Wood Chipper Risk Assessment

Product Overview

Identify and control organisational risks associated with wood chipper procurement, planning, operation and oversight using this management‑level Wood Chipper Risk Assessment. This document supports executive Due Diligence, strengthens WHS Risk Management systems, and helps demonstrate compliance with the WHS Act while reducing operational liability exposure.

Risk Categories & Hazards Covered

This document assesses risks and outlines management controls for:

  • Procurement, Design Selection & Guarding Compliance: Assessment of pre‑purchase criteria, guarding standards, safety features, and supplier documentation to ensure wood chippers meet Australian WHS and plant safety requirements.
  • Site Planning, Layout & Public Interface Management: Management of work area set‑up, exclusion zones, pedestrian and public separation, signage and traffic interface to minimise exposure to chipping operations.
  • Organisational Governance, WHS Responsibilities & Consultation: Clarification of PCBU, officer and worker duties, consultation arrangements, and safety leadership structures for wood chipper operations.
  • Operator Competency, Training & Authorisation: Protocols for competency assessment, VOC, licensing requirements, refresher training and formal authorisation to operate wood chippers.
  • Safe Operating Procedures & Work Method Systems: Development and control of documented procedures, supervision expectations, start‑up/shut‑down systems and integration with existing WHS management processes.
  • Maintenance, Inspection & Pre‑Start Systems: Scheduled servicing, pre‑start checklists, defect reporting, and management of plant condition to prevent mechanical failure and unsafe operation.
  • Isolation, Lock‑Out/Tag‑Out & Jam Clearing Management: Systems for energy isolation, guarding removal controls, jam clearing protocols and verification of zero‑energy state before intervention.
  • Noise, Vibration, Dust & Environmental Exposure Controls: Assessment of exposure levels, engineering and administrative controls, monitoring requirements and environmental impact considerations.
  • Ergonomics, Manual Handling & Material Flow Management: Management of feed practices, push/pull forces, repetitive tasks and work area design to reduce musculoskeletal injury risk.
  • Weather, Terrain & Remote/Isolated Work Management: Controls for heat, cold, wind, unstable ground, slopes and communication systems for lone or remote wood chipper operations.
  • Roadside, Mobile & Traffic‑Adjacent Operations: Traffic management planning, vehicle positioning, work near roads, and coordination with local authorities and principal contractors.
  • Contractor, Labour Hire & Subcontractor Management: Pre‑qualification, information exchange, supervision, and verification of contractor safety systems when using wood chippers.
  • Emergency Preparedness, First Aid & Incident Management: Planning for entanglement, ejection, fire, medical emergencies, rescue arrangements and post‑incident investigation processes.
  • PPE Programs, Fit, Selection & Compliance Monitoring: Selection of appropriate PPE for noise, eye, hand and limb protection, fit‑testing, training and enforcement of PPE use.
  • Documentation, Records & Continuous Improvement: Management of policies, risk registers, training records, inspections, audits and review processes to demonstrate ongoing WHS due diligence.

Who is this for?

This Risk Assessment is designed for Business Owners, General Managers, Safety Managers and Supervisors responsible for planning, approving and overseeing wood chipper operations within their organisation.

Hazards & Risks Covered

Hazard Risk Description
1. Procurement, Design Selection and Guarding Compliance
  • • Purchase of wood chipper that is not compliant with Australian Standards or WHS Act 2011 duties for safe plant
  • • Inadequate fixed guarding around in‑feed chute, discharge areas, belts, pulleys and rotating knives creating entanglement and amputation risks
  • • Lack of emergency stop devices or poor location/accessibility of emergency stops
  • • Insufficient consideration of noise, vibration and dust emissions at procurement stage
  • • Failure to specify safety interlocks on covers and access panels leading to exposure to moving parts during maintenance
  • • Inadequate documentation from supplier (operator manual, service manual, safety instructions, risk assessment)
  • • Selection of plant not fit for intended use (e.g. feed capacity, mobility, guarding design not suited to operational environment)
2. Site Planning, Layout and Public Interface Management
  • • Inadequate separation between wood chipper operations and public access areas leading to struck‑by or contact incidents
  • • Poor traffic management resulting in collisions between chipper, trucks, plant and pedestrians
  • • Insufficient exclusion zones around in‑feed and discharge areas causing exposure to ejected material and noise
  • • Unsuitable set‑up locations near overhead powerlines, underground services or unstable ground
  • • Lack of signage and barriers leading to unauthorised entry into operational areas
  • • Noise and dust impacts on neighbouring properties leading to complaints and regulatory action
3. Organisational Governance, WHS Responsibilities and Consultation
  • • Unclear WHS roles and responsibilities relating to wood chipper ownership, operation and maintenance
  • • Lack of management oversight of plant safety leading to uncontrolled risk escalation
  • • Inadequate consultation with workers and Health and Safety Representatives on plant risks and control measures
  • • Poor integration of wood chipper risks into the organisation’s WHS management system
  • • Failure to coordinate WHS responsibilities when multiple PCBUs share a worksite (e.g. contractors, principal contractors, local councils)
4. Operator Competency, Training and Authorisation
  • • Inadequate training in the specific make and model of wood chipper leading to unsafe use
  • • Lack of competency assessment and verification before allowing unsupervised operation
  • • Insufficient understanding of emergency procedures, isolation points and emergency stops
  • • No system to maintain training currency for infrequently used chippers
  • • Language, literacy or communication barriers resulting in misunderstanding of procedures and signage
  • • Use of labour hire or casual workers without appropriate induction and competency checks
5. Safe Operating Procedures and Work Method Systems
  • • Absence of documented safe operating procedures (SOPs) for wood chipper use
  • • Use of inconsistent or informal work methods across different crews and sites
  • • Failure to incorporate manufacturer’s operating limits and warnings into local procedures
  • • Unsafe practices becoming normalised due to time pressure or productivity targets
  • • Lack of clear rules for working near the in‑feed chute, discharge areas and moving plant
6. Maintenance, Inspection and Pre‑Start Systems
  • • Inadequate preventative maintenance leading to mechanical failure, unplanned downtime and injury
  • • Failure of guards, interlocks, knives, belts or hydraulic systems due to lack of inspection
  • • Use of damaged or missing guards and safety devices because defects are not reported or rectified
  • • Uncontrolled changes or repairs by unqualified personnel creating new hazards
  • • Lack of documented maintenance history impacting the ability to identify patterns of failure
7. Isolation, Lock‑Out/Tag‑Out and Jam Clearing Management
  • • Exposure to rotating cutters and moving parts during clearing of blockages or jams
  • • Attempting to clear jams without isolating and verifying zero energy state
  • • Uncontrolled release of stored energy in hydraulic, mechanical or electrical systems
