We’ll cover the risks related and provide advice on steps you can take to protect your home. Knowledge is the first step to keeping your loved ones safe, and finding yourself free from worry.
What is Carbon Monoxide Poisoning?
Carbon monoxide poisoning is low risk but dangerous when it occurs. It occurs when dangerous amounts of carbon monoxide (CO) fill your blood. This thread-like gas binds to hemoglobin and prevents the body from being able to carry oxygen efficiently. Consequently, it can lead to serious or even deadly effects.
CO is deadly in a way that is especially deceptive. It is odorless, tasteless, and invisible, meaning that without the right detection equipment, it cannot be sensed. Yet every year more than 400 Americans die from non-fire related carbon monoxide poisoning. On top of that, more than 100,000 people flood emergency rooms, and more than 14,000 are hospitalized.
Understand Carbon Monoxide
Carbon monoxide is an odorless, colorless, toxic gas byproduct of combustion that is produced when any fuel—such as natural gas, oil, wood, or coal—burns, including in our homes. Common household appliances such as furnaces, stoves, and water heaters can release CO if they malfunction or are improperly ventilated.
This is why it’s known as the “silent killer.” A potential source could be a gas-powered or oil-fueled appliance’s burner, which makes annual service and maintenance extremely important.
How CO Affects Your Body
Once it enters the body, CO binds with hemoglobin in blood, displacing oxygen. This prevents oxygen from being delivered to all the body’s vital organs leading to acute symptoms including dizziness, headache and confusion.
Long-term exposure may result in permanent brain damage, organ failure, or death. Because high levels of CO can incapacitate the body within minutes, it is critical to act quickly.
Differentiate Acute vs. Chronic Exposure
Acute exposure occurs in a short period, minutes to hours, and can lead to sudden onset symptoms like nausea or fainting. Chronic exposure, over weeks or months, can cause symptoms like persistent fatigue or memory issues.
Both types are equally insidious and deadly, but they can be avoided with proper safety precautions.
How Does CO Enter Your Home?
Carbon monoxide (CO) is a deadly, colorless, odorless gas that can invade your home, sometimes without you even knowing it. Understanding the potential carbon monoxide leak routes is essential to protecting your family. CO usually enters your home through appliances and systems, including a defective furnace and clogged filters you use every day.
Common Sources of CO Production
In reality, there are many common household devices and systems that can create carbon monoxide while in use. Gas stoves, furnaces, water heaters, and fireplaces are common offenders. For example, a malfunctioning gas stove can release CO into your kitchen, while a clogged chimney can back up fumes from your fireplace.
Vehicles operating in attached garages are a deadly danger. Even with the garage door open, exhaust can seep into your home. These are particularly dangerous because portable generators are commonly used during power outages. When located too near a home, these can release CO concentrations powerful enough to be deadly in just minutes. To reduce your risk, always use them at least 25 feet away from and downwind of your home.
HVAC Systems and CO Leaks
Poorly operating heating systems, such as bad furnace ducting or broken blower motors can be major contributors to CO migration and releases. Units that are poorly vented can trap CO inside, so having these units regularly checked is critical. Proper venting is key, since clogged or broken ventilators can lead to fatal accumulations.
With a quick annual inspection you can rest assured that your system is both safe and operating efficiently.
Impact of Improper Ventilation
Retrofits like blocked vents or flues can lead to a carbon monoxide leak, preventing CO from being safely exhausted and allowing it to build up. Poor airflow exacerbates the issue, making it essential to keep ventilation systems clear for furnace safety.
What Are the Dangers of Carbon Monoxide?
Carbon monoxide (CO) poisoning is a deadly, largely preventable health threat that we all need to take seriously. This invisible tower of terror is commonly known as the silent killer, the insidious gas that you can’t detect without a specialized device. Each year, more than 400 Americans lose their lives to unintentional CO poisoning, while tens of thousands require medical care.
Heating system malfunctions, obstructed ventilation, or lack of proper fuel combustion are common culprits. This is particularly dangerous during winter months, when over half of CO-related fatalities happen. Even low-level exposure can cause long term health effects, which makes early detection and prevention absolutely crucial.
