Le problème

Un horaire conforme peut quand même mettre au travail une équipe fatiguée

Le prédicteur opérationnel de la détérioration liée à la fatigue est l’historique de sommeil et d’éveil antérieur, et non les heures de service. Les règles sur les heures de service ne voient pas la nuit passée auprès d’un enfant malade ni le trouble du sommeil que personne n’a diagnostiqué.

Fatiguefit4Duty pose, au début du quart, les questions qui prédisent réellement la détérioration, et place la réponse devant la personne qui doit prendre la décision.

Cas

When no one checked who was fit for duty

Published cases from Canada where people started or kept working without enough sleep, and fatigue was never measured or treated as a hazard.

Les cas sont présentés en anglais.

janv. 2004 · Ontario, Canada
Charter pilot on about 5 hours' sleep after cross-continent trip takes off iced and overweight; 10 killed
- Sécurité
- Financier
A single-engine turboprop on a charter flight took off from an island airstrip in freezing precipitation, about 15 percent over its maximum weight and with ice on the airframe, and struck the frozen surface of a lake, killing the pilot and all nine passengers. The Transportation Safety Board of Canada found the decision to take off was out of character for the pilot and was likely affected by stress and fatigue. The night before, he had returned from a trip to California across three time zones and could have slept at most 5 hours 15 minutes before reporting for duty at 4:45 am.

Fatigued supervisor misses hazard; explosion on offshore oil shuttle tanker kills crew member
- Sécurité
A shuttle tanker carrying crude oil from an offshore oil field was at anchor while welders repaired a cargo tank. Oil residue had flowed back into the tank and the vapour exploded when welding began, killing one crew member and badly burning the welder. The Transportation Safety Board of Canada found that the officer overseeing the job had a heavy safety-critical workload and was working while fatigued, after days of continuous cargo and tank-cleaning work with disrupted sleep and less rest than required, and that the ship's safety manual did not treat fatigue as a risk.

août 1999 · Quebec, Canada
Commuter crew far over flight-time limits, first officer chronically fatigued; turboprop crashes on approach
- Sécurité
- Juridique
A commuter turboprop on a scheduled night flight from an island community crashed one nautical mile short of the runway at a regional airport in fog, killing the captain and seriously injuring the first officer. The Transportation Safety Board of Canada found both pilots had exceeded their maximum monthly, quarterly and daily flight and duty times, and that the first officer had averaged 14-hour days for 30 days with one day off and had told the captain he was too tired and worn out. The national regulator was unaware of the exceedances and the company did not effectively supervise pilot duty times.

Yard helper with 4 hours' sleep in 38 sets wrong switch and is fatally struck
- Sécurité
A yard helper with a national railway was struck and killed by a reversing yard movement at a major rail yard at about 6 a.m. He had worked 7 of the previous 9 nights, was on his second consecutive night shift and had slept at most 4 hours in the previous 38. The Transportation Safety Board of Canada found his fatigue likely contributed to the incorrect alignment of a crossover switch that led to the accident, alongside the absence of a risk assessment and a task interruption.

Precast-concrete truck driver with at most 7.5 hours' rest in 29 hours runs off the highway and is killed; regulator blames hypovigilance and schedule management
- Sécurité
A heavy-vehicle driver for a precast concrete manufacturer was driving back to the plant at about 4:20 am after an overnight bridge-beam delivery when his truck went straight on at a work-zone lane diversion on a highway and hit a fence; he died at the scene. The Quebec workplace safety regulator found that the driver's hypovigilance caused the run-off and that the employer's management of work schedules exposed him to the dangers of driving while hypovigilant. Over the 29 hours before the crash he had at most about 7.5 hours of sleep or rest, schedules were prepared without regard to the heavy-vehicle hours-of-service rules, and the employer had no fatigue management program or policy.

Snow-hauling truck driver awake more than 24 hours drives off with dump body raised and is killed; regulator faults employer's schedule management
- Sécurité
At about 4:25 am a dump-truck driver for a snow-removal contractor, hauling snow overnight, left a snow dump with the dump body still fully raised while talking on the phone; about a kilometre later it struck an overpass, the body was torn off and he was partly thrown from the cab and killed. The Quebec workplace safety regulator found he had been awake more than 24 hours and had worked 25 h 10 min within a 30 h 55 min work shift, which put him under a driving prohibition under the hours-of-service rules. It found that his hypovigilance, combined with the phone call, led him to forget to lower the dump body, and that the employer's failure to manage work schedules exposed him to hypovigilant driving.

