JEFFERSON COUNTY, Missouri (KMOV.com) -- One man was severely burned and several others were injured at a Jefferson County fireworks plant Tuesday morning.
According to deputies, a 33-year-old man was air-lifted to a St. Louis hospital after he was burned at the Global Pyrotechnics Solutions on Sunset Drive and Highway Y in Dittmer just after 7 a.m.
Deputies said two men in their 20s were also burned. They were taken to an area hospital for treatment and have been released.
“Over the years it’s been a facility that made aerial displays for venues all across the United States for celebrations. I don’t know if it’s still the type of facility that is,” said Ralph Brown of the Jefferson County Sheriff’s Department.
In a press release, Global Pyrotechnics Solutions stated that there was no explosion and "raw materials used to manufacture a component of one of our products were ignited during the manufacturing process and caused a 'flash-over' fire."
ATF was on the scene and continues to investigate "an explosive incident" at the fireworks manufacturer.
