What are the signs of carbon monoxide poisoning in the home. How can you protect your family from CO exposure. Where does carbon monoxide come from in residential settings. What steps should you take to prevent CO buildup indoors.

Understanding Carbon Monoxide: The Silent Killer

Carbon monoxide (CO) is an insidious threat lurking in many homes. This colorless, odorless gas is produced by the incomplete combustion of fuels and can quickly build up to dangerous levels indoors. When inhaled, CO molecules displace oxygen in the bloodstream, leading to potentially fatal poisoning.

The Centers for Disease Control and Prevention (CDC) estimates that approximately 400 people die from unintentional CO exposure in the United States annually. In Minnesota alone, an average of 14 people succumb to CO poisoning each year, with around 300 individuals requiring emergency treatment for exposure symptoms.

Why is carbon monoxide so dangerous?

• It’s impossible to detect with human senses
• Symptoms mimic common illnesses like the flu
• It can reach lethal concentrations before victims realize there’s a problem
• Exposure can cause rapid unconsciousness, preventing escape

Common Sources of Carbon Monoxide in Homes

CO is produced whenever fuel is burned. Homes with fuel-burning appliances or attached garages are at higher risk for CO problems. Understanding potential sources is crucial for prevention.

Which household items can produce carbon monoxide?

• Furnaces and boilers
• Gas stoves and ovens
• Water heaters
• Fireplaces (gas and wood-burning)
• Clothes dryers
• Motor vehicles
• Portable generators
• Grills and outdoor cooking equipment
• Power tools and lawn equipment
• Wood stoves
• Tobacco smoke

Recognizing the Symptoms of CO Poisoning

Carbon monoxide poisoning can be challenging to identify because its initial symptoms closely resemble those of the flu. This similarity often leads people to ignore early warning signs, potentially with dire consequences.

What are the early signs of carbon monoxide exposure?

• Mild headache
• Shortness of breath
• Nausea
• Dizziness
• Fatigue

As exposure continues or concentrations increase, symptoms may progress to:

• Severe headaches
• Confusion
• Vomiting
• Loss of muscle coordination
• Loss of consciousness

It’s crucial to recognize that CO poisoning can affect people differently. Factors such as age, overall health, and the concentration of CO all play a role in how quickly symptoms develop and their severity.

Protecting Your Family: CO Prevention Strategies

While carbon monoxide poses a serious threat, there are several effective ways to safeguard your home and loved ones from exposure.

How can you prevent carbon monoxide buildup in your home?

1. Install CO alarms on every level of your home, including outside sleeping areas
2. Properly maintain and vent all fuel-burning appliances
3. Have heating systems inspected annually by a qualified professional
4. Never use outdoor cooking or heating equipment inside
5. Avoid idling vehicles in attached garages
6. Ensure proper ventilation when using fireplaces or wood stoves
7. Clear snow and debris from exterior vents and chimneys

The Importance of Carbon Monoxide Alarms

Carbon monoxide alarms are a critical line of defense against this invisible threat. These devices continuously monitor the air for CO and sound an alarm when dangerous levels are detected, providing crucial early warning.

Where should CO alarms be installed in a home?

• On every level of the home
• Outside all sleeping areas
• Near attached garages
• In or near rooms with fuel-burning appliances

It’s important to note that CO alarms have a limited lifespan, typically 5-7 years. Check the manufacturer’s instructions for your specific model and replace units as recommended.

Carbon Monoxide Risks in Recreational Settings

CO poisoning isn’t limited to the home environment. Many popular outdoor activities can pose unexpected carbon monoxide risks if proper precautions aren’t taken.

Which recreational activities carry CO exposure risks?

• Camping
• Fishing (particularly ice fishing)
• Hunting
• Boating

To stay safe during these activities:

• Never use camp stoves, lanterns, or portable heaters inside tents, RVs, or cabins
• Ensure proper ventilation in ice fishing houses and hunting blinds
• Keep portable generators away from doors and windows
• Install CO alarms in boat cabins
• Be aware of exhaust from neighboring boats when docked

Understanding CO Concentrations and Health Effects

The severity of carbon monoxide poisoning depends on both the concentration of CO in the air and the duration of exposure. While outdoor CO levels typically range from 0.03 to 2.5 parts per million (ppm) in urban areas, indoor concentrations can quickly reach dangerous levels if there’s a problem.

