Carbon monoxide is a colorless, odorless gas that can be very dangerous. It is produced when fuels like gasoline, wood, or natural gas do not burn completely. Because it is hard to detect, carbon monoxide can build up in enclosed spaces, leading to poisoning. Symptoms of exposure include headaches, dizziness, and confusion, which can be life-threatening if not addressed quickly. To stay safe, it's important to have carbon monoxide detectors in your home. These devices can alert you to dangerous levels of the gas, allowing you to take action. Regular maintenance of appliances like heaters and stoves can also help prevent carbon monoxide buildup.
