A day after four workers died in two plant accidents in Nebraska and Oklahoma, authorities sought to determine what triggered the incidents while trying to recover the body of one victim trapped in the rubble, officials said Tuesday.
Two people died and 10 were injured Monday morning in Omaha, Nebraska, when the second floor of an animal feed plant collapsed. In Madill, Oklahoma, two workers died when a large industrial furnace exploded at a steel plant Monday afternoon.
A search and rescue team was working Tuesday to recover the body of one of the Nebraska feed plant workers caught in a pile of reinforced concrete and steel, authorities said. The body of a 53-year-old worker was recovered on Monday. Four people remained hospitalized.
In both the Nebraska and Oklahoma accidents, authorities said the triggers for the events were under investigation. Investigators were not certain if there was an actual explosion before the floor collapse at Omaha's International Nutrition plant, said Omaha Fire Department Battalion Chief Tim McCaw.
