RE: [RC] Heaters in trailers - David LeBlanc

The molecular weight of CO is about the same as air so I don't think ?it

would sink to the bottom of the trailer.? In fact, since it is a? product of
incomplete combustion, and therefore warm, it would rise to the top of the
trailer.? Open your roof vent and you should be safe from CO poisoning.?

CO tends to sink to the bottom of the trailer (where, most likely, your

shutoff of the heater in certain situations (preferably before
asphyxiation...)? 

============================================

If there's a heater running, you're going to have enough mixing from
convection currents that I really don't think you're going to see a
measurable difference in concentration at the top or the bottom.

If you run a heater, use one that's meant for an enclosed area, and even so,
make sure you have a CO alarm installed. This stuff really can kill you, and
isn't something to mess around with.

It's also true that when you have gasses that they will evenly distribute
among a closed area, and it will do this independently of how much it
weighs. If it worked the other way, our atmosphere would have all the CO2
(48 g/mole) at the bottom, O2 (32 g/mole) next, and then N2 (28 g/mole)
would all be at the top, with a little O3 and a few other things also at the
bottom. Fortunately for us it doesn't, else this wouldn't be a very nice
place to live. Gasses move from areas of higher concentration to lower, not
by weight. It will also move around because of temperature difference, but
in a trailer, it will go up, hit the cooler roof, then come back down.
