This probably sucks a little bit less than a fire at a gas station..

Think that's halon? That could cause serious injury!

 

If halon is dispersed as a powder, then this could very well be halon. Whatever it is, I would not have wanted to be in the area when that released. BTW - did anyone see what caused it?

Not halon. Systems like those require pressurization to function, as they have to reach and maintain a certain density in the air to suppress fire. That's just like some massive tanks of your standard dry chem from the looks of it. Either way, holy ****.

That seems to be ordinary powder, which essentially is same as baking soda. It releases carbon dioxide when heated.

 

An alternative would be foam which also works fine at fuel fires.

 

Halon is a gas and having it outdoors is useless.

That is not Halon. I had the halon system at one of my previous employers trip. Halon is an invisible gas that is simply more heavy than air. It works by displacing the air in a room but it would be entirely ineffective outside. I was told by one of the fire marshals that it isn't dangerous except in that it pushes all the air out and you'd be unable to breathe (if you were in said room).

Which is why they classify it as a fire "suppressant".:)

And actually Halon act's chemically active in addition to just diluting the oxygen level to suppress fire. Unfortunately Halon isn't good for the ozone layer so that's why it's outdated and often forbidden to use today. Usually it's replaced with carbon dioxide, which is almost as efficient. The difference is that carbon dioxide is a little more toxic for humans and animals and you will need a bit more of it.

 

You can also use any other non-oxidizing gas to suppress fire. Nitrogen, Helium, Argon etc. Just take your pick - when you have a fire it may be good to know that you actually can use the gas from your MIG welder to put out fuel fire.

 

But avoid chlorine and such gases - they can be even worse than oxygen!
