Carbon monoxide (CO) is often called the silent killer—a colorless, odorless gas that can quickly become dangerous when it builds up indoors. Every year, hundreds of families across Chicago and the U.S. experience carbon monoxide poisoning due to faulty appliances, poor ventilation, or lack of early detection.
Knowing how to prevent exposure and respond to potential danger can save lives. At Heatmasters, your safety is our top priority. Let’s go over the key dos and don’ts of carbon monoxide safety and how you can keep your home safe with the right tools and knowledge.
Recognizing Carbon Monoxide Poisoning Symptoms
Because carbon monoxide can’t be seen or smelled, understanding the warning signs of exposure is critical. Common carbon monoxide poisoning symptoms include:
- Headache, dizziness, or lightheadedness
- Nausea or vomiting
- Shortness of breath or chest pain
- Confusion or blurred vision
- Fatigue and weakness
If these symptoms come on suddenly—especially if more than one person feels them—go outside for fresh air right away and call 911. Once outside, contact a medical professional or go directly to the emergency room. Tell the doctor you suspect carbon monoxide poisoning so they can perform a blood test right away.
The DOs: How to Stay Safe from Carbon Monoxide
A few proactive steps can help you drastically reduce the risk of CO exposure:
1. Install and Maintain a Carbon Monoxide Detector
Every home should have a carbon monoxide detector or carbon monoxide alarm on each level—especially near bedrooms. These devices can alert you early to the presence of CO, giving you critical time to evacuate and call for help. Test alarms monthly and replace batteries twice a year.
2. Schedule Regular HVAC and Appliance Inspections
Have all fuel-burning appliances—like furnaces, water heaters, and stoves—checked by a licensed HVAC technician at the start of each heating season. Professionals can detect leaks, ventilation issues, or combustion problems before they become hazardous.
3. Ensure Proper Ventilation
Always use appliances that vent outdoors when possible. Keep vents and chimneys clear of debris, snow, or bird nests, and crack a window slightly when using gas appliances to improve airflow.
4. Follow Manufacturer Guidelines
Always read and follow the instructions that come with any fuel-burning appliance. Use only the proper type of fuel, and ensure the area around the unit is well-ventilated.
5. Take Action if You Suspect a Leak
If you think there’s a CO leak:
- Turn off all combustion appliances immediately.
- Open doors and windows to let in fresh air.
- Leave the building and call for emergency assistance.
The DON’Ts: Avoid These Dangerous Habits
Even a small mistake with a fuel-burning device can have serious consequences. Always remember:
- DON’T run your car inside a garage, even with the door open.
- DON’T use a gas oven to heat your home.
- DON’T use charcoal grills or camp stoves indoors—not even in a fireplace.
- DON’T sleep in a room with an unvented gas or kerosene heater.
- DON’T use gasoline-powered tools (like lawn mowers or snow blowers) in enclosed areas.
- DON’T ignore symptoms—especially if several people in your home feel ill at the same time.
