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 1. Damage Classification 2. Pareto Principle (principle of Critical Few) 3. Energy Damages 4. Patterns of Damage 5. Appropriate Models

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

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

7. Permanent Incapacity - Mining YearQld MiningNSW Mining 2005-2006-134 2006-20073168 2007-20087204 2008-20093962

8. Likelihood (Chance) of Permanent Damage (NSW Mining) 2007-20081 : 98 employee years 2008-20091 : 322 employee years

9. Energy Damages 1. Stable 2. Metastable 3. Unstable 4. Damage 5. Recovery / Repair 6. Stable Framework 3 Damaging Energy

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

11. Appropriate Models  Egocentric  Ergonomic Framework 5

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

13. Observations of an Incident  Essential  Contributory  Non Essential

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

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

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

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

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

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

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 Over 24-73% Under 24-25% Males & Single Vehicle accidents over-represented

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% Driver – fatigue related by definition (2pm – 4pm) (10pm – 6am) 21% Driver – fatigue – fell asleep 17.3%

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