Respiratory Protection — Dust & Silica

Talking Points

1. 1 When cutting, grinding, or chasing concrete/brick/stone: ALWAYS use a dust extractor or wet-cutting method — never dry cut without vacuum extraction
2. 2 A basic paper dust mask is NOT sufficient for silica — use a P2 or P3 respirator rated for silica particles (AS/NZS 1716)
3. 3 Fit-check your respirator: mould nose piece, pull straps evenly, check for facial hair that breaks the seal
4. 4 Silica work requires a controlled work area — other workers not involved in the task must be kept clear
5. 5 Dispose of filter cartridges and silica-contaminated cloths as hazardous waste — do not leave lying around
6. 6 If you experience shortness of breath, persistent cough, or chest pain after silica work — see a doctor and mention silica exposure
7. 7 Note: engineered stone (Reconstituted stone / quartz composite) has very high silica content — special precautions required under national silicosis strategy

Control Measures

• PPE assessment conducted for all tasks generating dust — correct RPE specified in SWMS
• P2/P3 respirators available and fit-tested to each worker
• Dust extraction equipment checked before each use — vacuum filter maintained
• Wet-cutting methods preferred wherever possible
• Air monitoring conducted for extended silica work (>1 hour/day)
• Health surveillance program for workers regularly exposed to silica
