Plastic Fabrication Risk Assessment

Product Overview

Identify and control organisational risks associated with Plastic Fabrication through a structured, management-level WHS Risk Management approach that focuses on planning, systems and governance rather than task-by-task procedures. This Risk Assessment supports compliance with the Work Health and Safety Act and Regulations, strengthens Due Diligence for Officers, and helps protect your business from operational and legal liability.

Risk Categories & Hazards Covered

This document assesses risks and outlines management controls for:

  • WHS Governance, Duty of Care and Consultation: Assessment of leadership responsibilities, consultation arrangements with workers, safety committees, and the demonstration of Officer due diligence in plastic fabrication operations.
  • WHS Planning, Risk Management and Change Management: Management of risk assessment processes, integration of WHS into production planning, and formal controls for design changes, new products, new equipment and process modifications.
  • Plant Procurement, Design and Guarding Systems: Evaluation of plant selection, guarding design, interlock integrity, safety distances, and supplier documentation to ensure compliant and safe plastic fabrication equipment.
  • Hazardous Chemicals, Adhesives and Fumes Management: Control of resins, solvents, adhesives, cleaning agents and process fumes, including SDS management, storage, decanting, ventilation and exposure monitoring.
  • Heat, Thermal Processes and Burn Management: Assessment of hot work, plastic welding, forming, ovens and heat guns, including PPE requirements, process controls and thermal burn prevention strategies.
  • Machine Operation, Automation and Interlocks: Management of operational risks from CNC routers, saws, presses and automated systems, including safe operating envelopes, interlocks, light curtains and emergency stop systems.
  • Noise, Vibration and Environmental Conditions: Evaluation of noise exposure from cutting and routing, vibration, airborne contaminants, lighting, ventilation and thermal comfort in fabrication areas.
  • Materials Handling, Storage and Manual Tasks: Assessment of handling sheet plastics, offcuts and finished products, including racking systems, trolleys, lifting aids, ergonomics and manual handling training.
  • Electrical Safety, Energy Isolation and Maintenance Systems: Protocols for electrical installation compliance, testing and tagging, lock-out/tag-out, stored energy isolation and preventative maintenance programs.
  • Fire, Explosion and Emergency Preparedness: Management of ignition sources, combustible dust, flammable liquids and plastics, along with emergency planning, evacuation, spill response and fire protection systems.
  • Competency, Training and Supervision: Assessment of competency requirements for operators, setters and maintenance personnel, including induction, refresher training, supervision levels and licence verification.
  • Fatigue, Rostering and Psychosocial Risk Management: Control of fatigue from shift work and overtime, workload pressures, supervision practices and psychosocial hazards such as bullying, stress and conflict.
  • Contractor, Visitor and Supply Chain Management: Systems for prequalification, inductions, permits, supervision of contractors and visitors, and management of upstream and downstream supply chain risks.
  • Inspection, Monitoring, Auditing and Continuous Improvement: Implementation of inspection schedules, safety observations, incident reporting, KPI monitoring, internal audits and management review processes.
