Around 6:00 am this morning Cool Springs with County Line to assist was dispatched to a vehicle fire on I-40. Chief 200 arrived on scene and advised we had a working fire in the cab area of a box truck. E1 arrived on the scene, the crew made a quick knock down of the fire keeping it from the box area of the truck. Tanker 2 arrived with additional water along with County Line Tanker 5. Great job by everyone involved!
