Exploding Experiment, No Injuries

UC Davis Report
Failure to maintain equipment properly has apparently resulted in another academic lab safety incident, but one that, fortunately, caused no injuries, reports Jyllian Kemsley at Chemical & Engineering News. On 23 January, undergraduates in a physical chemistry class at the University of California, Davis, were working with a piece of equipment called a bomb calorimeter when it exploded. (Despite its name, that is not supposed to happen.) The lid of the metal instrument was "forcibly propelled upward" until it hit the ceiling and other metal fragments and pieces of a mercury thermometer were sprayed into the room, according to a report on the event by a university chemical hygiene officer.
