Halon (was A6 dash fires)

[William Magliocco]

I beg to differ.  It is no longer installed in new
fire suppresion systems due to the same types of
problems that put R-12 and is putting R-22 out to
pasture.

Old systems can stay in place, just like in cars.  

Simply read the following:

As you can see, our euro friends are a bit more
aggressive about getting rid of the stuff.

To me, "obsolete" refers to something that is no
longer made or is no longer supportable/soon to be
unsupportable...it does NOT mean that the item no
longer works.

Using the HVAC world as an example, I am no expert but
I do hold a EPA section 609 permit.  From that limited
perspective, I will state that R-12 is a far better
refrigerant than R-134a.  However, R-12 is no longer
made or able to be legally imported into the US.  The
feds have taxed r-12 into the stratosphere to force
you to upgrade your car's A/C system or to simply junk
the car.  The auto industry quit using R-12 in new
cars about a decade ago.

However, if you have a r-12 system in good shape you
can spend the $50+ per pound for a recharge...

If you're library has a good Halon system, great. 
Let's hope it stays that way.

OAC-Audis use R-12 or R-134.  Some owners have fire
suppresion systems in their cars.
