Ogden firefighters quickly doused a fire late Tuesday morning at the Mount Ogden Junior High School. No injuries were reported.
Deputy Fire Chief Eric Bauman said the blaze was called in about 10 a.m. at 3260 Harrison Boulevard, where construction crews had been using a floor stripping chemical. An electrical cord suddenly sparked, igniting the flammable agent.
By 10:45 a.m., the blaze had been extinguished and crews were using fans to clear smoke from the scene.
