Carbon Monoxide: The invisible danger in your home

Carbon monoxide (CO) is often called the “silent killer.” It’s an invisible, odorless and tasteless gas that can be deadly if it builds up in your home. With colder months ahead and more reliance on natural gas appliances, it’s important to understand how to stay safe.

What Is Carbon Monoxide?

Carbon monoxide is produced when fuels like natural gas, wood, or propane burn incompletely. Common sources include gas furnaces, water heaters, fireplaces, stoves, and portable generators.

Know the Symptoms

CO poisoning can happen quickly or over time. Early symptoms often look like the flu but without a fever. Watch for these warning signs:

• Headache
• Dizziness
• Nausea
• Confusion

Severe exposure can cause fainting, chest pain, seizures, or even death. If you suspect CO poisoning, leave your home immediately and call 911.

Install Carbon Monoxide Detectors

Every home with gas appliances or a fireplace should have CO detectors. Install them on every floor, especially near sleeping areas. Test them monthly, change the batteries yearly, and replace the devices every five to seven years.

Keep Vents and Appliances Clear

Blocked vents and chimneys can cause CO to build up indoors. After heavy snow or storms, check to make sure vents are clear. Never use outdoor equipment, like grills or generators, inside your home.

Get an Annual Inspection

Have a qualified technician inspect your gas appliances, furnace, and water heater every year. Regular maintenance helps prevent leaks and ensures safe operation.

Know What to Do in an Emergency

If your CO detector goes off, leave your home immediately and call emergency services. Do not re-enter until authorities say it’s safe.

By staying informed and taking these precautions, you can keep your family safe from carbon monoxide poisoning this winter.
