Halon or carbon dioxide would have the same effect. The danger is from asphyxiation due to lack of oxygen in the enclosed cockpit. Otherwise excellent fire extinguishers. Also used in aircraft. No corrosive damage.

I believe that this could be very, very dangerous! -Moderator Mike Substelny] I'm thinking about installing a built-in fire extinguisher into my DeLorean, and I'm wondering if anyone has any experience or advice concerning these. The only ones that I know about I found listed in the SummitRacing.com web site (as well as their paper catalogue I get snail mail.) These are a bit pricey ranging from $290 to $463, so I want to be really sure I buy the right thing the first time. It is basically a big 5 or 10 pound bottle of Halon 1211 that could probably be mounted inside of one of the engine compartment pontoons. There are two nozzles -- one for the engine compartment and one for the passenger compartment. It is activated by a manual pull or push activator. It would be nice to have something that could operate automatically, but I figure that most car fires happen while they are being driven. Is the steel or aluminum tubing to be preferred? Pull-type or push-type activator? A different brand? Or none of the above?
