    Acutely fatigued trawler master who stayed at the helm through a 3-day redfish trip slow to respond as vessel sinks; three die

    • Sécurité

    The master of a stern trawler stayed at the helm for most of a three-day redfish trip with only occasional breaks, and gear failures disrupted his and the crew's sleep. About four hours after the crew stood down to rest, the overloaded vessel began to sink during the night. The Transportation Safety Board found that the master was acutely fatigued, which likely reduced his ability to recognize and respond to the emergency. Three of the six people on board died.

    Arbitrator rules nurse ordered to work 31 hours in 39 was subjected to abuse of management rights

    • Juridique

    A nurse in a regional Quebec public health service was ordered to work three consecutive shifts totalling more than 31 hours within a 39-hour period, and when she raised fatigue and said she could not continue, her manager threatened to call the police. The arbitrator found the practice went well beyond the limits generally accepted by the courts, that the employer had abused its management rights and created unreasonable working conditions, and ordered it to end all similar practices. The ruling reinforced earlier tribunal guidance that mandatory overtime should be used only in urgent and exceptional situations.

    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.

    Pilot boat deckhand on day 7 of 7, awake 18 hours, likely fatigued when he went overboard and died

    • Sécurité

    Near midnight, during a pilot transfer off a harbour entrance, the deckhand of a pilot boat went overboard while untethered and died. The Transportation Safety Board found that the tether system design and the vessel's limited recovery capability caused the death. It also found that the deckhand, on the last day of a 7-day shift and awake for 18 hours, faced multiple fatigue risk factors and was likely fatigued, and that crews on irregular schedules without effective fatigue risk management are at increased risk of impairment.

    Gillnet crew awake over 21 hours after 21.5-hour work period; fatigued crew member entangled and pulled overboard

    • Sécurité

    Two crew members on a factory freezer fishing vessel were setting gillnets for turbot at about 03:00. They had started work at 05:30 the previous morning and worked 21.5 hours with one break of 1.75 hours, during which they did not nap. One crew member's arm became entangled in the buoy line and he was pulled overboard and died. The Transportation Safety Board found that both crew members had sleep-related fatigue that reduced their ability to stay alert to risks, and that this, with an adapted work method, led to the death.

    Snow crab crew awake 34 to 37 hours napping below; flooding missed and sleep inertia slows abandonment of capsizing boat

    • Sécurité

    On the opening day of the snow crab season, which began at midnight, the master of an open fishing vessel had been awake about 37 hours and the crew about 34 hours, with only short, poor-quality naps. To get needed sleep, all but one crew member were napping below while an inexperienced crew member steered, and water building up in the vessel went unnoticed until it capsized. The Transportation Safety Board found that sleep inertia likely affected the master's recognition of the danger and the abandonment. One crew member died and the master was not found.

    A mould operator at a mattress plant was caught on video sleeping during his shift and denied it, saying he was 'just relaxing'. The arbitrator found he was clearly asleep, but that dismissal was an overreaction for a worker with nine years' discipline-free service. Because trust had broken down, reinstatement was refused and the employer was ordered to pay about 11 weeks' notice plus a 15% top-up and benefits instead.

    Scallop crew on 8-on, 4-off schedule without restorative sleep woken as vessel sinks; fatigue cuts survival chances, six lost

    • Sécurité

    A scallop dragger capsized and sank before dawn while returning from the fishing grounds with unshucked scallops on deck. The crew worked 8 hours on and 4 hours off, which the Transportation Safety Board found would not have allowed restorative sleep, and some were probably woken from sleep when the emergency began near the circadian low. The Board found that fatigue and being woken from sleep, together with cold water, darkness and hard-to-reach escape routes, significantly affected the crew's chances of survival. All six crew died or remain missing.

    A national railway's signal maintainer working long consecutive night shifts put his hi-rail track unit on the north main track when he meant to use the south track. An intercity passenger train struck the empty, stationary unit at nearly 83 mph and dragged it about 2,500 feet. The TSB found he had probably built up a sleep debt from many consecutive night shifts and daytime sleep, and warned that such schedules create high-risk situations.

