There seems to be differences of opinions on the properties of carbon
monoxide gas. One source says its heavier than air another says its
lighter, so.......is it heavier or lighter than air?

To be honest I rather trust the info from this forum than various
websites and media types.




this is something i don't understand and have been wanting to ask here.
there have been posts about filling vessels with internal combustion engine
exhaust fumes as a in-a-pinch back purge. thing i was wondering was, isn't
carbon monoxide (as a component of exhaust gases) flammable/explosive?
isn't carbon monoxide what is produced as "fuel" in a wood gassification
generator?


b.w.
