In Speece v. Borough of N. Braddock, 145 Pa. Commw. 568, 604 A.2d 760 (Pa. Cmwlth. 1992), declined to apply the motor vehicle exception to a case where Speece, a bystander, was seriously injured when a fire hose attached to a fire company's truck burst, swung loose and struck him. Our court determined that, although parts of the fire truck were moving at the time Speece was injured, such movement could not be considered "operation" because "both fire trucks were in stationary positions and were being used as pumping stations to extinguish the fire." Id. at 762.
