Penyelesaian Risiko & Keselamatan

Masalahnya

Insiden serius mesti disiasat. Sedikit sahaja siasatan yang bertanya tentang keletihan dengan sewajarnya.

Keletihan mudah didakwa tetapi sukar dibuktikan selepas kejadian. Siasatan cenderung sama ada terlepas pandang atau terus menyalahkannya tanpa menguji penjelasan alternatif.

Was It Fatigue? memberi penyiasat anda cara yang konsisten dan boleh diulang untuk bertanya, serta rekod yang menunjukkan penjelasan alternatif telah diuji.

Charter bus crash that killed 10: operator and directors fined $674,000 incl. fatigue management failures
- Keselamatan

- Kewangan
After a charter bus crash in regional New South Wales killed 10 people and seriously injured 25, the National Heavy Vehicle Regulator prosecuted the bus company and its two directors. They pleaded guilty to Heavy Vehicle National Law safety duty breaches covering inadequate driver recruitment, failure to manage overspeed in a timely way, and fatigue management failings. The court fined the company $650,000 and each director $12,000, with proceedings against two managers still pending.

Police search and rescue coordinator recalled after a full shift and kept on duty for about 30 hours fails to act as a sinking boat's occupants are lost - coroner says fatigue may well have contributed
- Keselamatan
- Undang-undang
A government vessel became lost in fog and sank in remote northern waters; none of the five people on board, including a young child, survived. The police sergeant acting as local search and rescue coordinator had been recalled to duty at about 4pm after working a full shift and stayed on duty until after 10pm the next day. The State Coroner found he failed to take decisive action or pass on that the boat was sinking, called his hours inappropriate and found his fatigue may well have contributed to his errors of judgement, and referred his conduct for consideration of disciplinary action.

Interstate driver on 7.5 hours' sleep in five days has microsleeps and kills six; jailed and denied compensation
- Keselamatan
- Undang-undang
An interstate semi-trailer driver drove about 5,400 km in five days, sleeping only about seven and a half hours and using stimulant pills to stay awake. For about 90 km before the crash site his truck weaved onto the wrong side of the road until it collided with two cars, killing six people. The state coroner found his driving was substantially caused by extreme fatigue resulting in microsleeps; he was jailed for death by dangerous driving, and the Workers Compensation Tribunal later refused his own injury claim because he kept driving knowing he was falling asleep.

A heavy vehicle struck and killed four police officers at a roadside intercept on a Victorian freeway in 2020.

Tanker collision: officer of the watch had under 2 hours' rest in 38.5
- Keselamatan
In 2024 a Singapore-registered tanker collided with another tanker in the South China Sea; both ships caught fire and a shore worker on the other tanker later died. Singapore's Transport Safety Investigation Bureau found the officer of the watch had under two hours' unbroken rest in the 38.5 hours before his midnight watch and was likely fatigued. He had joined after overnight travel, and an unannounced fire-alarm test woke him.

Minibus driver who fell asleep from lack of rest kills pedestrian on zebra crossing
- Keselamatan

A minibus driver carrying young children briefly fell asleep at the wheel around midday because of a lack of rest, failed to see a pedestrian on a zebra crossing and struck her; she died six days later. The driver, then in his late 60s, pleaded guilty to driving without due care and attention causing death. The judge named his fatigue, and the risk it posed to others, as an aggravating factor and imposed jail and an eight-year driving ban.

Military inquiry: unauthorised night punishment cut trainees' rest before fatal fast march

A full-time national serviceman collapsed with heat stroke during an 8km fast march and later died. A military Committee of Inquiry found that the night before, commanders had held unauthorised physical punishment that cut the platoon's required seven hours of uninterrupted rest to about six hours 15 minutes, even though the pre-march safety check asked whether trainees had that rest. The inquiry listed accumulated fatigue and insufficient rest among the possible contributing causes, and the commanders involved were removed from command.

