On Monday, an explosion occurred during an organic chemistry lab at the
University of Maryland (UMD). The local fire department responded,
reportedly sending “16 pieces of fire, EMS and Haz-Mat units and about 70
personnel” to the scene. Two students received first- and second-degree
chemical burns and were taken to an area burn unit.
UMD chemistry department chair Michael Doyle tells C&EN that:
The evidence that I saw with the fire marshall was consistent with waste
material (strong acids) being inappropriately added to an organic reagent
bottle and not to a waste container. I believe that the lesson learned is
the need to segregate reagents for a lab from the reagents being used.
One of my colleagues notes that this is also a reason to be careful about
reusing old reagent bottles as waste containers–current reagents and waste
can be easily confused (although I don’t know if this was actually the
situation at UMD).
The fire department’s blog has more photos, although the post differs from
Doyle on the cause of the explosion |
