2 Safe disposal of LiPo pouch batteries
As with many here on iFixit.com, have had the occasion to remove a failed battery and replace it with a new one. I am well aware the LiPo batteries can become violent if mishandled, they don't seem to like being bent, punctured, over charged or over drawn. The question is what procedure should be applied to ensure you are safely storing, transporting and disposing of them?
I know there are recycling options in some places, but the battery may still pose a fire or explosion hazard while being stored and/or transported for disposal.
A short time ago 9V batteries came under scrutiny for starting fires after being thrown in the garbage. It is now highly recommended that all 9Vs be taped up to prevent the contacts from shorting against other conductors when disposed of.
So what should we do with the LiPos?
Is there a voltage threshold below which we shouldn't worry?
Would fully discharging the cell (past the limit board) render them safe from puncture arcing?
What about packs that have already started to go critical (bloated packs)? how long do you isolate them before the blast danger is significantly reduced?
Это хороший вопрос?

Most refer to the Google answers, and I have actually read them before posting. The question is/was, what are you doing as a pro with the batteries. Most I guess are doing some combination of the discharge and destroy methodology. Salt water has some support, and some criticisms, and sand pails seem to be the primary safety kit applied. I have also seen LiPo bags, and wonder what their effectiveness is. With the recent Samsung battery issues, this is seemingly a bigger issue for us to tackle.
