A federal investigator on the scene of the deadly sugar refinery blast near Savannah says there was an explosion weeks before at the site. It was determined dust in a piece of safety equipment caused the earlier explosion--no people were injured in that incident. It cannot be said whether that explosion contributed to the deadly blast February 7th that killed nine people at the Port Wentworth refinery. It’s believed a build-up of sugar dust beneath the silos was the cause of the large deadly explosion.
