Re: P.C's dont' really burn - Do they?
Actually, that's not the way that Halon works. That's how a CO2 flood works, which is the direct replacement.
See number 6 on here:-

6: Does Halon remove oxygen from the air?
It is a common misconception that Halon, like CO2, "removes oxygen from the air."
According to the Halon Alternative Research Corporation (www.harc.org): "Three things must come together at the same time to start a fire. The first ingredient is fuel (anything that can burn), the second is oxygen and the last is an ignition source. Traditionally, to stop a fire you need to remove one side of the triangle-the ignition, the fuel or the oxygen. Halon adds a fourth dimension to fire fighting-breaking the chain reaction. It stops the fuel, the ignition and the oxygen from working together by chemically reacting with them."

Halon is really, really effective at putting out fires. It really is incredible stuff that's the culmination of a firefighting dream; just drop a bunch of gas into the space and watch the fires put themselves out when it exceeds ~8% of the gas in the space with no damage or residue left on equipment (hence why it was massively popular in IT data centres, and aircraft)
Alas, it's also a CFC that does horrible things to the environment and new installations have been banned for like 30 years so it's a moot point. At this point you can probably count the number of installations left on your fingers!
