0218 hrs, the box was sent to the 100 blk of South Enola Drive for the reported building fire. Chief 20 arrived first to find a single story commercial building on fire with residential exposures and requested the box be upgraded. Truck 117 and Squad 20 arrived and went to work opening up and putting an aggressive attack on the fire keeping it to the building of origin. Crews from East Pennsboro, West Shore, Hampden, Camp Hill, Harrisburg, New Cumberland DLA and Duncannon worked on the scene for approximately 2.5 hours. A special thank you to Duncannon and then Marysville Fire Company for providing coverage while we were committed.
