Will I explode the lab?

A few days ago I asked if there was an easier way of sharpening
tungsten needles, which I use to hand de-chorionate embryos. I had been
using an electric current with a sodium nitrite solution; this set-up is
in another building and involves something of a hassle to have to go use.
Four people responded and all four told me that I could melt sodium
nitrite over a bunsen burner and that would work well. They also warned
me to wear goggles as the hot sodium nitrite spritzes. So I went over to
our chemical store-room and bought the necessary chemistry stuff (which
was really fun!) and did it and it worked wonderfully well! Ecept that
when the PI whose apparatus I normally borrow saw all of this, he said,
"Are you MAD? You could have blown us all to kingdom come! That stuff
'll kill ya'!"
Unfortunately, I didn't save the four kind responses, so I thought
i would ask about this, especially since my boss just saw the bunsen
burner and the goggles and the crucible with molten sodium nitrite in it
and asked another post-doc in the lab what this was all for, and since the
inevtiable "she almost blew us up" came into the conversation, I thought
it might not be a bad move to ask this more pressing q uestion, "Am I
really risking the lab and its assorted personel by sharpening my tungsten
needles this way?"
I guess the real question is, will I cease and desist even if it
turns out to be true? It was awfully fun!
