Halon isn’t used any more, FM-200 is the modern gas.

Halon was banned under the Montreal Accords as an ozone depleting material, just like some of the better (thermodynamically) Freons.

Haa, haa, haven’t heard about the ozone layer in a while, not since they proved there was no depletion (I know some idiots still hang on to the belief).

Thanks for the update. I learned about Halon while serving in the Navy, 20 years ago.
