THE FOLLOWING CONDITIONS CAN RESULT IN
TRANSIENT CO SITUATIONS
1. Excessive spillage or reverse venting of fuel
burning appliances caused by:
I) 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).
II) Negative pressure differential resulting
from the use of exhaust fans.
III) Simultaneous operation of several fuel
burning appliances competing for limited
internal air.
IV) Vent pipe connection vibrating loose from
clothes dryers, furnaces, or water heaters.
V) Obstructions in or unconventional vent pipe
designs which amplify the above situations.
2. Extended operation of unvented fuel burning
devices (range, oven, fireplace, etc.).
3. Temperature inversions which can trap
exhaust gases near the ground.
4. Car idling in an open or closed attached
garage, or near a home.
5. NEVER bring a charcoal grill inside and
ALWAYS operate a portable generator
outside, a safe distance from the house,
and well away from windows.

WHAT TO DO IN CASE OF A CARBON
MONOXIDEALARM
WARNING
Actuation of your CO alarm indicates the
presence of carbon monoxide (CO) which
can KILL YOU.
If alarm signal sounds:
1) Operate reset/silence button
(Press NEST button);
2) Call your emergency services [fire dept. or 911];
3) Immediately move to fresh air – outdoors or
by an open door/window. Do a head count to
check that all persons are accounted for. Do
not reenter the premises nor move away from
the open door/window until the emergency
services responders have arrived, the
premises have been aired out, and your alarm
remains in its normal condition.
4) After following steps 1 – 3, if your alarm
reactivates within a 24 hour period, repeat steps
1 – 3 and call a qualified appliance technician
to investigate for sources of CO from fuel
burning equipment and appliances, and
inspectfor proper operation of this equipment.
If problems are identified during this inspection
have the equipment serviced immediately. Note
any combustion equipment not inspected by
the technician and consult the manufacturers’
instructions, or contact the manufacturers
directly, for more information about CO safety
