Carbon monoxide is often called a silent killer — and for good reason. The colorless, odorless gas cannot be seen or smelled, yet exposure can be deadly. The good news: carbon monoxide poisoning is preventable.
Each year in the United States, carbon monoxide poisoning sends tens of thousands of people to emergency rooms and claims hundreds of lives. Older adults, especially those age 65 and over, face the highest risk of serious illness or death from exposure.
Know the Symptoms
Carbon monoxide poisoning is frequently mistaken for the flu, especially in its early stages. Symptoms may include headache, nausea or vomiting, dizziness, drowsiness or fatigue, and confusion. Severe exposure can lead to loss of consciousness and can be fatal if not treated quickly.
Because symptoms can come on gradually, many people don’t realize they’re in danger until it’s too late.
Common Sources of Carbon Monoxide
Carbon monoxide is produced when fuels do not burn completely. Common household and everyday sources include furnaces, fireplaces and space heaters, water heaters, gas clothes dryers, and stoves. Grills, generators, power tools, and vehicles that burn fossil fuels can also produce dangerous levels of carbon monoxide, especially when used improperly or in enclosed spaces.
What to Do in an Emergency
If carbon monoxide poisoning is suspected, get to fresh air immediately. Call 911 or seek emergency medical care right away.
Poison Center healthcare professionals are available around the clock to help manage carbon monoxide exposures and determine whether emergency services are needed.
Preventing Carbon Monoxide Poisoning
Simple precautions can dramatically reduce the risk of exposure. Install carbon monoxide detectors on every level of your home and replace batteries every six months. Learn to recognize early symptoms of carbon monoxide poisoning and have all fuel-burning appliances inspected and maintained regularly.
Make sure heaters and appliances are properly vented to the outside. Never use charcoal grills, hibachis, or generators indoors. Do not use gas ovens or ranges to heat your home. Never leave a vehicle running in an attached garage — even with the garage door open — and avoid sitting in a running vehicle if snow or mud is blocking the exhaust pipe. Generators should always be run outdoors and far away from windows and doors.