At what CO levels do health effects occur?

• 35 ppm: Maximum allowable workplace exposure for 8 hours (OSHA standard)
• 50 ppm: Mild headache, fatigue, and nausea after 8 hours of exposure
• 200 ppm: Dizziness, nausea, and fatigue within 2-3 hours
• 400 ppm: Life-threatening after 3 hours
• 1,600 ppm: Nausea within 20 minutes, death within 1 hour
• 12,800 ppm: Unconsciousness after 2-3 breaths, death within 3 minutes

It’s important to remember that these are general guidelines, and individual reactions can vary. The elderly, young children, and those with pre-existing health conditions may be more susceptible to CO’s effects at lower concentrations.

Identifying Potential CO Problems in Your Home

While carbon monoxide itself is undetectable without specialized equipment, there are often signs that can indicate a potential CO problem in your home. Being aware of these warning signs can help you take action before a dangerous situation develops.

What are visual indicators of possible CO issues?

• Sooty or brownish-yellow stains around fuel-burning appliances
• Fallen soot in fireplaces
• Lack of an upward draft in chimneys
• Excessive moisture on windows, walls, or cold surfaces
• Rusting on flue pipes or appliance jacks
• Orange or yellow flames in gas appliances (should be blue)
• Pilot lights that frequently blow out

If you notice any of these signs, it’s crucial to have your appliances and heating systems inspected by a qualified professional as soon as possible. Don’t wait for your CO alarm to sound before taking action.

Emergency Response to CO Alarms and Suspected Poisoning

Knowing how to respond quickly and appropriately in a carbon monoxide emergency can save lives. It’s essential to have a plan in place and ensure all household members understand what to do if a CO alarm sounds or if poisoning is suspected.

What steps should you take if your CO alarm goes off?

1. Immediately evacuate all people and pets from the home
2. Call emergency services (911) from outside the building
3. Do not re-enter the home until emergency responders give the all-clear
4. Seek medical attention if anyone is experiencing symptoms of CO poisoning
5. Have a qualified technician inspect your fuel-burning appliances and chimneys

Remember, even if symptoms improve upon leaving the affected area, it’s still important to get medical evaluation. CO poisoning can have delayed or long-term effects that may not be immediately apparent.

How is carbon monoxide poisoning treated?

Treatment for CO poisoning typically involves breathing pure oxygen to help the body eliminate CO and replenish oxygen levels in the blood. In severe cases, hyperbaric oxygen therapy may be used, where the patient breathes 100% oxygen in a pressurized chamber to accelerate the removal of CO from the body.

Legal Requirements and Recommendations for CO Safety

Many jurisdictions have implemented laws and regulations regarding carbon monoxide safety in residential settings. While specifics may vary by location, understanding these requirements can help ensure your home meets or exceeds safety standards.

What are common CO safety regulations for homes?

• Mandatory CO alarms in all residential dwellings
• Required installation of CO alarms in new construction
• Specific placement requirements for CO alarms
• Regular inspections of fuel-burning appliances in rental properties
• Disclosure of CO risks and presence of alarms in real estate transactions

Beyond legal requirements, many safety organizations provide additional recommendations to enhance CO protection:

• Install CO alarms that meet UL 2034 or CSA 6.19 standards
• Choose alarms with digital displays to monitor CO levels
• Opt for combination smoke/CO alarms for comprehensive protection
• Consider interconnected alarm systems for whole-house alerts
• Develop and practice a home evacuation plan

By combining legal compliance with best practices, you can create a comprehensive CO safety strategy for your home and family.

Carbon Monoxide (CO) Poisoning in Your Home

Carbon Monoxide: Preventing carbon monoxide poisoning in your home (PDF)

Carbon monoxide (CO) is an odorless, colorless gas formed by the incomplete combustion of fuels. When people are exposed to CO gas, the CO molecules will displace the oxygen in their bodies and lead to poisoning.

