Fatigue & Safety in Mining –A Distraction?

Explore the correlation between fatigue and safety in mining operations, emphasizing effective strategies to mitigate on-site damage. This analysis delves into the impairment caused by fatigue on mental and physical functions, proposing frameworks and models for damage classification and prevention. By understanding the Pareto Principle and energy damages associated with mining, this discussion highlights the importance of proper training, fatigue management, ergonomic designs, and other safety measures to reduce the likelihood of fatal and non-fatal incidents. Case studies and risk assessment data further underscore the significance of addressing fatigue-related risks in the mining industry. Stay informed to prevent potential accidents and protect the well-being of workers.

  1. Fatigue & Safety in Mining –A Distraction? Roger Kahler InterSafe

  2. Fatigue Impairment of mental and physical function

  3. Hypothesis Effective Fatigue Management will not significantly alter on-site personal damage – fatal and non-fatal

  4. Frameworks of Thinking Damage Classification Pareto Principle (principle of Critical Few) Energy Damages Patterns of Damage Appropriate Models

  5. Framework 1 and 2 Damage Classification & Pareto Principle (80/20 Rule) Permanent Fatal Non Fatal Temporary Minor

  6. Numbers of People Involved in Non-Fatal Permanent Damage Australia (All Industries) 175 / Day

  7. Permanent Incapacity - Mining

  8. Likelihood (Chance) of Permanent Damage (NSW Mining)

  9. Framework 3 Energy Damages • Damaging Energy Stable Metastable Unstable Damage Recovery / Repair Stable

  10. Framework 4 Pareto Damaging Energies – Fatal and Non-Fatal Permanent Vehicular Gravitational Human

  11. Framework 5 Appropriate Models Egocentric Ergonomic

  12. Framework 5 Appropriate Models Egocentric Safe acts and conditions Unsafe acts and conditions Ergonomic Did/did not Present/Absent

  13. Observations of an Incident Essential Contributory Non Essential

  14. Human Energy – Over-exertion • Training in lift technique? • Fatigue management? • Task Ergonomics? Solve by which strategy -

  15. Gravitational Energy – Fall to Same Level • Watch where you’re walking? • Fatigue Management? • Underfoot surface conditions? Solve by which strategy -

  16. Vehicular Energy – Jolt/Jar/Vibration • Watch where you’re driving? • Fatigue Management? • Road conditions (short term)? • Equipment design (longer term)? Solve by which strategy -

  17. Gravitational Energy – Descend Mobile & Fixed Plant • Training in 3 points of contact? • Fatigue Management? • “Ergonomic” Designs? Solve by which strategy -

  18. Vehicular Energy – Fatal – Over Embankment / Edge • Be Careful? • Fatigue Management? • Some combination of Bunds, Berms, Seatbelts, ROPS, Lighting, Drainage etc. Solve by which strategy -

  19. Proposition Effective Fatigue Management will not significantly alter ‘on site’ personal damage (fatal, non-fatal) Proposition - TRUE

  20. 24 Hrs without sleep 20km/hr faster than other traffic 0.08 BAC Driving using mobile phone 16km/hr faster than other traffic 0.05 BAC 17 Hrs without Sleep 8-10km/hr Faster than Other traffic 100km/h 0 Summary of Relative Risk 7 x6 6 5 Relative Risk x4 4 x2 3 2 1 0 25 15 20 -5 0 5 10 -10 Relative Speed (km/h)

  21. Peak Downs Highway(Gregory Development Road – Hazledean)Serious Casualties as a result of 41 crashes – 2004-2008 5 Fatalities 47 Hospitalisations

  22. Age Groups Males & Single Vehicle accidents over-represented Over 24 - 73% Under 24 - 25%

  23. Time of Day Midnight – 6am - 9.6% 6am – Noon - 26.9% Noon – 6pm - 48%

  24. Head On - 17.3% Off Carriageway - 36.5% Other - 46.1%

  25. Fatigue – 38%

  26. Closing Comment Fatigue and Health Fatigue and Off-Site Road Incidents (Fatal & Hospital)
