Carbon monoxide is an odorless and colorless gas that can be produced by household items including burning furnaces, portable generators, and charcoal grills, according to the Centers for Disease Control and Prevention’s website.
Some common symptoms of carbon monoxide poisoning, described as “flu-like,” are headache, dizziness, weakness, upset stomach, vomiting, chest pain and confusion, the website said.
