WHAT YOU SHOULD KNOW ABOUT DUST
The effects of respirable Silica dust and strategies to minimise dust emissions
Occupational health and safety legislation states that workers must not be exposed to Respirable Crystalline Silica (RCS) levels above the national exposure standard of 0.05 mg/m3 (in an 8 hour Time Weighted Average period).
Regulations require that exposure to hazardous substances be prevented where practical. If exposure can’t be prevented, the risk must be reduced firstly by controls other than personal protective equipment (PPE). PPE should only be used to manage any remaining risk.
WHAT IS ‘RESPIRABLE CRYSTALLINE SILICA’ (RCS)?
Silica is a natural mineral which is found in rocks, sand and clay. It is thus found in bricks and concrete too. A small fraction of Silica occurs in a sharp, hard crystalline form. Particles smaller than 10 microns in diameter can be breathed directly into the lungs and can cause damage leading to Silicosis. This is called ‘Respirable Crystalline Silica’ or RCS.
Manage dust using control systems
Using local extraction ventilation, either fixed or on-tool
- Shadow vacuuming
- Vacuum clean-up rather than sweeping
- Not blowing dust with compressed air
Manage dust by switching methods
- Use direct fastening methods instead of drilling and anchoring.
- Use wet coring with slurry collection system instead of anchoring.
Manage dust by elimination
Use cast-in channel systems for anchor points for brackets instead of post-installed options
