Carbon Monoxide: Symptoms of Poisoning

Due to the gas's odorless and colorless properties, carbon monoxide symptoms are often the first clue that you have a problem. These symptoms may improve once you leave the home, but will quickly reoccur upon return. Carbon monoxide is a quick acting and deadly gas, so it's important to be aware of common carbon monoxide symptoms.

Symptoms of Carbon Monoxide Poisoning

Low and moderate levels of carbon monoxide poisoning are often confused with the flu symptoms, such as:

• Shortness of breath


• Nausea and headache


• Dizziness and light-headedness

High levels of carbon monoxide can cause chest pain, confusion, impaired vision and coordination, and can be fatal within minutes. Therefore, installing carbon monoxide detectors is a smart step for every home.

If you find evidence of carbon monoxide in your home and have had carbon monoxide symptoms get fresh air immediately. Then open the windows and doors to your home and turn off any combustion appliances. If you suspect carbon monoxide poisoning, go to the emergency room.
