About 250 employees were evacuated and seven treated at the scene by ambulance crews in response to an unknown odor at an auto reconditioning facility at Manheim Auto Auction Friday morning, according to a written statement from the company.

"At this time, the building has been cleared by the Manheim Fire Department and Lancaster County HAZMAT, and we are working closely with local authorities to further investigate the situation," the statement released about 1 p.m. said. "Manheim is committed to protecting the safety of our team members, clients and guests.”

The company said six of the employees were taken to Lancaster General Hospital for observation, but did not release their names or conditions.

According to statements at the scene from Northern Lancaster County Regional Police Department Police Chief David Steffen and Joey Hughes, general manager of the auction's Manheim location, employees reported smelling a foul odor and then some complained of headaches and nausea.
