Working on Large Vehicles - Trailers Risk Assessment

Product Overview

Identify and control organisational risks associated with Working on Large Vehicles – Trailers through a structured, management-level Risk Assessment that supports planning, governance and system design. This document helps demonstrate Due Diligence under the WHS Act, reduces operational liability, and supports a defensible approach to WHS Risk Management across your trailer and heavy vehicle operations.

Risk Categories & Hazards Covered

This document assesses risks and outlines management controls for:

  • Governance, WHS Duties & Contractor Management: Assessment of PCBU obligations, officer due diligence, contractor selection, onboarding, and monitoring arrangements for work on and around large vehicles and trailers.
  • Fleet & Trailer Design, Procurement and Modification Control: Management of design standards, trailer specification, engineering verification, and change control for new builds, retrofits and modifications.
  • Site Layout, Traffic Management & Loading Area Design: Assessment of yard configuration, separation of people and plant, reversing and blind-spot risks, and controlled zones for loading, unloading and trailer work.
  • Working at Heights Management System (Trailers & Loads): Development of policies, hierarchy of control, and engineering solutions to eliminate or minimise fall risks when accessing trailers, loads and elevated work areas.
  • Access, Egress & Edge Protection on Trailers: Management of steps, ladders, platforms, handrails and non-slip surfaces to provide safe access and prevent falls from trailer decks and structures.
  • Load Design, Load Restraint & Tarping Systems: Assessment of load configuration, restraint equipment, mechanical tarping systems and procedures to control crush, shift, fall and over-centre risks.
  • Vehicle & Trailer Inspection, Maintenance & Integrity Management: Systems for scheduled inspections, defect reporting, maintenance prioritisation and asset lifecycle management to ensure trailers remain safe for use.
  • Competency, Training & Authorisation for Work on Large Vehicles: Definition of competency standards, licensing, verification of competency (VoC) and authorisation processes for drivers, loaders, mechanics and yard personnel.
  • Fatigue, Scheduling & Journey Management for Trailer Operations: Management of work hours, trip planning, rest breaks and rostering to minimise fatigue-related risks in loading, unloading and trailer preparation tasks.
  • PPE, Fall Arrest Systems & Equipment Management: Selection, issue, inspection and maintenance of PPE, harnesses, inertia reels and anchor points, including compliance with relevant Australian Standards.
  • Emergency Preparedness & Incident Management for Trailer Work: Planning for rescue from height, entrapment, vehicle movement incidents and load failures, including emergency equipment, drills and response protocols.
  • Communication, Consultation & Worker Engagement: Systems for toolbox talks, pre-starts, safety committees and consultation with drivers, loaders and contractors on trailer-related risks and controls.
  • Planning, Permits & Task Authorisation for Non-Routine Trailer Work: Use of permits, job planning and risk-based authorisation for complex, infrequent or high-risk activities on or around trailers.
  • Health Monitoring, Manual Handling & Musculoskeletal Risk Management: Assessment of physical demands, repetitive tasks, awkward postures and health surveillance for workers handling loads, restraints and tarps.
  • Assurance, Auditing & Continuous Improvement of Trailer WHS Systems: Implementation of inspections, audits, KPIs and review processes to verify control effectiveness and drive ongoing improvement in trailer safety management.

  • • Inadequate assessment of edge protection, anchor points, and compatibility of fall arrest equipment with trailers
  • • No permit or authorisation system for high‑risk trailer working at height activities
5. Access, Egress and Edge Protection on Trailers
  • • Workers climbing on trailer frames, wheels, drawbars or loads due to lack of safe access systems
  • • Unprotected edges on trailer decks and loads leading to falls from height
  • • Use of improvised access equipment (ladders, pallets, load components) not designed for the task
  • • Inadequate controls for accessing the top of loads (e.g. stacked pallets, pipe, machinery) on trailers
  • • Trailer movement or instability during access and egress activities
6. Load Design, Load Restraint and Tarping Systems
  • • Load configurations that require workers to climb on top of loads for placement of restraints, covers or tarps
  • • Inadequate load restraint system design leading to shifting loads, collapse or need for manual rework at heights
  • • Manual tarping and untarping methods requiring walking on unstable or uneven load surfaces
  • • Lack of standardisation of load restraint equipment and methods across the fleet
