CO is a colorless, odorless gas. Because you can't see, taste, or smell it, CO can kill you before you know it's there. In
a short period of time (as little as one to two minutes) CO can raise to dangerous levels in a home. These extremely
high levels of CO have the potential to harm occupants.
CO is a byproduct of incomplete combustion of fossil fuels such as natural gas, oil, wood or coal. Some common
causes of carbon monoxide poisoning include:
• Malfunctioning appliances
• Furnaces
• Stoves
• Ovens
• Water heaters
• Fuel burning cooking appliances
• Charcoal grills
• Motor vehicles
• Electric cars
Symptoms may include flu-like symptoms such as:
• Headaches
• Nausea
• Fatigue and tiredness
• Dizziness
• Confusion
• Breathing difficulties
The very young and old are particularly at risk, but everyone is at risk.
Summit Fire District recommends the following steps to reduce the chances of carbon monoxide poisoning:
• Purchase and install CO alarms in your home!
• Place a CO alarm on each level of your home and in areas near appliances that are potential sources of CO.
• Have a qualified professional check all fuel burning appliances, furnaces, venting and chimney systems
at least once a year or as recommended by the manufacturer.
• Never leave a motor vehicle running in an attached garage or carport where CO may enter your home
and always open the garage door when starting your vehicle.
