Carbon monoxide is a colorless, odorless gas that, if left unchecked, can cause serious health risks, and can potentially be fatal. Transient buildup of CO gas can happen very easily in small residential homes, be it from a vent pipe vibrating loose from a dryer, furnace, or water heater, or poor ventilation in your garage while the car is running. These are just a couple of harmful situations where CO gas can quickly build up and go undetected until it's too late.
