What Are the Red Flags of a Carbon Monoxide Gas Leak?

Carbon monoxide (CO) is referred to as the “silent killer” for a reason. It’s clear, odorless and tough to notice without the right tools. If it collects in your home, it can rapidly turn into a serious threat for you and your family. So, how do you stay safe against something you can’t find with your senses?

The key is to use carbon monoxide detectors. These small alarm systems are the first line of defense, notifying you of the presence of CO gas before the situation gets dangerous. But aside from a detector going off, how can you know if there’s a carbon monoxide leak in your home? These are 10 signs to be aware of.

1. Condensation on Windows Near Appliances

If you see lots of condensation on your windows, particularly near a fuel-burning appliance like a gas fireplace, this could suggest that ventilation isn’t working properly. While condensation by itself may not mean CO, this clue warrants investigation.

2. Brown, Sooty Stains

Appliances that run on combusting fuel should have clear exhaust. If you notice brownish-yellow or dark stains around a furnace, fireplace or water heater, it could mean something’s wrong with the combustion process. This may point to a carbon monoxide issue.

3. Exhaust Fumes Appear Indoors

If you can smell or see exhaust fumes inside the house, you are at risk of carbon monoxide exposure. Fuel-burning appliances like cars, charcoal grills and generators should only be used safely outside the home to avoid the buildup of exhaust fumes indoors.

4. Soot in or Around the Fireplace

Your chimney should channel smoke and other gases up and out the chimney. Noticing more soot or grime is a warning sign, especially if there’s an unusual amount. A blocked chimney vent could be the culprit for why carbon monoxide is backdrafting indoors.

5. Increasingly Weak or No Draft from Your Chimney

On the topic of chimneys, a properly working one needs the strong airflow to fully ventilate smoke and other fumes. If you notice reduced ventilation or even no draft at all, your chimney might be clogged, forcing carbon monoxide back into your home.

6. Yellow or Flickering Flames

All appliances that use gas should have a clear blue flame. When the flame is weaker and yellow (and you don’t have a decorative gas fireplace), it means the gas isn’t burning properly and might be emitting carbon monoxide.

7. Solid Fuel Fires Aren’t Burning as Fast

When your wood or coal stove starts struggling to burn all the way through or has trouble staying lit, it could have a problem with airflow, heightening the possibility of CO buildup.

Signs You May Have CO Poisoning

If you don’t catch the other signs of a carbon monoxide leak in time, the next clue may soon come from your body. Symptoms of CO poisoning can be:

• Flu-like symptoms
• Headaches
• Dizziness
• Nausea or vomiting
• Shortness of breath
• Confusion
• And fatigue

If you or anyone in your family starts getting sick, especially together with any of the above signs, get fresh air immediately and call 911.

Prevent CO Poisoning and Gas Leaks with These Safety Tips

Prevention is always better than a cure, especially in the case of CO gas exposure. First, make sure you have carbon monoxide detectors in all the right places. Building codes require them outside every bedroom, on each floor of the house and in rooms with appliances like a gas stove or water heater. For an additional safety measure, it’s smart to set up interconnected detectors so that when one detects carbon monoxide, all of them will sound. Test these detectors monthly and change them when required, generally every five to seven years.

Along with installing and maintaining carbon monoxide detectors, follow these safety tips:

• Hire a professional to regularly inspect your heating system, fireplaces (both gas and wood), and any other fuel-burning appliances.
• Don’t allow anyone to use grills, portable backup generators or similar equipment inside, especially in small spaces.
• Use your stove vent if you’re cooking with a gas-powered oven, and never use these appliances to try and heat your home.
