I've kept a fire extinguisher in My S pretty much since owning one (it may need replacing now). I understood that you only get one go at putting it out. Always makes me chuckle when people ask what the purpose of the fire extinguisher is for when they get in for the first time.
I will change it over for a powder one now.

Will probably not work as it's well past its sell-by date.

I've done the same firefighting training that Loftust has, plus the aircraft firefighting one, and have been a race marshall and attended at a number of crashes.
An in-car extinguisher is designed to prolongue the time available to the driver / marshalls to get the driver out of the car. Approved types for motorsport are AFFF or Halon only.
As a track marshall, I've seen a car burst into flames on a few occasions. This is normally due to oil or fuel coming into contact with hot exhausts. The onboard extinguisher will keep the driver from burning, but in most cases, particularly if the fire is already established, it won't put the fire out completely. Marshalls usually carry 9l AFFF and Powder and will then put out the fire. Normally, one extinguisher is enough, but if it isn't, the guys from the next post along will bring reinforcements and ultimately, the circuit fire tender has a huge AFFF tank onboard.
Dry powder is the best thing for a fuel fire, but arse at anything else. AFFF is the best all rounder by far. And bigger is better...

Most vintage racers prefer halon because it is incredibly effective. Powder is next most effective and recommended but totally fubars your car.
I will happily admit my knowledge is about 15 years old on this

Fluffyninja say:

Which rather begs the question; once everyone's out, WTF is the point? Better off carrying some sausages & a prong.
