The state fire marshal’s office has ordered -no- classes to be held on the third floor of Denison Middle School, due to safety concerns. Jeff Quigle, a spokesman for the fire marshal, explains the potentially-deadly circumstances. A student on the third floor would have to exit through four-foot-wide staircases and though a building that’s not separated by floor cutoffs. Quigle says if a fire were to start on a lower level, flames would sweep up through the building and compromise the exit. Denison Schools superintendent Mike Pardun says changes will be made to accommodate the middle school’s music program, which had been using classrooms on the third floor. Chorus classes will be held on the stage in the auditorium for now and the band will play there as well. The district is in the process of adding fire prevention measures and correcting problems.
