Understanding Carbon Monoxide Risks During Winter Storms

Winter storms bring not only cold temperatures and heavy snowfall but also hidden dangers like carbon monoxide (CO) poisoning. Understanding the risks and taking preventive measures can safeguard your health and well-being.

What Is Carbon Monoxide and Why Is It Dangerous?

Carbon monoxide is a colorless, odorless, and tasteless gas produced by the incomplete combustion of fuels such as gas, oil, kerosene, wood, or charcoal. When inhaled, it can interfere with the body's ability to transport oxygen, leading to symptoms like headaches, dizziness, weakness, nausea, and, in severe cases, death. (epa.gov)

How Do Winter Storms Increase CO Risks?

During winter storms, power outages are common, prompting many to use alternative heating sources. This includes portable generators, gas-powered heaters, and even car engines running in garages. These practices can introduce dangerous levels of CO into indoor environments. (uvahealth.com)

Common Sources of CO During Winter Storms

  • Portable Generators: Often used during power outages, they emit CO and should never be used indoors or near windows and vents. (cpsc.gov)

  • Gas-Powered Heaters: Devices like kerosene heaters can produce CO if not used properly. (epa.gov)

  • Vehicle Exhaust: Running a car in an attached garage, even with the door open, can lead to CO buildup inside the home. (mass.gov)

How to Protect Yourself and Your Family

  • Install CO Detectors: Place detectors near sleeping areas and on every level of your home. Test them monthly and replace batteries annually. (epa.gov)

  • Maintain Heating Systems: Ensure that furnaces, chimneys, and vents are clean and free from blockages. Have them inspected annually by a qualified technician. (nyc.gov)

  • Use Appliances Safely: Never use gas ovens or stoves to heat your home. Avoid using charcoal grills or hibachis indoors. (nyc.gov)

  • Clear Snow and Ice: Remove snow and ice from outdoor vents to prevent CO from entering your home. (epa.gov)

  • Properly Use Generators: Operate generators outdoors, away from windows and vents, and at least 20 feet from your home. (cpsc.gov)

What Are the Symptoms of CO Poisoning?

Early signs include headaches, dizziness, weakness, nausea, and confusion. If you experience these symptoms, move to fresh air immediately and seek medical attention. (epa.gov)
