The obligation
PCBUs must monitor and control dust (including silica) generated during abrasive blasting and may need to arrange health monitoring for workers exposed to hazardous dust.
The NT Abrasive Blasting Code of Practice (Code s 3.2–3.3) requires PCBUs to identify, assess, and control dust hazards, including respirable crystalline silica. Health monitoring obligations arise under the NT WHS Regulations where workers are at risk of silicosis or other dust-related disease. The Code details engineering controls (enclosures, ventilation, wet methods) as preferred controls over PPE.
