Carbon Monoxide Detectors

Carbon monoxide (CO) is a dangerous gas without color or odor. It is produced when fuels like wood, charcoal, gasoline, natural gas, propane, oil, and methane do not burn completely. CO can be generated by things like space heaters, open flames, generators, water heaters, blocked chimneys, or vehicles left running in an enclosed space. While the risks of exposure are high and can be quite scary, protecting your family is straightforward with proper education, preparation, and maintenance.

Carbon Monoxide in Your Home

The primary sources of carbon monoxide in your home are heating and cooking equipment. Vehicles and home generators can also release dangerous levels of the gas, so exercise caution when operating them in garages or close to the home. 

Safeguarding your loved ones from the dangers of CO requires an understanding of its true dangers. Over 430 people in the United States die from accidental CO poisoning every year, and 50,000 visit the emergency room due to carbon monoxide poisoning. 

Carbon monoxide is absorbed by red blood cells faster than oxygen, replacing oxygen in the bloodstream when CO is inhaled. Carbon monoxide poisoning symptoms may not manifest quickly enough in people who are sleeping or have consumed alcohol, leading to death in many cases.

Certain other factors influence how someone is affected by CO exposure, including their health, physical activity level, age, and the presence of specific medical conditions like emphysema, asthma, and heart disease. If you or a loved one is at greater risk, proper education is particularly important.

How to Prevent Carbon Monoxide Poisoning

To protect your loved ones from the dangers of carbon monoxide poisoning, follow these essential safety steps.

Install Carbon Monoxide Detectors

Ensure you have UL-listed carbon monoxide detectors on every level of your home, especially near bedrooms and living areas. These alarms will alert you to dangerous CO levels, potentially saving lives.

Regular Appliance Check-ups

Have your fuel-burning appliances, such as your furnace, stove, and fireplace, inspected and serviced annually to ensure they operate safely and efficiently.

Keep Vents and Chimneys Clean

Regularly clear vents and chimneys to allow CO to escape. Wood-burning fireplaces should be serviced annually to prevent creosote buildup in your flue. Check vents and chimneys for improper connections, cracks, rust, or stains.

Avoid Idling Vehicles in Garages

Never leave your vehicle running in an enclosed space, as idling can lead to a dangerous carbon monoxide buildup. If you must start your vehicle remotely, open the garage door first.

Use Stoves and Grills Properly

Never use a gas stove or oven for home heating purposes, as this can also lead to carbon monoxide buildup. Charcoal grills emit carbon monoxide, too, so use them only in well-ventilated outdoor areas.

Snowstorm Awareness

During snowstorms, check that your vents are free of snow so carbon monoxide can flow outdoors properly.

Carbon Monoxide Detector Installation Guidelines

Follow these installation requirements for carbon monoxide detectors.

Proper Placement Matters

Install detectors on all levels of your home, including the basement and outside sleeping areas. Make sure living spaces like family rooms are also within range of an alarm. Stairways and hallways also require coverage, because CO is lighter than air and tends to settle in these spaces. 

Situate detectors at least 15 feet away from fuel-burning appliances, such as furnaces and water heaters. You’ll also need to place them at least 5 feet away from windows and doors to prevent drafts that can affect accuracy. Above all else, ensure detectors are installed according to the manufacturer's instructions.

Maintain Your CO Alarms

Test detectors monthly and replace batteries at least twice a year. Consider using long-lasting lithium batteries for extended reliability. Replace detectors every 5 to 7 years or as recommended by the manufacturer.

Hardwire or Interconnect Your Alarms

The National Fire Protection Association (NFPA) suggests using interconnected CO detectors, which will activate all detectors in your home when one is triggered, ensuring everyone is promptly alerted. A trusted electrician can help you install hard-wired, interconnected carbon monoxide detectors.

Keep Detectors Clean

Never paint your CO detectors, which can clog the vents and impair their performance. Regularly vacuum or dust your CO detectors to prevent the accumulation of dirt or dust that can interfere with their proper function.

Education is Critical

Familiarize yourself with the difference in sounds between smoke alarms and CO alarms. Treat every CO detector alarm as a real emergency. Ventilate the area by opening windows, evacuate the premises, and call for professional help. 

Familiarize yourself and your family with the symptoms of CO poisoning, which may include headache, dizziness, nausea, confusion, and fatigue.

The Physical Effects of Carbon Monoxide Poisoning

As mentioned previously, carbon monoxide binds with hemoglobin in the bloodstream, preventing the transport of oxygen to vital organs and tissues. High levels of CO inhalation can lead to loss of consciousness and even death, as the brain and other organs are deprived of oxygen.  

Even minor CO exposure can have long-term effects, impacting memory and weakening the immune system, making the body susceptible to other illnesses. A dangerous level of carbon monoxide is above 9 parts per million (ppm), with concentrations exceeding 35 ppm posing a health hazard in as little as an hour. Disorientation is common in CO poisoning, and victims often become physically and mentally incapacitated.

Symptoms of CO poisoning include:

• Headache

• Dizziness

• Nausea

• Weakness

• Vomiting

• Chest pain

• Confusion

• Loss of consciousness

Responding to a Carbon Monoxide Detector Alarm

If your carbon monoxide detector alarm sounds, follow these steps immediately.

Evacuate First

Immediately move everyone outdoors to fresh air and ensure everyone is accounted for.

Get Help

Once you’re safely out-of-doors, contact your local fire department or call 911 for assistance. Seek medical attention for anyone experiencing symptoms of carbon monoxide poisoning, such as headache, nausea, dizziness, or confusion.

Once Cleared, Ventilate

After emergency services have checked the building and verified it’s okay for you to return, open all your windows and doors to ventilate the area. You should also turn off all fuel-burning appliances. Do not restart them until a qualified technician has inspected them.

Equipment Inspection

Once the situation has been resolved, contact a professional to have your electrical system, HVAC system, and appliances inspected and serviced, including:

• Gas or oil furnaces

• HVAC systems

• Flues

• Filters and filtering systems

• Electrical systems

Note that a predominantly yellow, flat, lazy-looking flame in a natural gas furnace indicates that fuel is not burning efficiently and is releasing higher than usual levels of carbon monoxide.

General Emergency Preparedness

It's essential to know your emergency numbers, including 911, and make sure everyone in your household understands how to use them. Establish an evacuation plan and discuss it with your family to ensure everyone's safety in case of emergencies.

By following these safety measures and being prepared, you can minimize the risks of electrical accidents and create a safer living environment.
