Carbon Monoxide

According to the Centers for Disease Control and Prevention (CDC), more than 400 Americans die from accidental carbon monoxide (CO) poisoning every year. CO is a gas that is odorless and colorless, and it can be fatal if too much is inhaled. CO poisoning can be prevented by watching for symptoms, testing CO alarms in your home and regularly checking common CO producers for leaks, blockages or faults.