Bus captain on 4 hours' sleep closes eyes for 3 seconds and crashes; jailed 12 weeks
- Keselamatan
- Undang-undang
A public bus captain who had slept only about four hours before starting a 5:30am shift dozed off at the wheel mid-afternoon, closing his eyes for about three seconds before the bus crashed into a bus stop bollard. Three of the ten passengers were injured, including fractures. The prosecution told the court the crash was caused by his lack of sleep; he was jailed for 12 weeks and banned from driving for five years. The operator said its roster gave at least nine hours' rest between shifts, a reminder that a compliant roster does not guarantee that sleep was actually obtained.

A structured answer to “was it fatigue?”

After an incident or near miss, investigators work through a structured method: was fatigue present, and was the error the kind fatigue produces once other explanations are tested? It sits at the last level of defence, after something has gone wrong, and feeds each finding back into the levels before it: rosters, sleep and in-shift controls.

Lima tahap pertahanan

Step 01
Kejadian
Penyiasat membuka penilaian bagi sesuatu insiden tertentu.
Step 02
Adakah keletihan wujud?
Fatigue Likelihood Score (skor kebarangkalian keletihan), daripada empat soalan: tertidur sejurus sebelum kejadian, simptom tingkah laku dalam lima belas minit sebelumnya, sejarah tidur dan jaga terdahulu, dan peluang tidur dalam jadual giliran.
Step 03
Adakah ia kesilapan jenis keletihan?
Fatigue Error Likelihood Score (skor kebarangkalian kesilapan akibat keletihan) menguji penjelasan alternatif pada setiap tahap sebelum mengaitkan kesilapan itu dengan keletihan.
Step 04
Dapatan gabungan
Fatigue Attributable Likelihood Score (skor kebarangkalian boleh dikaitkan dengan keletihan) pada jalur 1–5 dengan laluannya dinamakan, yang disalurkan kembali ke kawalan jadual giliran, tidur dan semasa syif.

After an incident, fatigue is either missed or blamed without testing the alternatives. Neither helps the people involved, and neither tells you which control failed. I wanted investigators to have a consistent way to ask the question properly, and a record that shows they did.

Bukti

Apa yang dapat kami tunjukkan

Reka bentuknya memerlukan kedua-dua kehadiran keletihan dan kesilapan yang mempunyai ciri khas keletihan, serta menguji penjelasan alternatif sepanjang proses. Itulah yang menghalangnya daripada membuat kesimpulan sebab-akibat berdasarkan keletihan semata-mata.

Ia satu-satunya produk dalam rangkaian ini yang meneliti semua tahap, termasuk kecukupan jadual giliran, secara retrospektif selepas sesuatu kejadian.

Apa yang tidak dibuktikannya

Ia bersifat retrospektif. Ia tidak meramalkan kejadian, tidak menganggarkan saiz populasi, dan satu siasatan tidak membuktikan sesuatu corak. Ia bukan instrumen yang disahkan dan tiada dakwaan pengesahan dibuat untuknya. Rekod yang dihasilkan boleh tertakluk kepada pendedahan dalam prosiding undang-undang.

In practice

Rail · North America

A Class I railroad uses Was It Fatigue? to determine whether fatigue contributed to an incident or near miss.

Its investigators ask the same structured questions after every event, so each record assesses how likely it is that fatigue was present and that the error was the kind fatigue produces, and shows which other explanations were tested.

FAQs

Questions we’re often asked

Who uses it?

Your investigators, who open an assessment against a specific incident or near miss.

How does it avoid blaming fatigue by default?

It requires both the presence of fatigue and an error of the kind fatigue produces, and tests alternative explanations at every level before attributing an error to fatigue.

What does the finding look like?

A Fatigue Attributable Likelihood Score on a 1–5 band with the fatigue pathway named, which feeds back into roster, sleep and in-shift controls.

Is it a validated instrument?

No, and no validation claim is made for it. It is a structured, repeatable method. It is retrospective: it does not predict an event, and one investigation does not establish a pattern. Records produced are discoverable.

How is it priced?

On investigation volume, not headcount: it is the only event-priced product in the suite.

How pricing works

How is investigation data protected?

The platform is certified to ISO/IEC 27001:2022.
