A worker who was severely burned in an explosion at an Imperial Sugar processing plant has filed a lawsuit, according to the Savannah Morning News. 13 people died in the explosion and resulting fire when sugar dust combusted at the plant in February 2008. 10 workers remain hospitalied. The woman's lawsuit alleges that the contractor hired to clean up sugar dust at the plant was negligent in performing its duties. A smaller sugar dust explosion in which nobody was injured took place at the plant only a few weeks before, yet housekeeping activities were not increased. The Savannah Morning News reports that the woman has received skin grafts and has been diagnosed with post-traumatic stress disorder.
