  3. Is this a problem?

  4. Definitions • Dust • Generic term • Range of potentially hazardous particulates • Nuisance dust • Dust with no inherent toxic profile • Excess can overload lungs

  5. Other particulates Harmful health effects • Silica – lung damage • Metal dusts • nickel – cancer • manganese – manganism • lead – damage to central nervous system, kidneys, blood cells

  6. Latent health effects • Delayed • Onset of health effects following exposure • Insidious • Progressive and often irreversible changes to health

  7. Dust management • Regulatory focus on fibre and dust management in mining • Statutory obligation to manage dust emissions in drilling operations • Obligation to monitor exposures to atmospheric contaminants • Ensure exposures do not exceed occupational exposure standards(OES)

  8. Dust emission points

  9. Controlling dust Use water • Fog • Foam • Binders • Surfactants

  10. Potential controls • Trialling of dust suppression agents (e.g. foam, fog) • Automated sampling • Sample conveyors • Remote operating controls • Operating cabins
