    The Sangji/UCLA/Harran Case: Now Officially a Mess

    There have been a number of odd developments in the Sheri Sangji case, the lab fatality at UCLA that led to criminal charges being filed against both Prof. Patrick Harran and the university. The Doing Good Science blog at Scientific American has a thorough round-up of the latest. Last Friday, charges were dropped against UCLA… Read More

    Imidazole-1-Sulfonyl Azide HCl: Look Out

    I don’t know how many of you out there like to form azides, but if you do, you’ve probably used (or thought about using) imidazole-1-sulfonyl azide hydrochloride. This reagent appeared in Organic Letters a few years ago as a safe-to-handle shelf-stable azide transfer reagent, and seems to have found popularity. (I’ve used it mysel… Read More

    Potassium Hydride Is Not Your Friend

    Noted chem-blogger Milkshake seems to have had a close call with a fire started by a tiny potassium hydride residue. It looks like he made it through without serious injury, but that sort of thing will definitely shake a person up. I hate potassium hydride. Its relative sodium hydride is a common reagent, but it’s… Read More

    The UCLA Lab Fatality: Criminal Charges Filed

    Most readers here will remember the fatal lab accident at UCLA in 2009 involving t-butyllithium, which took the life of graduate student Sheri Sangji. Well, there’s a new sequel to that: the professor involved, Patrick Harran, has been charged along with UCLA with a felony: “willfully violating occupational health and safety standards&# Read More

    Charges in the TMS Diazomethane Case

    Readers may remember the case of Ronald Daigle, who died of exposure to TMS diazomethane a couple of years ago in Nova Scotia. Sepracor, the company who owned the facility at the time, has now pleaded not guilty to five charges related to this accident. (Many more details at C&E News). This case appears (slowly) Read More

    How Much is the PI To Blame?

    Chemjobber has a post up on the responsibility of the professor in the Texas Tech explosion case. I have to agree with him: if you’re going to get grant money to have your group work on energetic materials, you have to keep a close eye on things. And the C&E News piece on the whole… Read More

    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… Read More

    How Not To Do It: Hydrogen Gas Mixtures

    Culturing bacteria is usually a pretty quiet affair. Bacteria aren’t too noisy, and the equipment used to keep them happy isn’t too dangerous. But there are exceptions. If you’re going to culture anaerobes, you need somewhat more advanced technique, what with all that oxygen-is-deadly business. A professional-grade culture chamber… Read More

    More on T2, and Degrees

    Friday’s article on the T2 explosion has had a lot of readers, thanks to links from various outside sources. One line from it has attracted a disproportionate amount of comment – the one where I mentioned that the two owners of the company had only undergraduate degrees. This needs some clearing up; I should have… Read More

    175 Times. And Then the Catastrophe.

    I noted this item over at C&E News today, a report on a terrible chemical accident at T2 Laboratories in Florida back in 2007. I missed even hearing about this incident at the time, but it appears to have been one of the more violent explosions investigated by the federal Chemical Safety and Hazard Board… Read More
