Five days ago officials from the NASCAR race warned fans who were traveling with a recreational vehicle (RV) about the dangers of carbon monoxide poisoning. A local health department in Indiana was also at Indianapolis Motor Speedway handing out information on carbon monoxide poisoning.

This warning to fans came in response to the tragic death of a 43-year-old man Michael Thies of Ruma, IL who suffered from carbon monoxide exposure and whose three family members were hospitalized from carbon monoxide fumes. The carbon monoxide is believed to have entered their RV from the exhaust of other nearby RVs.

Since summer has arrived more people are using their RVs to go to concerts, camp sites and sporting events. RVs are popular for traveling because they have beds, kitchens, refrigerators and small bathrooms. With these pleasures comes the responsibility of knowing the potential risk of carbon monoxide exposure.

Traditionally, winter is when carbon monoxide problems are most prevalent, however, this spring and summer have been particularly bad for such seasons.

It is important to know that there are several steps that RV users should take to ensure their safety. In our next blog, we will discuss the steps that RV users should consider to ensure that they are preventing carbon monoxide exposure.

Just when you thought it was safe to go back in the water… Not the water, but today’s news reports highlight another springtime hazard, construction sites. According to WHDH news in Boston, a construction worker was overcome today from what was thought to be carbon monoxide poisoning. Latest reports are dismissing the threat of carbon monoxide, but the risk factors could certainly exist. For the complete story, click here.

In this incident, the workers was working on a two mile long tunnel. Thus, the threat for a poorly ventilated carbon monoxide producing machine exists. What if there was no engine? Well, the human body is such a machine too.

It is probably just the perception from what makes the national news, but Pennsylvania seems to be the hardest hit this winter for Carbon Monoxide poisoning. The latest story to make news on Carbon monoxide exposure takes place in Altoona, PA, where a family of 5 was treated for exposure. The family was exposed to a CO level of 500 ppm, as opposed to what is considered a safe level of 9 ppm. That is more than 50 times a safe level. For more on this story, click here.

One of the disturbing parts to the story is that the the carbon monoxide levels were so high, that the smoke detectors were going off. Smoke detectors are not designed to detect even lethal levels of carbon monoxide, as it is not have the type of substance that leaves a tangible particulate in the air, which is what sets off smoke detectors.

Again, as always, I would remind everyone that a clean bill of health from hospital officials on the day of exposure, does not assure that there may not be long term health consequences. This is especially true with small children and older people. This family had a three year old and a two year old. Carbon monoxide exposure can cause a delay neurological symptoms DNS, which can appear 2 to 40 days after the exposure. For more information on DNS, click here.

As all eyes in the political spectrum turned to Ohio, and the plight of Youngstown is on every politician’s tongue, a man from nearby Vienna, Ohio quietly dies from carbon monoxide poisoning. In the wake of his death, paramedics put out a call for increased use of CO detectors.

The victim in this case was an aging man. The culprit an aging furnace. The combination, which happens so often with our elderly, is potentially lethal. The older the furnace, the more likely there could be a problem. The older the person, the more likely that where CO typically strikes first, the heart, will be adversely affected.

Check on your parents, check on your shut in friends. See to it that they have CO detectors, and make sure that they have had periodic maintenance on their furnaces.

It is winter, below zero here in Wisconsin this week, and I am warning about boating and carbon monoxide? As I joked to a friend who asked me about sailing – the water is a little hard right now.

Still, the carbon monoxide story of the day is a Washington Supreme Court Decision where a young woman died from carbon monoxide poisoning from swimming near the back of a boat: From that published case:



MADSEN, J. — Jay Colbert’s daughter, Denise Colbert, drowned after inhaling carbon monoxide fumes while hanging onto a motorboat as it was moving.


