Carbon monoxide (CO) is often called the “silent killer” for a reason — it’s invisible, odorless, and tasteless, yet can be deadly. According to the U.S. Consumer Product Safety Commission, more than 200 people in the United States die each year from carbon monoxide poisoning, most often due to malfunctioning gas appliances. The American Medical Association reports even higher numbers and identifies CO poisoning as the leading cause of accidental poisoning deaths in the country.
Why Carbon Monoxide Is So Dangerous
Because carbon monoxide can’t be seen or smelled, it’s difficult to detect without proper equipment. However, there are early warning signs you can look for around your home. Underwriter’s Laboratories lists several potential indicators of a CO problem, including:
- Soot or dark streaks around the service door of fuel-burning appliances
- A lack of draft in your chimney
- Excessive rust on flue pipes or appliance surfaces
- Condensation on windows or walls near a furnace
- Fallen soot in a fireplace
- Water leaking at the base of a chimney or vent pipe
- Discolored or damaged bricks near the chimney top
- Rust visible on outdoor vent pipes
Recognizing Symptoms of CO Poisoning
Carbon monoxide exposure can mimic the flu. Symptoms may include:
- Headaches
- Dizziness
- Fatigue
- Tightness in the chest
- Confusion
- Shortness of breath
In some cases, a person’s skin may appear pink or red due to changes in blood pressure.
The Importance of Carbon Monoxide Alarms
If your home has gas appliances, heaters, or fireplaces, installing CO alarms is essential. Ideally, these should be interconnected with your smoke alarm system so that all alarms activate simultaneously in the event of a problem. Test each alarm regularly according to the manufacturer’s instructions, and remember that CO detectors typically last only 2–3 years before needing replacement.
If your CO detector sounds an alarm:
- Check everyone in the household for symptoms.
- If anyone shows signs of poisoning, leave the house immediately and call for medical help.
- If no one appears ill, turn off fuel-burning appliances, open windows and doors to ventilate the space, and contact a qualified technician to inspect your equipment.
Prevention Tips
The best protection against carbon monoxide poisoning is prevention. These steps can help reduce your risk:
- Never use unvented kerosene or gas space heaters indoors.
- Don’t let your car idle inside a garage, even with the door open.
- Avoid running gasoline-powered engines (such as mowers, trimmers, or generators) in enclosed areas.
- Don’t use your gas oven to heat your home.
- Never grill with charcoal indoors — even inside a fireplace.
- Have your heating system inspected at the start of each season, and have vents and chimneys cleaned at least once a year.
Protect your household by staying alert to the warning signs and keeping up with regular maintenance.
