On Aug. 28, 2016, an Airgas employee began the process of transferring nitrous oxide into a trailer. A pump being used in the operation heated the gas above its safe operating limit, triggering the nitrous oxide to rapidly decompose in the pump.

The reaction then moved from the pump into the trailer and caused an explosion which killed the Airgas operator, scattered large metal fragments for hundreds of feet.

The facility also was badly damaged, and Airgas had to stop production of nitrous oxide indefinitely.
