The Pennsylvania Rail Road apparently was having issues with locomotive fires inn the mid 1950s, and so they produced a training film addressing firefighting.

For instance, the ex-US Army T-Boat my Sea Scouts ship used had a fixed CO2 installation. It was, I believe, later replaced with a Halon installation. But we also had a liberal supply of hand held CO2 extinguishers.

New halon is not available but recovered/recycled halon continuities to be available with pricing based on supply. The last 2.5lb halon extinguisher I discharged several years ago cost like $150 to refill but powder would have made a much more expensive mess. There are also halon substitutes that are better than CO2 but not quite as effective that are likely used when large systems are discharged.

HI-FOG systems work pretty well.
If you are in the space when the HI-FOG goes off, you can still breathe.
Not so much when a Halon or CO-2 system discharges.
Here is a older youtube of a HI-FOG system and a actual shipboard fire.
It is a little long, but worth watching (at least the putting out the fire part).
