Symptoms of carbon monoxide poisoning include headaches, dizziness, nausea, fatigue, shortness of breath, confusion, blurred vision, chest pain, and loss of consciousness. CO is colorless, odorless, and tasteless — symptoms can develop over hours or appear suddenly with high exposure. If anyone feels these symptoms and a CO alarm sounds, leave the home immediately and call 911.
