Pacific National's fatigue management system is over-reliant on the use of a bio-mathematical model to predict individual fatigue risk, being based principally on rostered work hours without due consideration to higher level fatigue risk management strategies.
Response to safety issue and/or Proactive safety action taken by: Pacific National
Pacific National is in the process of releasing an updated Fatigue Management Standard to meet the requirements of Regulation 29 of the National Law. Pacific National Bulk rail will consider the appropriate use of these bio-mathematical tools as part of the fatigue risk management review process.
ATSB comment/action in response:
The Australian Transport Safety Bureau notes the response provided and is satisfied that the action initiated by Pacific National will, when completed, address the safety issue.
