Because you’ve provided ventilation by leaving your windows
and doors open, the CO may have dissipated by the time help
responds. Although your problem may appear to be temporarily
solved, it’s crucial that the source of the problem is determined
and appropriate repairs are made.
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 peak level function on
your Kidde CO Alarm helps the responders know how
severe the problem was before they arrived.
–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 back drafting – when air in a
chimney or flue is sucked into the home instead of venting
outside. The exact situation that created a negative air pres-
sure inside the home (the cause of back drafting) is difficult
to recreate during an investigation for CO. Sometimes the
CO problem disappears when a door or window is opened.
Back drafting may or may not happen again.
