From the archives: Chemists move wall with hydrogen peroxide explosion

More from my trip into the archives earlier this week. From Nov. 20, 1978: Explosive peroxides SIR: We would like to alert persons to possible hazards involved with the rather common laboratory procedure of dissolving electrophoresis polyacrylamide gels with hydrogen peroxide, in order to measure radioactive species by scintillation counting. Recently a very violent explosion…

From the archives: Chemists lose hands from peroxide explosions

Regarding the inadvertent synthesis of TATP at the University of Bristol, someone commented at “In The Pipeline”: I recall a C&EN story from the early 1980s about a group at K (Kansas or Kentucky?) preparing a batch of 100% H2O2. It exploded during purification and blew off a corner of the building. I vaguely recall…

How a student unintentionally made an explosive at U Bristol

Last week, the Safety Zone reported that a University of Bristol student had unintentionally made approximately 40 g of triacetone triperoxide (TATP), prompting building evacuations and a controlled detonation by an explosives team. Here’s a statement about the incident, prepared by Timothy C. Gallagher, a chemistry professor and dean of the Faculty of Science, and…

Color-blindness as a lab safety concern?

I was struck by these comments by a materials science graduate student who tried the glasses: “Primary colors seemed more their color,”…

Student unintentionally makes explosive at University of Bristol

A University of Bristol graduate student inadvertently synthesized approximately 40 g of triacetone triperoxide (TATP) on Friday, prompting building evacuations and a controlled detonation by an explosives team, chemistry professor and Faculty of Science dean Timothy C. Gallagher has confirmed to C&EN. No one was injured in the incident. The TATP was in solution and…
