That makes a lot of sense. If you put a few dozen packs in a TEU, you can disconnect that module and fog it with water if stuff goes wrong. A deluge on a pack running away will usually pull enough heat out to keep it from propagating. Now, you've ruined a container of packs, most likely (though auto packs are going to be decently waterproof), but you've prevented burning down a warehouse of packs.