    A regional jet began its take-off roll at a major airport without a take-off clearance while a wide-body airliner was crossing the runway; the crew aborted the takeoff when they saw the other aircraft over the crest of the runway. The Transportation Safety Board of Canada found the captain had three fatigue risk factors - acute sleep disruption, chronic sleep disruption and circadian rhythm disruption from moving from late evening to early morning shifts - and was experiencing some fatigue, but could not determine whether fatigue contributed. It found as a risk that backward-rotating shift schedules raise fatigue risk when crews lack time off to adapt.

    A national railway's freight train ran past restrictive signals and side-collided with another of the railway's freight trains at 23 mph. The TSB found the locomotive engineer was fatigued after two nights of abbreviated and disrupted sleep, which together with low workload under the trip optimizer delayed his reaction and led to a poor braking choice. Two crew members jumped from the locomotive and were slightly hurt.

    National railway found in contempt and fined C$200,000 for keeping train crews on duty past rest limits

    • Juridique
    • Financier

    After an arbitrator ordered a national railway in 2018 to stop breaching collective agreement rules that require train crews who give rest notice to be relieved within 10 hours (12 hours otherwise), the union documented continuing breaches. The Federal Court found the railway guilty of contempt of court in 22 of 38 alleged incidents between 2018 and 2019, rejecting its argument that the breaches were beyond its control because it had achieved 99% compliance in some periods. The court described the rest provisions as inherently safety driven and later imposed a C$200,000 penalty.

    A food plant maintenance worker repeatedly refused night-shift assignments, producing medical notes saying rotating shift work disturbed his sleep and caused headaches. The arbitrator found the notes only supported a need for steady shifts with minimal disruption, not a ban on night work, and that he had refused direct orders without first raising medical concerns. His termination under progressive discipline was upheld.

    Conductor's 'fatigued' unfit book-offs after rest days ruled pattern absenteeism; book-unfit clause 'not intended to serve as a shield'

    • Juridique

    A national railway's conductor booked unfit on several occasions, including twice saying he was fatigued and not properly rested, once straight after two rest days. The railway dismissed him for patterned absenteeism, and the union argued the collective agreement bars discipline for booking unfit. The arbitrator agreed the book-unfit clause exists so employees are rested and fit and can be used without fear of discipline in appropriate circumstances, but held it is not a shield for a pattern of book-offs that extend weekends or days off. Given his long service, he was reinstated without compensation on strict attendance conditions.

    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.

The crew had logged almost 10 hours of low-altitude flying in 12 hours that day. The TSB found that mental fatigue, sensation seeking and altered risk perception very likely contributed to the low flying.

    Freight crew 2 to 3 hours short of sleep after a shifting call time strike the rear of a train; TSB flags unpredictable calls as a fatigue risk

    • Sécurité

    A national railway's freight train passed a restricting signal too fast and hit the tail end of another train at 18 mph, after the crew misheard a radio signal call and believed the train ahead was farther away than it was. The crew had gone to bed expecting to work at about 0100, woke near midnight to check, and were finally called at 0400 for a 0500 start; each had built up a sleep debt of 2 to 3 hours. The Transportation Safety Board of Canada could not establish whether the sleep debt affected the crew's decisions, but found as a risk that unpredictable call times can stop crews getting restorative sleep and increase the risk of fatigue. No one was injured.

    A long-haul truck driver on a 28-hour run drove into stopped traffic on a major urban highway, causing an 11-vehicle pile-up that killed four people. The court found he had slept no more than about two hours after 13.5 hours of driving, had falsified his logbook to hide the missing rest, and was either distracted or falling asleep. He was convicted of criminal negligence causing death and jailed for eight years; the judge said a reasonable commercial truck driver would never have taken these risks.

    A track maintenance crew from a national freight railway drove a hi-rail vehicle onto the main line without authority and travelled about 8 miles before a freight train struck it; the two workers got out just in time. The Transportation Safety Board of Canada found the foreman's fatigue, influenced by two mild sleep disorders (obstructive sleep apnea and periodic limb movement disorder, diagnosed only after the accident), a circadian low and a demanding schedule, contributed to the error. It warned that track workers in safety-critical roles are not subject to enhanced medical requirements, so sleep disorders can go undetected.

    • 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.

