The halon will interfere with a fire anywhere within an enclosed space
that it's been injected into.  Unlike other agents, it works by 'getting
between' the oxygen molecules and the fuel molecules, and interfering with
the combustion process.  It doesn't need to be applied on top of the flames,
like a dry-chem powder does.  CO2 also works in similar way, but by actually
displacing oxygen molecules and sending them completely away from the area.
This is why CO2 isn't used in computer rooms for total flooding
applications.  Humans can exist without problems in an engineered Halon 1301
system enclosed space, but CO2 would extinquish both the flames AND the
humans in an enclosed space.   CO2 can only be used when there's a
ready-changing supply of fresh air; ie - outside.

  I stand by my original statements.
