CO school British Columbia

I like the fire departments comment on the 5ppm they measured.  "It is the same amount you would find in the hallways if someone was smoking."   This must be a pretty liberal parochial school. Of cousrse the school was aired out before they got there and I guess everyone stopped smoking.
