i'm not disputing the dangers of co, nor am i trying to downplay the seriousness of it, and i am certainly not trying to make fun of, or offend anyone, but this whole thread and some of the replies have taken me by surprise to say the least. i was floored by people talking about pushing tractors in and out of garages. i'm still processing it, and i have yet to wrap my head around it. i've never heard of this until now. every commercial garage has the mechanics drive the vehicles in and out many times per day. many of these mechanics in both small and large shops have been doing it for decades. if there were more than a couple cases per million where harm came from it, you can guarantee the personal injury lawyers would be running prime time tv commercials advising of a class action lawsuit against employers who had mechanics drive customer vehicles into a building. there has got to be a pretty good dispersal rate even in most garages or you would hear about it all the time.
