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.
