OWENS CROSS ROADS, Ala. (WHNT) – Alabama State Fire Marshals are wrapping up their investigation into explosions at the Ultratec fireworks plant.

State Fire Marshal Ed Paulk says the explosions were the result of an “exothermic reaction which occurred during the manufacturing process at the plant.”

First responders and investigators from a number of agencies on the municipal, county, and state level responded to Ultratec Special Effects fireworks plant Thursday following reports of two minor explosions.

Following the incident, Alabama State Fire Marshals and agents with the Bureau of Alcohol, Tobacco, Firearms and Explosives conducted an investigation.

A press release from the State Fire Marshal’s Office goes on to say the employees were able to evacuate once they recognized the reaction taking place.

Ultratec was the site of an explosion that killed two people and injured four others in Feb. Sgt. Brian Chaffin with the Madison County Sheriff’s Office said that explosion happened during the fireworks mixing process.

After reviewing code requirements and cooperation with all agencies involved, the State Fire Marshal’s Office allowed Ultratec to resume production “subject to certain conditions and continued inspections” in late-March.

“Ultratec has been a good corporate citizen and has a good track record with our office,” Fire Marshal Ed Paulk said.
