This accident here was rather interesting...

2008 MBTA crash, Newton, Massachusetts; 1 killed

It wasn't a train accident, meaning mainline, and instead an LRV accident on the Green Line in Newton.

It was a new driver who initially was blamed for using a mobile phone. It was determined later that she was not using a phone and instead had suffered from micro-sleep incidents caused by sleep apnea.

A year later, however, there was another accident on the same line in Park Street station under ground. In this incident, the driver was found to be texting and rear-ended a stopped trolley. This caused substantial damage to the tunnel and station as well as the trolley. No one was killed, but there were a number of injuries.

And then again in 2012 was another accident on at Boylston Street.

In this incident the driver was fired because of disregard to the safety of the passengers. He had worked a second job and was not rested and had fallen asleep at the controls. He had a flawless safety record up until this point and was scheduled to receive a safety award!
 
[h=1]Insufficient Sleep Is a Public Health Problem[/h]
dssleep_456px.jpg
Continued public health surveillance of sleep quality, duration, behaviors, and disorders is needed to monitor sleep difficulties and their health impact.
Sleep is increasingly recognized as important to public health, with sleep insufficiency linked to motor vehicle crashes, industrial disasters, and medical and other occupational errors.[SUP]1[/SUP] Unintentionally falling asleep, nodding off while driving, and having difficulty performing daily tasks because of sleepiness all may contribute to these hazardous outcomes. Persons experiencing sleep insufficiency are also more likely to suffer from chronic diseases such as hypertension, diabetes, depression, and obesity, as well as from cancer, increased mortality, and reduced quality of life and productivity.[SUP]1[/SUP] Sleep insufficiency may be caused by broad scale societal factors such as round-the-clock access to technology and work schedules, but sleep disorders such as insomnia or obstructive sleep apnea also play an important role.[SUP]1[/SUP] An estimated 50-70 million US adults have sleep or wakefulness disorder[SUP]1[/SUP]. Notably, snoring is a major indicator of obstructive sleep apnea.

In recognition of the importance of sleep to the nation's health, CDC surveillance of sleep-related behaviors has increased in recent years. Additionally, the Institute of Medicine encouraged collaboration between CDC and the National Center on Sleep Disorders Research to support development and expansion of adequate surveillance of the U.S. population's sleep patterns and associated outcomes. Two new reports on the prevalence of unhealthy sleep behaviors and self-reported sleep-related difficulties among U.S. adults provide further evidence that insufficient sleep is an important public health concern.

[h=3]Sleep-Related Unhealthy Behaviors[/h] The Behavioral Risk Factor Surveillance System (BRFSS) survey included a core question regarding perceived insufficient rest or sleep in 2008 (included since 1995 on the Health Related Quality of Life module) and an optional module of four questions on sleep behavior in 2009. Data from the 2009 BRFSS Sleep module were used to assess the prevalence of unhealthy/sleep behaviors by selected sociodemographic factors and geographic variations in 12 states. The analysis [1.1 MB], determined that, among 74,571 adult respondents in 12 states, 35.3% reported <7 hours of sleep during a typical 24-hour period, 48.0% reported snoring, 37.9% reported unintentionally falling asleep during the day at least once in the preceding month, and 4.7% reported nodding off or falling asleep while driving at least once in the preceding month. This is the first CDC surveillance report to include estimates of drowsy driving and unintentionally falling asleep during the day. The National Department of Transportation estimates drowsy driving to be responsible for 1,550 fatalities and 40,000 nonfatal injuries annually in the United States.[SUP]2[/SUP]

[h=3]Self-reported Sleep-related Difficulties Among Adults[/h] The National Health and Nutrition Examination Survey (NHANES) introduced the Sleep Disorders Questionnaire in 2005 for participants 16 years of age and older. This analysis [PDF - 1.1MB] was conducted using data from the last two survey cycles (2005–2006 and 2007–2008) to include 10,896 respondents aged ≥20 years. A short sleep duration was found to be more common among adults ages 20–39 years (37.0%) or 40–59 years (40.3%) than among adults aged ≥60 years (32.0%), and among non-Hispanic blacks (53.0%) compared to non-Hispanic whites (34.5%), Mexican-Americans (35.2%), or those of other race/ethnicity (41.7%). Adults who reported sleeping less than the recommended 7–9 hours per night were more likely to have difficulty performing many daily tasks.

[h=3]How Much Sleep Do We Need? And How Much Sleep Are We Getting?[/h] How much sleep we need varies between individuals but generally changes as we age. The National Institutes of Health suggests that school-age children need at least 10 hours of sleep daily, teens need 9-10[SUP]5[/SUP] hours, and adults need 7-8 hours. According to data from the National Health Interview Survey, nearly 30% of adults reported an average of ≤6 hours of sleep per day in 2005-2007.[SUP]3[/SUP] In 2009, only 31% of high school students reported getting at least 8 hours of sleep on an average school night.[SUP]4[/SUP]
[h=3]Sleep Hygiene Tips[/h] The promotion of good sleep habits and regular sleep is known as sleep hygiene. The following sleep hygiene tips can be used to improve sleep.

  • Go to bed at the same time each night and rise at the same time each morning.
  • Avoid large meals before bedtime.
  • Avoid caffeine and alcohol close to bedtime.
  • Avoid nicotine.