According to Mr. Colbert, at about 3:00 a.m. on August 3, 2003, he and hiwife Kelly were awakened by a telephone call from Kyle Swanson, the boyfriend of Mr. Colbert’s daughter, Denise. Mr. Swanson was quite upset. He told them
that Denise had disappeared from the back of a boat at Lake Tapps and a search was taking place for her. At about 1:30 a.m. Denise Colbert and others had gone for a boat ride aboard Marc Jacobi’s boat. Ms. Colbert and a friend were in the water holding on to the swimmers platform at the rear of the boat as it headed toward shore.1 After an hour and a half in the water, they decided to go swimming, and, as her friend stated, “[a]ll of a sudden she was gone. We were just swimming, and then she went under. There wasn’t a struggle or anything.”

Neither wore a life jacket. There was a placard on the stern prohibiting people from being on or near the swim platform when the engine was running, but Mr. Jacobi did not take steps to move Ms. Colbert and her friend. Mr. Swanson and others searched for Denise and Mr. Jacobi called 911; the call was received at 2:58 a.m.

A short time later Kyle Swanson called Mr. Colbert who took his other children to a neighbor’s house and then drove to the lake, about five minutes from their home. When he arrived, police cars, ambulances, and the fire department were at the scene. Mr. Colbert saw lights flashing from a boat on the water and knew the search for his daughter was underway. He drove to a friend’s house on the lake and watched the rescue operation from the friend’s dock. He hoped Denise would be found alive because Denise was an outstanding athlete with stamina and endurance, and she was a strong swimmer. Police Chaplain Arthur Sphar traveled back and forth between the rescue site and the dock to update Mr. Colbert about the search.

At some point after 6:00 a.m. rescuers found Denise’s body. Sphar relayed this to Mr. Colbert. About 10 minutes later Mr. Colbert saw a buoy pop to the lake’s surface. Because he could hear the dialogue from rescue workers on the
lake he knew what this meant — it was tied to Denise’s body. Mr. Colbert watched rescue boats move alongside the buoy. He saw Denise’s body pulled over the side of a boat by her arm. He averred that he could see rescue workers move Denise’s body once it was on the boat from about 100 yards away on the dock from which he watched. Mr. Colbert explains it was light enough that he could see this activity. Mr. Colbert saw an ambulance by the water, watched the police bring a
stretcher, put a sheet over Denise’s body, and take her away. He testified at a deposition that he was able to recognize the body as Denise’s. Chaplain Sphar said they could see a body being pulled from the lake, but added it was not
possible to see identifying detail from the dock. Denise had died about three hours before her body was recovered from the water. The cause of Ms. Colbert’s death was “drowning” with “ethanol toxicity” and “carbon monoxide” noted as significant. Her blood alcohol level was 0.12 g/100 ml.

Editors Note: The claim with respect to the death of the daughter was not at issue in the Appellate court decision. The disposition of the issues that were before the court in this decision were that the claims of the father for negligent infliction of emotional distress were dismissed, essentially because he was not at the scene at the time his daughter drowned.

Why did this drowning happen? Why did a strong swimmer drown within a few feet of safety? Why would a BAC of .12 cause such a result?

This happened for the same reason that almost all of the other cases discussed on this blog occurred: because Denise was in the wake of the exhaust of an engine, an engine that was spewing carbon monoxide fumes. Boating accidents are a surprisingly large segment of the carbon monoxide deaths. Boats are clearly one of the largest risk factors for carbon monoxide poisoning outside of the winter heating season. Manufacturers of boats put swim platforms on the back of boats, the same part of the boat such manufacturers funnel the engine exhaust. If people swim off the the swim platform, when the engine is running, they are a serious risk of carbon monoxide exposure. Unlike on land, where a moment of unconsciousness still leaves a chance of rescue, when swimming it can quickly turn deadly.

Is a mere warning about the risk enough? We think not. Swim platforms should no more be put where exhaust is vented, than boiler exhaust should be vented into swimming pools, another major CO risk factor. When swimming and CO mix, there is no margin for error.

