1. Information About Carbon Monoxide
(cont.)
• 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 ampli-
fy the above situations.
• Extended operation of unvented fuel-burning devices (range, oven,
fireplace, etc.).
• Temperature inversions which can trap exhaust gases near the ground.
• Vehicle 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 condi-
tion. Learn the early symptoms of exposure, and if you suspect CO poi-
soning, 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 compa-
ny for assistance.
Conditions that can Produce Low Background Carbon
Monoxide Levels
Several studies showed that background concentrations of CO in homes
located in urban areas are generally below 17ppm with peaks below
53ppm. The background levels of CO in a home can fluctuate depend-
ing on the time of the day, the location with respect to high automobile
traffic areas or CO generating factories…etc.
Prolonged exposure to low CO levels (below 30ppm) may have negative
effects on individuals with certain pre-existing medical and health condi-
tions. It is recommended that you discuss your specific health and/or
medical situation with a medical practitioner or health care provider to
determine the benefits of installing a low level CO monitor in your home.
Information About Carbon Monoxide Monitors and Alarms
– What They Can and Cannot Do:
CO alarms and monitors provide early warning of the presence of CO,
usually before a healthy adult would experience symptoms. However,
this early warning is possible only if your CO alarm and monitor is locat-
ed, installed and maintained.
