Stabilise safety by stopping, handing over and arranging sleep—not by fighting wakefulness

Reset: Re-read this authored instruction — “Treat head nods, heavy eyelids, drifting attention, repeated rereading, lane drift, missed steps or involuntary sleep as loss of stable wakefulness.” — and its success check, then attempt only this step.

1. Possible snag: The result from “Treat head nods, heavy eyelids, drifting attention, repeated rereading, lane drift, missed steps or involuntary sleep as loss of stable wakefulness.” does not yet meet this declared check: The learner identifies a behavioural sign rather than only “tired”.

   Correction: Return to the start of “Recognise loss of stable wakefulness”, reduce complexity or pace, and repeat only the part needed to satisfy: “The learner identifies a behavioural sign rather than only “tired”.”

Stop / get help: Stop driving or hazardous work for involuntary sleep, head nods, lane drift, repeated errors or inability to track the task.

Reset: Re-read this authored instruction — “At the first safe opportunity, pull over, shut down equipment, step away from heat/water/heights or pause the critical procedure.” — and its success check, then attempt only this step.

1. Possible snag: The handover ends after saying “I am sleepy”.

   Correction: Name the secured equipment, people exposed, unfinished action and the alert receiver who accepted control.

Stop / get help: Stop driving or hazardous work for involuntary sleep, head nods, lane drift, repeated errors or inability to track the task.

Reset: Re-read this authored instruction — “Say “I cannot stay reliably awake and cannot continue safely” to the driver, supervisor or support person.” — and its success check, then attempt only this step.

1. Possible snag: The result from “Say “I cannot stay reliably awake and cannot continue safely” to the driver, supervisor or support person.” does not yet meet this declared check: A named person receives and acknowledges the message.

   Correction: Return to the start of “Tell someone directly”, reduce complexity or pace, and repeat only the part needed to satisfy: “A named person receives and acknowledges the message.”

Stop / get help: Stop driving or hazardous work for involuntary sleep, head nods, lane drift, repeated errors or inability to track the task.

Reset: Re-read this authored instruction — “Give task state, hazards, people affected, unfinished steps and when the next check is due.” — and its success check, then attempt only this step.

1. Possible snag: Music, cold air or pinching is used as a wakefulness check.

   Correction: Secure the hazard and use observed state plus onset history; stimulation is neither a diagnosis nor clearance.

Stop / get help: Stop driving or hazardous work for involuntary sleep, head nods, lane drift, repeated errors or inability to track the task.

Reset: Re-read this authored instruction — “Do not drive yourself. Use an alert driver or safe stopping place and obtain protected sleep opportunity.” — and its success check, then attempt only this step.

1. Possible snag: The result from “Do not drive yourself. Use an alert driver or safe stopping place and obtain protected sleep opportunity.” does not yet meet this declared check: The plan does not depend on the sleepy person navigating or driving.

   Correction: Return to the start of “Choose safe transport and rest”, reduce complexity or pace, and repeat only the part needed to satisfy: “The plan does not depend on the sleepy person navigating or driving.”

Stop / get help: Stop driving or hazardous work for involuntary sleep, head nods, lane drift, repeated errors or inability to track the task.

Reset: Re-read this authored instruction — “Where official or clinical guidance allows, a brief nap and ordinary caffeine may provide temporary alertness; neither proves fitness or replaces recovery sleep.” — and its success check, then attempt only this step.

1. Possible snag: The result from “Where official or clinical guidance allows, a brief nap and ordinary caffeine may provide temporary alertness; neither proves fitness or replaces recovery sleep.” does not yet meet this declared check: The record labels the measure temporary and includes the sleep plan.

   Correction: Return to the start of “Bound temporary countermeasures”, reduce complexity or pace, and repeat only the part needed to satisfy: “The record labels the measure temporary and includes the sleep plan.”

Stop / get help: Stop driving or hazardous work for involuntary sleep, head nods, lane drift, repeated errors or inability to track the task.

Reset: Re-read this authored instruction — “Seek clinical assessment when sleepiness is sudden, recurrent or persists despite adequate sleep; report roster-related fatigue for system correction.” — and its success check, then attempt only this step.

1. Possible snag: The result from “Seek clinical assessment when sleepiness is sudden, recurrent or persists despite adequate sleep; report roster-related fatigue for system correction.” does not yet meet this declared check: The trigger, destination and timescale for review are written down.

   Correction: Return to the start of “Escalate the cause”, reduce complexity or pace, and repeat only the part needed to satisfy: “The trigger, destination and timescale for review are written down.”

Stop / get help: Stop driving or hazardous work for involuntary sleep, head nods, lane drift, repeated errors or inability to track the task.

Reset: Re-read this authored instruction — “After the scene is secure, identify whether sleepiness built gradually after inadequate sleep, appeared suddenly despite adequate rest, included loss of consciousness, or came with weakness, speech change, severe headache, chest symptoms or breathing difficulty.” — and its success check, then attempt only this step.

1. Possible snag: The result from “After the scene is secure, identify whether sleepiness built gradually after inadequate sleep, appeared suddenly despite adequate rest, included loss of consciousness, or came with weakness, speech change, severe headache, chest symptoms or breathing difficulty.” does not yet meet this declared check: The event is labelled gradual expected drowsiness, recurrent unexplained sleepiness or emergency-pattern change, with the observed feature quoted.

   Correction: Return to the start of “Classify how wakefulness changed”, reduce complexity or pace, and repeat only the part needed to satisfy: “The event is labelled gradual expected drowsiness, recurrent unexplained sleepiness or emergency-pattern change, with the observed feature quoted.”

Stop / get help: Stop driving or hazardous work for involuntary sleep, head nods, lane drift, repeated errors or inability to track the task.

Reset: Re-read this authored instruction — “For emergency-pattern change, call emergency services and keep the person safe. For recurrent sudden sleepiness despite adequate opportunity, arrange prompt clinical assessment and suspend driving. For expected schedule-related drowsiness, document the schedule and complete protected recovery.” — and its success check, then attempt only this step.

1. Possible snag: The learner labels an abrupt episode “tired” without recording whether consciousness was lost.

   Correction: Ask whether the person could respond throughout, whether there was a fall and whether confusion remained afterward; route uncertainty to medical assessment.

2. Possible snag: A recurrent sleep attack is managed only by avoiding long drives.

   Correction: Suspend all driving and arrange clinical assessment because short familiar journeys can still contain involuntary sleep.

3. Possible snag: The learner sends the drowsy person alone on public transport despite disorientation.

   Correction: Arrange an alert escort or accessible door-to-door option when navigation or personal safety is impaired.

4. Possible snag: A short nap is treated as evidence that the underlying cause has resolved.

   Correction: Label the nap as temporary recovery and keep the medical or schedule-review trigger active.

Stop / get help: Stop driving or hazardous work for involuntary sleep, head nods, lane drift, repeated errors or inability to track the task.
