There was also recently an ignition in a well-known hobby shop that we were informed of where a LipoSack prevented damage to the shop.

Jeez. But, good that damage is somehow limited.

That brings up an interesting question: What sort of fire extinguisher should one get for the hobby room? Apparently, CO2 isn't the best choice. Water maybe ? (Here in Europe it's considered safe up to 1000 V)

CO2 with the soda? may be ok, but it was the pressure that got me in trouble.
Some kind of a wide nozzle or fogging type nozzle may be what we need. Could be things would have gone better if I had not stuck the nozzle right into the crock pot. I got a very powerful blast, mostly because I wasn't thinking straight at the time. You know--You need to think about these things in advance.

Sand seems to work well.

You should be 6' away for most CO2 extinguishers which should have been fine in this case. Though sand is great, it requires you to get right on top of the fire, which is never a good idea. Halon extinguishers are ideal for electrical fires but most of the chemicals are out of production and not available for home use. Water has its own problems when you have a charger or 2 plugged into the wall.

At least you had a loud smoke alarm with good batteries.

Wonder how effective CO2 is on something which can produce O2 during decomposition. Dry powder might be the best bet.
BTW, you can burn magnesium in a pure CO2 atmosphere.

What problems? At least here in Europe, water hand extinguishers are safe for up to 1 kV. It's written on the extinguisher itself (keep 1 m distance) and the point was addressed when we had the last training a couple of months ago.

In regards to using sand. I have a 1 gal plastic bag full of sand. If the need arises I'll drop it on the pack. Hopefully it will hold the pack in place and extinguish the burning vapors...the pack will continue to self destruct releasing smoke (unburned electrolyte) rather than the electrolyte combustion products which might be more corrosive. I hope I never have to implement the plan.

Come to think of it, I'll test it the next time I have a pack that needs to be tossed.

I don't know if anyone saw is yet. While browsing for new toys on the RR forum, I came across these pics.
The lid from the brief case shorted out the battery.

Why is this thread still going? I personally think it should be locked, we have all seen the dangers of lipos. I think this thread gives people an opportunity to start fires with old lipos and think it's bad idea, also pollutes the environment. My 2 cents.

"Why is this thread still going?"

From the continuing reports of Lipo fires, reminders apparently are still needed.
In fact, some of the most recent fires occurred with balancing chargers....the kind that supposedly can't overcharge a lipo, .

(167) Pack on balancing charger ignites - http://www.rcgroups.com/forums/showthread.php?t=947656

There have been several threads started on "How I abused my Lipos" and they have been sent to the scrap pile forum. If you see any posts that you feel are inappropriate, just report them. I don't think closing an informational thread is the way to handle it.

hehehe and I could tell you what _I_ think

Of course it's a free world, and anybody is free to state an opinion.

In the 30+ year history of web forums (+usenet), making seemingly innocuous statements to bait people has been developed to a form of art. Just as a reminder, silence doesn't imply agreement

Yeah I agree you would think they would get the picture after the first 40pics and 20 videos huh...

You know people make the lipo vids just for this thread.