The Problem with CO

Since CO has no odor, color or taste, it cannot be detected by our senses. This means that dangerous concentrations of the gas can build up indoors and humans have no way to detect the problem until they become ill. Furthermore, when people become sick the symptoms are similar to the flu, which can cause victims to ignore the early signs of CO poisoning.

The CDC estimates that approximately 400 people die from unintentional CO exposure in the United States every year. Data specific to Minnesota show that an average of 14 people die due to unintentional CO poisoning each year. Approximately 300 people visit emergency department each year for treatment of symptoms linked to unintentional CO exposure. For more information Carbon Monoxide Data Portal.

The good news is that carbon monoxide poisoning can be prevented with simple actions such as installing a CO alarm and maintaining fuel burning appliances.

Carbon Monoxide Sources in the Home

CO is produced whenever a material burns. Homes with fuel-burning appliances or attached garages are more likely to have CO problems Common sources of CO in our homes include fuel-burning appliances and devices such as:

• Clothes dryers
• Water heaters
• Furnaces or boilers
• Fireplaces, both gas and wood burning
• Gas stoves and ovens
• Motor vehicles
• Grills, generators, power tools, lawn equipment
• Wood stoves
• Tobacco smoke

Typical Indoor CO Concentrations

Ideally, the level of CO indoors should be the same as CO concentrations outside. In the Minneapolis/St. Paul metro area, outdoor CO levels typically range from 0.03-2.5 parts per million (ppm) averaged over an 8-hour period. These levels are well below the federal standard of 9 ppm for CO in outdoor air. In general, concentrations are lower in rural areas and higher in urban areas. Finding CO concentrations higher indoors than outdoors indicates a source of CO either inside or very close to your home.

CO and Recreation

There are a number of ways people can be exposed to high levels of carbon monoxide while participating in activities such as camping, fishing, hunting and boating.

• Items such as camp stoves, charcoal grills, fuel-burning lanterns and generators should never be used inside a tent, RV or cabin
• Do not place portable generators near open doors and windows
• Ice fishing houses that use heating equipment should have a working CO alarm installed and users should crack a window for additional ventilation
• Heating equipment in cabins and ice houses should be regularly inspected and be in good condition
• Boaters should be aware of exhaust area at the back of the boat and should tow passengers at least 20 feet from this area
• Be aware of exhaust from neighboring boats when parked near them
• Install a CO alarm in the cabin of boats

Protecting Your Family from CO Poisoning

1.

Properly vent and maintain fuel-burning appliances

It is important to know what appliances in your home are fuel-burning and make sure that they are maintained properly. All of these appliances should be vented to the outside. You should have your fuel-burning appliances (ex. furnace) checked by a qualified heating contractor every year to look for potential problems. It is also a good idea to know the signs of a potential CO problem:

• Streaks of soot around fuel-burning appliances, or fallen soot in a fireplace
• Absence of an upward draft in your chimney
• Excess moisture and condensation on windows, walls and cold surfaces
• Rusting on flue pipes or appliance jacks
• Orange or yellow flame in combustion appliances (the flame should be blue)
• Damaged or discolored bricks at the top of the chimney

Never use appliances intended for outdoor use inside. Examples include barbecue grills, camp stoves, portable generators or gas-powered lawn equipment. Do not use an oven to heat your home. Not only is it a fire risk, it is also a carbon monoxide hazard. Do not run or idle your vehicle in an attached garage. Instead, back your vehicle out right away. Check that your vehicle’s exhaust pipe is not blocked, for example, by snow during the winter.

2. Know the symptoms of CO poisoning

Identifying CO poisoning can be difficult because the symptoms are similar to the flu. CO is often called the “silent killer” because people will ignore early signs and eventually lose consciousness and be unable to escape to safety.

For most people, the first signs of exposure include mild headache and breathlessness with moderate exercise. Continued exposure can lead to more severe headaches, dizziness, fatigue and nausea. Eventually symptoms may progress to confusion, irritability, impaired judgment and coordination, and loss of consciousness.

