequately maintained cranes, EWPs, pole borers and lifting gear near live overhead infrastructure
  • • Plant selection not suited to ground conditions or clearances, creating collision or electrical arcing risks
  • • Failure of pole lifting or temporary support gear due to poor design, incompatibility or lack of engineering sign-off
  • • Inadequate systems preventing plant encroachment into electrical exclusion zones during slewing, elevating or travelling
