JENKINTOWN, Pa. (AP) — Officials say schools are closed and residents have been ordered to shelter-in-place after a large fire broke out at an aerospace manufacturer’s facility in a town north of Philadelphia. Abington Township Police say the fire broke out at SPS Technologies in Jenkintown on Monday night and witnesses said there was an explosion and flames could be seen inside. Police say the building was evacuated, all employees were accounted for and no injuries were reported. SPS Technologies describes itself as a developer, manufacturer and global supplier of a line of aerospace fasteners and precision components. Schools in the area are closed and officials say the shelter-in-place order is in effect because smoke and particulates are filtering across the area.
