Carbon monoxide (CO) is an odorless, colorless gas. It’s formed during incomplete burning of fuels, such as gasoline, kerosene, natural gas, oil, coal, or wood.
Carbon monoxide is also found in cigarette smoke and vehicle exhaust. In homes, carbon monoxide can quickly build up from a poorly vented or malfunctioning heater, furnace, range or any fuel-powered appliance, or even from a car left idling in a garage.
Carbon monoxide is the most common cause of fatal poisonings. Wisconsin State Law now requires carbon monoxide (CO) detectors in all residences in Wisconsin.
If your CO detector sounds, or if you experience any of the symptoms below and suspect carbon monoxide exposure, take immediate action. Get fresh air immediately. Call your local fire department and move everyone outdoors into fresh air.
Do not re-enter the building until it has been inspected and declared safe.
