Fire/Explosion Due to Static

Explosion and Fire in a Sugar Refinery Caused by Static Discharge

Excerpts from news at MSNBC on that day:

"Sugar dust In a silo where refined sugar was stored before being packaged likely ignited like gunpowder. Sugar dust can become combustible if it's too dry and builds up a static electric discharge. The result was as devastating as a bomb. Floors inside the plant collapsed, flames spread throughout the refinery, metal girders buckled into twisted heaps and shredded sheet metal littered the wreckage."
