Part Four – What to do When the
Alarm Sounds
Sometimes it’s Difficult to Find the Source of
CO in a Home
It can be difficult for responders to locate the source(s) of CO if:
•The house was ventilated before they arrived and the fresh air
caused the CO to dissipate.
•The CO problem was caused by a source that fluctuates on
and off, sometimes creating CO and sometimes not. Such a
situation makes it nearly impossible to pinpoint the source of
CO in a short period of time.
•The cause of CO problem was backdrafting – when air in
a chimney or flue is sucked into the home instead of venting
outside. The exact situation that created a negative air pressure
inside the home (the cause of backdrafting) is difficult to recreate
during an investigation for CO. Sometimes the CO problem
disappears when a door or window is opened. Backdrafting may
or may not happen again.
