According to a U.S. Consumer Product Safety Commission (CPSC) report, engine driven tools (including electric generators) cause more non-fire CO deaths annually than gas furnaces, water heaters, and ovens combined. In fact, since 2005, there have been over 72% more CO deaths from engine driven tools than from heating systems.
I posted about the danger of low levels of CO which UL listed CO detectors will not detect. This is making some people very sick.
Checking the peak CO levels after driving to inspections was certainly an eye-opener. Put it this way: now I know why people tend to get drowsy at the wheel.
I don’t think I’ve ever seen a documented case of a fatality due to a cracked heat exchanger.
This one was due to faulty (i.e. blocked) venting…no mention of a cracked heat exchanger.
But it is the death knell of the furnace.
And excessive CO in the home is certainly a health hazard. Period.
Can’t argue with that.
