(Orrtanna) -- At least nine people required hospital treatment after a fire in a truck parked at a food processing facility in Adams County.
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 seven people were taken there for potential exposure to the chemical toluene. A spokesman says they were four emergency responders and three plant workers.
Two others were treated at Waynesboro Hospital in Franklin County.
John Eline with Adams County's Department of Emergency Services says an order will lifted for people who live within a half-mile of the fire to stay within their homes and keep their windows closed.
The chemical agent involved in the incident targets the respiratory and central nervous systems. Exposure through air or skin contact can result in symptoms such as fatigue, sleepiness, headaches, light-headedness, dizziness, memory loss, sore throat, coughing, wheezing, and nausea.