You can tell the difference between CO poisoning and the flu with these clues:

• You feel better when you are away from home
• Everyone is the home is sick at the same time (the flu virus usually spreads from person to person)
• The family members most affected spend the most time in the house
• Indoor pets appear ill
• You don’t have a fever or body aches, and you don’t have swollen lymph nodes that are common with the flu and some other infections
• Symptoms appear or seem to get worse when using fuel-burning equipment

3.

Install and maintain CO alarms in your home

Minnesota state law (MN Statute 299F.50) requires that every home have at least one operational CO alarm within 10 feet of every room legally used for sleeping. All CO alarms should conform to the latest Underwriters Laboratory (UL) Standards. Please follow the manufacturer’s instructions for placement of your CO alarm, and take note of the suggested replacement date.

Frequently Asked Questions

Are some people at greater risk of CO poisoning?

Yes, some people are at a greater risk for CO poisoning. Those individuals include people with:

• Respiratory conditions, such as asthma or emphysema
• Cardiovascular disease
• Anemia or sickle cell anemia

Also, the elderly and young children are at a greater risk for CO poisoning than adults. Individuals engaging in strenuous activity have also been found to be at greater risk. Remember, ANYONE can become sick and die from CO poisoning when exposed to very high levels.

Can CO be a problem in the summer?

Yes. Although CO poisoning cases are higher during the winter months, there are situations where people can be exposed to high levels of CO during the summer. Vehicles including boats produce carbon monoxide. Devices such as camp stoves, barbecue grills and non-electric heaters are commonly used during recreational activities and also are sources of CO.

The CDC has noted that CO poisoning cases have resulted from the use of power generators during power outages. Portable generators are capable of producing more carbon monoxide than modern cars and can kill people in a short amount of time. It is recommended that users place generators at least 25 feet away from and downwind of a house. Be sure that there are no vents or openings near the generator that would allow exhaust to enter into your home.

How long do CO alarms last?

The typical lifespan of a CO alarm is between 5 and 7 years, but it varies by manufacturer. Consult the product packaging or manufacturer for a recommended replacement date.

What do I do when my CO alarm sounds?

Don’t ignore a CO alarm if it is sounding. If people in the home are exhibiting symptoms of CO poisoning, immediately leave the building and call your local fire department. In cases where residents are feeling fine, call your local gas utility company or a qualified technician to help identify the cause of the problem. 

Signs of a Carbon Monoxide Leak in Your Home

Jump to Sections

Carbon monoxide, or CO, is a colorless, tasteless gas produced by the incomplete burning of any carbon fuels, such as natural gas or liquified petroleum gas. Your heating equipment may give off trace amounts of this gas, but by design, it vents CO outside, where the gas doesn’t have the chance to build up in your home. However, if you have a carbon monoxide leak in your home, it could accumulate too quickly for your system to handle.

Also called the “silent killer,” carbon monoxide can lead to severe health damage without early detection. Prolonged exposure to CO can cause carbon monoxide poisoning, and while many patients fully recover, it can also cause permanent brain damage or death. How do you know if you have a carbon monoxide leak?

If you have questions or concerns about your home’s carbon monoxide detectors, contact us online or call us today at 781-595-0000 to talk with an expert!

What Does Carbon Monoxide Smell Like?

Can you smell carbon monoxide? By itself, carbon monoxide is odorless. While a CO buildup may feature accompanying exhaust gases that have a noticeable smell, you shouldn’t rely on the exhaust odor to detect carbon monoxide.

When you breathe in CO, it enters your bloodstream and inhibits your blood’s ability to carry oxygen. Because people cannot tell when they are inhaling this gas, accidental exposure to carbon monoxide accounts for over 400 deaths, 20,000 ER visits, and 4,000 hospitalizations yearly.

What Are Signs of Carbon Monoxide in Your Home?

Since carbon monoxide has no color, smell or taste, it is vital to learn how to spot the signs of potential leaks in your business or home. By learning how to check for a carbon monoxide leak, you can know when to seek help and stay safe.

