why not inert those areas as well?


The problem would be to effeciently purge and then keep the inert gas in the
area. Most all effective inert gases are lighter than air and would be lost
as fast as you could pump it in.

co2 is heavier than air, Argon or nitrogen are cheap. Just let it flood
the area while you are working....For the time needed to do the cutting
or welding, the losses are negligible.

I'm sure this doesn't really need to be told to careful, experienced
people, but be real careful if you are flooding bilges with something
like nitrogen. Industrial workers have died of lack of oxygen by
entering a tank that contained nitrogen from a purging operation
rather than air.
