What to Know About Carbon Monoxide Leaks and Detectors

carbon monoxide leaks and detectors

Carbon monoxide (CO) is invisible and gives off no odor. The gas is a byproduct of combustion when carbon molecules don’t completely burn. Coal, propane, fossil fuels, wood, and other flammables can all create CO. 

Not only is it hard to detect—it can be deadly. CO poisoning sends 20,000 Americans to the emergency room every year. Around 4,000 people need further hospitalization, and 400 will die. 

Resicon LLC wants our neighbors in Washington to stay safe and healthy, with excellent indoor air quality. From our desk, here are the facts on CO: 

Understanding the Risks

Carbon monoxide is a toxic gas. It may be the number one lethal poison in industrialized countries, contributing to half of all poisoning deaths. When inhaled, it quickly displaces oxygen from the bloodstream. This prevents the brain, heart, and other vital organs from functioning. 

However, its lethality depends on two factors: concentration and duration. Smaller amounts are less risky than large amounts. The length of exposure also plays a role. Small leaks are more common in home settings. Residents may notice more gradual symptoms that can be mistaken for illness. If a leak happens in a factory, it’s often larger and deadlier. 

Know The Symptoms

The severity of symptoms usually depends on the amount of exposure. People often mistake moderate symptoms for an illness, such as the flu. Severe symptoms are much more pronounced and fast-acting. 

Children, the elderly, and those with medical conditions are more at risk for fatal poisoning. People who are asleep or intoxicated are also vulnerable since they may not notice symptoms. 

People suffering from CO poisoning may experience moderate symptoms like: 



-chest pains



More severe symptoms include:


-respiratory problems


-blurred vision

-passing out

Unsafe Levels

Any level of airborne CO is unhealthy. Most healthy people won’t notice any symptoms if exposed to 1-70 ppm (parts per million) of CO, according to the US Consumer Product Safety Commission. However, a person with a heart condition may notice chest pains. Levels above 70 ppm give rise to headaches, stomach pains, and fatigue.

After 150 ppm,  anyone exposed for too long is at risk of fainting, hallucinations, or death. 

Protecting Your Home

While the risks are scary, there is plenty you can do to keep your Tacoma household safe from CO poisoning. 

CO Detectors

Make sure you correctly place and maintain your carbon monoxide detectors. Install one per floor in your home. The US Environmental Protection Agency (EPA) recommends placing the alarms at least five feet off the floor, not too close to your fireplace or stove. Follow your instruction manual for cleaning procedures, replacing batteries, and testing the alarm.

Home Appliances

Be sure you read the instruction manuals on all of your home appliances that use combustion (stoves, furnaces, water heaters). Schedule annual maintenance inspections. You should also be sure to follow proper ventilation practices when using your fireplace and have your chimney cleaned. 

Safety Practices

Never leave your gas stove running when you’re not using it. Additionally, don’t leave your car running in the garage, even when the door is open.
