ANSONIA, Ohio (AP): Authorities in western Ohio say seven high school students and two staff members have been taken to a hospital after a chemical spill inside a classroom.

A fire official in Ansonia says none of the illnesses are considered serious.

Ansonia assistant fire chief Dusty Brunner tells The Dayton Daily News that a small amount of a pesticide used to treat fruit trees spilled Tuesday at Ansonia High School in the agriculture room.

Nine people in all went to the hospital while several other several students were treated at the high school about 50 miles northwest of Dayton.

The building was closed afterward to allow firefighters to ventilate the school.
