Work Near Overhead Power Lines Risk Assessment

Product Overview

Identify and control organisational risks associated with working near overhead power lines through a structured, management-level WHS Risk Management approach that addresses governance, planning, systems and ongoing oversight. This Risk Assessment supports compliance with the WHS Act, reduces operational liability, and demonstrates clear due diligence in the prevention of electrical contact incidents.

Risk Categories & Hazards Covered

This document assesses risks and outlines management controls for:

  • Governance, Legal Compliance and Electrical Consultation: Assessment of statutory duties, consultation with electricity supply authorities, and the integration of specialist electrical advice into organisational policies and decision-making.
  • Planning, Design and Engineering Controls: Management of design-stage decisions, exclusion zones, de-energisation options, physical barriers, and engineered control measures to minimise the risk of contact with overhead lines.
  • Procurement of Plant, Equipment and Services: Evaluation of plant selection, insulating equipment, spotters, and external services to ensure all procured items and contractors are suitable and compliant for work near overhead power lines.
  • Competency, Training and Awareness: Assessment of competency requirements, licence and authorisation checks, and targeted training programs to ensure workers, supervisors and spotters understand electrical hazards and control measures.
  • Site Layout, Signage and Physical Delineation: Management of site planning, access routes, no-go zones, warning devices, and signage to clearly delineate safe working distances and restrict encroachment into hazardous areas.
  • Systems of Work, Permits and Supervision: Development of documented procedures, permit-to-work systems, pre-start checks, and supervisory arrangements to control how work near overhead power lines is authorised and conducted.
  • Contractor and Subcontractor Management: Protocols for pre-qualification, scope definition, information sharing, and oversight of contractors to ensure consistent application of electrical safety controls across all parties.
  • Monitoring, Inspection and Maintenance of Controls: Systems for scheduled inspections, testing and verification of barriers, warning devices, plant and protective equipment to ensure controls remain effective over time.
  • Incident Reporting, Investigation and Continuous Improvement: Frameworks for reporting near misses and incidents, conducting root cause analyses, and implementing corrective actions to strengthen organisational electrical safety performance.
  • Emergency Preparedness and Response for Electrical Incidents: Planning for rescue, isolation, first aid (including electric shock response), communication protocols and liaison with emergency services in the event of electrical contact or arcing.

Who is this for?

This Risk Assessment is designed for Business Owners, Principal Contractors, Project Managers and Safety Managers responsible for planning, approving and overseeing work near overhead power lines across construction, civil, utilities and maintenance operations.

