Gegen die Dummheit . . .Well, Guess Who Wins, Again
If you haven't heard about the explosion at Texas Tech earlier this year, this piece is the place to learn about it. (More from Chemjobber and the newly re-blogging Paul Bracher). In short, two graduate students were preparing a nickel hydrazine perchlorate complex, on far more than the recommended scale, and one of them was severely injured while trying to break up the substance in a mortar and pestle.
This is, as any experienced chemist could tell you, not a surprise. Call me when something like that doesn't blow up. But these weren't experience chemists. They were grad students, and I'm just glad that they didn't pay an even higher price for not realizing what they were getting themselves into.
At the same time, I find myself lining up more with Bracher's post, although I won't express myself quite as vigorously. The entire point of this research program was to look at hazardous energetic materials. The professor involved specifically told the students not to make more than 100 mg of material; they made ten grams. The injured student then ground up this material - yep, I did say "mortar and pestle" for real back there - with no blast shield, and gave the stuff one last poke after having taken off his goggles. He now gets to learn to write with his other hand. I can't figure out how he's still alive.
It's cruel, but one thing I actually respect about the physical sciences is that they have no regard for humanity. No exceptions are made; they respect no laws save their own. In a chemistry lab, we are dealing with the world as it really is, not as we'd like it to be. And if you want to believe that you can scale up the synthesis of a violent explosive by a factor of 100, despite warnings, and poke at the material without protection - well, you'd be just as well off doing it to a tiger. Perchlorates don't care what you think you can get away with, or how invulnerable you think you are.
