Chocolate Plant Explosion

Ran across this article on ABC7.com about an explosion at a West Reading, PA chocolate factory. The page includes a nearby surveillance video of the actual explosion. One building was completely leveled, surrounding buildings were damaged, one reportedly moved 4-ft. Two people have been confirmed killed, numbers injured and they are still looking through the rubble for survivors. There is no information on the cause of the explosion, but it was noted that there was an active natural gas distribution line into the building. 

Again, according to the Chemical Safety Board, an explosion that kills people, severely injures people, or causes significant property damage is a reportable chemical release under 40 CF 1604. And, once again, this being a chocolate factory and not a quintessential chemical manufacturing facility, the owner may not be aware of their CSB reporting responsibilities, so I would not be surprised to hear that the incident was not reported when the next CSB report summary is published.
