BISMARCK – November marks Carbon Monoxide Awareness Month, and the North Dakota Fire Marshal has been working to raise awareness about the dangers of carbon monoxide (CO) and the simple steps North Dakotans can take to protect their families.

Carbon monoxide, often referred to as the “silent killer,” is produced when fuels such as natural gas, propane, wood and oil burn incompletely. When CO builds up indoors, it can be lethal, especially in enclosed or poorly ventilated spaces. This risk is heightened in colder months as heating sources like furnaces, fireplaces, and space heaters work overtime to keep homes warm. In 2023, North Dakota fire departments responded to 277 CO incidents with no injuries or fatalities reported, according to a news release from the North Dakota Insurance Department.

“Carbon monoxide poisoning is a preventable tragedy that can be mitigated with proper awareness and precautions,” said State Fire Marshal Doug Nelson. “By taking simple steps to inspect and maintain heating systems, install CO detectors, and know the signs of CO poisoning, we can prevent accidents and protect our loved ones.”

CO poisoning symptoms can mimic the flu, which may delay life-saving actions. In cases of suspected CO exposure, exit the building and get fresh air immediately, then contact emergency services. Prompt medical attention is vital to prevent long-term health effects or death.

The Office of the State Fire Marshal recommends taking the following precautions:

– Place CO detectors on every floor of your home, especially near sleeping areas. Test them monthly and replace batteries twice a year.

– Have your heating system, water heater and any fuel-burning appliances checked annually by a qualified technician.

– Never run vehicles, generators or other fuel-burning engines in enclosed spaces like garages, even if the door is open.

– Early signs of carbon monoxide poisoning include headache, dizziness, nausea, confusion and chest pain. If you suspect CO poisoning, leave the area immediately and seek fresh air, then call 911.

Residents with questions about CO safety can contact their local fire department or the Office of the State Fire Marshal.