Engineer awake 23 hours, afraid to book off, derails 13 cars in rail yard
- Sécurité
A freight train run by a national railway derailed 13 cars in a major rail yard after the locomotive engineer applied too much power through a sharp curve. The Transportation Safety Board of Canada found the engineer was likely fatigued from two weeks of poor-quality sleep and being awake for at least 23 hours, which limited his working memory and vigilance. He had felt unfit when called for duty but feared discipline if he refused, and the board warned that fatigue procedures which do not let workers remove themselves from duty without fear of discipline increase the risk of fatigued employees reporting for work.

janv. 2012 · British Columbia, Canada
Sleepless captain presses on with unstable approach; passenger jet overruns runway
- Sécurité
A jet airliner on a charter flight carrying 112 workers from Alberta to a remote town in northern British Columbia ran 230 feet off the end of the runway after an unstable, long landing; no one was hurt. Investigators found the captain had little or no sleep in the previous 24 hours because his accommodation was noisy and hot, and that he had considered calling in sick but felt it would not be viewed favourably. Fatigue likely caused attention lapses and a fixation on salvaging the approach instead of going around.

Engineer with under 2 hours' sleep in 24 derails 21 cars including LPG tank cars; homes evacuated
- Sécurité
A freight train derailed 21 cars, including loaded liquefied petroleum gas and fuel oil tank cars, and homes and businesses within 1.6 km were evacuated. The Transportation Safety Board of Canada found the locomotive engineer had slept only 1 to 1.5 hours before being called for work and had less than 2 hours' sleep in the previous 24 hours. It found he was insufficiently rested for safety-critical work, and that because workers decide for themselves whether they are fit to work, a fatigued employee facing lost wages or discipline is more likely to accept a shift.

Captain with heavy sleep debt and 18 hours awake slips at 70 ft; passenger jet overruns runway
- Sécurité
A low-cost airline's narrow-body jet with 134 passengers overran the end of the runway at a regional airport at 6:25 am after the captain inadvertently pressed the go-around switch at about 70 feet, causing one engine to advance to near-maximum thrust during the landing roll. The Transportation Safety Board of Canada found the captain had built up a significant sleep debt over the previous week of night duties and had been awake for nearly 18 hours, at the end of the circadian low, and that this fatigue reduced his attention and made the slip more likely. The Board also found that when pilots do not monitor their own sleep debt, fatigue can go undetected and unmanaged.

Comment ça fonctionne

A fitness-for-duty check at the start of the shift

Each person records the sleep they actually got in the last 24 and 48 hours and how alert they feel now. That covers two levels of defence at once: whether the sleep was obtained, and whether fatigue is showing at work. Elevated risk goes to the leader with the controls you have set for the role and task, before the work starts.

Les cinq niveaux de défense

Step 01
Déclenchement
Un superviseur déclenche l’évaluation au début du quart. Environ trente secondes, sur un téléphone, et elle fonctionne hors ligne.
Step 02
Sommeil et vigilance
Sommeil obtenu au cours des 24 et 48 dernières heures, temps d’éveil et somnolence actuelle selon la Karolinska Sleepiness Scale.
Step 03
Indication du risque
La probabilité, établie à partir de l’historique de sommeil et d’éveil antérieur, combinée à une cote de conséquence attribuée selon le rôle, dans un calcul conforme à ISO 31000.
Step 04
Transmise au responsable
Le résultat est transmis au chef d’équipe ou au gestionnaire de la sécurité, avec les contrôles par rôle et par tâche que vous avez configurés. La décision vous revient.

Most workplaces check whether someone is fit for duty without asking how they slept. A roster can’t see a night with a sick child. Thirty seconds at the start of a shift asks, and puts the answer in front of whoever makes the call.

Données probantes

Ce que nous pouvons démontrer

Le volet probabilité repose sur l’historique de sommeil et d’éveil antérieur, la donnée individuelle d’aptitude au travail la mieux appuyée par les données probantes.

L’approche suit la littérature publiée sur la gestion des risques liés à la fatigue (Dawson & McCulloch, 2005; Dawson & Sprajcer, 2020). La notation, les catégories et les seuils sont les nôtres, et aucune étude de validation n’est revendiquée à leur égard.

Ce que le produit n’établit pas

L’outil produit une indication du risque à l’échelle du rôle et de la tâche. Il ne détermine pas l’aptitude au travail, ne pose pas de diagnostic et n’autorise ni ne retire un employé du travail. Cette décision vous revient, selon votre propre procédure. C’est une méthode défendable, et non un instrument validé, et nous ne la présentons pas comme telle.

FAQs

Questions we’re often asked

Does it decide whether someone can work?

No. It gives a risk indication at role and task level, shown to the team leader or safety manager with the controls you have configured. It does not clear or stand down an employee: that decision stays with you, under your own procedure.

How long does it take, and does it need a signal?

Around thirty seconds on a phone at the start of duty, and it works offline.

What does it ask?

The sleep a person got in the last 24 and 48 hours, how long they have been awake, and how sleepy they feel now on the Karolinska Sleepiness Scale, combined with a consequence rating set for each role.

Is it a validated instrument?

No, and we don’t describe it as one. It follows the published fatigue risk management literature, but the scoring, bands and thresholds are our own and no validation study is claimed for them. The thresholds and how they were derived are published to you.

Who sees an individual’s result?

The team leader or safety manager, by design: the result exists to inform a control decision at the start of duty, so it is not private to the worker. You also get aggregate reporting by cohort, location and craft.
