Super interesting. I just outfitted my bedroom workshop with minimal first aid stuff (a wall mounted box with bandages and stuff as well as wall mounted eyewash bottles and a fire extinguisher)

I have been looking at respirators; I didn't get one 'cause my workshop isn't a chemistry lab, but I did look at them, and apparently one option is a bottle of compressed air with a valve so you can breath the compressed air.

The idea, of course, is that no matter how toxic whatever you released into the air was, if you were breathing this compressed air thing it wouldn't get into your lungs.

But... aside from avoiding the halon, I hadn't thought of it as something you would want in a fire and not just in a toxic gas situation, but from your description, it sounds like it'd really help you get out of the building.
