Seven people were injured in a hazardous material incident at Manheim Auto Auction this morning, according to a preliminary report from Northern Lancaster County Regional Police Department. The department issued a brief release shortly after 11 a.m. saying the Penn Township incident happened at 10:12 a.m. and the extent of injuries was unknown, as the people were transported to a local hospital. "The investigation continues with numerous agencies and resources on scene," police said. An email alert from Lancaster County's emergency dispatch center about the same time described the incident as an "unknown type leak." A subsequent release from police just after 11:30 a.m. said additional Fire Department resources had arrived, the building had been evacuated and "the initial survey of hazardous material has been concluded." The release did not offer any details on what the hazardous material was or what had happened, but said, "More information will be released when it becomes available." According to statements at the scene from Police Chief David Steffen and Joey Hughes, general manager of the auction's Manheim location, the building evacuated was a recon center, and employees there reported smelling a foul odor and then complained of headaches and nausea. There have been unverified reports that the problem may have been a methane gas leak, but Hughes said the auction doesn't have methane in the recon building. LNP records from 2016 show that the Manheim location is the world's largest wholesale car-auction site, with 1,600 employees registering more than 10,000 vehicles for auction per week.
