Texas Ice Storm 2026: How Do I Prevent Carbon Monoxide Poisoning? What Are the Signs Of It In My Home?

With winter weather headed for Central Texas, it’s important to note that carbon monoxide poisoning is a serious risk and take precautions to make sure your home is safe. The odorless gas can accumulate in homes when a heater or generator isn’t properly ventilated and can prove fatal for whoever is inside.

Every year, more than 150 Americans die from carbon monoxide poisoning and thousands visit the emergency room with symptoms.

The first thing you can do, according to the United States Fire Administration, is install CO alarms inside your home, especially in locations where you’ll hear it if it happens to go off. Make sure all the vents in your home are free of dirt and debris.

If you’re using a portable generator, make sure that it stays outdoors in a well-ventilated area away from any door, window, or vent. Don’t let your generator get wet, because that is an electrocution risk, connect appliances using industrial extension cords, and turn it off before refueling.

How big a factor was carbon monoxide poisoning during the 2021 Texas Winter storm?

The storm claimed the lives of 246 Texans. About 20 of these deaths were attributed to carbon monoxide poisoning. As many Texans went powerless for days in the cold, many turned to generators or using the fireplace without realizing the harm that was building up indoors.

What causes carbon monoxide in homes?

According to Carrier:

• Cigarette smoke
• Gas appliances like stoves
• Fuel-burning heaters
• Car exhaust
• Blocked chimneys/flues

How can I tell if there's carbon monoxide in my home?

Symptoms of carbon monoxide poisoning include headache, dizziness, fatigue, nausea, confusion, irritability, and impaired memory and coordination. If anyone in your home is displaying these symptoms, take immediate action to call emergency services personnel.

The U.S. Environmental Protection Agency reminds people to check and open fireplace flues, regularly inspect heating systems and chimneys, and select wood stoves in compliance with EPA emission standards.

Additionally, the EPA advises against using a charcoal grill indoors, heating homes with gas ovens, and idling cars in the garage—even if the door is open.
