Fatigue — The Invisible Impairment

6 minutesCrew talk · print & deliver

No one would let a drunk workmate drive the forklift — but a workmate on four hours of sleep performs about the same. Fatigue slows reactions, narrows attention and makes shortcuts irresistible. Night shift, second jobs and long commutes make it an everyday hazard.

Know the signs

  • Micro-sleeps, drifting concentration, missing radio calls, irritability.
  • Fixating on one thing while missing the obvious — tunnel vision.
  • 'I don't remember the last five kilometres' on the drive in.

Manage it honestly

  • Protect your sleep window on shift cycles — dark, cool, phone away.
  • Declare it: telling your supervisor you are not sharp is a professional act, not a weakness.
  • High-risk tasks (working at height, isolation, driving) get rescheduled or reassigned when someone is running empty.
  • Caffeine is a delay, not a repair.

Discussion — ask the crew

  1. Which tasks on this site should a fatigued person never do?
  2. What happens — honestly — when someone declares fatigue here?
  3. What time pressure pushes people to work tired, and how do we fix it?
