TOONE, Tenn. (AP) -- Authorities are investigating two explosions at a manufacturing plant in western Tennessee that injured an employee.
The first blast happened around 10:50 a.m. Saturday at the Kilgore Flares plant in Toone. The second explosion occurred around 9:30 p.m.
There were no injuries in that incident, but authorities said Kilgore employee Michael Chism suffered severe burns in the first blast and was flown to the Regional Medical Center in Memphis where he's listed in critical condition.
Kilgore makes air and naval decoy flares for the military.
Hardeman County Sheriff John Doolen said the company wasn't allowing authorities inside the building until the Bureau of Alcohol, Tobacco, Firearms and Explosives served a warrant.
Vice President and General Manager of Kilgore Chuck Stout released a written statement Saturday afternoon saying Kilgore would cooperate with law enforcement.
