12 Carbon Monoxide Dangers to Watch This Holiday Season – Rutgers University Camden

Why Carbon Monoxide Is a Silent Threat

Carbon monoxide (CO) is colorless, odorless, and can accumulate quickly in homes during the winter months. The New Jersey Poison Control Center reports that 58 people, including children, were treated for CO exposure this holiday season alone. The risk is real and present in every household, especially when portable generators, space heaters, and other fuel‑burning devices are used indoors.

Recognizing the Symptoms

Early signs of CO poisoning often mimic flu‑like illnesses—headache, dizziness, nausea, and confusion. Because these symptoms are common, many people dismiss them until the situation worsens. If you notice a sudden improvement when you step outside, CO may be lurking inside.

12 Carbon Monoxide Dangers to Avoid This Holiday Season

1. Everyone is at risk: From infants to seniors, no one is immune.
2. Symptoms can be hard to recognize: They resemble the flu or COVID‑19.
3. It is invisible: CO has no color.
4. It is odorless: You cannot smell it.
5. It gives no warning: It is truly a silent killer.
6. Vacation rentals may lack detectors: Bring a portable CO detector.
7. Install detectors on every level: Place one outside each sleeping area.
8. Dead batteries don’t save lives: Test and replace batteries twice a year.
9. Keep vent pipes clear: Snow can block airflow.
10. Check for clogged chimneys: Inspect and clean before winter use.
11. Use heaters properly: Follow instructions and use indoor‑rated models.
12. Generators must stay outdoors: Keep them at least 20 feet away and face exhausts away from the house.

Preventive Measures for the Holiday Season

Installing a carbon monoxide alarm is the most effective way to protect your family. Place one on every floor and test it regularly. If you live in a vacation rental, ask the host about working detectors before you arrive.

For those using portable generators or space heaters, keep them outdoors and follow manufacturer guidelines. Never run a generator inside a garage or near an open window.

What to Do If a Carbon Monoxide Alarm Sounds

1. Get everyone, including pets, outside immediately.
2. If someone is unconscious or hard to wake, call 911.
3. Contact the New Jersey Poison Control Center at 1-800-222-1222 for guidance.

Ignoring an alarm can be fatal. The sound of the alarm is your first line of defense.
