Default Extinguisher

You're right Rob....I've never seen one this long. I bought 2 of them. The second one being the usual size we're used to....but not a Pyreene Brand.
Thanks for your input...Robert

Yikes!

If it's full of Carbon Tet (tetrachloromethane, CCl4) that's not something you want to keep around, because it does evaporate and is fairly nasty stuff. (If used on a fire you can get carbonyl chloride (Phosgene, COCl2) produced depending on the flame temperature, etc.

Best regards,
Chris.

Default Ouch.....!

Hi Chris: Didn't know we had a chemist in the midst! I'll empty it out this week end and clean it out carefully, taking in your advice. Then, I just have to figure out what to do with it. Any buyers out there???
Thanks for your help.....Robert

Default Empty before shipping....

....but don't waste it........ a good canning jar or two will hold it forever..... and next time you have a french fry grease spot on your favorite garment use it to remove the stain....... it won't kill you ...........not right away!!!!! or clean the crap from the end of a starter you are rebuilding.....

Remember Robert....only good people die young...... you and I will be around for a while yet.

I was told once (not a chemist) that if you mix with water on a fire you can also get Chlorine gas.

As you say - nasty stuff - marginally better than getting burned though!

Worse than that, heat + water vapour + carbon tet:

CCl4 + H2O -> COCl2 (phosgene) + 2 HCl (hydrogen chloride/hydrochloric acid)

The idea of it as a fire suppressant is that it's heavier than air and will exclude oxygen from the fire, thus putting it out. The problems arise if it doesn't put the fire out and the temperature is high enough to break down the firefighting agent. (You then get toxic and corrosive gases formed.)

Even Halon can be ineffective on some metal fires... and the only thing you can put out titanium with is titanium dioxide - burying it to exclude anything it will react with, because it will break the oxygen out of water, carbon dioxide or sand, and the halogens out of Halon and just carry on burning. (If you can get enough water onto some fires it will work by lowering the temperature, but a spray won't do it if it's a big one.)

Chris.
(Remembering that someone had a garage full of 50 gallon drums of sodium metal that caught fire - an interesting problem for the fire crew and nasty for the local residents (including a friend of mine).)

I have also heard it's quite effective as paint stripper......


On the subject of extinguishers...I have seen brackets with 6 mounting holes and ones with 5 mounting holes......manufacturer difference only?? CMP rear walls are drilled for 6 holes if I am correct.

And that clamp.....my bracket doesn't have one, but I have seen people using the clamp of a repro jeep extinguisher bracket to merge with a Pyrene bracket.

I do recall reading a war diary entry which said it was great stuff to pump into the clutch housing if the clutch sticks.

Never tried it though.

Default It does work.....at least on a worn out M37

....so will road dust and starter fluid.....not a fix but enough to get you home using 3rd gear and high revs.....

We did change the clutch......oil was leaking from an overfull tranny ...passed the seal and into the input tube to the clutch pack......