This winter of 2008, there have been two well publicized mass shootings in my part time home state of Illinois, and many more mass killings from Carbon Monoxide. Even the election cycle news had to take a pause for the Northern Illinois tragedy. Nary a peep, except in the local media, about Carbon Monoxide’s rampages.
The first string of cases, was so predictable, I almost blame myself for not having found a bigger mountain top to have raised my cry of alarm: household generators. Any time there is a flame, and it is in an unventilated place, there will be a risk of CO exposure. Well the last few weeks has seen many storms. With storms, comes power outages. With power outages, comes the use of portable electric generators. My father spent his life designing such generators. Electric generators, when used properly, should not be a serious risk. But they were never intended to be set up in the kitchen, to operate the microwave.
More severe weather is sweeping across the nation this week. I fear that will be more power outages, more death from this silent killer. If you are in the business of selling portable generators, I believe you must include a CO detector with each purchase. That should be the law. I am sure the good businessmen who sell them warn people, but you can buy the little portable units almost anywhere now, and the corporate executives at Home Depot or Walmart, ought to just package the CO detector right with the product.
For more information on the dangers of portable generators, click here:
Here are the basic rules to avoid CO exposure when using a portable generator:
Always use generators outdoors.
Keep generator exhaust away from air that flows into a building. But also make sure it is away from windows, doore and vents. The venting part can be critical. Many of the tragic stories we have heard this winter was from indirect exposure because an engine source (like a generator) was too close to an air intake vent.
Garages, basements, crawl spaces, are not OUTDOORS.
Follow manufacturer’s instructions. This presumes you can still find the instructions. Hopefully they are printed right on the generator itself. If not, look them up online. Keep in mind that exhaust that can get into your living area can kill you.
Use CO detectors, and make sure they are working, that the batteries are replaced when needed. Remember that smoke detectors, are not CO detectors. You can have CO exposure with no smell of smoke and without a smoke detector going off.

The temperature is plummeting in the upper midwest, and the number of carbon monoxide poisoning cases is skyrocketing. This time it was Libertyville, IL. One man dead. The culprit, a malfunctioning hot water boiler for a car wash, in an enclosed space. That is a lethal combinations: a stressed boiler, a small room. No carbon monoxide detector installed. For complete details see,li-pjohnson-012908-s1.article

In theory, all fires (and a boiler, a furnace, a hot water heater, a fireplace, an engine are all fires) should occur in the open air where all fumes, including carbon monoxide will be dispersed below critical levels. Of course, the practicalities of civilized society is to bring the comforts of fire, indoors. Thus, comes the science and engineering of assuring complete combustion, which eliminates the risk of CO creation, and the science and engineering of complete ventilation of the exhaust of our controlled fires. But when science and engineering get translated into actual products and buildings, that must be designed, produced and maintained, there is always a risk of a break down, and the poison gas killing.

Engineers must always be on the watch for modifications of their designs and products, which could turn a well thought out design deadly. Maintenance people must always keep in mind the deadly nature of fire risk. Human occupants, must always remember to make sure their are carbon monoxide detectors to immediately warn of danger.

CARBON MONOXIDE POISONING SHOULD NEVER HAPPEN. SOMEONE WAS NEGLIGENT WHEN IT DID. Landlords, building owners must install carbon monoxide protectors to make sure that when all else fails, the potential victims of carbon monoxide, can get out in time.

Two more days, two more dead, and one in critical condition: The bodies of two Chickasaw, Alabama residents were removed from a home after apparently being poisoned by carbon monoxide. Click here for the breaking news.

It is three days since my last rant about hotels and carbon monoxide detectors, and once again 17 more people are hospitalized with dangerous carbon monoxide levels at a hotel. A hotel which is part of a national chain, a chain that does not require carbon monoxide detectors in each room. Comfort Suites. But this time it wasn’t comfort, it was nausea, headache and breathing problems that warned guests to call for help. Thank god they did. Click here for the excellent TV new story on this event in Jeffersontown, KY.

