ORRTANNA, Pa. (AP) — Authorities say at least nine people required hospital treatment after a fire in a truck parked at a food processing facility in central Pennsylvania.

A Gettysburg Hospital spokesman said seven people were taken there for potential exposure to the chemical toluene, while a county emergency official said two others were treated at nearby Waynesboro Hospital.

Fire crews were called to the Knouse Foods plant in Orrtanna around 8:30 a.m. for a fire in a tractor-trailer parked on the property.

A Gettysburg Hospital spokesman says its patients were four emergency responders and three plant workers.

John Eline with Adams County emergency services says officials will be lifting an order for people who live within a half-mile of the fire to stay within their homes and keep their windows closed.
