Those powder fire extinguishers sure do make a horrible mess !

I had the opportunity recently to try out a small halon fire extinagisher I've been keeping around, like in cars, or even take one on test drives..
I had a collum of gasoine flame two feet tall and a foot wide.
I held this small ( about 2.5 inches in diameter, 10.5 inches tall ) Halon extingisher at the top of the flames pointed down,
and give it one short burst. Like not even a whole second of a shot. Just one quick burst. 

 the flames were instantly out. Nothing was burnt.  Nothing was even hot. I happened to have a qt yogurt container with 1 and 1/2 inches of gasoline in it, that burst into flames. 
The liquid gas that hadn't ignited was still an inch deep in the yogurt container !  Amazing.
Halon production was stopped or cut back due to ozone depletion reasons ( google or wiki it ) ...
but man does that stuff work !!! 

it doesn't just displace the oxygen I don't think...it 'neutralizes' flame of something.
there are modern replacements for Halon and I don't claim to know much about Halon for extinquishing fires, other than it works fantastically on gasoline.
About 18 years ago a parts store was selling these little extinaqiahers for about $ 22 I think. I bought 4.
This is the first time I've used one. 

and 'the trick' always, in gasoline fires is catch them immediately.  Once they get going you're in big trouble, but caught in the first 30 seconds or so, I've put out several, on cars...just got get 'em immediately. 

When a fire starts like that ...it puts you very, very much 'in the moment' ....I had two extinquishers within 6 feet of me, and another about 20 feet away. I just thought at the time........I think I'll try this little halon ....man did it work.

  Last Monday I pulled into a gas station in Corvalis and there parked next to
  the convenience store at the gas station was a new hybrid (not a Prius but
  didn't get the make) with hood up and a guy standing there squirting into
  the engine compartment with a big powder fire extinguisher. Not a total
  conflagration and they got it out but what a mess under the hood from the
  extinguisher. Don't know if electrical or fuel. Guess he needed to
  reminded to change fuel lines and electric cables?
