• Vehicles and other combustion engines running in an open or
closed garage, attached or near a home.
• Burning charcoal or fuel in grills and hibachis in an
enclosed area.
Conditions that Can Produce Carbon Monoxide
The following conditions can result in transient CO situations:
• Excessive spillage or reverse venting of fuel-burning
appliances caused by outdoor ambient conditions, such as
wind direction and/or velocity, including high gusts of wind,
heavy air in the vent pipes (cold/humid air with extended
periods between cycles).
• Negative pressure resulting from the use of exhaust fans.
• Simultaneous operation of several fuel-burning appliances
competing for limited internal air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces or water heaters.
• Obstructions in, or unconventional, vent pipe designs which
can amplify the above situations.
• Extended operation of unvented fuel-burning devices (range,
oven, fireplace, etc.).
• Temperature inversions which can trap exhaust gases
near the ground.
• Vehicles idling in an open or closed garage, or near a home.
To be safe, know the possible sources of CO in your home.
Keep fuel-burning appliances and their chimneys and vents
in good working condition. Learn the early symptoms of
exposure, and if you suspect CO poisoning, move outside to
fresh air and get emergency help. Your first line of defense is an
annual inspection and regular maintenance of your appliances.
Contact a licensed contractor or call your local utility company
for assistance.
