Traffic Control Setup Signage and Barricades Risk Assessment

Product Overview

Identify and control organisational risks associated with Traffic Control Setup, Signage and Barricades at the planning, governance and systems level using this comprehensive management-focused Risk Assessment. This document supports Due Diligence under the WHS Act, helping you demonstrate robust WHS Risk Management and reduce organisational and operational liability.

Risk Categories & Hazards Covered

This document assesses risks and outlines management controls for:

  • WHS Management, Governance and Legal Compliance: Assessment of executive due diligence, safety leadership, policy frameworks and alignment with statutory obligations for traffic control operations.
  • Planning and Design of Traffic Management Systems: Management of planning processes, traffic guidance schemes, layout design, and integration with road authority requirements before works commence.
  • Risk Assessment and Change Management Processes: Protocols for formal risk assessments, change control, variation approvals and review triggers for altered traffic conditions or work stages.
  • Worker Competency, Licensing and Training Systems: Oversight of competency matrices, traffic controller licensing, refresher training and verification of competency for all personnel involved in setup and supervision.
  • Procurement and Equipment Standards for Signage and Barriers: Controls for selecting, purchasing and standardising compliant signs, cones, bollards, barriers and devices in line with relevant road and WHS standards.
  • Inspection, Maintenance and Asset Management of Traffic Control Devices: Systems for pre-use inspection, scheduled maintenance, defect reporting and lifecycle management of signage, barricades and associated equipment.
  • Site Access, Isolation Zones and Public Interface Management: Management of vehicle and pedestrian access, exclusion zones, interface with live traffic, and protection of the public and third parties.
  • Night Works, Lighting and Visibility Management: Assessment of illumination levels, retro-reflectivity, visibility of workers and devices, and additional controls for low-light and adverse weather conditions.
  • Communication, Sign-Off and Verification of Setup: Protocols for pre-start briefings, setup checklists, sign-off processes and verification that traffic control layouts match approved plans.
  • Monitoring, Supervision and Field Assurance: Systems for on-site supervision, periodic inspections, audits and real-time monitoring to ensure ongoing effectiveness of traffic control measures.
  • Emergency Preparedness and Incident Response for Traffic Setups: Planning for breakdowns, crashes, near misses and other emergencies, including escalation pathways and coordination with emergency services.
  • Fatigue, Work Scheduling and Resourcing for Traffic Control: Management of shift patterns, extended hours, night works, staffing levels and fatigue risk for traffic controllers and supervisors.
  • Contractor, Traffic Control Provider and Stakeholder Management: Governance of third-party traffic control providers, contractual requirements, prequalification and coordination with clients, councils and road authorities.
  • Information, Documentation and Record Management: Control of plans, permits, approvals, risk assessments, training records and setup verification documents to support legal defensibility.
  • Continuous Improvement, Consultation and Learning from Events: Systems for consultation with workers, review of incidents and feedback, and implementation of corrective actions to improve future traffic control setups.
