Hazards & Risks Covered

Hazard Risk Description
1. Procurement and Design Selection
  • • Selection of motor graders that are not fit for purpose or incompatible with site conditions (terrain, gradients, climate, material type)
  • • Lack of compliance with Australian Standards, manufacturer specifications and WHS legislation at point of purchase or hire
  • • Inadequate safety features (ROPS/FOPS, seat belts, emergency stops, reversing alarms, cameras, mirrors, access platforms and guarding)
  • • No consideration of whole-of-life safety costs leading to purchase of low‑cost, high‑risk plant
  • • Failure to obtain and control current operator manuals, service manuals and safety documentation
  • • Imported plant without proper verification of design, guarding and electrical/engineering compliance
2. Governance, WHS Duties and Contractor Management
  • • Unclear allocation of WHS responsibilities between PCBUs, senior management, supervisors, operators and maintenance personnel
  • • Multiple PCBUs (principal contractor, plant hire company, subcontractors) failing to consult, cooperate and coordinate as required under WHS Act 2011
  • • Lack of formal contractor management systems for hired graders and operators
  • • Inadequate monitoring of compliance with site rules, traffic management plans and safe work procedures
  • • Commercial pressures (time, cost, production targets) overriding safety expectations and leading to unsafe decision‑making
3. Operator Competency, Licensing and Training Systems
  • • Operators using motor graders without adequate verification of competency, experience or fitness for duty
  • • Reliance on informal or on‑the‑job training with no structured program or assessment
  • • No process to ensure operators are trained on the specific make/model and control layout of each grader
  • • Lack of refresher training, especially following incidents, near misses, changes in work environment or introduction of new technology
  • • Insufficient training on WHS obligations, site rules, isolation/lock‑out and emergency procedures
  • • Failure to manage language, literacy and numeracy (LLN) barriers leading to misunderstanding of controls and safety information
4. Policies, Procedures and Safe Systems of Work
  • • Absence of documented policies and procedures covering motor grader operations, leading to inconsistent and unsafe practices
  • • Procedures that are overly generic, complex, outdated or not aligned with current plant and site conditions
  • • Workers unaware of or unable to access relevant WHS documentation and safe systems of work
  • • Failure to integrate grader safety into broader site systems (traffic management, isolation, excavation, fatigue management)
  • • Lack of systematic review and continuous improvement of grader‑related procedures after changes, incidents or regulatory updates
5. Plant Registration, Documentation and Record Management
  • • Missing or incomplete records of ownership, modifications, inspections and maintenance history for graders
  • • Failure to register plant or notify the regulator where required under WHS legislation
  • • Lack of traceability for safety‑critical components (ROPS, FOPS, braking systems) and associated certifications
  • • Inability to demonstrate compliance to regulators, clients or auditors due to poor documentation
  • • Loss of critical information during handover, hire or sale of graders
6. Maintenance, Inspection and Defect Management Systems
  • • Inadequate preventative maintenance leading to brake failure, steering failure, hydraulic failure or structural collapse
  • • Uncontrolled defects and delayed repairs due to lack of an effective reporting and tagging system
  • • Use of graders that are overdue for service or critical inspections
  • • Maintenance activities carried out by unqualified personnel or without reference to OEM specifications
  • • Lack of systematic pre‑start and post‑use inspection processes and records
  • • Failure to manage safety risks associated with attachments, blades, rippers and ancillary equipment
7. Site Planning, Traffic Management and Journey Management
  • • Uncontrolled interaction between graders and light vehicles, pedestrians, other mobile plant and the public
  • • Poorly planned haul routes, work zones and turning areas leading to collisions, rollovers or contact with structures and services
  • • Operation of graders on unsuitable ground conditions (soft edges, steep batters, unstable fill, underground voids)
  • • No formal journey management or task planning for remote or extended operations
