Learn me fire suppression systems

So, at the swap meet today, I picked up a pair of charged and still good 10lb halon bottles with the pull handles. Only got one else nozzle though.

Seems like a prudent idea for the cprepared challenge car, as being set on fire is not something I want to do again. It sucked.

So, as this IS a challenge car (I know it doesn't count in the budget, but it still hits my wallet), I want to piece together the best, least expensive system is can. But I have no idea what the hell is am doing here. What lines? How many nozzles? In short, teach me everything.

Halon can kill you.

That's all I have to say.

Halon is no longer SFI approved and has not been for 17 years or so. We don't even use it in unmanned server rooms for a decade or more.

What you want is AFFF.

This for sure.

The way it was explained to me is the halon depletes the oxygen in the air to extinguish the fire. In an enclosed space it will extinguish you too.

Maybe not the case of you exited the car first?

I have one of these FIA AFFF systems. Never used it...hopefully won't ever...but I feel safe having it installed. I like the multiple nozzles, my previous one only had two. I also like having a pull handle inside the car and outside.

Halon, if done right, can extinguish fires at concentrations below oxygen deprivation levels. It actually inhibits ignition on a chemical reaction level. It's also been banned from manufacture for... 20 some years? I'd be shocked if they were actually Halon?

However, it doesn't do much good in open areas, and if it's overwhelmed turns into Bromic acid pretty quickly, so I personally wouldn't touch it unless it's a thoroughly engineered professional system.
