Summit has this system for 320 bucks. It says its Halon 1301.
I may be into something like that!

It must be a new Halon compound. We used to have them in computer rooms and we had to remove them by order of the EPA. That was years ago tho'.
Halon puts out a fire fast, with very little compound.
I bookmarked that link, thanks. I'm gunna' do that project after I finish my suspension build.
BTW: If you ever order from Summit Racing, you will have a great expeience with them. They are very efficient and have great communication. I've ordered several items from them in the past, and love doing business with them.

Ok well I service and install all types of Fire Extinguishers and Suppression systems. Basically a 2.5 lb ABC extinguisher is useless and do not pass any minimum Fire Codes. It's nice cause its small but thats about it. Minimum 5lb ABC but I would recommend a 10lb if you have the room. Any make sure there is a hose with the extinguisher cause these things don't work upside down or side ways. With a hose you can stick it in, point it up kind of thing. If you got an engine fire you don't want open the hood anyways right away. You want to just get the hose in there and fire the extinguisher off.
BC Fire Extinguishers are more effective on Flammable Liquids than ABC extingsuihers
Purple K Extinguishers are more effective than BC extinguishers
Halon is expensive and is to be taken out of service when inspected and can't be recharged so don't bother. This includes 1211, and 1301. The military are the only ones aloud to use this stuff.
There are Halon replacement clean agents out there. But these are more for Computer and Electronic equipment. These are not effective on fires outside and in low temperature. It takes the oxygen out of the air. Lots of that outside. And $$$$
If ABC powdered extinguishers are fired in an engine and it gets into the intake it will pretty much destroy your engine. There is metal in the powder than adheres to any hot surface. Not good for engines
BC powder is pretty much baking soda with additives in it to prevent caking
Look for the Rating on the fire extinguisher. It's more important than size.
Example a 2.5 ABC rating is 1A10BC. A 5lb ABC is 4A40BC
This means the 5lb is 3 times more effective at fighting Wood fires, 40 times more effective fighting Flammable liquids.
Oh and Don't buy a cheap plastic handled, plastic valve Extinguisher. Your rig is worth a lot of money. Get one worth with a Metal handle and internals. Amerex and Flag and Sentry are all quality Extinuishers.
Don't worry about the Powder packing or caking. Powders back in the 70's-80's did this. The new powders are siliconized(spelling?). Basically silicone is added to prevent this. Turning of an extinguisher and hammering on it is actually bad for the extinguisher and it can clog the syphon tube.
If you fire even a small amount of powder out of the extinguisher it needs to be recharged. It won't reseal.
Oh and Look at the date on the Extinguisher. It should be stamped on the bottom or on the Decal somewhere. Extinguishers should be recharged every 6 years no matter what.
As for suppression systems, I wouldn't bother. The off-road systems would be the only thing I would put on a Jeep. Any there's not enough room for a 25-30lb cylinder and you would have to get it serviced every year to make sure everything is proper. Halotron or Clean agent system would be useless in the winter if your in a cold climate.

a 5 pound is the best to carry but you need to remember to take them out of their holders every now and then and shake them as the powder settles in the bottom then is useless put them upside down and tap them with a rubber mallet or with your fist and make sure you get them tested every little while .

Um no. You don't have hit the extinguisher with a Rubber Mallet or your Fist. And hitting any pressurized vessel in a bad idea.

Yes this use to be a problem way back in the day but the powders now do have additives to prevent packing. It won't hurt anything doing this though but also don't help anything either and can possibly clog the syphon tube. It'll take very little time for the powder to settle back driving anyways. I've been servicing Fire Departments fire equipment for 9 years and I still get people asking wear my rubber mallet is. lol.

i HAVE ANOTHER EXTINGUISHER RELATED QUESTION. (sorry about caps)
We have a bunch of extinguishers at work and a lot of them were made in 1978.
Is there an overall expiration date on the unit past where it cant be recharged and used safely/legaly?

Good information JohnnyYZ, especially that the powder won't pack on late model extinguishers since they started adding silicone. What type shop would you suggest taking a 5 lb. ABC to for recharging? Can they refill it so it is a 'BC' instead of an 'ABC'? I'd hate to have my ABC cause engine problems if the dust were to be ingested into the air intake.

The Extinguishers at your shop from the 70's should be fine. They are suppose to have a 6yr maintenance done every six years and Hydro-Tested every 12-years, so the powder should have been cycled out to the newer powder. You can bring them to and Fire Safety place and they can do this for you. But Keep in mind that a new one is probably cheaper than Testing and Recharging these extinguishers. Odds are that these extinguishers are fine as long as they were not on a recall list. And they Can't put BC in a ABC extinguisher. Powders are also never to be mixed as chemical reactions between powders can increase the pressure in the cylinder and then Boom.

As for the Purple K powder, I have never heard any problems with engines and corrosion. The advantage is in the ability to extinguish the fire. I know it irritates your eyes, skin, and lungs more than BC powders. Keep in mind that Purple K is only rated for BC fires(Flammable Liquids,Electrical). ABC gets its A rating from Bonding to hot surfaces via the metal in the powder, thus cutting out the fuel for the fire.

My advice is to go with a 5lb BC extinguisher with a Hose with a heavy duty bracket so it don't fly and smack anyone in the vehicle. Purple K is great but hard to find.

Another great thing for wheeling is a Pump Tank. It pumps water both lifting up and pushing down the handle for a steady stream. Fill it up with water and find somewhere to mount it. It's great for cleaning the mud off of windshields, and tail lights, and putting out the camp fire. And if your passing a creek or a Lake you can always fill it back up. Cheap too, (They don't pass code no more so you should find em cheap). Conservation officers and park wardens love to see people with these also.

This is what they look like. They hold 2 1/2 gallons. You'll find the red plastic ones around everywhere. The steel ones are a little harder to find.

Interesting - the old codger that does the extinguisher inspections (and sales) for us once a year still walks around with a rubber mallet. He even told me to pop my vehicle can with a mallet every 6 months or so. Then again, he was probably part of the team that invented the extinguisher

lol. Ya that and there's not a whole lot to the inspections so you gotta look like your doing something.

Oh ya and here's what a Heavy Duty Vehicle Bracket looks like. These will not break, not like the flimbsy ones that break when you take the extinguisher out. Plus you can put a lock on it when the tops off when your not around the Jeep.


Another thing to think about is if you have alot of electronic equipment in the vehicle. Powder is gonna get into everything, and I mean everything, it is that fine of stuff. And it will damage electronics and is corrosive. There is a reason why they don't allow Dry Chemical Extinguishers on planes. Cause if one goes off they have to reskin the whole plane. Clean agent extinguishers are Halon replacement. These would work great inside the vehicle if ya had some electrical fires. These won't leave residue and are non-corrosive to electronics. They are also good at low temps unlike the old Halon.
It depends on the manufacturer put this one is called Halotron. They don't come with a hose until 15lbs I believe. Here's a 5 or 7lb I can't remember. These are only BC rated also.

Where would be the best place to find a 5 lb. BC to replace my 5 lb. ABC? Will I have to go into specialty safety/fire extinguisher supplier? All I see at my local home supply and hardware stores are ABC extinguishers.