    • Juridique

    A truck driver for a trucking company admitted working for other carriers, driving 85 to 95 hours a week and keeping two logbooks, and was dismissed in 2016. The arbitrator upheld the dismissal, finding that repeatedly and substantially exceeding the 70-hour weekly driving limit over many weeks was a serious fault, aggravated by the false logbooks and lies to the employer. The arbitrator rejected the argument that sleeping well, taking breaks and eating well reduced the risk, finding that driver fatigue is a biological state that cannot be controlled and that repeated excess hours build a sleep debt.

    A national railway's conductor on a train carrying special dangerous goods failed to warn the engineer that the train was traveling at 62 mph through a 35 mph restriction. He said he had been on the job for about 18 hours and that the limit slipped his mind through fatigue. The arbitrator refused to treat fatigue as a mitigating factor because the conductor had been able to book up to eight hours' rest before taking the assignment and chose not to, so his fatigue was his own decision. The 20 demerit marks were upheld.

    A national railway's locomotive engineer placed a low-power, non-turbocharged locomotive on line with high-power units, contrary to the railway's operating instructions, and the train set fires along the line that firefighters had to put out. He was dismissed for accumulating demerits. The arbitrator found discipline was warranted but counted the engineer's sleep apnea, which had caused him fatigue during 2015 and probably affected his work, among the reasons discharge was too severe, while stressing that employees are responsible for making sure they are fit to work. He was reinstated on a last-chance basis, demoted from locomotive engineer.

    • Juridique

    A national railway's locomotive engineer was found asleep in his stationary locomotive at about 7:25am, at the end of a night shift in which the crew had worked through their lunch break to service a customer. Finding him asleep led the railway to pull the locomotive's event recorder data, which showed repeated speeding on the two previous night shifts. The arbitrator held that the extra scrutiny was justified because it was reasonable to ask whether the engineer was fatigued, and said the sleeping on its own might have warranted a lesser penalty. The dismissal was upheld because of the speeding and the engineer's prior discipline for a very similar offence.

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.

    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.

    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.

On the run back to port the skipper handed the watch to the deckhand, and the vessel ran aground much closer to shore than intended. The Transportation Safety Board found that fatigue, made worse by the work/rest schedule, harmed the crew's performance, and that the deckhand probably fell asleep without meaning to. The vessel was declared a constructive total loss.

    Scallop deckhands on 9-on, 3-off rotation slept at most 18 hours in 72; fatigued decision ends in crushed foot

    • Sécurité

    After three days on a nine-hours-on, three-hours-off rotation, the deckhands on a scallop dragger had slept at most 18 hours in the previous 72. While the scallop rake was being hauled in, one deckhand tried to climb over the unguarded winch to reach its controls, slipped, and his foot was drawn onto the drum and crushed. The Transportation Safety Board found that the work/rest schedule most probably caused fatigue in the deckhands and affected their ability to make reasoned decisions.

    Lone iron-ore railway engineer with 13 hours' sleep in 48 passes signal and rear-ends ore-line train

    • Sécurité

    An iron-ore railway's freight train, with a single crew member in the cab, ran past a governing signal and struck the rear of another train. The engineer had obtained about 13 hours of sleep in the 48 hours before the accident, partly in daytime, after a split schedule of calls. The TSB found that the possibility fatigue contributed to his decision not to comply with the signal could not be ignored.

    Ferry master on new 10-hour shifts with little time to sleep leaves wheelhouse unattended; unmoored ferry drifts 45 m off the terminal while loading

    • Sécurité

    While a passenger-car ferry was loading passengers and vehicles, the master left the wheelhouse unattended with the ferry unmoored; a steering override failed and the ferry moved about 45 m off the terminal before the mate regained control. Earlier that year the operator had cut three positions and lengthened shifts from 8 to 10 hours, so the master, who lived on the mainland, had to catch a 0100 ferry to start work at 0530. The Transportation Safety Board of Canada found his judgment may have been affected by an accumulated sleep deficit caused by the schedule change. No one was injured.

    Freight crew with 1 hour's sleep in 24 'impaired by fatigue' run stop signal in fog and hit oncoming train

    • Sécurité

    A national railway's freight train passed a stop signal in dense fog and struck another train; all four crew members were slightly hurt jumping clear. The engineer had about one hour of sleep in the previous 24 hours and the conductor none, although both complied with the hours-of-service rules. The TSB found the crew was impaired by fatigue from excessive waking hours and that the rules did not address cumulative sleep debt.

