Ah, so I see. My apologies, I usually start from JB, but not this morning. I really don't see the industry changing the halon systems anytime soon - I believe it is a legal requirement across the world. If you've ever seen a demonstration of a halon extinguisher dealing with a fire it's quite awsomely effective. Avalanch inhibition effect, I was told once. CO2 is effective, but you can't breath it without choking. Halon is all right for this, although obviously it doesn't support life, but it buys you valuable time to escape. Causes liver damage on prolonged exposure.
Flying balloons for pleasure, it has always mystified me why powder extinguishers are recommended for dealing with propane fires. I use mine as ballast and carry the green one to do any actual firefighting. Extracting powder from wickerwork isn't my idea of fun......
