Vegetation Management Near Power Lines Risk Assessment

Product Overview

Identify and control organisational risks associated with Vegetation Management Near Power Lines through a structured, management‑level WHS Risk Management approach that focuses on planning, governance, systems and oversight. This Risk Assessment supports compliance with the Work Health and Safety Act and Regulations while helping to demonstrate Due Diligence and protect your business from operational and legal liability.

Hazards & Risks Covered

Hazard Risk Description
1. Governance, Legal Compliance & Duty of Care
  • • Failure to identify and comply with WHS Act 2011, WHS Regulation and relevant electrical safety legislation for work near power lines
  • • Lack of clear WHS policy framework for vegetation management around electrical assets
  • • Unclear allocation of PCBUs, officers and workers’ duties where multiple organisations (principal contractor, network operator, subcontractors) are involved
  • • Inadequate due diligence by officers in monitoring WHS performance and ensuring resources for safe work near live electrical installations
  • • No formal process to review changes in legislation, standards, Codes of Practice or network operator requirements
  • • Failure to define and document exclusion zones and ‘no‑go’ areas in line with jurisdictional electrical safety rules
2. Strategic Planning & Scope Definition for Vegetation Programs
  • • Poorly defined scope leading to work being undertaken in higher voltage or complex network areas without adequate controls
  • • Inadequate program-level risk assessment for seasonal conditions (e.g. bushfire season, storms, high winds) affecting vegetation and electrical risk
  • • Failure to prioritise high‑risk locations (e.g. near schools, hospitals, major roads, high‑voltage transmission lines) in maintenance cycles
  • • Insufficient coordination between asset owner, vegetation contractor and other PCBUs leading to overlapping works and conflicting controls
  • • Inadequate budget or time allocation driving unsafe shortcuts or rushed work near live power lines
3. Electrical Hazard Identification, Mapping & Access Authority
  • • Incomplete or outdated information about line voltages, circuit configurations and earthing systems
  • • Failure to identify all overhead and underground electrical assets, including service lines, stays and low‑visibility conductors
  • • No standardised process for obtaining and complying with network access permits, isolations, or switching schedules where required
  • • Inaccurate or absent plans showing exclusion zones and minimum approach distances for tree workers and equipment
  • • Assumption that lines are de‑energised without written confirmation from the network operator
  • • Insufficient communication of electrical hazard information to crews prior to mobilisation
4. Vegetation Risk Assessment, Clearance Standards & Arboricultural Practices
  • • Inconsistent assessment of tree species, growth rates, defects and fall characteristics near power lines
  • • Absence of standard clearance distances for different voltages and vegetation types, leading to inadequate or excessive trimming
  • • Use of unsuitable arboricultural techniques creating dropped limbs, regrowth issues and increased likelihood of future contact with conductors
  • • Lack of structured decision‑making for prune versus remove, particularly for high‑risk trees near critical electrical assets
  • • Failure to consider how wind, snow, storm events or tree failure could compromise power line clearances between maintenance cycles
5. Competency, Licensing & Authorisation of Workers and Supervisors
  • • Workers performing vegetation work near power lines without adequate electrical awareness or line clearance training
  • • Supervisors lacking specific competence to assess electrical, arboricultural and plant interaction risks
  • • Expired or invalid licences, authorisations or refresher training for EWP operators, chainsaw users and line‑clearance personnel
  • • Inadequate verification of subcontractor competence and currency of high risk work licences
  • • No system to confirm that only authorised persons work within defined approach distances to live conductors
6. Plant, Equipment & Tooling Management (Including EWPs, Chippers & Saws)
  • • Uncontrolled use of non‑insulated or unsuitable EWPs and plant near live overhead conductors
  • • Inadequate inspection, maintenance and testing of insulated booms, insulated poles, line‑clearance tools and electrical PPE
  • • Failure of mechanical systems (e.g. EWP, cranes, winches) causing contact with live lines or uncontrolled limb movement
  • • Use of incorrect or poorly maintained chainsaws, pole saws, rigging gear and chippers leading to kickback, dropped loads or projectile risks
  • • Lack of systems to prevent plant encroaching into exclusion zones (e.g. slewing, boom articulation, crane jibs)
7. Work Planning, Job Hazard Analysis & Change Management

  • • Failure to reassess risks when scope, weather or network operating conditions change during the job
  • • Inadequate consideration of limb size, direction of fall, potential for swing into conductors or induced contact
  • • No formal mechanism to pause or stop work when unexpected higher‑risk conditions arise (e.g. unrecorded services, unplanned switching)
  • • Inconsistent documentation and communication of job plans across multiple crews and contractors
8. Fatigue, Workload, Supervision & Competent Oversight
  • • Extended hours, high physical workload and repetitive trimming leading to fatigue‑related errors near live conductors
  • • Insufficient ratio of competent supervisors to work crews conducting complex limb removal around power lines
  • • Pressure to meet productivity targets resulting in shortcutting of safety systems and planning steps
