Working Near Overhead Power Lines (No Go Zones) Risk Assessment

Product Overview

Identify and control organisational risks associated with Working Near Overhead Power Lines (No Go Zones) through a structured, management-level WHS Risk Management approach that supports planning, policy, training and engineering controls. This Risk Assessment helps demonstrate Due Diligence under the WHS Act, reducing organisational exposure to prosecution, enforceable undertakings and operational liability.

Risk Categories & Hazards Covered

This document assesses risks and outlines management controls for:

  • Organisational WHS Governance & Legal Compliance: Assessment of executive due diligence, policies, procedures and verification processes relating to work near overhead power lines and No Go Zones.
  • Planning, Design & Engineering of Work Near Power Lines: Management of design-stage decisions, engineering solutions, route selection and constructability reviews to eliminate or minimise electrical contact risks.
  • Site Identification, Surveying & Services Location: Protocols for identifying overhead assets, confirming voltage and ownership, and integrating survey and Dial Before You Dig information into work planning.
  • No Go Zone Rules, Procedures & Documentation: Development and control of documented No Go Zone rules, permits, authority-to-work systems and task-specific risk assessments for proximity to live conductors.
  • Management of Contractors, Subcontractors & Utility Providers: Oversight of third-party engagement, prequalification, competency verification and coordination with electricity supply authorities and network providers.
  • Plant, Equipment Selection & Engineering Controls: Assessment of suitability and compliance of EWP, cranes, excavators and other plant, including use of insulating devices, slew and height limiters, and physical barriers.
  • Operator Competency, Licensing & Training: Verification of licences, high-risk work authorisations, refresher training and specific No Go Zone awareness for operators, spotters and supervisors.
  • Site Induction, Communication & Information Sharing: Systems for site-specific inductions, communication of power line locations, voltage, safe approach distances and emergency procedures to all workers and visitors.
  • Physical Separation, Exclusion Zones & Signage: Establishment and maintenance of compliant approach distances, barricades, flagging, warning signs and traffic management to prevent encroachment into No Go Zones.
  • Spotters, Supervision & Work Monitoring: Requirements for trained safety observers, supervision levels, real-time monitoring of plant movements and enforcement of stop-work authority.
  • Change Management, Non‑Routine & Emergency Work: Controls for variations, after-hours works, breakdown response and non-standard tasks that may alter risk profiles near overhead power lines.
  • Environmental Conditions & Work Scheduling: Management of wind, rain, poor visibility, lightning, temperature and other environmental factors affecting electrical arcing, line sway and safe clearances.
  • Emergency Preparedness, Response & Recovery: Planning for electrical contact or arcing incidents, including rescue procedures, isolation, first aid for electric shock and post-incident recovery and investigation.
  • Inspection, Maintenance & Verification of Controls: Scheduled inspection of plant, insulating equipment, barriers and signage, plus audits and reviews to confirm that No Go Zone controls remain effective.
  • Fatigue, Human Factors & Behavioural Safety: Consideration of fatigue, distraction, production pressure, risk perception and behavioural programs to support safe decision-making near power lines.

  • • Gaps between principal contractor and subcontractor procedures for electrical proximity
  • • Unclear coordination with electricity network operators for isolations, shutdowns or line relocations
  • • Inadequate verification of licences, high‑risk work authorisations and competency of external operators (e.g. crane crews, EWP operators)
