lithium battery fires - the way to do it
I am in the arff and i teach flight crew fire and smoke training. Lithium battery fires are dealt with thus:
1: extinguish any flame with BCF (halon)
2: cool with water (or any other non flammable liquid)
3: do not move item unless benefits outways the risk.
4: again, cool with water, lots of it.
5: monitor, check for transferred heat.
hope that helps
