He's half right. A CO detector in the garage can go off when
you start the car or pull it in and trap some before you turn
it off. As for smoke detectors, there are types that work just
fine.

Thanks, Ed.

In a garage a CO detector might be subject to "false positives",
got it.

Again, why would you put a CO detector in the garage?

That is why you don't.



That really poses a problem for the many homes in AZ that have gas
water heaters in the garage.


The CO detector in the house is the one that is important. In a garage, you
can open the big door and vent too. In the garage, every time you move the
car in or out you have the potential to set it off.
