If it reaches thermal runaway... there's not much you can do. There's simply too much potential energy in the pack. https://www.reddit.com/r/SweatyPalms/comments/1gbryd1/factory_workers_try_to_extinguish_lithiumion/ https://www.reddit.com/r/SweatyPalms/comments/1gbryd1/factor... Throw it in a massive body of water is about as good as you can do until the energy is depleted. (Also, making a human perform the puncture to initiate a violent chemical reaction is WILD. Do better) https://www.reddit.com/r/interestingasfuck/comments/1nuo0fj/the_safety_measure_used_after_a_large_lithium/ https://www.reddit.com/r/interestingasfuck/comments/1nuo0fj/... For real dev work... essentially special sheds with massive ventilation to handle thermal runaways, rated by amount of kwh.
