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.
