Carbon Monoxide Safety Checklist During Winter Storms

Winter storms can pose significant risks, including the danger of carbon monoxide (CO) poisoning. CO is an odorless, colorless gas that can be deadly if inhaled in large amounts. During winter storms, the use of alternative heating sources increases the risk of CO buildup indoors. To protect yourself and your loved ones, follow this comprehensive CO safety checklist:

1. Install and Maintain CO Detectors

  • Placement: Install CO detectors on every level of your home, especially near sleeping areas.
  • Maintenance: Test alarms monthly and replace batteries at least once a year. Replace the entire unit every 5 to 7 years, or as recommended by the manufacturer. (epa.gov)

2. Use Generators Safely

  • Outdoor Use: Operate generators outdoors, at least 20 feet away from windows, doors, and vents. Never use them inside homes, garages, or basements. (cpsc.gov)
  • Proper Ventilation: Ensure generators are placed in well-ventilated areas to prevent CO accumulation.

3. Safely Use Alternative Heating Sources

  • Space Heaters: Keep electric space heaters at least 3 feet away from flammable materials. Never use extension cords with space heaters. (restoredcdc.org)
  • Fireplaces and Wood Stoves: Ensure proper ventilation and keep chimneys clean to prevent CO buildup.

4. Avoid Using Cooking Appliances for Heating

  • Stoves and Ovens: Do not use gas stoves, ovens, or charcoal grills to heat your home, as they can produce dangerous levels of CO. (epa.gov)

5. Clear Vents and Exhausts

  • Outdoor Vents: Remove snow and ice from furnace, stove, fireplace, and dryer vents to ensure proper airflow and prevent CO buildup. (epa.gov)

6. Recognize Symptoms of CO Poisoning

  • Symptoms: Headache, dizziness, weakness, nausea, vomiting, chest pain, and confusion. If you experience these symptoms, seek fresh air immediately and call 911. (oregon.gov)

7. Educate and Prepare Your Family

  • Awareness: Inform all household members about the dangers of CO and the importance of safety measures.
  • Emergency Plan: Develop and practice an emergency evacuation plan in case of CO exposure.

By adhering to this checklist, you can significantly reduce the risk of carbon monoxide poisoning during winter storms and ensure the safety of your household.
