West Jessamine High School was locked down about noon Friday after a small amount of mercury was detected on the floor of the school's lobby.
Police and fire were called. The Clay Corman Excavating company in Jessamine County, a first responder for mercury spills, brought a mercury detector to check the shoes of each student, said Lu Young, Jessamine County school superintendent.
Shoes that had mercury contamination were placed in several large trash bags. "We had probably 50 to100 pairs of shoes," Young said.
The pace of checking shoes picked up after two additional mercury meters arrived from Frankfort. Still, the job was not finished until 4:30 p.m., Young said.
Never miss a local story.
The school will investigate the spill.
