Punctured battery while replacing, help

As I was replacing the battery on my iPad 3 I accidentally punctured the battery and I have now (as of the time I am posting this) gone two days ago without touching the battery and leaving it in a place where it won’t catch fire. Is there anything I can do to take out the battery safely? It is also important to not that I took out the logic board and I was planning on replacing the battery anyways. The battery did also smoke up the first time and when I tried removing it more it caught fire. If I go back will it explode or am I safe?