• Yellow or orange flames coming out of your gas appliances instead of the usual blue flame
• Dark and sooty staining on or around gas appliances
• Pilot lights that frequently blow out
• Increased condensation on windows
• Solid fuel fires burn much slower than usual

Since carbon monoxide is so toxic, you and your family could be at risk of CO poisoning if you leave yourselves exposed to it for too long. Some resulting changes in your well-being mimic hangover symptoms and may also signify that you may have a carbon monoxide leak in your home.

• Headaches
• Dizziness
• Nausea
• Breathlessness and chest pains
• Fainting or collapsing

If you begin experiencing these signs, it is critical to open doors and windows, evacuate your home, turn off your gas appliances, get fresh air, call your doctor and contact a professional to find the source of your carbon monoxide leak.

How Can You Detect Carbon Monoxide?

While CO is entirely odorless, you can still detect it within your home. One straightforward solution is to get carbon monoxide detectors, which resemble smoke detectors and easily install anywhere around your home. Contrary to popular belief that carbon monoxide is heavier than air, CO monitors will be equally effective no matter where you choose to place them in a room.

CO monitors will sound an alarm when they detect traces of carbon monoxide in your home or business. It’s a best practice to place them in any room with a gas appliance, so you’ll need one in your kitchen if you have a gas stove, another near a gas water heater and so forth.

Some CO detectors also have select beeping functions to communicate with you. For example, a specific number of beeps within a given time frame could signal the need for new batteries or the presence of carbon monoxide in the air.

If you have gas appliances, it’s also crucial to schedule annual professional inspections. A trained technician who knows how to test for carbon monoxide can spot signs of potential leaks before they threaten your health and give you expert tips for preventing CO leaks in your home.

How to Prevent Carbon Monoxide Leaks

Now that you know what causes carbon monoxide leaks, we will look at some of the ways to stop them from occurring in your home or business. Other than scheduling preventive maintenance and service for your gas appliances, here are some excellent ways to prevent carbon monoxide leaks.

• Do not use portable flameless chemical heaters.
• Have your chimney inspected and cleaned annually. Chimney blockages can cause CO buildups.
• Never use temporary seals for a vent or pipe.
• Never use a gas range, dryer, or oven to heat a room.
• Never burn charcoal or use a portable grill indoors.
• Ensure your gas appliances vent correctly. Horizontal pipes prevent carbon monoxide from leaking in cases of incorrectly fitted joints.

While following these best practices can help you prevent carbon monoxide leaks, there are no guarantee leaks will not occur. Purchasing a carbon monoxide detector should still be your priority, as these are your family’s first line of defense against CO in the air.

Carbon monoxide, signs of poisoning, first aid

What is carbon monoxide, causes of poisoning

Carbon monoxide is a fast and general toxic poison. If its concentration in the air reaches 1.2% or more, then the death of the victim occurs within 3 minutes. The danger of carbon monoxide is as follows:

1. It has neither color nor smell – a person simply will not feel its presence in the room.
2. Able to penetrate soil layers, walls and any partitions.
3. Not absorbed by porous materials, so even conventional filtering gas masks do not protect against the toxic effects of carbon monoxide

Causes of carbon monoxide in the room

• Insufficient ventilation of the room (no triple air exchange). Most often this happens with weak draft in the ventilation ducts and with closed windows, transoms.
• Insufficient air is supplied to the gas burner (flame
  high, smoky) this happens when the burner combustion is not adjusted.
• Gas heaters and water heaters operate with unstable draft in the chimney or in the absence of it. Most often this happens when the chimney is not cleaned in a timely manner or foreign objects get into it (the chimney head is destroyed, an ice blockage has formed).

Signs of poisoning

First of all, this type of gas blocks the delivery of oxygen to organs and tissues – it is considered a blood poison, since erythrocytes are primarily affected. Normally, these blood cells carry oxygen to organs and systems with the help of hemoglobin, and when carbon monoxide enters the body, it binds to hemoglobin, forming carboxyhemoglobin, which is considered a compound that is detrimental to the whole organism. As a result, erythrocytes are not able to deliver oxygen to organs and tissues, the whole body experiences acute oxygen starvation (hypoxia).

