This is a story out of Alaska, so anything is possible, but the claim here is that a bunch of junior high kids were on a trip during which they sat on a bus for several hours. After the trip, several kids complained of feeling ill and an astute person figured out that the kids had been poisoned with carbon monoxide, as their symptoms were consistent with CO exposure. A quick blood test confirmed it. The question is – how were these kids exposed? Some parents want to blame the bus they were riding on, but that is patently ridiculous. According to this article, several of the windows were frozen open! CO cannot accumulate in a moving bus when the windows are open. Simply impossible. This was reportedly an overnight trip – why has no one checked out the hotel the kids stayed in? That is a much more reasonable explanation, especially if there were no CO detectors at the hotel. Not the first time that has happened. I’m getting to the point where I’m going to start carrying my own CO detector around with me when I travel.
