This story has some flaws. The fire actually started during the first class of the day. Smoke was pouring into the classroom when students were in the room. They had to be evacuated to a nearby room. 2 classes had to be moved to the school's media center for the whole day. The first 2 facts in your story are inaccurate! You should probably give the school a call, and ask to speak to teachers who were outside, near the fire at the time. You could also ask one of the 20+ students who were in the room when the smoke started pouring in. The classrooms in question do not have smoke detectors installed in them. Maybe this is why it took a little while to determine ther ewas actually a fire. A number of these portable classrooms have extensive problems that have yet to be checked out.