To make a more convenient classification, experts divided the symptoms of carbon monoxide poisoning into three categories that can occur: mild, moderate and severe.

Mild effect:

• high blood pressure;
• headache;
• knocking in the temples;
• vomiting and nausea;
• dizziness and weakness;
• chest pain and dry cough;
• increased heart rate;
• tearfulness and possible auditory hallucinations.

Medium effect:

• partial or complete paralysis;
• increased tinnitus;
• drowsiness;

Severe degree of influence:

• muscle cramps;
• loss of consciousness;
• pupillary enlargement with minimal light reaction;
• uncontrolled bowel or bladder emptying;
• labored breathing;
• bluing of the facial skin.

All of these factors are the result of a dangerous carbon monoxide leak. And if you feel any of these symptoms, and there is a gasified source nearby, we strongly recommend that you leave the premises.

First aid for carbon monoxide poisoning

1. Call an ambulance
2. Quickly remove the victim from the carbon monoxide zone, provide fresh air (open windows, doors, etc.)
3. Give victim oxygen
4. Place a cold compress or ice pack on the head and chest
5. If the victim is unconscious, give ammonia to smell every five minutes

How to avoid carbon monoxide poisoning

In order to avoid carbon monoxide poisoning, it is necessary to monitor the condition of chimneys and ventilation ducts and clean them regularly.

When operating household gas appliances, it is important to check the presence of draft, if there is no draft, gas equipment cannot be operated.

first aid, signs, treatment, prevention at home

Signs of carbon monoxide poisoning

Carbon monoxide (CO) is released during incomplete combustion of fuel, as well as any other organic substances. This gas is formed as a result of combustion in conditions of oxygen deficiency. In the open air, carbon monoxide quickly dissipates, while in enclosed spaces, with oxygen deficiency, it can accumulate in large quantities.

The main danger of carbon monoxide is that through the lungs it enters the bloodstream, where it binds strongly to hemoglobin and prevents oxygen from binding to hemoglobin. This leads to oxygen starvation of tissues and organs.

Carbon monoxide is colorless and odorless and cannot be detected. The victim may not pay attention to the first signs of carbon monoxide poisoning – weakness, yawning, drowsiness. Weakness increases with increasing concentration of carbon monoxide. Against the background of weakness, you want to sleep, which can be very dangerous and lead to death.

Strongly connecting with hemoglobin, carbon monoxide causes hypoxia (oxygen starvation) of brain cells, as a result of which lethargy, drowsiness develops, which are accompanied by headache, nausea, and vomiting. Prolonged inhalation of carbon monoxide in some cases can lead to heart failure, myocardial infarction, stroke, and in severe poisoning, convulsions, coma and death.

First aid for carbon monoxide poisoning

It is very important to provide first aid to the victim in time. Required:

• immediately remove the victim from the room to fresh air, and if this is not possible, put on a gas mask or give an oxygen bag;
• facilitate breathing, if necessary, clear the airways of mucus, vomit, unfasten constricting clothing, lay on one side in order to prevent retraction of the tongue;
• stimulate breathing, give ammonia. Warm hands and feet at low temperatures.

It is important to call an ambulance immediately, even if you think the person is in a satisfactory condition. Timely medical assistance will prevent complications that may develop later.

In case of severe condition, it is necessary to independently carry out resuscitation measures – artificial respiration and chest compressions.

Immediately remove the victim from the room to fresh air, and if this is not possible, put on a gas mask or give an oxygen bag;

Facilitate breathing, if necessary, clear the airways of mucus, vomit, unfasten constricting clothing, lay on one side in order to prevent retraction of the tongue;

Stimulate breathing, give ammonia. Warm hands and feet at low temperatures.

Carbon monoxide poisoning treatments

Carbon monoxide poisoning in all cases requires urgent hospitalization. Already in stationary conditions, oxygen therapy is performed by supplying an oxygen mixture. In order to remove toxins from the body, the patient is prescribed intravenous infusions of special solutions.