Hazards & Risks Covered

Hazard Risk Description
1. Governance, Legal Compliance and Electrical Consultation
  • • Failure to identify and comply with WHS Act 2011, WHS Regulations 2011 and relevant electrical safety legislation and codes of practice for work near overhead power lines
  • • Absence of a formal process to determine whether overhead lines are energised, voltage level, owner and exclusion zones
  • • Lack of documented consultation with the electricity supply authority and/or asset owner before planning work near lines
  • • No defined organisational policy on minimum approach distances and when power must be isolated, re-routed or mechanically protected
  • • Fragmented responsibilities between PCBU, principal contractor, subcontractors and labour hire without clear allocation of WHS duties for electrical risks
  • • Inadequate system to ensure updates when standards, codes, network operator requirements or legislation change
2. Planning, Design and Engineering Controls
  • • Project planning that does not consider the location and voltage of overhead power lines during concept and design stages
  • • Reliance on informal site knowledge rather than survey, plans or as‑built information to locate overhead assets
  • • Failure to eliminate or minimise exposure by redesigning work methods, equipment type, access routes or temporary works layouts
  • • Inadequate engineering assessment of plant reach, load swing, crane radii, tip heights and potential for inadvertent encroachment into exclusion zones
  • • Poor integration of overhead power line constraints into traffic management, delivery scheduling and material storage layouts
  • • Temporary works or scaffolding design that does not account for conductive components, potential line sag, wind effects or future modifications
  • • No requirement to reassess risks when site conditions change (e.g. new lines installed, line sag due to heat, re‑routing, construction staging changes)
3. Procurement of Plant, Equipment and Services
  • • Procurement of unsuitable plant with excessive reach, boom length or uncontrolled articulation for work near overhead lines
  • • Hiring subcontractors and crane/plant suppliers without verifying their systems for working near power lines and compliance with relevant standards
  • • Lack of specification for non‑conductive or insulated tools, ladders and equipment in environments with overhead electrical hazards
  • • Inadequate consideration of safety features such as slew/height limiting devices, proximity warning systems and interlocks in procurement decisions
  • • Absence of contractual requirements for suppliers to provide documentation such as lift studies, engineering certifications and maintenance records relevant to overhead line risks
  • • Cost‑driven purchasing that does not account for the additional risk control features necessary when working in proximity to high voltage infrastructure
4. Competency, Training and Awareness
  • • Inadequate management understanding of legal duties and consequences associated with electrical risks and overhead power lines
  • • Plant operators, doggers, riggers, spotters and supervisors lacking competency in recognising overhead electrical hazards and exclusion zones
  • • New starters, labour hire workers and visitors not informed about overhead lines and site‑specific electrical controls
  • • No formal training on emergency response to electrical incidents, including step‑potential risks and safe evacuation techniques
  • • Over‑reliance on spotters who may be untrained, distracted or unsure of their authority to stop work
  • • Training materials that are generic, out‑of‑date or not contextualised to the specific site conditions and voltage levels
5. Site Layout, Signage and Physical Delineation
  • • Overhead power lines not clearly identified or marked on site, leading to normalisation and complacency
  • • Inadequate or inconsistent signage warning of overhead electrical hazards at site access points and critical work areas
  • • Lack of physical barriers, line markings or exclusion zone demarcation to prevent plant encroachment
  • • Poor lighting during early morning, evening or night work that obscures visibility of lines and signage
  • • Movement of materials, scaffolds or temporary structures into previously controlled zones without updating markings and signage
  • • Site rearrangements (e.g. relocation of amenities or storage areas) gradually encroaching on previously defined no‑go areas
6. Systems of Work, Permits and Supervision
  • • Absence of a formalised permit‑to‑work or authorisation system for work near overhead power lines
  • • Inconsistent or informal work planning that relies on verbal briefings rather than documented risk assessments and method controls
  • • Insufficient supervision of high‑risk activities near lines, particularly during critical tasks such as craning, concrete pumping or steel erection
  • • Lack of clear criteria for when work must cease due to environmental conditions such as high winds, poor visibility or storms
  • • Fragmented coordination between multiple contractors working simultaneously near overhead infrastructure
  • • Failure to review and update risk assessments and work methods when scope, equipment or conditions change
7. Contractor and Subcontractor Management
  • • Engagement of contractors who lack robust systems for managing overhead electrical risks
  • • Poor communication of site‑specific overhead power line hazards and controls to subcontractors and labour hire personnel
  • • Inconsistent standards between principal contractor and subcontractors regarding exclusion zones, spotter use and permit systems
  • • Commercial pressures on subcontractors leading to shortcuts or non‑compliance with agreed controls
  • • Insufficient monitoring of contractor performance and reliance on self‑regulation for high‑risk electrical work
  • • Ambiguity over who holds primary responsibility for coordinating control measures when multiple PCBUs share the same work area
8. Monitoring, Inspection, and Maintenance of Controls
  • • Degradation or failure of control measures over time, such as damaged signage, faded markings or malfunctioning plant safety systems
  • • Infrequent or informal inspections leading to undetected encroachment risks or changed line conditions
  • • Failure to identify environmental changes affecting line clearance, such as ground level changes, stockpiling or vegetation growth
  • • Lack of verification that engineering controls (limiters, alarms, interlocks) are operational and correctly set for the site conditions
  • • Inadequate maintenance of plant used near overhead lines, increasing likelihood of unplanned movements or loss of control
  • • No systematic review to confirm that de‑energisation, relocation or shielding arrangements requested from the network operator remain in place and effective
9. Incident Reporting, Investigation and Continuous Improvement
  • • Under‑reporting of near misses and minor contact incidents with overhead lines, leading to missed learning opportunities
  • • Superficial investigations that focus on individual errors rather than systemic or organisational causes
  • • Lack of structured process to incorporate investigation findings into procedures, training and design standards
  • • Failure to share relevant findings across multiple projects or business units where similar overhead line exposures exist
  • • Management not tracking leading indicators related to electrical risk (e.g. near misses, permit breaches) and therefore not acting early
  • • Workers perceiving negative consequences for reporting overhead line hazards or near misses, discouraging open communication
10. Emergency Preparedness and Response for Electrical Incidents
  • • Workers and supervisors not knowing how to respond safely to contact with overhead power lines, increasing risk of secondary injuries or fatalities
  • • Emergency plans that do not address specific hazards of electrical incidents, such as step‑potential and delayed line isolation
  • • Lack of coordination with the electricity network operator and emergency services regarding site access and isolation procedures
  • • Inadequate availability or maintenance of emergency equipment (e.g. communication devices, rescue kits, first aid supplies) appropriate to electrical incidents
  • • Confusion over who has authority to stop work and initiate emergency response when overhead line contact or arcing is suspected
  • • No post‑incident process to verify structural and electrical integrity of affected plant, structures or lines before resuming work