How can the hotel industry continue to ignore this risk? Do they breath a collective sigh of relief when no one, or as in the case of the Allentown, PA tragedy, only one person dies? CARBON MONOXIDE DETECTORS SHOULD BE MANDATORY IN ALL GUEST ROOMS. In Allentown, fire officials said a “tarp on the south side of the building likely forced the carbon monoxide from the hotel’s hot water heaters and recirculating the poisonous gas into the first-floor rooms and basement of the hotel.” See news story at

The hotel industry is a ripe place for CO poisoning, especially since when something goes wrong, so many are at risk. 17 people in Jeffersontown,KY, ten people in Allentown, PA, including one fatality. Click here for information on hotel exposures.

Even the hotel industries trade association acknowledges the risks, but nothing is done. The argument is that it would cost $100 million dollars to put detectors in each room in the United States. The lawsuits could add up to more, not to mention the cost in human lives. Click here for information on what states have regulations with respect to CO detectors in hotels.

Again, we remind everyone that a discharge with a clean bill of health does not guard against future problems, because of the delayed neurological symptoms that can occur. Click here for more information on DNS.

It has been a few days since our last blog and two more news stories have hit the national news about carbon monoxide poisoning. The first involved what seems to be good news, the second tragedy. Both may have far more tragic results than appears at present. The good news story involves a family of six in Anchorage, Alaska, who hit a snow bank when the driver succumbed to carbon monoxide poisoning. All lived. The tragic story involves a case of hotel negligence in Allentown, PA where one died and nine were sickened by carbon monoxide exposure.

While it doesn’t now appear to be what happened here, the Anchorage story highlights a serious risk this time of year: keeping a car running when it isn’t moving in hopes of staying warm. Any time car exhaust is not properly vented, there is some risk of carbon monoxide exposure. Of course, if you are sitting in a car in severe cold, the need may exist to keep the engine running to avoid freezing to death. But if something could obstruct the tailpipe, such as the snow, the moderate risk of danger and could become potentially catastrophic. Click here for the latest on the Anchorage story.

The Allentown, Pennsylvania story is all too familiar. A hotel does something stupid with the maintenance or design of their HVAC system, fumes go the wrong place, and a building full of people are at risk. In this case, workers doing construction on the outside of the hotel had erected a plastic tent-like canopy near the spot where the heaters were vented.

Making the hotel exposure cases even more outrageous, hotels refuse to put carbon monoxide protectors in each room. Only four states currently require carbon monoxide detectors in hotels, and none in each room. A recent study showed that only 11% of hotel chains that had had a carbon monoxide poisoning incident, had put in CO detectors, in each room, AFTER THE EXPOSURE. Such foolish risking of human lives must stop.

Perhaps even more troubling about these two incidents, is that the good fortune of the 15 survivors, may be an illusion. Carbon monoxide poisoning comes with it the risk of something called Delayed Neurological Sequelae, or DNS. Despite the apparent full recovery at the time of discharge from the hospital, the CO gases continue to attack the brain. Behavioral and neurologic deficits can arise or worsen two to 40 days after the exposure. Often times a patient is discharged from the hospital after initial evaluation, to have a severe relapse of symptoms, from this escalating pathology. The toxic effects of CO poisoning continue to attack the neurological system and particularly the brain, for many weeks after the initial exposure. This syndrome can materialize as almost any neurological or behavioral symptom, including memory loss, confusion, seizures, urinary incontinence, loss of bowel function, disorientation, hallucinations, psychosis and balance and dizziness. Click here for more information on DNS.

We don’t know what discharge warnings were given to these 15 individuals, but in our opinion, they should be required to follow up periodically with experts in CO exposure and have a repeat MRI done, at least once, to see if they have any signs of DNS. This is particularly true if the CO exposure caused a loss of consciousness, which it appeared to do in each case. As said in the Anchorage Daily New Story: “When officers arrived, the six occupants were either unconscious or unresponsive.” That is not the time to treat at the scene and send on their way. It is time to begin a careful monitoring to fully assess and possibly head off, the severe neurological attack that may lie in wait.
