For some workers, going to work chronically fatigued might be more dangerous than being at work drunk, according to a sleep expert speaking at the IAM141 2017 Safety Conference this week.
Airline union activists, managers, and safety advocates learned a surprising fact this week. Working with chronic, accumulative fatigue is more dangerous than working while moderately intoxicated – a lot more dangerous.
Mike Harnett, a featured speaker at the Conference, knows just how harmful a lack of sleep can be. She is an expert on the subject of fatigue management and sleep deprivation, and her research on the topic has provided valuable guidance to groups and organizations such as NASA, airports, transportation companies and labor groups such as the IAM.
“BEING AWAKE IS NOT ENOUGH”
With news reports of baggage handlers falling asleep in the underbellies of the planes they are working, only to awaken after take-off, sleeplessness has already become a severe issue for air carriers. Airport workers need high levels of physical athleticism, mental focus, and situational awareness to do their jobs safely. And, when the safety of the flying public is also taken into account, the need to avoid the kinds of impairments that come with knocking back a few beers before work is a no-brainer.
Yet, unlike being a little tipsy at work, it can be hard for employers and even workers to wake up to the dangers of chronic sleep deprivation. Nevertheless, the problem should be taken seriously, according to Harnett. Especially in the case of airport workers, who are uniquely vulnerable to the damage that can be caused by the effects of fatigue.
“IMPAIRED IS IMPAIRED”
Meanwhile, the symptoms of sleep deprivation are almost identical to intoxication. Loss of situational awareness, underestimation of risk, hindered visual perception, and reduced reaction times are all symptomatic of both drunkenness and fatigue.
Peer-reviewed studies have consistently demonstrated that a person who has been awake for only 17 hours has the equivalent impairment of a person with a blood-alcohol level of .05%. (In many states, a blood-alcohol level of .08% is enough to result in a DUI arrest.) Those who have stayed awake from 5:00 AM to 2:00 in the morning without sleeping will have reached a .08% blood alcohol level of impairment, and those who have gone without rest for 24 hours can expect an equivalent impairment of .1%. ??“Impaired is impaired,” Mike Harnett told the crowd of some 120 union activists and company managers. “If you are impaired because you’re drunk, or if you have these same impairments due to fatigue, you are creating the same hazard.”
Fatigue is one of the most common causes of airline accidents, with most airport injuries happening early in the morning and late at night when workers are the most tired.
BETTER UNDERSTANDING IS NEEDED
Fixing the problem will require more than a nap. Harnett says that those suffering from chronic fatigue cannot accurately determine if they have reached a dangerous level of sleep deprivation. Even worse, the problem is rampant, with strong majorities of Americans completely unaware of the danger of chronic fatigue. Airport workers who must work sleep-defying shifts late at night or very early in the morning, and who get hit with mandatory overtime and inconsistent days off on a regular basis may be even more at risk than the overall population.
Harnett suggests that the solution to accidents caused by chronic fatigue will require a long-term partnership between workers and companies. Companies will need to begin understanding that fatigue can be a real threat and not merely a discipline issue. Company managers often think of sleep as a personal issue that shouldn’t be factored into the work environment. In many cases, travel times to and from work are not factored into the space between work shifts. At many airlines, workers are severely punished for napping at the workplace before or after shifts. These policies need to change, Harnett says.
But, a lot of the burden is going to fall on the shoulders of airline workers themselves. There are real dangers associated with chronic fatigue, and most of these problems can be solved with better sleep.

Fatigue is more than just a bad night’s sleep. Being in a chronic state of tiredness has adverse health effects from slow response times to increased vulnerability to disease. Employers can reduce the harm by creating a fatigue risk-management system.
Getting enough sleep is essential for our health, but it’s often easy to believe we can overcome fatigue with another cup of coffee or a splash of cold water to the face. In reality, the rise of digital technology and 24/7 workplaces is changing the way we work, and making it easier to work at any time of the day.
This comes with business benefits in terms of workplace productivity, flexible work schedules, and meeting growing consumer needs. But the flip side is that, according to a sleep review from Dalhousie University, only 26 percent of Canadians get a minimum seven hours of sleep per night. And an estimated 40 to 50 percent of workers are fatigued at work.
“Globally, fatigue has been identified as a contributory factor in many serious and fatal incidents spanning decades. It is having real impacts on workplace health and safety,” says Heather Kahle, a human factors specialist and ergonomist at WorkSafeBC. “Fatigue decreases one’s ability to perceive and process important information necessary for safety. It may also decrease one’s ability to adequately respond to workplace hazards.”
More than feeling drowsy or sleepy, fatigue is an acute or
chronic state of tiredness. Disruptions to our body’s natural circadian rhythms
— which affect our sleeping and waking cycles — from such things as shift work,
long shifts, and back-to-back shifts increase the risk
of workplace fatigue. If left unchecked, fatigue can contribute
to long-term health effects, such as a vulnerability to certain types of
cancers, heart disease, stroke, diabetes, dementia, and Alzheimer’s disease.
Putting workplace fatigue to bed WorkSafeBC held its inaugural Fatigue Risk Management Symposium on June 7, 2018, to raise awareness of the risks associated with fatigue in the workplace and the importance of addressing them. Nearly 200 professionals from a variety of industries heard from five leading experts on fatigue-related risk in the workplace.
Presentations and discussions covered topics ranging from
fatigue risk management to circadian rhythms and how fatigue influences workplace
performance. Presenter Mike Harnett, president of Solaris Fatigue Management,
emphasized why it’s important for employers to take an active role in
preventing fatigue. She notes that fatigue in the workplace only became part of
the broader risk assessment dialogue for employers in the past three to four
years, largely due to increased reporting on scientific findings that show fatigue
impairment is real. Before that, fatigue was often seen as an issue for workers,
not employers. Fatigue risk management is a shared responsibility. “We cannot
continue to blame the worker and classify the cause of incidents as ‘human
error.’” The challenge now, Harnett says, is to continue to raise the profile
of fatigue as a risk-management priority. “Management needs to see fatigue as a
business issue
and collect metrics to drive informed decision making,” says
Harnett. “Only through the collection of
objective data can management set targets that support KPIs [key performance
indicators]. As we often say in the safety world: What gets managed, gets
done.” Managing fatigue from the top down A fatigue risk-management system
(FRMS) is a highly useful framework employers can use to proactively identify
and evaluate hazards and risks that may result in harm or adverse outcomes. Critical
to this undertaking is establishing an integrated, consistent, and trustworthy
system-wide approach to identify, assess, and control for the risks that can
escalate in the presence of fatigue. Transparent reporting and evaluation
policies are also essential ingredients of a successful FRMS. “With fatigue
recognized as a key contributory factor in workplace health and safety, FRMS is
a solid framework used worldwide to measure, mitigate, and manage the risk of
fatigue,” says Kahle. “It can be used to set priorities and establish baseline
data to evaluate fatigue management strategies over time to ensure that
targets are being met and the appropriate interventions are
being used. “Employers will have fatigued workers in the workplace at some
point. It’s important to ask yourself if hazards in the workplace increase the
risk of harm or could lead to adverse safety outcomes when workers are
fatigued,” adds Kahle. “When workers miss changes or
important information in their environment because of fatigue, it affects
everything we do in the workplace. Addressing this can save businesses
countless dollars due to injury and lost productivity.” For more information
