Remember as a kid the old Pyrene fire extinguishers in vehicles and various other places. You occasionally see the hand pump one (less contents) in antique shops. Nice polished brass cylinders.
Carbon tetrachloride (CTC) was greatly used in the dry cleaning industry. Gave off the most evil toxins when used on fires.

Big issue with BCF (Halon etc) was/is it's effect on the ozone layer. Still one of the most effective extinguisher compounds around.
The company I worked for and Air NZ had dispensation to continue using Halon after it was banned in NZ although that I imagine has long since lapsed now.
