Dust exposure, effects, limits, control

  1. 1. Industrial Dust Matters Exposure / Effects / Limits / Control Mike Slater BOHS President 2014/15
  2. 2. How many people are exposed to dust at work?
  3. 3. Estimated as 9,200,000 4% 11% 9% 5% 9% 8% 9% 24% 9% 9% Source: John Cherrie, IOM
  4. 4. How does exposure occur?
  5. 5. Dust exposures typically occur when: Handling powders Cutting, grinding, drilling etc. Handling friable materials Disturbing dust settled on surfaces
  6. 6. What are the health effects?
  7. 7. Fibrosis
  8. 8. Lung Cancer
  9. 9. 0 1000 2000 3000 4000 Other agents Working as painter Shift work Mineral oils Diesel exhaust emissions Silica Asbestos Occupational cancer deaths by cause in Great Britain, 2005
  10. 10. 0 1000 2000 3000 4000 Other agents Working as painter Shift work Mineral oils Diesel exhaust emissions Silica Asbestos Occupational cancer deaths by cause in Great Britain, 2005
  11. 11. Respiratory disease Irritation Fibrosis COPD Asthma Lung cancer
  12. 12. Evaluating the risks?
  13. 13. HSG173 - A Structured Approach Initial Appraisal Basic Survey Detailed Survey
  14. 14. Brick Making – Silica Exposures 19% 40% 41% > WEL > 50% WEL < 50% WEL
  15. 15. Stone Cutting– Silica Exposures 29% 44% 27% > WEL > 50% WEL < 50% WEL
  16. 16. Risk of silicosis 0 5 10 15 20 25 0 0.04 0.08 0.12 0.16 0.2 0.24 0.28 Exposure to Air Concentration of RCS for 15 Years mg.m-3 PercentageRiskofSilicosis After15YearsWork
  17. 17. Risk of silicosis 0 5 10 15 20 25 0 0.04 0.08 0.12 0.16 0.2 0.24 0.28 Exposure to Air Concentration of RCS for 15 Years mg.m-3 PercentageRiskofSilicosis After15YearsWork
  18. 18. “Low toxicity” dusts “Substantial concentration of dust” • 10 mg/m3 inhalable • 4 mg/m3 respirable
  19. 19. “until safe limits are put in place, employers should aim to keep exposure to respirable dust below 1 mg/m³ and inhalable dust below 5 mg/m³” Institute of Occupational Medicine
  20. 20. “try to ensure that employers follow a precautionary standard of 2.5 mg/m³ for inhalable dust … and 1 mg/m³ for respirable dust.” TUC advice to safety representatives:
