Thank you , SugarMagnolia, for the answer. That makes sense that the rescuers had monitors. Thank God the family is ok.

In the interest of accuracy and consistency, the Advocate might want to change the graphic. CO2 is carbon dioxide, and the article is about carbon monoxide. They are not interchangeable.

momof2 - from reading the text, if I am reading it right, the only detectors mentioned were those used by the rescuers. Canales was not referring to HER detectors, so I gather the house had no CO detectors in place? Thank goodness the family is alright.

Good going VicAd, and yes, it is once again open season on calling SugarMagnolia a nitpicker, so....pick away.

One little thing: your graphic at the top has a skull and crossbones by CO2, or carbon DIOXIDE. Carbon monoxide is CO. Could you please correct this? Just don't want others to be misled. Anyone who took high school chemistry, though, should know the difference.

However, in your text you have gotten it completely right, a very informative article that vividly illustrates a textbook case of CO poisoning. Once again, an informative and well-written article by Sonny Long. Thank you for informing the public about this killer, and please people: BUY those CO monitors and REPLACE the batteries when you replace your smoke detector batteries. They could save your life.

I am just curious as to why if the detectors were going off they did not hear them, or do the detectors go off only when it is already at a high level. Serious question because I have the detectors and thought they would wake me up if sleeping, but maybe not until it may be too late???

Thank god the family is ok!!!! :0)
