***{The burning of combustible materials creates heated air containing
smoke and other byproducts of burning. If you were to breathe it in its
initial state before it has mixed with the surrounding air, (a) it would
burn your lungs, (b) you would be choked by the smoke, and (c) you would
die from lack of oxygen. However, because that cloud of material is
hotter and less dense than its surroundings, it rises; and as it rises,
it mixes with its surroundings and cools. That means the number of smoke
particles per cubic foot as well as the percentages of pollutant gases
such as carbon monoxide decreases, and the percentage of oxygen
increases. Result: before very long it has risen to a considerable
altitude and in the process has mixed with so much normal air that it
has become indistinguishable from normal air. This is what happens under
normal circumstances, and so it is incorrect to say, as an unqualified
generalization, that "the bad air will push the good air out of the way."

Such an outcome is normal because the atmosphere tends to be warmer near
the surface and becomes progressively cooler as the altitude increases.
The reason is that the main heating effect of the sun on the atmosphere
comes from sunlight passing through the atmosphere, being absorbed by
materials on the surface, and heating those materials. They in turn heat
the layer of atmosphere which is near the ground, which in turn heats
the air above it, and so on. Result: the temperature of the atmosphere
tends to be higher near the ground, and to decrease with altitude. Under
these conditions, a rising cloud of heated air from a fire will rise a
long way, because though its temperature is falling, the temperature of
the surrounding air is also falling. Hence it will rise further before
its temperature is equal to its surroundings, hence will mix more than
would be the case if, say, the air got hotter as altitude increased.

If the air got hotter as the altitude increased, that would be what is
called a temperature inversion. In that case, the rising cloud of
polluted air from a fire would reach temperature equilibrium with the
surrounding air at a lower altitude, hence would mix less, hence would
remain polluted longer. Result: if a coastal city were under a
temperature inversion and a VLCC caught fire in the harbor, a dangerous
situation could arise. Fortunately, stationary temperature inversions
tend to be rare, and to be shallow--which means: temperatures only rise
for the first two or three thousand meters of altitude increase, and
then begin to fall again. Thus a really big fire will probably produce a
thermal--a rising column of heated air--that is strong enough to punch
through the inversion. If it does, it will dissipate normally. It is
only if the fire is small enough so that the rising column of heated air
reaches equilibrium with its surroundings before it punches through the
inversion that it will produce a dangerous rise in airborne particulates
in a populated area. And in that case, because the fire is relatively
small, the resulting jump in particulates will in most cases be a threat
only to persons who have medical conditions such as emphysema,
pneumonia, asthma, etc. For just about everyone else, it would be
annoying, but survivable.

In summary, your premise that "the bad air will push the good air out of
the way"--meaning that it will remain near the surface and will not
dissipate--is virtually always false. That means if 500 VLCC'S were
burned in a day, the main effects would be economic: the owners of those
tankers would take a hit in the pocketbooks, and consumers would find
themselves paying higher prices for petroleum products. Otherwise, life
would go on pretty much as usual.

Bottom line: contrary to what you say, the amount of oxygen in the sky
matters.
