BELLEVUE, Ohio (AP) -- Investigators say lightening most likely started a chemical fire earlier this week at a magnesium plant in a northern Ohio town.
The state fire marshal's office ruled Thursday that the fire at MagReTech Inc. in Bellevue was natural. No one was injured in Tuesday's blaze at the plant, about midway between Toledo and Cleveland.
The office made its findings based on lightning strike data from the National Weather Service, the fire scene investigation and interviews with witnesses.
Four semitrailers containing scraps of magnesium were ignited and burned for more than five hours before the fire was controlled.
The company refines and recycles magnesium and supplies magnesium alloys.
The chemical fire forced schools in the area to close and police asked people to stay inside with windows shut.
