Human Factors and Fatigue Management Policy

Purpose. This policy addresses the human factors that contribute to maintenance error and sets the limits and controls for fatigue on shift work.

1.Purpose and scope

Most maintenance errors involve human factors such as fatigue, pressure, distraction, poor communication and complacency. This policy applies to all technical and support staff at every site and to contractors working under the business's approval.

2.Human factors training

Every technical worker must complete initial human factors training before certifying or performing unsupervised maintenance and refresher training every two years. Training will cover the dirty dozen contributing factors, error management, communication at shift handover and the reporting system.

3.Shift limits

Rostered shifts must not exceed twelve hours and total duty must not exceed fourteen hours including overtime. Workers must have at least ten hours free of duty between shifts and at least two consecutive days free of duty in every fourteen. Night work on flight critical tasks will be avoided unless an independent inspection is arranged.

• Maximum twelve hour rostered shift
• Maximum fourteen hours total duty
• Minimum ten hours free of duty between shifts
• Two consecutive days off in every fourteen

4.Fitness for duty

Workers must present fit for duty and must tell their supervisor if they are fatigued, unwell or affected by medication. Supervisors must remove a worker from safety critical tasks when fitness is in doubt without penalty to the worker.

5.Task interruption and handover

Interrupted tasks must be re-started from the last verified step, not from memory. Every shift handover must use the Shift Handover Record Template so that the incoming crew knows the exact state of each task, including open panels, disconnected systems and tools issued.

6.Review

The safety committee will review fatigue reports, overtime hours and error reports monthly and this policy annually.
