Dupont officials told 12News Wednesday morning they are investigating exactly what caused an emergency shutdown at one of their polyethylene units at the Sabine River Works site in Orange.
The release happened around 11 p.m. Tuesday.
According to plant spokesperson Aaron Woods, the shutdown caused a spontaneous release which looked like a flash fire and felt like an explosion.
A 12News viewer reported seeing flames shooting 75 to 100 feet into the air. The woman said she lives about one mile away from the plant and that her house shook. She said she heard two explosions back to back.
Woods told 12News that everything was contained and there were no injuries.
He said the material that was released went through a safety system and that safety system worked as it was designed.
The plant was given the all clear at midnight.
