CNC routers, beam saws, and automated timber machining centres operate at high speeds with substantial kinetic energy stored in spindles and workpieces. While automation reduces operator proximity to cutting zones, hazards emerge during tool changes, workpiece loading, program testing, and maintenance activities where interlocks may be bypassed. Light curtains and safety interlocks are the primary protective devices, and their failure or defeat exposes workers to the same amputation and laceration risks as conventional machines. This template covers automated timber machining centre operations with controls mapped to the binding Plant code effective 1 July 2026.
WHS Regulation 2025 Part 5.1 — Plant; AS 4024 Safety of Machinery series
Work involving powered plant (automated machinery)
Managing Risks of Plant in the Workplace (binding 1 July 2026 under Section 26A)
Yes — Plant code binding July 2026. Non-compliance is a standalone offence.
| Hazard | Consequence | Likelihood |
|---|---|---|
| Contact with rotating spindle or cutter during tool change or maintenance | Amputation, deep laceration | Unlikely |
| Workpiece ejection from vacuum table or clamp failure | Projectile injury, blunt trauma | Possible |
| Entrapment in machine enclosure during maintenance with interlocks bypassed | Crush injury, entanglement, fatality | Unlikely |
| Wood dust from high-speed CNC routing operations | Respiratory disease, nasal cancer (hardwood) | Likely |
| Noise from high-speed spindle and extraction systems | Noise-induced hearing loss | Likely |
Worker's arm crushed by CNC router gantry after light curtain was bypassed during troubleshooting. No permit system for interlock defeat and no lockout procedure in place.
