I wouldn't be in there without a respirator.
Just a little fire hazzard.
If they are lithium batteries then the fire hazard is of the order of 4000 degrees C, and my understanding is that the only way to put it out is to wait for it to burn out.Quote:

That's a really really really! bad idea.Quote:

For lithium metal batteries like these, a powdered copper filled extinguisher is recommended. (or graphite powder filled )
The powder starves it from oxygen, the heavy copper sucks heat up to cool it down.
Then let a professional do the cleanup.
Lithium Ion batteries are somewhat safer, but still, let professionals do the cleanup.
I know nothing of the professional opinion of extinguishing lithium fires, but as they found out at Chernobyl, ya'all cant extinguish a graphite fire.Quote:

Powder will act as a heat sink, while forming a crust that cuts off oxygen supply.Quote:

I reiterate, I know nothing of modern fire fighting methods, however, I HAVE seen magnesium flares quite happily continue to burn completely submerged in cold salt water, so heat sinking and smothering would appear to be futile, at least on magnesium. As to lithium, I don't know, maybe it's similar.
Try putting out white phosphorus when it is burning its way into a buddy's leg
Is this called "recycling"? Not great when some of the emissions could be HF.Quote:
