FLAGSTAFF, Ariz. (AP) — The production of pet food at a Flagstaff factory where an explosion injured four contract workers isn't expected to resume for several weeks.
Officials from Nestlé Purina said Friday that the ingredient intake and handling area of the mill building will need repairs. A damage estimate wasn't available.
Flames from welding equipment sparked the explosion Sunday, blowing out metal doors at the front of the seven-story grain elevator.
Plant manager Amy Kerr says the conditions of the four workers who suffered burns are improving.
She says Purina is gearing up production at other sites until its Flagstaff plant becomes operational. It typically produces 1,000 tons of dry dog and cat food daily.
The distribution center was unaffected. About 250 people work at the factory.
