Around 2330 hours Station 66 (Lancaster Township) and surrounding companies dispatched to 905 S. Queen Street at Penn Glass Inc. for a building fire. First arriving units encountered heavy fire in a vacant manufacturing building and quickly went to defensive operations. Aerial streams from Truck 2 (Lancaster City), 63 (Lafayette), 50 (Willow Street), and 66 (Lancaster Township) poured water on the fire in the initial stages of the incident. A partial collapse of the building occurred but no firefighters were injured due to a prior collapse zone being established. Companies remained on the scene for close to 5 hours dousing hot spots.
