CARBON MONOXIDE DANGERS RISE AS HEATING SEASON BEGINS

By Scanner Alerts Media Group – October 12, 2025

As temperatures drop and heating systems start running, safety officials are reminding residents to take precautions against carbon monoxide (CO) poisoning. Carbon monoxide is an invisible, odorless gas that can quickly become deadly if inhaled in enclosed spaces.

Understanding the Risk

Carbon monoxide is produced when fuels such as gas, oil, wood, or propane do not burn completely. Faulty furnaces, clogged chimneys, and indoor use of generators are common causes of elevated CO levels during the winter months. Because CO cannot be seen or smelled, it is often called the “silent killer.”

Tips to Prevent Carbon Monoxide Poisoning

• Install working carbon monoxide detectors on every level of your home and outside sleeping areas.

• Test detectors monthly and replace batteries twice a year.

• Have heating systems, chimneys, and fuel-burning appliances inspected and serviced annually by qualified technicians.

• Never run vehicles, generators, or grills inside garages or enclosed spaces—even with doors open.

• Make sure vents for dryers, furnaces, and stoves are clear of snow and debris.

• If a CO alarm sounds, leave the home immediately and call 911.

Common Symptoms of CO Exposure

Early symptoms can resemble the flu, including headache, dizziness, nausea, and confusion. Prolonged exposure can cause unconsciousness or death. If multiple people in a home experience these symptoms at the same time, it may indicate CO buildup.
