mgbinspect Posted February 11, 2010 Report Share Posted February 11, 2010 NICE! The least they could have done is increase the volume of the pipe as needed. [:-jester] (Jest kidding, of course... ) No doubt there weren't carbon monoxide detectors in the place or they'd have been reporting now and then, I guess?

Marc Posted February 11, 2010 Report Share Posted February 11, 2010 Most CO detectors do not annunciate until the concentration hits 50 ppm. 50 ppm is above the limit at which fire rescue personel in some states may enter a dwelling to rescue someone, unless they are equipped with their own breathing apparatus. The problem is the cost. The cost to manufacture a CO detector that can detect a lower ppm is too high to sell successfully on the residential market. That's what I learned several years ago from a presentation by Bacharach. Perhaps the technology has improved since. I mention this in reports on dwellings in which CO detectors are used to provide the primary defense against CO asphyxiation. Marc Link to comment Share on other sites More sharing options...
Tom Raymond Posted February 11, 2010 Report Share Posted February 11, 2010 "I mention this in reports on dwellings in which CO detectors are used to provide the primary defense against CO asphyxiation." Such as residential housing? In NY it is law that there be a CO dector on every floor. Tom Link to comment Share on other sites More sharing options...

Marc The alarms sound in response to a time/concentration function rather than at a specific level of CO. The early alarms sounded at lower time/concentration levels than the newer ones do. This resulted in lots of fire departments responding to lots of CO alarms. By the time they got to the house, the ES personnel couldn't find any CO. It was such a big problem that UL raised the threshold limit on the alarms. That's why we're at where we're at now.
