Learning outcome

Describe a task-based hazard review and the hierarchy of controls for wood dust.

Recognize the exposure

Cutting, routing and sanding create airborne particles. Wood dust can cause respiratory symptoms and other serious health effects; being outdoors does not establish that exposure is controlled. Identify the species, operations, duration, nearby workers and any finishes or treatments that could add hazards. Consult material and equipment information and applicable workplace requirements.

Control the task, not just the worker

Prioritize suitable extraction and other engineering controls at the point of generation. Use guarded equipment, suitable tooling and safe material support. Plan housekeeping that does not redistribute dust. Respiratory protection is not a replacement for exposure assessment and effective controls; where required, selection, training, medical evaluation and fit testing must follow the applicable program requirements.

Inspect and communicate

Check extraction operation and collection equipment before work, then monitor performance as the task changes. Consider noise, eye injury, manual handling, fire risks and access as part of the same review. Define stop-work conditions and explain them to the crew. Record corrective actions rather than treating a signed checklist as proof that all risk has been removed.
