Very sad news. That unfortunate accident could have happened to anyone, any city, USA.
Sad story... I never would have thought that a charcoal grill put out carbon monoxide fumes...
This is sad but not an unfortunate accident. It was completely preventable. Proper use of a genny and an operating CO detector.
If you don't have a CO detector in whatever quarters you are living in, and use fuel for heat or use a generator, you put yourself in danger.
Charcoal grills, especially when the coals are "smoldering" along put out tremendous amounts of CO.
We once had a 9-11 call for a CO detector going off at a 1 family home. We had readings high enough to cause concern, but not life threatening.
It was probably close to an hour before we found the source - a charcoal grill in the garage of the house next door! Fortunately for those people who did not have a CO detector, they were at work.
With the economy now, public safety workers are the bane of society, and our work load has really changed over the years - thanks to mandatory smoke and CO detectors.
Check your batteries at least once a year and 6 months later change them (every 6 months you are either changing or checking). And if you don't have smoke and CO detectors - shame on you.
