A liquid nitrogen leak at a poultry plant northeast of Atlanta killed six workers and sent 11 more to the hospital Thursday. At least three of the people hospitalized are in critical condition, officials said.
NPRreports local, state and federal police and health and safety investigators are looking for what may have caused the leak at the Gainesville, GA, Foundation Food Group plant. They cautioned Thursday it may be some time before they find out what happened.
The U.S. Chemical Safety and Hazard Investigation Boardwill deploya team of investigators and the board's CEO and chairman, Katherine A. Lemos, to the scene Friday.
Poultry plants use liquid nitrogen for refrigeration systems. The gas can causeextensive tissue damage or burns. Inhaling large amounts of nitrogen can cause dizziness, nausea, vomiting, loss of consciousness and death.
