Safe storage of chemicals.

Students discovered a cylinder containing hydrogen fluoride (HF) that had ruptured inside a storage

room next to a laboratory. Following the cylinder failure, investigators learned of a letter DuPont

Fluoroproducts sent to its customers two and a half years earlier about the potential over-pressure

hazard associated with the long-term storage of Anhydrous HF in carbon steel cylinders. The

cylinder was a lecture bottle that had been stored at the university for 22 years. (OE Weekly
