  1. VALIDATION OF THE ARRB FATIGUE MONITORNICK MABBOTT - ARRB Transport Research Ltd.

  2. THE PROBLEM • Fatigue has become recognised as a contributing factor in workplace incidents • Relationship between fatigue & the combination of sleep, work periods & time of day is complex • Humans cannot predict how long they can remain awake • Personnel will not always comply with fatigue management programs

  3. FITNESS FOR DUTY TESTING • POSITIVES: • Assessment of whether or not worker should commence shift; • Has reduced irresponsible social behaviours; • Has added to an increased healthy lifestyle.

  4. FITNESS FOR DUTY TESTING • NEGATIVES: • Lack of published scientific validation data; • Momentary test at start times; • Not practical to administer tests throughout shifts; • Cannot predict human performance variations.

  5. ARRB Fatigue Monitor • A stimulus - reaction task capable of early fatigue detection • Concept based on slow reactions indicating effects of fatigue • Tests throughout the whole shift • Early warning to operator and supervisor

  6. DEVICE TRIAL • Current trial at Hamersley Iron - WA • Four dump trucks fitted with devices • 23 operators being tested - voluntarily • Testing 24 hrs day • Testing over three month period

  7. RESULTS THUS FAR • Over 200 hours of test data • Data showing time of day performance effects • Clear circadian patterns • Some anomalies in the data

  8. TIME OF DAY EFFECTS • Performance decrements between: • Midnight & 6 AM - 53% • 6 AM to Midday - 12% • Midday to 6 PM - 16% • 6 PM to Midnight - 18%

  9. THE FUTURE OF THE TRIAL • Data showing that the device is collecting evidence of circadian performance decrements • Warning signals are being presented to control room to allow for intervention • Operators have been changing crib breaks and machinery - Much discussion • Large database will be developed to answer industry questions

  10. BENEFITS TO MINING • It will save lives and reduce injuries • Reduce costs associated with accidents, inc damage & down-time • Data can be used to identify shifts & rosters that place employees ‘at risk’ • The device will be a scientifically proven and cost-effective solution
