Station 72 was dispatched to WAWA on Mathistown rd for an electrical fire . The fuel island lights were sparking and had flames showing as per a wawa employee who was working fuel tonight . 7200,7201,7205 on location . 7205 backed in to the fuel island under the canopy for better position to check the lights that were affected . A thermal imaging camera is also being used to check for a heat source to pinpoint which hot spots better. There was a company power washing the underside of the canopy today . Water from that is possibly the cause of the issue.
