dont quote me on this but i think alarms go off @ about 6-8 ppm, 10-15 you should not be exposed to and 15 on up symptoms start, as said earlier dizzy, nausea, blue lips, flu like symptoms. Never had a co problem but on warmer days (mid 40's +) I have a heat gun to get chimney warm to draft right. Was told due to lack of air inside, newer homes so tight that when some run their clothes dryer it causes problems. The theory is when dryer runs it blows air out, needs to draw air in from somewhere with todays well made doors and windows it comes from the next weekest point. A f/f friend of mine told me not long ago they ran a call to a house 3 people down, one sick, readings on thier meter was over 700ppm at the door way when they entered. Sent them all to hyperbarrick chamber. Came from backed up furnace.
