This happens when you use way too high concentrations of HCl or both.
If the CuCl etchant is maintained at normal levels, and covered when
not in use, there is no corrosion on steel nearby.
It's well worth mentioning, so that others may avoid the tedious work
of removing rust, but i doubt it would do damage to a CO detector
which likely isn't even in the same room.

The first couple of times I etched, EVERYTHING metal in the room that I used oxidized over the next couple of days. So yes, there is a small chance that etching can damage nearby electronics. However, I would call your local FD (non-emergency #) and have them check the house for CO levels.