John,

I posted article below, as I used to get made fun of when I would take a nap at break time, I had friends that would go party and such, wore themselves out to the point of falling asleep at the wheel, and in one case turning the auto upside down and broken arm, they had near accidents twice before from long hours of work. For me that little nap made all the difference my day, of course I know napping isn't as good as good sleep cycle but it helped me.

At one time I was working 17 hours a day, and it finally caught up with me and I realized even trying to macho it out was taking a heavy toll on the body.

I'm older and wiser now than young and reckless.......So I do talk to folks about required sleep and Sleep Apnea etc........It is a very real problem in the US where 20% of us do not get enough sleep......

I worked graveyard , or as some people would know it,, 3rd shift, it does weird things to the body as we are not Nocturnal in the true sense of the word although there are those of use that try to replicate that activity......LOL

https://en.wikipedia.org/wiki/Nocturnality

And it is very prevalent I would think in Airline, Shipping and other related crafts, to what degree I don't know.

I bid you a good day sir.
 
You've hit on some very important points, here Blue.

I worked a swing shift for years, meaning Wednesday through Sunday with Monday and Tuesday off. This was odd enough, but the hours were worse. Wednesday through Friday was 9:00 to 5:30, with Thursdays were later, sometimes a 2nd shift coverage. Saturday and Sunday were first shift coverage. Then when it came to vacations, I had to cover those too including the graveyard shift. I don't mind second shift and had worked that for years, but this crazy schedule was awful. Then it happened... A 2nd shift operator came in drunk a few too many times and was fired. I then covered his shift on Monday and Tuesday 2nd shift with my other hours for the rest of the week. I did this for about a year until a new worker was hired. In the end I quit due to the stress and getting sick.

Fast forward until a few years ago, and I too thought nothing of working a 17 hour day. I would go until I dropped, literally and then pick up where I left off. Those power naps helped during the day at lunch. A quick 15 minutes of shut eye charged the batteries as we say and I would continue.

Now with the onset of Early Onset PD, I fatigue rapidly and luckily I am no longer working. With PLMD or Periodic Limb Movement Disorder, dystonia, frequent bathroom disturbances, and in ability to roll over in bed, I don't sleep well.

So what happens? I nap and nap quite often including while driving in Trainz! I'll be going along fine then find myself closing my eyes more and more until I wake up too late to stop the train. Now this is a simulator and not the real world. I'm glad no one gets hurt because the worse could happen. It's a good thing I don't drive my car very far now, otherwise, that too would be horrid. I tend to stick to quick appointments or shopping, then come back home, take meds and nap.

I will say that naps are truly an under-estimated hobby which I think should be part of everyone's lifestyle. The world would not only be safer but also people would be less grumpy and less edgy from living on stimulants.

Hi everybody.
I have worked in industrial safety for close to thirty years with most of that period being involved with the British Road Haulage Industry (known as trucking in the United States).what is known as “involuntary sleep attacks” have over many years been the bane of the industry causing many accidents by way of drivers falling asleep at the wheel.

Undoubtedly having a minimum of eight hours sleep in any twenty four hours can be the greatest means of preventing the above attacks. However, for many years a condition known as narcolepsy can mean that even when a person has had a full period of eight hours sleep sudden and uncontrollable sleep attacks can still occur in persons with the condition.

Narcolepsy can go under several different names and within that have symptoms which vary in nature. However all can mean that a sufferer will suddenly lose function by way of dizziness, feeling drowsy, sudden sleep attack or full loss of consciousness. The attacks may only last for a few minutes or even a few seconds, but in the case of someone in control of a moving vehicle (especially a heavy commercial vehicle) the results can be devastating to all who may be involved.

In Britain the above condition(s) is a reportable disease meaning that a sufferer's condition must be reported to the driver licensing authority by that person's GP (Physician) in which case if the sufferer holds a vocational licence it is always suspended or permanently revoked. Along with the foregoing a person with such a condition would under the Health & Safety at Work Act (Employees Responsibilities Section) be under legal obligation to report his/her condition to their employer.

However, in the above many persons who have the symptoms of the condition ether do not recognize it as so, or do not declare the symptoms to anyone for fear of losing their employment. Hence the number of accidents caused by the disease has been very difficult to elevate as their is no workplace test that can be carried out as is the case for alcohol and drugs.

The above becomes even more complicated as in recent years it has become recognized that many people without any regular symptoms of narcolepsy can in various circumstances encounter sudden conditions of drowsiness even following a full period of rest and sleep. The Health and Safety Executive here in the UK are carrying out a full investigation into the circumstances of how the foregoing can occur and are requesting vocational drivers and heavy mobile equipment operators to forward their experiences of such attacks to them.

Many years ago before I became involved in industrial safety I was a heavy goods vehicle driver. Several times in those years I did experience sudden drowsiness while driving which could occur within a short period of commencing duty and after a good night's sleep. My experience was that this could occur before the onset of a cold or suchlike condition and before the main symptoms of the cold or other became apparent.

I have sent forward by way of a report my experiences to the HSE to help with their enquiries.

The is really amazing as I recall many years back someone describing similar symptoms, and I didn't realize till I read your msg here that this person must have had this problem, but I wasn't aware of this is what the condition was called nor how serious it could be, thanks for your contribution.....It's been very enlightening to me!