    Engineer has probable sleep episode at 3:49 am; freight train runs into stationary train, two crew seriously hurt

    • Sécurité

    At 3:49 am a freight train ran past a restrictive signal at about 29 mph and struck the rear of a stationary train, pushing it into a third train; the two crew members of the moving train were seriously injured. The Transportation Safety Board of Canada found the locomotive engineer probably succumbed to fatigue and had a sleep episode, while the conductor was occupied with paperwork and did not provide backup. The board noted the crash happened in the 3 am to 5 am window of greatest sleepiness and that people are poor judges of their own fatigue.

    Freight crew awake since the previous morning speed through the early hours and rear-end a stationary freight train

    • Sécurité

    At about 0440 a national railway's freight train traveling far above the permitted speed ran into the rear of a stationary freight train, derailing two empty hopper cars and the front wheels of the lead locomotive. Both crew members told investigators they were tired: the locomotive engineer had not slept since 0700 and the conductor since 1000 the previous day. The Transportation Safety Board of Canada found that reduced alertness from disruption of the normal sleep cycle probably contributed to the inappropriately high speed. No one was injured.

    Medevac crew after long stand-by duty descend below approach altitude and hit beacon tower; 2 killed

    • Sécurité

    Just after midnight a twin turboprop returning from a medical evacuation flight descended below the mandatory altitude on approach to a northern regional airport, struck a navigation beacon tower and crashed, killing both pilots and seriously injuring the flight nurse. The Transportation Safety Board of Canada found the crew lost altitude awareness and listed probable pilot fatigue as a contributing factor. The first officer had been awake about 17 hours, had spent 180 hours on stand-by over the previous 14 days and had once been awake at least 36 hours straight in the days before.

    Airport firefighter refuses 34-hour triple shift; reviewing officer rules fatigue is not a 'danger' under federal law

    • Juridique

    A federal airport firefighter refused a request to work a triple shift that would have kept him on duty for 34 consecutive hours. A safety officer agreed there was a risk of fatigue affecting performance and safety awareness, and directed the employer to act. On review, the Regional Safety Officer accepted that fatigue may affect performance but held that fatigue was not a 'danger' as federal workplace safety law then defined it, and rescinded the direction. He warned that, given the right conditions, excessive hours would likely become a safety issue, and invited the employer to resolve the problem by consulting the safety and health committee.

    Pilot on duty 22 hours without restorative sleep on third straight assignment; bulk carrier strikes moored tanker

    • Sécurité

    In the end-of-season rush before the shipping season closed, a marine pilot took a third continuous assignment after two trans-lake trips instead of the required 12-hour rest. Berthing a bulk carrier in strong stern winds, he failed to stop the ship in time and it struck a moored tanker and the barge alongside. The Transportation Safety Board found that he had been on duty about 22 hours without restorative sleep, which probably impaired his judgment, and recommended that mandatory rest be enforced in assigning pilots.

    • Sécurité

    On the second day of the lobster season, the four-person crew of a small wooden lobster boat had been up since about 04:30 and had spent about 11 hours hauling, re-baiting and re-setting traps. Heading into harbour after dark, the operator made a navigational error and the boat grounded on a ledge. The Transportation Safety Board found that his performance was impaired by his poor health and by fatigue from the work. The operator, who was not wearing a flotation device, drowned.

    • Sécurité

    At about 7:00 am a fully loaded bulk carrier touched bottom on the side of the channel in a stretch of river rapids while under the conduct of a river pilot. The Transportation Safety Board of Canada found the pilot was tired at the start of the assignment despite more than two days off, that his sleep habits during rest periods did not support his performance, and that he was asleep at the moment of bottom contact. It also found the pilotage authority had no guidance or education for pilots on fatigue and irregular schedules.

    Supreme Court holds mine worker who kept driving while sleepy fully liable for supervisor's death

    • Sécurité
    • Juridique

    After a 12-hour shift at a mine development and a night out, a mine worker drove his supervisor home in the early hours, felt sleepy and wanted to stop but dozed off before he could, and the car hit a culvert, killing his passenger. The lower courts dismissed the family's claim on the basis the passenger had accepted the risk. The Supreme Court of Canada reversed this, holding that knowingly continuing to drive while sleepy was conduct a passenger could not reasonably foresee, so the passenger bore no blame.
