Thicknessers and jointers (surface planers) use high-speed rotating cutter blocks that can grab and eject timber at extreme velocity, causing severe blunt trauma injuries to operators and bystanders. The exposed cutter block on a jointer is one of the most dangerous guarding challenges in any woodworking workshop because the guard must allow timber feed while preventing hand contact. Thicknessers generate substantial wood dust volumes and noise levels that routinely exceed 90 dB(A). This template covers both machine types with controls mapped to the binding Managing Risks of Plant code effective 1 July 2026.

Work involving powered plant
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 |
|---|---|---|
| Cutter block contact on jointer during feed operation | Finger and hand amputation, deep laceration | Possible |
| Timber kickback from thicknesser feed rollers | Blunt trauma to operator, projectile injury to bystanders | Possible |
| Entanglement with feed rollers during clearing or adjustment | Crush injury to hands and fingers, degloving | Unlikely |
| Wood dust generation during planing operations | Nasal cancer (hardwood), respiratory disease | Likely |
| Noise exceeding 90 dB(A) during planing operations | Noise-induced hearing loss (irreversible) | Likely |
Worker's fingers severed after contact with jointer cutter block. Bridge guard had been removed for wide board planing and not replaced. No lockout procedure for cutter changes.
