Danger-nixie strikes again
Two weeks ago my labmate asked me to help her evaporate chromium onto her wafers. That's all well and good, but when we were filling up a bottle with liquid nitrogen, the hose of the big tank became frozen to the bottle opening. I wrenched the hose off, releasing tons of pressure. A giant cloud of liquid nitrogen erupted from the bottle, and liquid nitrogen sprayed into both of our faces.
Fortunately, right when I was starting to fill it up, some man came by and berated us to put on safety goggles. Normally I ignore such warnings, but this time I didn't. I had a red line on my forehead for a week where the LN2 had pooled up above the goggles, and my hairline still hasn't quite recovered. My labmate (who was closer) emailed that her face was red the next day. She hasn't come in to lab since.
