The fire occurred when a naphtha heat exchanger ruptured, the report says. The cause of the rupture was high temperature hydrogen attack, which occurs when hydrogen atoms diffuse into carbon steel and react with the carbon to form methane. The methane...

When is an explosion really an explosion, take two

A few weeks back, we had a letter to the editor in C&EN that took us to task for using “blast” and “explosion” to describe two industrial incidents. We have more in this week’s issue (which, I might add, is a particularly awesome one in celebration of C&EN’s 90th anniversary). The consensus? The rupture of a nitrogen line is a mechanical explosion, and C&EN used the words appropriately....

A caution on procedures in organic synthesis journals

Organic Process Research and Development editor Trevor Laird, founder of Scientific Update, recently penned an editorial on “Safety Culture in Industry and Academia”. I’ll highlight one particular paragraph: Unfortunately, many companies and most universities are still not using the literature to find out more safety information (and not just MSDSs); for example, Bretherick’s Handbook of Reactive Chemical Hazards is...
