Second, small amounts of CO will NOT do any permanent damage to the human body.

What I said too, but don't expect anyone on this forum to ever admit they're wrong.

Since the topic being dealt with here is a life or death one, you might want to be absolutely sure of yourself before being to glib about it. If a person has CO poisoning at lower levels, they may very well recover…. but that doesn’t mean that the recovery is so perfect that it’s as if it never happened. You might want to read this OSHA fact sheet…. See the last paragraph under ‘How Does CO harm you?’ https://www.osha.gov/OshDoc/data_General_Facts/carbonmonoxide-factsheet.pdf Obviously, all of this depends on the factors that are unique to a particular situation i.e. what concentration, for how long and the particulars of the person who was exposed.
