Subject: Re: [Homebrew_PCBs] Safety Question – Carbon Monoxid e & Homebrew PCB

No part of a PCB manufacturing contains carbon, so it's
unlikely that CO can be produced other than by burning
something.
The only burning you mention are the furnace and the car.
Check them. A remote chance is that some hidden electrical
conductor might be 'almost' burning it's duct... fire
hazard! although I believe it would produce more Cl than
CO.
