Fire Chief Marc Bashoor said they had just arrived at the scene where a rescue squad and ambulance were already working a minor vehicle crash.

Just after they dismounted, a van struck the rear end of the engine.Units on scene extricated the entrapped van driver, who was transported to the hospital in serious condition. The three members on the engine were transported to a local hospital with minor injuries, but will be OK.The engine sustained a significant amount of damage
