vent pipes (cold/humid air with extended periods between
cycles), negative pressure differential resulting from the use of
exhaust fans, simultaneous operation of several fuel-burning
appliances competing for limited internal air, vent pipe connec-
tions 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 gasses near the
ground, car idling in an open or closed attached garage, or
near a home.
CO Safety Tips
Every year have the heating system, vents, chimney and flue
inspected and cleaned by a qualified technician. Always install
appliances according to manufacturer’s instructions and adhere
to local building codes. Most appliances should be installed by
professionals and inspected after installation. Regularly exam-
ine vents and chimneys for improper connections, visible rust,
or stains, and check for cracks in furnace heat exchangers.
Verify the color of flame on pilot lights and burners is blue. A
yellow or orange flame is a sign that the fuel is not burning
completely. Teach all household members what the alarm
sounds like and how to respond.
Symptoms of CO Poisoning
Initial carbon monoxide poisoning symptoms are similar to the
flu with no fever and can include dizziness, severe headaches,
nausea, vomiting and disorientation. Everyone is susceptible but
experts agree that unborn babies, pregnant women, senior citi-
zens and people with heart or respiratory problems are especial-
ly vulnerable. If symptoms of carbon monoxide poisoning are
experienced seek medical attention immediately. CO poisoning
can be determined by a carboxyhemoglobin test.
